I'm so brand new at CNC that I haven't even finished cleaning up and reassembling the second-hand CNC I'm borrowing… this channel is proving invaluable. Thanks!
Glad to hear that 👍
Thanks I was stuck couldn’t get the z probe to work at all , after following this I got it to work and the first test was super accurate well done mate keep it up 👍🏻
Legendary tutorials, James! Just got one of these a few days back and your videos are gold! Such a fun machine to play with.
Glad you like them!
Wow! I just purchased the CAMXTOOL CNC GRBL, 2.8” Touchscreen LCD, Offline Controller which allows you to add user command buttons, and your video was so super helpful. Thanks a million.
Glad its helped :)
Setting up for Z-Probing I was facing my machine, not the control board. I accidently plugged the probe into the 5v slot. The bit messed up my probe ^^ After correction everythng went fine. I already watched a bunch of your 3018 playlist but now, when I got my machine, I'm rewatching it to set everything up. Thanks for your top videos and happy easter!
Awesome post, actually had a broken shelf bracket laying around that looks identical, I figured "if it is good enough for James....." Works excellent.
James, a very helpful couple of videos on assembly and first cut. I am trying to decide on a machine and your posts have me sold on the Prover 4030. It is just the right size for what I want to do and it looks easy enough to assemble and get up and running. I will be watching all of these a few more times as I move forward. A great help.
Thanks John. I think I just replied on Patreon but if you need any help just let me know
Thanks James. I’m going to make my own Z probe so this video is a great help.
This was immensely helpful to get my machine up and running. Genmitsu 4040-PRO
Glad it helped :)
many thanks as a beginner i have learnt so much you explain everything in a concise and easy to understand
Thanks for this video. All new to me but having fun. My 3020 Plus seem to be doing the job I need. PCB testing next.
Thank you for this and all the other videos! I couldn't find the z-probe controls in ugs, and knew you'd have the answer.
Glad I could help!
So glad I found your channel because you explain very clearly
Glad you enjoy it!
Your explanation is very complete and clear. Thank you
Glad it helped 👍
Thanks for all the info James
Hey thank you for putting this up! It's super handy!
Machine tune-up ---- WORKS
Built the z-probe ---- WORKS
Thanks for making both of them. Next project might be the box!
Excellent. Glad they helped 👍
Thanks James, another great video
Hope it helped 👍
thank you very much , this was very helpful for me.
Thanks man! Just sent you a fiver, subscribed and liked for the instructions. Getting my 3018 in two days. I'm sure I'll be back watching more videos and getting more instructions!
Wow! Thank you very much 🙏 hope your setup goes smooth but if you hit any issues just let me know
I bought a bundle of m/f Dupont connectors on 12in wires so I can splice/solder the wire to longer length. !
thanks mate, it was really useful
Thanks great explanation!
Great video, I think showing how you change the tool when doing a job would of been a god thing to show. Also need to find out how to set up the probe so it sits on the bed and not the work surface
thanks heaps u r wot makes life easy with cnc3018 . had no idear how to set up cnc till watching video and i have run much bigger cnc in kitchen fab . dan
Good contact with the wires is essential- otherwise the the bit will be driven into the plate; bad things can happen. A sprung plate with a max probe distance less than the movement gives you insurance. Best to measure the thickness with a micrometer- Vernier calipers are a bit approximate.
Thanks for the setting up process- made it quick and easy.
Definately and not just the wires. I had a tiny bit of MDF on the end of my bit and it failed to make the connection. Also why the travel distance should be kept as low as you can possibly cope with.
Thanks, this was helpful!
Glad it helped
Cool. I was hoping to find this functionality and see that the CNC feeds a measurement back to the PC. I was dreading writing them all down. Thanks, Dean.
Just sane :^) Saint
Concise and to the point (z0 point). ;-). Hey - one word of caution that folks like me who continue to use the broken imperial measurement system - In the “Probe Module” Settings tab, setting Units to Millimeters does *NOT* apply the “Probe Module” Z tab. For whatever reason I used metric to measure probe thickness, 12.3mm in my case. The “Jog Controller” was set to Inches, however. Upon issuing “Return to Zero” after zero’ing the probe, the machine took my 12.3mm input as inches and, well, of course the bit drove down into the bed. Ooops. I suppose this is obvious to most, but thought it might be worth calling out. Note to self : use metric in every setting to avoid such accidents.
Yes that is a bit odd. My log that as a bug on the UGS site to see if they can resolve. Glad my videos are helping though
Thanks James. Bought a probe but not tried it yet. Had a fire on my control board and been waiting for a replacement although still working on 12 volts. After several " fob offs " from the supplier, they've vanished so I bought one myself. Replaced the board today and upgraded the spindle as well. All running and ready to try the probe tomorrow. I didn't know it had the probe feature. I thought I'd have to write some code to run it so looking forward to giving it a go. Very useful info. Jim
Some suppliers are terrible with these things. I ended up taking mine through a PayPal dispute in the end as they refused to help me. Hope all goes well 👍
@@JamesDeanDesigns Yeah. Just write it off and carry on with life. New board seems good although different connectors for limit switches etc. But for about £25 ish I'm delighted.
Upgraded the power supply too.
I see some people say to step the motor speeds up in the program to stop it overloading the board.
Did you find that with yours?
@@flypic1098 Some board have been known to blow, typically woodpecker boards to my knowledge but there doesn't seem to be a particular pattern. It basically because the input power spike when the spindle fires up initially. I've never needed to use the code but some do. Alternatively you can get something called an inrush limiter which eases that initial spike
@@JamesDeanDesigns I'll just add a couple of lines of code when using high speeds.
Setting probe works great thanks James. Used the step up speeds in increments to reach top speed as well. Rather surprised by the spindle noise. It has the noise suppression on it and makes a loud screeching noise even at low speeds. If I stop the spindle with my hands it still make the noise. I know the noise they mean is interference with the other electronics but confused why it makes such a racket.
Your awesome. Thank you
UGS platform edition allows you to name your user command buttons rather than just Button 1, Button 2 etc.
Best part you can move & resize the panels around to optimal positions, see XYZ coordinates complete without having to scroll!
Thanks. Incidentally, double clicking any of the panel tabs will enlarge that panel to full screen. Double tap again and it shrinks back to its original size.
Thanks James.
FYI if you use Openbuilds Control and an Openbuilds XYZ Probe, they have a Probe Wizard which takes care of it all for you.
Nice. Thankyou
Are you using Tungsten Carbide 2 Flutes Ball Nose End Mills to drill the holes in the PCB?
Thank you James for yout tutorials. did you manage to use the Z-Probe with the offline controller for the 3018 PRO? do you have any guidance. Thanks.
Great Video James🎉. Just got one 3018 Pro a month earlier and it works well with smaller PCBs, but I'm facing issues with some bigger designs where the PCB seem to be not perfectly flat. Can you please suggest some solution to this.
Thanks for detailed video. Is it possible to have multiple z probe check for PCB milling? If possible please share how? Again thanks for the video
Paper works! (Just pulling your leg like in the FB group;).
I did realise it was a joke shortly after my response, I bit a little quick 😄
Hi James!
Excelent video, but I'm having some problems with the Z-probe in UGS. I'm using Universal Gcode Platform 2.09 SNAPSHOT / 2021-11-24, and the firmware is Grbl 1.1f. It's a Comgrow CNC Router.
When i click the "Initiate probe button" the bit is lowered down to the sensor and stops there. It doesn't go up and do a second slower sequence like in your video, but just stays there. Also, a new zero value for z-axis is not set, so it's kinda useless at this point.
Do you have any advide for me on how I can solve this issue?
You have some of the best and well informed videos that I've seen on RUclips and we thank you. I do have a problem with LASERGRBL that I hope you can help me with. I have a 3018 Pro that I am unable to speed up the feed on. When I use the machine for routing, it scoots right along appropriately but in Lasergerbl it is extremely slow. My S min is 9% and my S Max is at 11% and it still burns my plywood and makes a charred mess. I did make sure that my $ setting was set at 1000 but no change and the feed rate is at 2000 MM/min. Ideas?
As well as your $30 being 1000 you need to make sure your $31 is 0. Share your GRBL settings if you can and I'll take a look.
You can add a second probe line in Candle to do the two speed measurement as you did with UGS. I've made a three-way corner probe. It uses a variable in the first line for the tool diameter.
#100 = [3.125/2];
G91G21;
G38.2X-30F50;
G92 X#100;
G91;
G0 X5;
G91G21;
G38.2Y-30F50;

G0 Z2.15;
M30
Great tip. thank you
BTW, for future reference, assuming your #100 variable is for 1/8" bit. They are 3.175mm you might find you're off on X Y by A little. Not a lot in great scheme of things,
@@JohnColgan. oops. Typo. Sorry
Very Good
Hi James, thanks for your previous assistance, very helpful. Yet again I have a slight issue with UGS. On startup the programme display will not open as per your video, it opens in full screen mode and it does for each of the sub windows i.e visualizer, jog controller etc etc...Do you know if there is a default display setting somewhere so that I can view several plugins (I think that's what their called) on one screen at the same time. I have even re-installed UGS a couple of times all to no avail. Thanks again John.
I'll check tomorrow, there might be a reset view button. But you can usually drag the different windows about to make them how you want it to look
So I can buy the wires n crocodile clips which is fine. Where u have electrical tape at ends, how to connect to board? Do I just put which ever end on the z probe pins on board n use overhang of tape to hold it on. Ty for everything
If you are engraving onto aluminum (aluminium?) can you just hold one wire to the project and clamp the other to the bit and run the probe command that way?
I started using GSENDER software as I had a lot of problems with UGS. My cuts were mirrored due to an inverted Y axis, so I changed it in GSENDER and everything worked perfectly. I decided to try UGS and for my surprise all the coordinates of the machine got lost, like in negative position, the X0 Y0 position started in the X border, so everything is considered negative. I went back to Gsender and everything is correct, back to the center of the machine to the original position as I like to position home. Correcting firmware in Gsender is a breeze. In some video I found someone telling that UGS has negative and positive versions, is that correct? And what for would that be? Can I apply this video to produce my probe in Gsender? Thanks again.
THAAAAAAAAAAAAANKS A LOT 🌹
Hi James, I successfully touched the z axis, but in the second step I pressed G90 G0 X0 Y0
G90 G0 Z0 The machine dropped continuously and hit the wood.I need your help,Thanks James!
Thank you
I don't know how to go from my board levelling drawing in Ventric to applying the Z-Probe and then activating the machine to do the job. Am I missing those aspects in your presentation? Thanks
Brill, Thanks.
You're welcome!
do you have to do this test with every different thickness of wood
Recently I purchased a cnc a ttc450 it comes with a z probe, I have tried to use it but I'm having issues, i set the z probe command on the cnc but once I set it the machine starts the work 20mm over the material, what can be the issue in my case, I will really appreciate it
ok I understand the z probe and how to set that, but what about the x and y how do you set that so it know's where it is on the workspace mine never goes to the same place twice when i try to use it. my board has woodpecker on it and has 2x 2y and 2 z plugs on it whish one would I use, and is the x and y the ones I use the set the x and y of my cutting surface?? if any one could help me with this.
Great video - thanks. Just got a 3018 Prover and have been using your and Techydiy's videos to get started with it. Strange thing happened to me, though, after running the probe setup in UGS. The probe zeroing seemed to run perfectly, but after removing the probe and selecting "Return to Zero", the machine drove the bit down into the test piece of wood until it finally faulted and stopped. Happened so fast, I couldn't stop it. Only thing I can figure is that the jogging commands section was set to "inches" while the probe zeroing program was set to "millimeters" and the program didn't convert the z axis zero value? I ran it again after resetting the jogging commands to "millimeters" and it seemed to work correctly (although I was too afraid to try the "Return to Zero" command again) - I jogged the z-axis manually until it indicated 0 on the display and it was very close to the surface of the wood. I haven't calibrated the z-axis yet, so I'm hoping that takes care of the slight error I'm now seeing. Assuming that was the issue, just wanted to warn others about this potential problem.
I was facing similar issue to where when I probe z axis and zero out the z axis and run a job the job it starts few millimeters above the material, I have been told that zero z axis button is only used for manual probing like how they use piece of paper as a gauge, when you use an actual probe you just move the x and y axis to where u want on material (note this is done manually) and zero it out then hit the probe button, it probes the material then you just start the job and it cuts at correct height.
can you make a video of using the z probe for the 3018 pro plus thanks for the video and I have both cnc software you had in the video
:-) This guy is like a 3018 online manual. Bought a zprobe, come here to watch how to set it up!
😆 I try
I just picked up a 3018 pro but when I try to zero my Z (UGS) with the probe that came with my machine, The Z comes down , touches the probe then returns back up to the limit switch at Z+. I have set the retract height to 1 from 5 and no change. Is there a setting I'm missing in UGS or machine settings? I have set the home limit switches to -X, -Y-and+ Z during setup in UGS. It homes correctly with no issues and moves in the correct directions when jogging
Thanks!
Thank you Brian, thats very generous.Hope my videos are helping
Very informative. But I did not see any mention of where tomhookup the second wire on the control board. Did I miss it?
Connect the two probe wires to the two connector pins on the probe port which should be labelled as either probe or A5. It doesn't matter which wire goes to which pin.
Hi, thank you for the high quality and clear videos you being posting, i have an issue with the sainsmart 3018pro ver on probe setup, every time i do the procedures i watched on this video i never get the height of the prob i have, like i i tell the UGS or GRBL to raise 20mm seems like it goes half way, any ideia how to solve, thank you in advanced
Hi. Typically if its only travelling half the distance your steps might be out. These are your 100, 101 and 102 settings. If they are showing as 800 you may need to make them 1600.
@@JamesDeanDesigns Thank you for the response, but im new in cnc have you any video to explain how to do it?
Thanks
Hi, I finally have a computer to say hello. I have seen a CNC machine that I want you to look at because I'm a beginner still trying to figure out everything. Anyway, I will find the name of this machine and let you know the name of it. The construction of the machine is unbelievable. No, it's not a 3018 like my machine. I did actually get one of the better 3018 though. I will ask a lot of questions. And I hope to give good suggestions back.
I saw your Z probe spot when I first got my machine. Didn't understand how to what to. finally found it and understand it a little better. Still can't get it to home thought. Machine runs amuck. Hoping I can use Z-probe to make it do right.
Are those skip-ahead time codes in metric or imperial? Thanks!
;)
can this be done in the older ugs?
Hi James,
Can the software map a curved surface using z-probe ? I have seen some use aluminum foil over the surface to get close incremental measurements.
UGS can, called height mapping. People use it to make PCB boards I believe
Thanks! Answered some questions that the manuals don't directly address.
Glad it helped 👍
Gday mate, my probe control button won't save after pasting in your gcode, is there a save button
James, is there a way to turn the spindle on and off manually with having to type a code? I need to pause my cut some times when cutting foam due to waste foam getting wrapped on my bit. Need to be able to turn it off to clean the bit. Thanks
Easiest option to me would be to put an inline switch or rheostat and just turn the power off to the spindle when required.
Hi great videos haven't got my CNC yet but would like to build an enclosure for it I like yours have you got some plans for it so I can build it at the men sheds group where I go please
Yes I have, it can be found here with the plans as well. There is also a second video with some of the upgrades I made to it later on. ruclips.net/video/lTKdhGt8r5k/видео.html
This isn't a question about the z-probe, but looking at your screen of UGS, I see a tab labeled "Common Actions". I don't see that on my system and I think it would be handy. I just downloaded UGS and mine says Version 2.0.9-SNAPSHOT. Am I missing something?
I've watched a lot of your videos on using the Sainsmart 3018-Pro and subscribed.
There are different version of UGS as its open source software but the common actions tab can be turned on from one of the top menus like Windows I believe
I can’t find the files used in the description.
Great video. I entered "CODE FOR CUSTOM BUTTON" manually. I had to separate the codes with a semicolon. G90 G0 X0 Y0;
G90 G0 Z0
Thanks for your comment, it's helped me out a treat. 👍
Needed that extra bit of info. Cheers
Same. Thank you so much.
thanks for the video. Can't quite understand what the name of the connector is. Are you calling it a V point connector?
Sorry I followed your link for the connectors and got it. What a great informative video. Thanks for the available files with code.
Hello James. Regarding zeroing your Z axis, does this need to be done in the lower left of your workpiece, so that the X and Y are zeroed at the same time? Otherwise, when the Z probe is homed it won’t be in the correct position.
I say this because most probes are circular and don’t fit in the corner of your workpiece.
No, you can do the Z probe anywhere as long as the material is the same thickness. So what I typically do is get it into the corner, set the zero, then move in 20mm diagonally and run the z probe command
@@JamesDeanDesigns Thank you James.
thank you sir excellent video . I have one problem, when I am initiating the probe, while z is coming down to the probe it is giving me alarm error 9 and z access coming down too slow ! any help on this issue please deeply appreciated
Usually I think that means your bit is not close enough to the probe. It will only travel so far before it triggers the alarm thinking it cant find anything
When I click the custom button I'm getting an error:21 . I have a new machine Genmisu 3018 Pro
Interesting. I understood it is also possible to build a map of your workpiece that should cater for small variations in the zero surface: e.g. you are milling a pcb but your stock is ever so slightly bend
Thats correct, you can. Its called a height map. You can do it automatically in UGS
do you have a vide on this? @@JamesDeanDesigns
@@bermchasin no. Its usually used when doing PCBs which is something I've never done
If i have a crooked bed Can i do it at multipel points to make the program adjust to that crookedness?
Best method is to surface the spoilboard but I believe there is a multipoint function in UGS allowing you to essentially map the uneven areas
I realize this is a 3018 pro video, but i'm inquiring about the vacuum tube you have on your 4030 in this video. Is that on Thingiverse? If so, can you post the link. I can't seem to find it. Thanks in advance.
I dont think that particular design is on Thingiverse as the guy sells them on Etsy. Here is a link if your interested, I think he posts world wide tidd.ly/2Vlx7VM
hi james great video,i have a puzzle i am hoping you will answear for me ? i converted my 3018 pro to a 3040,my question is when getting limite switches do i order for the 3018 or the 3040,thank you
The limit switches should essentially be the same. The only thing I can think would be different is the length of the cables so you may need to buy the ones for a 3040
I have 6 Micro Limit Switches (3 wires: 12v,GRN and In) what do I have to do to Candle to make it work. The switches will be connected trough Grn and In, it means they will work as a switch. My machine is a CNC 318 PRO. I will appreciate some help. Thanks Raul
Hi Raul, Im not 100% sure as Ive never fitted them from new but usually you just have to adjust your GRBL settings to say that your using limit switches. Your $20 and $21 settings I believe are the ones that need to be turned on.
bonjour voila j ai un petit problème avec mon z probe. j arrive pas a le mettre a zéro et quand je lance le fraisage la broche monte au lieu de descendre. j ai une Genmitsu Proverxl 4030 et j utilise Grbl Cabdle 1.1.7
merci de ton aide
Hey hey can you please assist me?I’m having trouble putting the needle/tool in the spindle. The spindle won’t widen enough for it to fit in.
You need to make sure your collet insert is big enough to take the bit. There is usually a number stamped on the little silver insert stating what size it is. Its also sometimes easier to pop the insert out of the nut to put the bit in
Anyone having trouble with the command button? Error21? I had to put a ; between the Y0 ;G90 . Hope this helps.
Hi James thanks for sharing your knowledge I have 3018 pro i have followed your instructions in your GRBL video everything seems fine the problem i have is the z probe i followed all your instruction in video for the ugs part once i initiate the probe it measures as supposed to do but will not return home meaning it stops short of material any help would be great thanks in advance.
Is there enough thread left on the Z axis or does it hit a limit switch?
@@JamesDeanDesigns Thanks James i got it after reading the comments section i looked at my $ settings and increased $100 $101 $102 up to 800 seems to work fine thanks for the invaluable advice.
Can the z probe script in candle be modified to zero out xyz using a corner puck?
Yes it can. However I would highly recommend UGS or Openbuilds Controller as they have this feature already built in

James can you send or post the settings that you make for the shortcut number one button as I can’t seem to get mine to work after using z-probe. Thsnls

hi, I m using CNC3018 with grbl 1.1f, I am using FR4 PCB board as probe.after height map some of the tracks are still missing.what to do?. the steps are: after setting probe I am pressing XY zero and Z zero button then I create map, after saving map file I check the box to use same height map file for engraving.but still some tracks are not engraving.I have set 1.46mm thickness in probe command.please suggest me the solution.
Height maps is one thing I have not done but you could try using Openbuilds controller instead to see if that is any better
Help ! New to cnc and made a home made z probe , followed the video but when the bit touch’s the metal it disconnects my machine from PC and advice would be welcome , thank in advance Stu
I suspect the pins you've connected to on the control board are wrong or possibly touching other pins around it. Are they definitely A5?
Can you leave a z probe connected to the CNC controller board permanently and just remove the alligator clip after zeroing z?
Yes, that is perfectly fine 👍
I believe I have a supplier issue but wanted to get your advice. I have Gim. 3018 prover and everything works fine except z probe. When I set up and activate z probe the spindle comes down, touches, creates a small spark and controller trips ( all power is shunted). The spindle does not move. I need to unplug the PS to reset. Working with the supplier I have replaced the z probe and mother board with same result. I have used the off line controller in this test and Candle and USG. All had same results. Any thoughts or suggestions?
Sound like your Z probe is possibly connected to the wrong port. That's the only thing I can think of because it shouldn't be sparking otherwise
@@JamesDeanDesigns yes. Checked that and is consistent with pic in manual and has “probe” printed below. Also thought I was inserting probe connection up side down but the plug connection has barbs on underside that match with the board connection. What are the odds that I have two bad mother boards?
HELP! Using fusion 360 I designed a spacer I need out of a 6mm sheet of polycarbonate. The model has the origin at the bottom of the sheet. When I see the zero in Grbl, my 3018 treats the top of the piece as the bottom and never touches it.
I used a z probe and entered the height as 6mm thicker than it is and that worked.
How do I get the program to account for the thickness of the workpiece?
Love your channel. Very helpful.

Is there a way to add an offset in ugl?
Hi James wondering if you could help, I've set up my probe commands but after the spindle comes down and touches the plate the spindle returns up to far and and hits my limit switch 🤔
If you are using the code I provided, then the last Z command is Z5 which means it should retract 5mm. Make sure yours says 5 and not something else. If you still have the issue then perhaps try a different program as a test
@@JamesDeanDesigns Hi James I managed to sort it yesterday 😄 it was my fault I forgot the M after the 5mm Z retraction, so I had Z530 instead of Z5M30 I got there in the end, thanks for your videos though 👍🏽👍🏽👍🏽

Yes, basically the same for the 3020 👍
hey i bbought a china 3018... erslcam dosnt work on my board. will it work on your cronocontroller?
Estlecam requires you to flash your board in order to use it with their software. For that reason I don't use it because to be honest, there is no reasons for them to make you do that when all the other software runs directly without needing to make that type of change. It is essentially for them to tie you into their software
