Charlie your the only one i have found that shows how to set it up in Mach3,
Thanks '
Rich
Very welcome
Hello Charlie. I feel I owe deep thanks to you. I have 3040Z-DQ machine. Trough your videos and your 3D files, my "homing" works like a charm. You did a great job.
Awesome! Glad it worked out for you.

What a star you are.
I've been having a mare with setting up limits and direction on jog keys from Tab button.
X reversed like you did on other video.
I've watched all of Arts videos. (Designer of mach3) I think.
And he assumes were all computer engineer's who built it with him and misses obvious parts to him out like how to reverse if necessary.
Thank you kind sir.
I've definitely subscribed.
Great. Glad you got it working. Thank you for the compliments.
Nice little machine, Charlie!
Short quick but very informative.
Love it "It won't let me crash"
Another great video, thank you!
Shaun Whiteley Very welcome!
Nice explained ! And that laugh .... :)))) Thumbs UP !!
You are rocking that little 3020... and a 3d printing monster on the loose...
+Web Surfer I just have way too much fun sometimes, lol.
Your music sounds like the action sequences for a Mega Man game... I love it. Thanks for helping me indirectly get my 3020 machine up and running :) Even tho my controller board is a different model, your videos helped me get my homing switches and spindle relay control operational! Best of luck Charlie, and keep posting videos on anything you find helpful, because these have been that (and some) :))))
Awesome! Glad the videos have been helpful.
2:05, GOLDDDDDDDDDDDD!!!! Thank YOU!!!!
Charlie, you mentioned that your cnc is set up inches, I had to select mm to tune motors , would you mind describing how to setup the cnc in inches
Great info, many thanks
You're welcome. Thank you and glad you enjoyed the video.
Hello
Can the laser be installed instead of the engine in the CNC 3040 4 axis Router.
Is the electronic circuit has a place to install a laser cable.
Thanks you for this Video This help Me out Big Time!
Awesome! And you're welcome.
I need all of that.
Is it possible to setup soft stops for both directions with out using the micro switches?
What controller board is in you control unit.
Awesome tutorial. Do you have maybe macro for homing?
Glad you enjoyed the video. Not sure what you are asking for exactly. Mach3 has a built in macro for homing with the "REF ALL HOME" button. The macro for this button can be edited if need be. If you need help, let me know.
Charlie
Great job again... What 3d printer do you use?
+Steven Galloway JGAURORA A3. It's a kit that I purchased on Amazon. My Spool Center video has a link to it if you need it.
Thanks mate !!!
Very welcome.
Hello Charlie , have a cnc 3040 , works fine , but a month ago , start the Mach 3 and its an alert, SWITCH LIMIT TRIGGERED. And dont let me reset the stop bottom. The axys dont move. Can you help me please.
i have a 3040 mini cnc engraving machine Z-DQ controll box try to hook up limit switches i see the pin connection the box how di wire
+Joel Chavez
Not sure of the differences between your control box and mine, but the writing diagram is in the video. Remember to wire the switches Normally Closed (for Active High signal).
Greater job sir
Thank you.
Charlie why did you choose to place the X & Y home switches in -x- and -Y- positions? What did I miss here?
They are set like the standard 1st quadrant Cartesian coordinate system. Maybe it looks weird because unlike a standard mill, the routers y axis is not a table movement. I think that is what you are referring to. If standing above the machine, x0 y0 is lower left.
I'm using Normally Open Hall Effect Limit Switches on my CNC Router and am wondering if they should be configured in a Active Low Configuration by Default. Any assistance would be greatly appreciated.
Ronald Lambier
Yeah, if the switches are wired Normally Open then they will be setup Active Low. If you use the Auto Setup of inputs, as in the video, the mode will be detected automatically.
Thanks for your quick response.
Ronald Lambier
Very welcome
Mr. Sarsfield , I've been trying to get this CNC router engraver to work properly for over a year now and it is still running weird. The gentry on -x- moves the same way even though I'm pressing { + or - } and the gantry will stick in 1 place so I'm losing place in the project. This is a CNC engrave 3040
with a 12mm screw , 12 tips per. 1", 2 mm angle between threads and I'm have trouble find the proper speeds for the motors. I payed a tech $100.00 to help me and -HE DID- but he said " my machine is junk. Could you offer some input to these problems?
Is there an error at 0:28 regarding the X connection?
I have the same machine I need to learn how to do this
i have a breakout board with USB connector. how can i define my limit switches?
please help.
There are a couple different ways to setup and wire the limit switches. I have only worked on my machine, so I'm not sure how to accomplish it on other setups.
thank you,
You're welcome.
Hi Charlie
Thanks for the video, really helped. However, I got little problem I can not solve.
Mach 3 recognise that the switch on my Z axis has been opened only once! Looking at the diagnostics tab, I can see that the little yellow indicator representing the switch, stays lit after firs press and no matter what I do, I won't turn off.
I have to restart Mach, it's off again. I press the switch manually, the yellow button lits up but stays on again. As a result, homing isn't working on the Z axis because Mach sees the home button constantly pressed (opened).
I tried "noise filtering", didn't work, I'm out of ideas here.
Thanks
Jay
Provided that the switch is good, the wiring and connections are good, and the settings are correct, perhaps try routing the Z Axis wiring further away from motors and gang wiring, if you haven't tried that.
Have you tried another switch? Have you tried wiring the Z Axis normally open (change settings to match) to see if that makes a difference?
Just throwing out things here to check.
well, I just found out that the problem persists even when I disconnect the switches from the controller and "jump" the pcb pins manually.
Why could this be happening?
Thanks, Jay
Is it only the Z axis giving you problems, or X and Y also?
It was the only Z but more I dig around, Y started playing up as well. Not as bad as Z but there is some few seconds delay before the status LED goes off.
More questions... Are you using a parallel port cable from PC to Controller (as in NO USB connection)? USB could possibly be an issue as Mach3 was not designed for it. Also, Is the operating system on your PC 32 bit ? 64 bit is not recommended for Mach3.
Do you need power to the switches or is it just a case of plugging one wire ie red to the in2, in3 or in4 and the black to com
In my case, I just wired it to the locations shown in the wiring diagram for my board. The wiring diagram I used for this project is in the video at 0:27 seconds.
@@sunny5rising my board is different and I can't find a good wiring diagram lol board is a JDSW43R-USB
If you type that number into google, you'll come up with a pdf manual. The manual that I found doesn't exactly show limit switch connections, but it does look like one connection to either in1, in2, in3, or in4 and the other connection to ground (0v).
@@sunny5rising yeah that's what I did and I think I found the same one as you lol I suppose the easiest way to find out is connect it and push the button lol
Input value soft max (X, Y, Z) is from??
From bed size and Z travel sir??
First, I sent the machine home. The axes were then set to zero. Then I manually moved all axes to their maximum safe positions and used the numbers from machine coordinates DROs to set the soft maximums. In the Z, maximum is zero and the minimum is the lowest point of the stroke (Z Neg) of the machine. How this helps.
How can I adjust the machine limits without limit switches?
I don't know for sure that you can, without limit switches. Might be possible if you move the machine axes to a given spot then zero all. This would be your machine zero. From here you would set up the soft limits as in the video. This method won't give you the accuracy between shutdowns because you have to re-zero machine zero every start up. That's my two cents, lol.
Dear Charlie, you mention in the picture "Wired active high" what does it mean?
"Wired Active High": It means that the limit switches are wired Normally Closed and the Mach3 input pins are set Active High (Voltage is present throughout the switch circuit). Under normal running conditions, Mach3 expects to see constant voltage through the switch. Once the limit switch is pressed, the switch opens and the voltage is cut, triggering the event.
"Wired Active Low" is the opposite. Switch wired Normally Open. Mach3 Input pins set to Active Low (No voltage present). Once the switch is pressed, voltage is present and triggers the event.
Hope that helps,
Charlie
@@sunny5rising thank you for your clearly explanation
It still will crash on at least two occasions, the cable isn't shielded and if one direction skipping steps due to blocking fi and the other will move then you have recepie for disaster to bounce into the hardware
Perhaps, but fortunately I have not had any of those issues.
hello i have 6090 model i connected rotary axis with my machine but how can i set soft limit for the rotary axis i tried but not done what should be its max and min soft limit as i am new for 4th axis
Usually you do not want limits for the rotary. In Mach3 General Config, uncheck Rotational Soft Limits.
thanks one more thing when i set slave axis to y axis in general config setting i cant able to rotate 4th axis by my keyboard what are the issues
Slaving the rotary axis to another axis will cause the rotary to only move when you move the axis it is slave to. It's not a normal setting. Do a search on my channel for Rotary Axis Configuration. This video should help you out with the rotary.
sory but cant find out pls send me the link
ok is slaving the axis is necessary for rotary can i use without slaving it
i click in automated setup of inputs and i get a message that says: This is only for the printers modes!, how do i fix that?
Oh wow, I have not ran into that issue. My Mach3 version is R3.043.066. If your version is older try downloading the latest.
Charlie Sarsfield i have the same version, im connected via usb though, also i´m having troubles setting the vfd, i cant make the spindle work via mach3 (click in spindle cw f5) but when i click cycle start the spindle starts running at 8000 rpm i think and i can´t change the rpm
Seems lots of folks have issues with the USB/Mach3 combination. Wish I had a USB version so I could look at some of these issues first hand. I did do a spindle hack video awhile back, but I'm connected via parallel port, used an on-board relay, and I manually control the rpm.
bonjour Mr très bonne vidéo explication précise avec vos photo montage votre modification est t'el envisageable pour une carte JP-382A
Unfortunately, I haven't looked into the JP-382A card, so not sure.
Hello friend you know how is for the model USB because the screen mach3 is different
I wasn't aware that there was a different screen for USB. Did you download a special screenset for that?
nice vdo,,,i want to make it at home but have no iedia how to start
If you haven't done so, watch my first 3 videos in this series (they may help you get started). If you happen to have the same machine as mine, you can download the models to print (model links are in those videos descriptions).
I WANT FIRST ALL EQUIPMENT DETAIL THEN PRICE AND WHERE TO PURCHASE AFTER IT HOW TO SET AND INSTALL,,,I AM COMPLETELY NEW SO I HAVE NOTHING IDEIA.
hi , how to set table in mach3
What exactly are you referring to?
ok
Hello Friend. I am in a project to make a cnc table. I still have to wire the race limit switches that go to the card. I have a diagram of the card and the limits. You can help me ? I can send it to you by email. I would greatly appreciate it
Im amazed that 3D printer hardware has come so far, 32 bit motion control and everything, yet CNC mills seem stuck in the dark ages of 2003 software and using janky kernel timing to run. I really dont get it XD
There are upgrades I believe, but I personally have no problems with my setup. It does everything I tell it to, lol.
Oh nono im not meaning to insult, If it does what you need it to then fantastic why change it... Im a total noob in CNCland, but would respectfully say that im pretty experienced in 3D printing. Im just surprised the 2 very similar communities have diverged so drastically.
Worry not, I didn't take it as an insult, haha. Myself being new to 3D printing, I was pleasantly surprised with the differences in setup compared to a CNC mill. With that, I think I understand what you are referring to.
An easier way is to wire them all in series that way you use less wire and only need one input .
Yes, that will also work. If, however, you want to use the RefCombination() Function (as seen in one of my later videos), you will need the individual inputs for the homing switches.
@@sunny5rising You don't need individual inputs for homing. I have 2 CNC's set up that way and I can Reference All Home with single input.
Yes, you are correct. We agree. I was talking about RefCombination, not RefAllHome.
@@sunny5rising I haven't tried setting up that way.
that's what she said XD
Isidoro Maich You're silly man, lol.
THROW THAT ALUMINUM EXTRUSION TABLE AWAY AND PUT A 1/2 INCH STEEL PLATE AS YOUR BASE THEN EVERYTHING YOU DO ON HERE WILL BE MORE RIGID
Definitely an idea to consider, but haven't had any problems as of yet with the aluminum bed.
