You have inspired me to get my own CNC'd G0704 back together. It was working great and I got the bright idea to extend the Y travel and never put it back together.
5 minutes in and I knew this video is the best available for this conversion. Thank you for the no nonsense crap, great documentation, and production value.
For anybody contemplating doing a CNC conversion, beware of the disadvantages of using a stepper motor that is stronger than necessary. This size mill requires a NEMA 23 270 oz-in motor, 76mm long with stock lead screws and a 54mm long motor with ball screws. One might think that bigger is better but not in this case. Having a motor bigger than necessary makes it hard to overpower with your hands in case things go wrong (and they will). It also increases the likelihood of damage if the motors are driven to the end of travel or if something is interfering with travel that you aren't noticing. Ball screws turn so easily that a big motor can generate tremendous force, far more than what is needed to feed a cutter into metal. Good job on this conversion.
i read thi comment and just thought WHAT DA FUCK
do you even have any idea what your talking about or any experience with cncs, othe than your crappy drillpress conversion 🤮
sure you might not need all of the power the nema 34 offers, but the limiting factor in cncs is ALWAYS regidity ,not motor power and you NEVER stop a cnc by just holding it 🤦♂️just hit the feed hold or e-stop
but if you send me a video of you doing that with a monoblock dmu 75 , vf-4 speed io or something similar, i ll delete this comment 🤣🤣
@@Basement_CNC Of course you lose your position if you hold the motors. That is not the point. Sometimes things happen too fast and you don't have time to reach a switch. With correctly sized motors you can overpower the machine thus giving a level of protection not usually available. I do have a RUclips video showing operation of the mill.
Big motor go brrrrrrr
Nice to see. I have been thru the exact same procedure with my ZX45 mill. It was about 4 years ago and I use it all the time. I have used this CNC-mill to build a CNC-router model hardcore.
One of the best videographers and instructor I've come across!
Best intro video that I have seen yet for explaining CNC control.
The small benchtop Wen lathe is doing ruclips.net/user/postUgkxKGVtPhqZBB5AQXXFlU2kdd4mQhO6wlhl just what it was desighed to do, turn small pieces. This product is workig very well in wood and plastics, I wouldn't recommend any metal turning on it though. Overall from an old tool guy, I highly recommend this lathe as long as you realize that this is for small turning only. I bought this a few weeks ago and have noticed the price has gone from $174. to $249. Might want to get one sooner than later.
I don't have a milling machine, but watched the whole video. Great job. I do have a homemade router CNC so I understood alot of what you were doing. Again great job. 👍👍👍👍
Very informative and entertaining video! Thanks for taking the time to make it and post it!
Thx for the vid. Was shopping their mills and this didn't "look" big enough for what I wanted. After seeing it in your shop, and you working on it, I think this will be perfect. I love having the option to upgrade it. Glad you went over it still being able to be used manually. I was concerned about that.
YOU ARE A GREAT COMMENTATOR!!!!!!
You really don’t need music unless you like it! This was a great video and project
Great video Jeff. I'm just catching up now on all my subscriber vids ;-). Thank you so much for the shout out I really appreciate it mate 👍 cheers Aaron
Thanks Aaron!
Great video! You make a CNC Conversion look a lot easier than other vids I've watched. We'll see if that turns out to be a good thing or a bad thing ;-)
I like the way that you explain things, it helps a lot!
I enjoyed the video, great narrative skills make it fun! Congratulations
I just found your channel today. It is very informative, and entertaining. You just got another subscriber.
Excellent video, it's inspiring . Thank you Jeff
Thanx , I seen a few of these conversions and yours is by far the best explaned and least scarry, I'm ready to go thanx again *o*
A hint for those dealing with the 3 bolts in the head... take them out, and wrap just enough tape around each bolt, just below the head of the bolt, to make them stay in position. I've done this several times, and it's a lot easier.
Yeah.I had the exact same problem replacing the brake master cylinder in my 73 Corvette...
very cool man! I just got a similar milling machine so it's nice to have this tutorial around :D
+Cactus! workshop congrats on getting a milling machine!
That end card with the CNC mill writing “subscribe” is so cool. Great video, thanks!
Great video. Good precise info without blowing minds.
Awesome conclusion of coffee brewing sustainment
Very impressive to say the least. Congratulations.
Thanks Harold!
How Incredibly valuable. Thank you.
an important and often overlooked part of any cnc conversion with ballscrews is to make sure the bearing blocks that the ball screws are fitted to on each end are of high quality. Considering that these bearings can easily add several magnitudes more error than what the ballscrews have if you buy the cheap ones its important to make sure you're using high quality bearings on the ends of your screws. These bearing blocks can go for anywhere from $8-$150+ depending upon the quality and kind you buy, ideally any with four opposed angular contact bearings of reasonable quality will be good enough for most builds.
Thank you for this, you are gentlemen and a squire
Outstanding video...you are a practical instructor!
Awesome build/project I almost attempted to build my cnc however all the computer components scared me out of if lol thanks for sharing with us well done tc
Lol. Tried to blow the shavings off by blowing at my phone. Why am I watching this at breakfast...
Time for coffee.
Thanks for the useful links.
Great vid👍🏻
Good job , bro; I think the bearings deserve a press fit . It shows when you run your indicator across a piece of work : the needle is trembling. Anyway, if one day that bothers you, you will know where that trembling comes from. Keep up the good work !
at 10:43?
awesome upgrade man
Great video, would love to do this myself. Bit of advice though, watch the program through before you try it on real material. And even better, get a usb pendant with a speed controller. This way you can watch a program through first time to make sure you haven't screwed the code up at all. Saves breaking tools and even worse the machine
Great Video Man! it was so hypnotizing!
Love it Jeff! Looks awesome.
Thanks greg!
Most people just buy the conversion parts bolt on and ready ( almost ) to go ; You had the machine and material and milled the parts yourself , well done.
Having battled with trying to align those 3 head bolts, I found the best way is to cut 3 pieces of thin plastic like a printer transparency, into 2 inch squares, roll them up and shove them through the holes in the head so they stick out the back. They then act as a guide for the bolts as you push the head back onto the carriage plate. Once the bolts are through, you can pull the film back out as the holes are quite oversized.
Awesome job, well done!
Ummm probably the best “voice” on RUclips. Great work btw. 👍🏼
Good job. I finished my own conversion with Hoss's plans a couple months ago. Now I need to figure out what I want to do with a CNC mill.
Ship it to me so I can cut parts to weld lol
Did you use something like this
www.ebay.com/p/15034911940
Excellent! My 704 is waiting for me to have enough free time to take on this conversion. FYI: I've struggled with the head reattachment much like you. You know what I discovered was a simple solution? A 3d printed bracket that aligned the screws in the exact position needed, and designed so it was able to slide right off when the bolts were aligned. Easy peasy!
Oh that's awesome, I'm assuming I can find this on thingiverse? I'm gonna go check right now!
Ok I've been looking for a couple days now and have to admit defeat, do you know where I could find this file, or at least a template I could whip something up from? Thanks a bunch!
I have a shop vac that’s attached next to the drill head to suck up the metal shavings as you drill. Helps a whole lot!
Really excellent project and video.
Great video - fantastic. Thanks very much!
"TNT" LOLOLOL.. made me laugh... I see that Hornady poster on hey desk.... 80% milling!!!! Awesome video Jeff.
very informative video great job.
Bravo! Excellent job!
Great video! Thanks for sharing!
Nice job. Inspiring me to do something like this
Amazing video! earned yourself a sub!
I always used the calculated steps per inch for my mach 3 settings. If you do it by just a test indicator you could be off by a few tenths but then that error will accumulate and could be off by several thousandths or more over several inches.
Why didn't I know about you or your channel before?! Subscribed!
Next upgrade is to exchange those gear boxes for 90˚ outputs so they don't get in the way so much. Very nice job!
I am in the middle of converting my x2 mill to cnc, I'm 3d printing my parts and installing them temporarily to use the machine to cnc my aluminum parts. That way I can check fitment and make sure I like the design first before machining it out of more expensive aluminum
Any issues with the 3d printed mounts? I'd think they wouldnt handle the torque of the motors without ovaling the bolt holes
great video. thank for taking the time..cnc rules
I had to take a double shot when you you said "double nut ball screw"😉
great video amigo, thank you
I give you props for doing this! But as an electrician I did get a bit of a laugh out of the electrical work but hey you got it done good job.
I like your Hornady mat!
What we learned. You have to have THOUSANDS worth in tools to be able to convert or plenty of disposable income to order already done or be a really and I mean really crafty person based on the plans purchased. Also, definitely not for someone who's a newb or not educated or has knowledge of operations. Now what I learned from the creator. You sir are effin awesomeness and kudos to YOU! First time power up and it works! Hell yeah! That's music to anyone's ears. That power box though. Definitely would have another fan added for cooling. You stayed on the side and stepped over the lines of caution and overdid and exceeded on everything else. You've probably upgraded since this video, haven't seen others yet. Definitely add more to cool. Great job my guy on every single aspect and level. 👍👍👍👍
Also.... I would also recommend some stepper motors with an encoder for feedback. If one of those motors loses one step, the whole job would be ruined, so, you'll resort to run it way below it's max speed. A Mach3 x11 breakout for a hundred dollars is also a very good purchase.
Man I really love that fancy grease.
Great work!
Hi folks. Three PSU's is a good idea. It avoids the three sets of driver electronics interfering with each other or interacting together to trip out one master PSU driving all three. Very sensible bit of kit. BobUK.
Well done Russ
i admire your skills sir
What a pleasure to watch - thanks so much for posting! Great editing, great comments, you held my attention for over 20 minutes! - not an easy accomplishment.... lol. I'm interested in an out of the box grizzly (or precision matthews) CNC mill. Any idea who I can contact that will provide an out of the box CNC at this level? I'm willing to tackle, but would love to skip if possible, the undertaking of a CNC retrofit. I'm just too excited about the projects I want to undertake with a CNC mill to have (as you said) a big appetite for a CNC conversion - but this video is the first to make me think it could be fun, and a super educational undertaking!! Thanks again! - Adam
Really well done man + 1 sub
Command thing about Machinists and Re-loaders by the looks of most video post on You Tube we all reload and build our own machine. Looks Good.
Great video!
Nice video bro
Excellent video.....well presented. Guessing you spent a considerable amount of time on it in the midst of a time consuming project.
I saw a comment referring to “Hoss”. Or is it “Haas” (as in Gene, Haas F1, Stewart-Haas, etc?). Thanks for the vid.
Dude you are a freaking genius
AvE references abound.
Very impressive. Honesetly, After watching this it makes me want to buy a tormach instead, but It all depends on how you want to spend your money.
Great Video!
Very impressive.
Can't stop watching your vid, I'll be an expert by the time I'm ready LOL. Great job! A bit off subject but, what 3D Printer do you use? I need a good one. Thnx Jeff
Nice ! I'm thinking about ZX7045 Chinese milling machine conversion . I just got it , fixed ( Sic ) and maybe I will upgrade it to CMC . cheers .
nice one mate
Good job! Your videos are very entertaining. Any plans to convert your Grizzly lathe to CNC??
Great Job
I had the same problem getting those head bolts lined up on my Bridgeport.
You deserve a big like ...
great job!
AWESOME
Sigh, I suppose I better get on it and get something like this.
Yess.....let the dark side flow through you.... 😉
You broke my heart the moment you said you can’t SHARE NUMBERS ..
Nice video!
Thank you!
Well done. .
I would suggest some stand offs under the breakout board and maybe even the power supplies. You need good air circulation around all the electronic components
I know this is an old video but, what a fantastic job, just wish I understood cnc to be able to do it
Hi, Great video! I'm new to this and I got a question. Do you think that using a brushless motor instead of a DC/ac motor for the spindle is useful to develop a CNC machine?
I have been converting my G0704 from Hoss Machine plans for at least five years. I admire that you got er done. I made the Y axis motor come out the back so it would be out of the way. It is only advisable to do that if you have a Bridgeport on hand as I did. For five years all I have had to do is complete the wiring. What is up with that? Thank you for this inspiration to finish the mill.
awesome video man! this gave me all the motivation I needed to not convert my mill to cnc lol..Also, how did you make the 2 color placard on your printer, change filament or spray paint after the fact?
Printed it out in glow-in-the-dark then spraypainted black, then sanded the face 😃
Descent work, nice idea
You are a genius, you make it look easy but I know it isnt.
I envy your patience.
Perhaps I missed it, but it looks like you're using software step generation instead of hardware (like a smoothstepper board). Not a huge deal, but it will let you drive the motors at a much higher frequency without losing steps. In practice, this means you can achieve much higher rapids, saving you alot of time in aggregate.
The probable reason the grease is so expensive might be because it is designed to work under heavy load and never have to be replaced but then again almost every type of grease put on bearings is for those exact reasons.
