3D Printed CNC Machine V3

This is the third version of my DIY homemade CNC machine. Instead of using threaded rods I'm now using (GT2) belts and it has a larger working area of 50x70 cm or 20x27 inch. By using belts it's also faster. To get a better understanding of the machine, also check the previous version here:
• Homemade CNC with 3D P...
I've designed the machine with Fusion 360 and also used Inkscape for the drilling template. To control the machine I'm using an Arduino UNO with GRBL firmware and an Arduino CNC Shield. There are plenty of tutorials to find on how to connect and use it so I did not show it in the video. Here are some useful links:
* [GRBL](github.com/gne...)
* [Arduino CNC Shield](blog.protoneer...)
If you want to build one yourself you can download all the necessary files on GitHub.
GitHub link:
github.com/leo...
The 3D printer I use is an Anet A8. The parts are printed with PLA, mostly 20% infill and 0.2 or 0.4 setting. Use higher infill for parts that must be stronger, for example the stepper motor mounts.
Dimensions:
The tubes are 20mm x 20mm (0.78") square steel tubes. The length of the Y Axis tubes is 1000mm (40") and the length for the X Axis is approx. 820mm (32"). As an alternative you could also use other dimensions than 20mm x 20mm (maybe even rounded tubes) as long as they are approximately that size. The Z axis tubes are 15mm x 15mm (0.59") aluminium square tubes, approx. 215mm long (8.5"). You should measure this for yourself, check the video build. For the belts I'm using GT2 6mm and pulleys.
The effective working area is 50 x 70 cm (20" x 27").
To power the NEMA 17 stepper motors I've converted an old ATX PC power supply and used the 12V output. The type of stepper motors I use for the Y- and Z axis are: 17HS19-2004S1, the type for the X axis is: 42BYGHW811. For the wiring I've used CAT5 network cable.
Software that I mostly use to generate and send GCode:
* bCNC (github.com/vla...)
* Universal Gcode Sender (github.com/win...)
* Easel by Inventables (easel.inventabl...)
* Fusion 360 with CAM (www.autodesk.c...)

hello friend very good tutorial, can you tell me what 3D program you use to design the plans?

[@LeonvandenBeukel]

I've used Fusion 360 for this design but for my next project I will probably use FreeCAD which I'm currently learning. The reason I'm switching from Fusion 360 to FreeCAD is the recent license change from AutoDesk. My guess is that Fusion 360 will not stay free software in the future. So if you're new to CAD and 3D design I recommend learning FreeCAD. Another reason to switch is that it's not easy to share designs as open source on for example GitHub. You always have to export to STEP files and later import.

​@@LeonvandenBeukel : Someone with a more informed source than I have might like to confirm the following; it is not from any official source, and I am not part of the "In crowd"... * There is an expense to Autocad where translators are provided to allow files from other systems to be opened or imported in Fusion 360. ( ie: NX, Catia, SOLIDWORKS, Inventor, PTC Creo, etc.). There is also an expense to them when they provide "one-on-one" support. * The translators (as far as I know) were not available in the Hobby/Startup licence that is to be replaced by the two new licences. ("Startup" and "Personal") Also, there was no support at a personal level. * If Autodesk are to "woo" users of other systems, they need to provide them with a way to continue using their existing files, and provide them with meaningful support. * The new "Startup" licence will (I think) offer this. * The new "Personal" licence will continue to lack translators, and will rely on forums and tutorials for support. For me personally, this is fair enough. Being given free access to software of this calibre is a real gift for a retired person who is not in a position to give anything in return, other than my heartfelt thanks. There is, of course, a benefit to Autocad from the "Personal" licence... Dad likes to "dabble" with CAD... Dad shows kids what he's done... the kids become fluent in Fusion 360, aided by a 3D printer... the kids look for jobs, and they can boast their competence in Fusion 360 in their application... they get the job, the new employer has reduced training costs...

I was on my way to order everything I needed to build a MPCNC, but I like your design much more. Well, back to square one on my research :D

[@clivetoogood1447]

Brilliant design, so I built A V3 with a few changes to suit my workshop. Printed all on Tronxy 802 (anet clone). I don't know why but had to rotate a lot of the stl files to make printing normal. Had a few mishaps along the way like over tightening bolts and breaking parts etc. Now putting limit switches on but your info is a bit sketchy on this so a bit of reading still required. One question is on the stl parts list there is a Z axis spacer that a cant find a home for. Found a nice way of adjusting y axis runners I tightened top 3 bolts but left the bottom enlarged hole bolts slack and then inserted threaded bars that holds top and bottom runners together (also slack) then put on a spare piece of 20/20 rail and used wood clamps until smooth and tight then tightened bottom 3 bolts up and tightened the threaded rods gently. Removed spare rail and put onto actual y rails. Mine went on beautifully with no more over tightened threaded bars to break or twist components. Thanks again ******Leon*****

Hi just want to say thanks for taking the time to share this. I have built this over the last few months during the lockdowns and its working great. I increased the size of the cut area to 80cmx70cm and its still good enough for the projects I've been using it for. I have been using a cheap Lidl trim router for now but will change to the Makita one for a little more power In the next few weeks. But just wanted to say I really appreciate that you took the time to build this and share with us.

I'm considering pursuing a similar design, although I'd like to use leadscrews.

[@pentachronic]

I thought about lead-screws but for long dimensional plot areas the leadscrews will sag under their own weight and will cause all manner of problems. I'm considering a chain version or a multi wrap cord drive system (eg 1 cord wrapped 5 times around a helix with a spring to keep taught (like the old drafting tables).

[@ktl0113]

Hey, thank you so much for sharing your excellent work, it is very inspiring for me! Can you (or anyone else) explain why you put the motors and steel tubes for the Y axis inside the machines work area? Why didn't you fix it to the outside like in your V2? I am thinking to build this version of your machine but to maybe put it on the outside in order to save some machining space. Also the tubes for the X axis would be a bit shorter and maybe more rigid. Do you think that would work, or is that a bad idea for momentum / power transmission reasons? Thank you!!

[@kenniffss]

I was looking at that too, I'm thinking that you would lose a certain amount of Y travel by putting the X motors on the outside. If you consider the cutting bit position in relation to the edge of the Z carriage I don't think you would gain a lot by reversing their position, maybe even lose some width..?

[@AdaptingCamera]

Why did you remove the screw drives and replaced with cheap rubber belts? That is a downgrade, not an upgrade. If you want to make a better quality CNC you must INCREASE the rigidity and precision, not decrease it. Those belts are OK(ish) for simple 3D printers, but they are not good at all for CNC. Higher speed is one thing, but the main purpose of a CNC is accuracy and repeatability. Those belts are not made for the load, especially when cutting. Threaded rods are much better, even if ball screws would be even better.

BobbyBoy1962 it took a while, over a week, I had a few misses and had to retry. But I basically tried to use all tubular steel, which worked great. I adjusted the sizes of the holes the tubes went into so that the center would still be the center wherever possible. The motor mounts I was able to use bridging to make them very effective and they work both as mounts and as bed stands. The biggest pain was marking and drilling the plywood for the sides of the xz axes and trying to cut everything out of the limited plywood I had. If Leon leaves a comment here that he’s ok with me posting on thingiverse I will and I’ll drop a link here.
