My apologies. I got so excited seeing this thread that I didn’t read THE VERY FIRST POST, ug, my bad. The Kickstarter link was there. Anyhow, this is awesome cool. Looking forward to seeing how it evolves.
Thanks guys for your comments. And, yep, those are T8 Acme rods. They are not perfectly straight but good enough. David – the CNC motors do sing a bit when running code. It’s a very familiar sound to me as well.
I built a MPCNC a couple months ago and had a blast working on the project. Printing the parts and studying how it was designed was pretty awesome. And then last winter I built a Solsylva CNC out of wood and gas pipe and also enjoyed that build. The more I looked at both machines the more I wanted to take from each and make a unique CNC using…[Read more]
I’m learning too each time I turn any of these CNCs on. It’s magic that any of it actually works. And, yes, the cost for building the MPCNC was incredibly low compared to the other CNCs. From the moment a decision was made to start printing the parts to the time when it was completely up and running was less than two weeks. And that was just…[Read more]
That is beautiful work. You really have that one dialed in. I’m sort of old school in speeds and think in inches per minute – so the IPM on some of my other machines when cutting plywood has been in the 50 to 80 ipm range. When I was using the MPCNC and cutting some 3/4″ plywood last weekend I had to drop it down to around 10mm/sec, or…[Read more]
I know this thread is a few months old, but I’ve been wondering along similar lines. The MPCNC that I built works fantastic on foam, moderately well on thin wood with a 1/16″ end mill, and not so wonderfully with a 1/8″ bit on thicker wood. If I slow the machine way, way, way down I can cut through 3/4″ ply but it’s still not real pretty and it…[Read more]
Yeah, NEMA 23s for the MPCNC is not a good combination for a variety of reasons; weight, heat, torque, balance, etc. When I first looked at building the MPCNC I also thought of trying to use the 23s I had here but quickly realized that was not smart. The 17s are more than strong enough.
As far as driver boards and wiring up things there are…[Read more]
As far as simple software for my CNC projects I use Inkscape for all the design work, and then use jscut (www.jscut.org) for the CAM part of it. Both of these are free and they play extremely well together.
I have some tutorials on this for CNC stuff on my YouTube Channel at “drez20001” This was an easy project using both Inkscape and jscut.…[Read more]
Over the last week or so I put together an enclosure box around my MPCNC to cut down on the dust. It was built with a lot of scrap I had around; nothing fancy. The last thing to do is to connect a shop vac to the rear of the enclosure. Even though the center assembly is really beefy, I didn’t want to attach anything to it and create extra…[Read more]
@ Bryan – Ummm, wiring; well, I didn’t use an Arduino set up. This is more of an old school set up using Windows based stuff. The Toshiba board is really only designed to run three motors but I’ve doubled up the x and y on one driver each. (NOTE: This was a duh, moment on my part – since the motors are on opposite sides of the CNC you need to…[Read more]
Well, we have an operational MPCNC with a pretty large 2’x3′ cut area! The project took about two weeks from the start of printing parts. Many thanks to Vicous1 for these awesome plans. Instead of a router I dropped in a 500 watt spindle; so much quieter and for $135 on Amazon it seemed worth it. I also used a TB6560 control board and am…[Read more]
Forgive me if this has already been mentioned or worked out, but when I find an image online that I like and want to cut or engrave it I do a screen capture then bring it into Inkscape. Once in Inkscape I do a bitmap trace and then manipulate the image. Once that’s done it can be exported as an SVG for coding.
I want to tinker with Estlcam,…[Read more]
Found some time this evening to tinker. My old Toshiba 6560 controller has dip switches and when I drop the current down to 25% the motors stay comfortable. Just slightly warm to the touch. I let them sit idle for close to an hour and they were just warm so I think we’re okay there. I also tested the drivers on the Toshiba board with doubling…[Read more]
