Hello all. Been lurking for awhile but this is my first post about my MPCNC. Up until March I knew nothing about 3d printing or CNCs but a little while back I was fairly competent in Autocad back in the R10 and R12 days. Long story short, bought an Ender 3 Pro in March, started learning FreeCAD, saw this really cool MPCNC and figured why not give it a go.
Powered by an old benchtop PSU I had lying around.
Controller box with Arduino UNO and CNC shield
And my very first part for another project!!!
Honestly, this has been a lot of fun and feel free to point out anything I’ve done wrong, I really didn’t feel like I needed to ask any questions during the build. If I couldn’t figure something out, all I had to do was jump on this forum and do some searching. It’s a really great resource with a lot of helpful people.
The only difference is that I’m using GRBL for firmware and controlling it with a cel phone via a Bluetooth connection. I don’t have a laptop and wifi is a bit of a stretch in my garage. So far it seems to work great. I do have the issue of my XY gantry being slightly off but when I square it up and energize the steppers it prints square. My Z is also off by about a mm across the table but after searching the forum I opted to just run it for a bit and learn the machine before worrying about the bugs. It’s accurate enough for me for now as I start learning better CAM skills.
