Modified X-Carve and Custom 4-Axis CNC Controller

Here is my fully customized X-Carve!
I originally bought it in 2015 but I didn’t do much with it during College. Fast-forward to 2017, I found myself wanting a machine capable of handling demanding production run, better 3D carving, and to do it all on an Open Source platform as to make future expansions possible.

I quickly ditched the TinyG GRBL shield w/Arduino Uno and pick up some control cards from Mesa, specifically the 7i76/5i25 card combo.

With Mesa boards, you need to use LinuxCNC, so I download a 32-bit kernel of Linux (Wheezy 2.7.14) to a spare computer and got started.

The design files can be found by going to my GrabCad + Thingiverse pages –
