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 cards, you need to run LinuxCNC or MachineKit to talk to the FPGA controlling the CNC. so I download a 32-bit kernel of Linux (Wheezy 2.7.14) to an older dual core Pentium II PC with a trivial amount of RAM.

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

If you’re considering this upgrade, you should know that LinuxCNC is VERY picky about the computer hardware you run it on.

My advice advice to you would be to go read through all the forum posts on linuxcnc.org.

Pay special attention to all the information about GPU compatibility. Also, disable your computer’s power saving features and start with a computer that has only the bare essentials in it.

Getting stuck for three weeks because you didn’t notice how the after-market sound card was trashing your latency numbers isn’t a good time.

I hope you enjoyed this article. If you have any questions about my X-Carve or LinuxCNC, you can comment here or email me, and I’ll do my best to help!

X-Carve CNC Router

Okay, so I caved. The previous CNC machine was sold to pay for a new Macbook back in 2014, and it was collecting dust for a while so I didn’t feel too bad about getting rid of it… I saw the need to get a new router when I started brainstorming for my Full Body 3D Scanner V2…. I wanted to cut the huge pieces that were over 2′ in either direction on this new router.

I eventually decided to pre-order an X-Carve kit, and assembled it over a few weeks with my girlfriend! It works very well, my only gripe is that the GRBL firmware it runs off isn’t exactly real-time. G-code is streamed to the controller through a local server on my computer that relays g-code generated from the X-carve website. It’s very complicated to make this router 3D carve, but Mastercam should be able to create g-code for it!

Anyway, here it is!
