GCodeCNC App – Work in Progress

Launch Icon

This week I made some progress with the GCodeCNC App. The App will be a fork of the GCodePrintr 3D Printing App, but optimized for CNC machines running GRBL. Icons, splashscreen and basic App customization work is done.


The layout for 10″ tablets looks good now, but there is still a lot of work . Many 3D print specific functions need to be replaced or removed. Special GRBL commands need to be added and parser for the response written.

But nevertheless, I can already use the App to control my Shapeoko CNC ! If you are interested in testing the beta, feel free to contact me by email.

Mini Lathe

I got a mini lathe for Christmas from ebay (~35€). It can be used for small wood pieces only.

CNC Wood Turning

After doing some manual wood turning, I tried the lathe together with my Shapeoko Mill to do some CNC wood turning.

In a few weeks I can post more about CNC wood turning…. stay tuned

Shapeoko CNC Mill Kit

Beginning of this year (2018) I joined the club of Shapeoko CNC machine owners 🙂

Assembled CNC Mill

I got mine from myhobby-cnc.de here in Germany. It took me a few days to assemble the kit.

My first test was some plotting using a pencil.
It took me a while to find the right cnc tools to generate the toolpath.
Most cnc tools (CAM) require Windows but I only have a Linux PC in my workshop. Pycam worked but crashed when reading a SVG file. I ended up using FlatCAM for Linux (meant for PCB milling) to do the plotting.

I designed a simple pencil holder with OpenSCAD and printed it with my 3D printer.

Luckily my GcodePrintr 3D Print App required a few modifications only to work with the GRBL firmware running on the Shapeoko electronics. My goal is to publish a modified version of the App for CNC milling (App name will be GcodeCNC). I’ll keep you posted.
