Super Gerbil CNC Controller Accuracy Testing

We machined this acrylic disc as a simple initial test. Time to test Super Gerbil CNC controller accuracy. Using Fusion 360, we designed and machined a simple 25.00mm disc from clear 4.4mm acrylic. Dimensions of Sample Circle After that, we measured with grandfather’s old micrometer and my verniers. Grandfather’s micrometer is handy for measuring our […]

What did we learn during our One day build?

What we learnt during our One day build Today I will share some insights into our adventure while upgrading the cheap Chinese eBay CNC mill “3020”. If you haven’t watched the YouTube video then you can watch it here https://youtu.be/G_9dc0BAf0M The morning started for me at 7am and I was quiet nervous about the challenge. It […]

Nomad 883 CNC mill upgrade – controller and 4th axis

Let’s be 100% clear, I love my Nomad 883 CNC mill, it got me started with CNC.  Now, I’d like to take it further by adding a 4th axis, however this is tricky as the Nomad’s controller, and standard grbl, doesn’t support it.  Fortunately, Paul’s developed a brand new ‘Super Gerbil’ 5 axis CNC controller (now […]

The 3020 / 6040 CNC mill 1 day upgrade challenge

The 3020, 3040, 6040 and 6090 are low cost no-brand CNC mills that come in various 3 or 4 axis versions, but suffer from underpowered electronics and poor software.  So we’ve created the Super Gerbil controller as a high quality upgrade to the electronics and software tool chain.  For a bit of fun, we’ve challenged ourselves […]

PPA Calibration

PPA calibration refers to discovering and setting tuning factors for electromagnet timing. It is performed to: While the default calibration figures usually work well, in some cases, the default tuning factors need to be changed to get reliable rotation on your PPA, and/or Achieving highest possible speed operation of the PPA Finding the best tuning […]
