Super Gerbil CNC Controller Accuracy Testing

We machined this simple acrylic disc to give us confidence that Super Gerbil was working accurately. It’s time to test the Super Gerbil CNC controller accuracy, so we designed some simple shapes in Fusion 360 and machined from some clear 4.4mm acrylic. First up, a disc with a design diameter of 25.00 mm in Fusion […]

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 […]
