Good electrical grounding of your K40 laser is critical to correct and consistent operation. While grounding is a safety feature with respect to dangerous voltages, this article focuses on effective grounding for the K40’s low voltage DC circuit. Please consult other resources to ensure that your K40 is completely safe. Due to the linkage to […]

When replacing or upgrading your K40’s controller, how do you choose the right option for you? In this K40 controller desktop review, we cover your options. You are here… M2 Nano board Our K40 controller review starts with the M2 Nano board which looks like this. M2 Nano board from Lihuiyi It is the standard […]
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 […]
A part of our upcoming toy truck, used as a demonstration of Super Gerbil CNC controller It’s testing time for the Super Gerbil CNC Controller pre-production units! We put them through their paces with a testing regime that’s included a wide range of activities: Installation – technically correct and user-friendlyConfiguration – technically correct and user-friendlyAll the basic […]
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 […]
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, 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 […]
Yes, we’ve got our exciting new toy, ah, I mean, serious prototyping tool: the Prusa i3 Mk3. First, there’s the unpacking at Paul’s robot room. Watch the IKEA style packaging! Then, the basic frame And the y axis and bed And the x axis Really coming together now, with the all important extruder assembly […]
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 […]
