Показать описание
Follow along as I go through my MPCNC (Mostly Printed CNC) build from start to finish. I cover all the important points of the MPCNC Assembly. The MPCNC is a home made / DIY CNC machine capable of using anything from a router spindle, plotter pen, drag knife, or even a laser cutter. Mine uses a router spindle for milling wood and even soft metals. I'm using TMC5160 Trinamic Stepper Drivers with my Bigtree Tech SKR v1.4 Turbo control board running the latest Marlin firmware, configured for CNC machining.

I fast forward through the mundane, and provide any necessary commentary. Sit back, relax and enjoy!!!! Links to the project, and parts that I used in this build can be found below!!!

Thanks for the video, I have a few questions if you can help please?
1) What gauge wire are you using to extend the spindle power wires?
2) What gauge wire are you using to go from the 48V PSU to the spindle driver?
3) Have you got any kind of wiring diagram of the electricals? Something simple, just to see whats connected to what (power wise, as I know each main board will have different connections) I'm just worried about making a wrong connection somewhere!
Thanks in advance!
