I’m using +42V and +5V supply from Isel power brick to power Isel step drivers (X and Y). I also added MW switcher to get +12V supply for Ultimaker motherboard. Next step is connecting Y axis and adding stepper drivers for Z and extruder.

This is my design of an extruder for filament in wire shape. It is designed to precisely extrude plastic wire with 1.75mm in diameter. Extruder will be used on Isel cnc machine capable of driving 2kg spindle with high speed acceleration. Weight wasn’t an obstacle so I made it heavy duty.
I’m using small stepper motor with integrated gearbox which reduces it’s rpm and increases torque. Wire meets the gear with sharp edges which pushed wire further through heat sink to hot end.
