Hi all,
I have started this hackaday project to design a foam cutter controller.
FluidNC 4 axis foam cutter controller
Of course everything will be open source and open hardware.
PCB is under production at PCBWay and will be available there.
I’ll keep you informed on this page as soon as this project will progress !
current specifications are:
- able to drive a hot wire
- equiped with 4 bipolar steppers
- driven by standard polulu shields
- and with a “heart” ESP32 MCU
- FluidNC driven
- able to “eat” gcode produced by any “foam cutter” software
regarding this last feature I sincerely hope to test it with GRBLGru !
I have taken benefit of 11th/11 and bought the 4x drivers for less than than 4€ and 4x 1.5A NEMA17 bipolar steppers for 22€ (shipment included)
ESP32 costs less than 5€. So it will be a very cheap board
