Using Marlin for Machines other than 3D Printers
Marlin is the most common 3D printer firmware in the world.
It is useful to adapt it to other applications so that the toolchain for constructing new civilizations is Degenerate.
Examples
CNC Torch Table
Use Lulzbot Cura - and turn on loads such as spindle with D8, D9, D10. Use M42 for IO pin control - such as M42 P57 S255 for an 8 bit full on for pin 57.
For D10, turn duty cycle to on/off instead of the PWM preset. To do this, comment out PID temperature control to go into bang-bang (on/off) mode:
//#define PIDTEMP
Firmware had to be modified as in - Firmware Modification for CNC Torch Table
Now use:
- M106/M107 - turn D9 on/off
- M140 S80 - turn D8 (bed) on to 80C. It should just stay on if there is no thermistor connected, reading 0C. To turn heat bed off, use S0.
- M104 S190/S0 - turn D10 on/off
- For I/O pin control - see G Codes in Marlin
