Hello!
I’ve just finished upgrading my Fabool CO2 laser cutter to the Smoothieboard 5x v1.1. Wiring and config have been pretty straightforward, and testing some basics seems to work fine: I can turn the steppers on and off with M17 and M18 just fine, as well as test firing the laser with @Fire from within Pronterface.
However, as soon as I try the test G0 command suggested in the laser cutter guide, or try to home with the Gcode command, the board freezes entirely (unresponsive, LEDs cease blinking).
I’ve reduced the feed rate and acceleration from the default to 1000, which should be pretty conservative and not the cause of my issue. I’ve attached my config file below - motor setup might look odd, I have X axis on Alpha, and Y axis on Gamma with Epsilon as a slave.
Oh, also worth noting I’m running firmware-cnc-latest.bin
Thanks in advance for any helpful ideas!
