Hello all,
I've recently swapped out my 12V power supply with a 24V power supply (and 24V heated bed). I removed D1 as noted in on the RAMPS 1.4 wiki and modified the current going to the hot-end with the "#define PID_MAX 64" setting. Everything is working fine, BUT when I instruct the hot-end to heat up (via prontrface) the RAMPS board starts making an odd beeping/buzzing noise and the hot-end LED indicator flashes.
Oddly, if I also heat the bed at the same time, the beeping may stop - although, the flashing LED continues to flash. I suspect this is a result of my use of the PID_MAX property. But I figured it wouldn't hurt to ask here to make sure I'm not about to fry something!
RAMPS 1.4
Marlin
Prontrface
Thanks,
Bobby
