I an trying to build a completely from scratch printer and I am stuck on a really silly problem that I just can't figure out.
All my motors in all axes work, I am getting a reading from my thermistor, and my heater will turn on if I manually raise the control line SSR to VCC (or even 3,3v) but I simply can not get Sprinter to turn in on.
In my Pins.H file I have heater 0 set to pin 12.
#define HEATER_0_PIN 12
and I have my SSR set up to be triggered by that pin. In fact if I write a quick and dirty ardiuno app to raise pin 12 the heater comes on just fine, but if I load sprinter into the arduino and try to do it, either manually by sending a command like...
M135 P 0 S128
or if I use pronterface to turn it on it simply will not go on.
unfortunately the code in the heater section is a little beyond me and I just can't figure out what the heck is going on.
I am ready to print except for that. Everything else is hooked up and calibrated,
