Rumba has no support for directly connecting a Thermocouple, you need a thermocouple amplifier chip and feed the output into one of the ADC inputs, eg 'MAX31855 breakout' product eg [reprapworld.com]

If you didn't say "When I move the z axis up or down it moves in the correct direction" I would say you just need to change the #define INVERT_Z_DIR true setting. You may still want to do that. But...

If description is accurate only cause of this is Z home feed rate to high, and basically its trying to move but failing and bouncing back, actually moving backwards

RC-2 is so old I don't even remember it. Please cross your settings over to RC-8's RCBugFix. I think you will feel it was worth the effort.

For running a laser you sure don't have to set the #extruders to "0", because you only need X and Y.

Yeah... I'm all for making what ever weird hardware work. And Marlin does support a very wide selection of hardware. But at some point, it is easier to spend $20 and get the same hardware that 1/2 the...

It almost sounds like you have a mis-match between your Configuration.h settings and the Slicer settings. It is important your slicer knows the exact #define X_MIN_POS, #define X_MAX_POS, #define...

View ArticleRe: Dual stepper drivers on for single axis on Megatronics
If "dual Y" is acting the same as "dual Z" then the first unused extruder port is used for the second Y stepper. In your case E0 and E1 would still be extruders.

Thanks, I got the same tip from the Marlin Github. I thought it would only go to E1 as per the comments on the firmware code.
