Okay, so this is definitely a firmware problem. Both extruders (and all thermistors) run perfectly as single extruders when running "M2Marlin24r2" firmware. My machine was manufactured in Jan/Feb 2013 and has since been upgraded to a 24v power supply and a V3B hot end. It has been running M2Marlin24...

I installed the dual extruder upgrade (very well made, BTW) and I'm encountering the following problem. When I fire up S3D, the initial readings from all three thermistors are correct, but all subsequent readings are so low as to trigger a MIN_TEMP error. Here's the output in verbose mode: Attemptin...

But I've tried several times to reply to posts and my messages don't seem to get posted.

I'd ask this of an administrator, but I also can't find a way to contact them.

Help!!!
