Dual e3d bigbox. The bed heats up, then the head moves to the docking station. Both extruders heat up, but stay in the "heating" cycle, and nothing ever prints. running simplify3d with alex's profile https://github.com/Alex9779/BigBox-Settings running firmware https://jenkins.alitecs.de/job/BigB...fact/buildroot/Marlin.RC_Hybrid_Titan_MBL.hex
This is the first time I've ever tried to run dual extrusion. I was using a different profile before but this profile seems to work with 1 nozzle. Temps are fairly stable +/- 3 degrees
Are you printing from SD? If not the terminal output would be great. Unfortunately there is no way to make Marlin stop waiting on heating. You give the command and normally it should fail with an error after sometime. But I had that myself sometimes too... Mabye run a PID calibration for both hotends and choose values fairly between both results...
