Using my CTC3d printer loading and unloading TPU filament I've found it much easier to use Simplify3d's jog control panel rather than the printers "load/unload" options. One behavior that I find odd is that sometimes when I select toolhead 1 and extrude the X axis moves towards the endstop (to the right) while it extrudes. It does this very slowly, and if I manually hit the endstop it stops moving until I release it.

You may wish to look into your firmware configuration. Any time I manually extrude with my second extruder my assembly stays in place.

I have this exact same problem with my PowerSpec3d PRO (Flashforge creator pro clone) If I try to extrude my tool head 1 (left tool head) it moves the carriage to the right. I will also note that the left x jog control does not work at all. All jog functions work perfectly in ReplicatorG.

I stand corrected!

Extruding 100 works for me. smaller increments do all jog a bit to the right.. interesting.

Yes, this is a known firmware bug. Only happens if you try to extruder with T1 extruder selected.

Not sure if this was ever fixed in newer firmware versions or not...
