When I prepare to print, all looks normal, the bed and left extruder preheat and reach their set temperatures, but the FlashForge display says "temp 9%" and just sits there.
What could it be waiting for???

If I cancel the print, on the FlashForge, it is not clear how to get the S3D software in sync in order to try again.

What is the correct procedure for canceling a print??

I manually forced the right (unused) extruder to heat also, and when it got hot too, the job finally started.
So the job is waiting for the wrong extruder to get hot.

Well it's pretty easy to look through your gcode file and see what extruder the software would be waiting for. Just look for the M133 commands. T0 is right, T1 is left. So if you see M133 T1, then it's generating the right stuff. However, it's still possible that you have the wrong GPX settings which could screw things up. For example, if you tell it to heat the left extruder, but GPX thinks you have a bot with only a single extruder.

Look at your gcode and tell us what you see. Then check your GPX settings and make sure those are for a dual-extruder bot.

Having same issue with FlashForge Creator X. Had working setup with 2.0.1 and then upgraded to 2.1.0 now stuck with "temp %01" on top line. Printing with the left extruder only and tried the suggested trick of manually heating the right extruder, as soon as it reached temp the print started on the left extruder. The starting g-code sends "M133 T1" and the GPX machine profile is set for "Replicator 1 - dual extruder".

Well I would say that S3D is generating the right gcode then. If all you see is M133 T1, then that's the right command for stabilizing just the left extruder only.

I wonder if this is a problem with GPX or the firmware where it requires a setpoint for the right extruder too...
