Flashforge Creator Max no extrusion after nozzle purge

[aackerman]

Apologies if I put this question in the wrong place- I'm new here...

I just bought the new Flashforge creator max, which is essentially the new version of the creator pro. I am having a problem where after the nozzle is finished doing its purge, there is no extrusion whatsoever. This problem only occurs with S3D as I've confirmed that the printer works perfectly using Flashforge's slicer Flashprint. In other words, no, its not a clogged nozzle. I've been using a FF creator pro for nearly four years with S3D and I've never experienced a similar problem. I've compared the gcode from S3D to the gcode from Flashprint and I can't find any differences. I'm fairly certain that the starting script in S3D is fine as everything executes perfectly (note I had to change a few things from default because the FFCP configuration was causing crashes on all axes during homing). I've attached my gcode from S3D in the hopes that someone can help me track down the cause of this problem.

Thanks in advance

Thanks for attaching your S3D generated print files. I'd suggest first looking at what a working G-Code file looks like for this new machine. You can quickly get this example to work from by using FlashPrint. I've included the first 50 lines of a 20mm cube sliced from FlashPrint. FlashPrint also doesn't export X3G files for this printer, so I'd say don't try to run those types of files.

To my eyes this code looks similar to the header used in the Adventurer 3 and Creator 3 profiles. I'd start there. In all honesty though you should discuss this with our support team.
