I am still new-ish to 3D printing (started last November) though I have managed to figure out and fix all the other issues I've encountered, but this one has me stumped. I'm printing with a FlashForge Creator Pro. My Simplify 3D version is 4.1.1
Anyway-- I used S3D for several months before I started seeing this problem-- sometimes with a model that I'd successfully printed/exported with S3D one or more times. It just stops-- usually somewhere between 45 and 99%. The nozzle stays above the print. Nothing else happens. The only thing I can do is cancel. If I try to pause and restart, nothing happens. If I try to print the same file again, it happens again in the same spot.
I tried to export the same problem models with FlashPrint and so far they have printed successfully every time. Also, it seems to only be happening with the left extruder. It seems to make no difference at all what material I'm using.
It does not seem to happen with small/quick prints (say under an hour) very often, but it has happened occasionally.
I'm using the same card for everything. I transfer to the card, then print. I do not print over USB.
I started troubleshooting this in early June, then stopped printing for a while (life gets in the way sometimes). Based on troubleshooting for the last few days, it has not automagically gotten better since then.
I guess I'm looking someone to point me in a direction that I can start troubleshooting-- Any ideas?
Thanks in advance for any help.
