Sometimes generated G-Code ejects filament

[hkindy]

Hi,

I am reasonably new to Simplify3D but I have had this fault happen to me several times. I use the printer with my Prusa I3 MKII. Many times I would generate G-Code and first thing the printer does after calibration is eject the filament from the extruder. This happens on a regular basis. I am not sure, but I think it is specifically triggered when I try to print multiple items at the same time. I have attached a sample of the g-code that is giving me trouble.

Am I doing anything wrong? or is this a bug in the software?

Thank you.

Hilmi

You might want to try going back to Help > Configuration Assistant, and re-downloading the stock profile for this printer. Then try some prints using that profile to see if the issue still occurs. That will help see if the problem is due to accidental settings changes in your current profile

Thank you,

That seems to have fixed the problem. I have had 3 days of printing without trouble.

Any idea what caused it?

There must have been a difference in your profile vs what they provide from the configuration assistant
