I'm using QIDI i-Mate S (similar to the PLUS) and Overture PETG.
S3D does not have a default PETG setting. Should I try the ABS setting? PLA setting too cold.
I'm new to this. Trying to learn and listen without being bothersome. I'm not going to use the QIDI slicer any longer. I'm using the S3D software, NOT the QIDI slicer.
I've just taken delivery of my i-Mate 2 days ago, I'm in the process of fine tuning PLA FFF.
Use the PLA setting and adjust the Temp = 230-235 experiment as filaments differ slightly, start with the lower 230C, cooling 40% for now.
First "Save as New" will open a popup which will read "Qidi Technology i-mate" just add to it PETG and hit OK, this will be the go to profile for your PETG print tuning. When you come to do ABS or PLA or any other filament type just load the default and rename it after the type of filament to easily load different Process.
Make sure you have levelled the bed using the provided card, I found I needed to lower the bed by -0.05 as the Bed was closer once it heated to 60C.
Import your model, in S3D go to "Show advanced" then click "Edit Process Settings" in the pop-up window select "Additions" make sure "Use Skirt / Brim" is ticked.
Change "Skirt Offset from part" to 10mm and "Skirt outline" to 5.
Key "Think always of the Bed moving closer to the Nozzle" ignore the saying "moving the nozzle closer to the bed"
Start your print and stop it and cancel it after the 5 lines are printed or even after the first layer only, after the table has dropped you can now examine the "Skirt outline" to see how close the "Bed is to the Nozzle".
If the Outline looks a bit transparent you'll need to lower the bed, either by "levelling the Bed again but skipping straight to the "Middle position which has the "Offset" option +0.05 or -0.05. or in S3D "G-Code" tab "edit Z Axis by -0.05.
Since you are new to S3D try only doing this in the printer until you are more comfortable with S3D.
There're other Options that can be used under the "Tools" tab but it would just make things too complicated for you just starting with S3D.
I hope this leads you in the right direction and I'll be very happy to help if I can.
