Based on the images and information you provided, it sounds like you are experiencing a problem with overextrusion on large radius features when printing with your Raise3D Pro2 printer using 1.75mm Ninjatek Cheetah filament and slicing the model with IdeaMaker.

This could be caused by a number of factors as you can read some printers information, such as the extruder not being properly calibrated, the filament diameter not being set correctly, or the extrusion width not being set correctly in the slicer software. To fix this issue, you may want to try the following:

Make sure that the extruder is properly calibrated so that it is extruding the correct amount of filament.
Check the filament diamete
Check the extrusion width
It's also important to note that this is a complex issue

I think your problem is NOT PETG but rather printing in general.
Entire print all around looks like crap and you expect it to bridge nicely ?
Good luck with that.

After years of printing i made up one rule:
Rule #1 If you cant get 1st layer perfect, dont bother printing the rest.
Rule #2 Obey Rule #1

Your prints look like crap at 1st layer, why do you even continue with the test ?

My PETG prints came out better then ABS or PETG.
With little FAN it makes it look even better.

Hi there @duoltd3d

Thanks for joining the community, you are in a bit of luck as I know the Raise systems quite well. Your first print does look quite good and in your case, I think that it would be best if you just let us know when you had any questions. I always try to pop in here every day or so to help out and offer up answers on some issues.
