This is my first time printing with PETG, I have had a ton of successful prints using PLA. I was attempting to print https://www.thingiverse.com/thing:3495390 but I already was having trouble just with the prints skirt. So I switched to a more troubleshooting friendly print, benchy,
I had to tweak a lot of settings just to get the PETG to print. My printer had a lot of trouble sticking the first layer to the build plate (I am using the default heated metal bed). It also had some trouble with globbing up in certain spots. Once it did stick, I felt that the speed of the print was way too fast, but I let it continue because it was printing alright. As you can see from the print, everything is super jaggy and there is a lot of stringing.
My settings are:
Layer Height - 0.2 mm
Wall Thickness - 0.8 mm
Infill Density - 40% (I can take that down)
Printing Temp - 245 c
Printing Initial Temp - 250 c
Build Plate Temp - 85 c
Flow - 100%
Retraction Distance - 1.5 mm
Retraction Speed - 35 mm/s
Retraction Minimum Travel - 0.8 mm
Print Speed - 35 mm/s
Travel Speed - 80 mm/s
Initial Layer Speed - 10 mm/s
Fan Speed - 50 %
Thank you so much for your help!
I have a part, shown in the 1st pic: 1 large angled face and one small vertical face. There's much more detail in the actual part: this is just a rep.
I want to print it with the large face down on the plate, supporting the smaller vertical face, as shown in pic 2.
The issue I am running into is this: it prints just fine in that orientation, but the support structure on the smaller vertical face does not come off easily, requiring a lot of post-print cleanup. I really need that face to be as clean as possible.
I can print it as shown in pic 1, but it needs a whole lotta support for the interior bosses and cuts (not shown), and I'd like to avoid that: waste of filament.
I've experimented a bit with the Support settings: changed the Z Distance, Z Top Distance, %, but have not yet been successful in getting that mostly clean face.
Can anyone offer up any suggestions so as to reduce the amount of support remnants after the print, making it easier to get clean or be clean after the print?
In order to install a new glass bed mount,I just printed, I'm going to have to replace the bed screws. (The heads are stripped.) Since I have had no luck with local American hardware stores when it comes to finding these parts, can anyone suggest a good source?
