BambuLab P1P with textured plate & PETG settings

[GrouchoDuke]

Hey everyone,

Does anyone have good settings or tips they could share for getting PETG to stick on a P1P or X1 with a textured build plate? I haven't been able to get a print to stick yet with Simplify3D, but it's working fine with Bambu Studio.

I've been using S3D for quite a while, but just recently updated to v5 because I'd love to use it with my P1P printers. I tried several prints with the stock "Bambu Lab P1P" profile and then adjusted the PETG auto-configure settings to match the temps & fan settings I was already getting great results with BambuStudio. I tried a few prints, but they popped off during the print.

I know that BambuStudio introduces a Z offset that varies depending on what plate you use. Digging through S3D's gcode, I didn't see anything that mirrored that. So, I added G29.1 Z-0.04 to the Starting script in S3D and also tried -0.08 (Bambu Studio uses G29.1 Z-0.04 for the textured plate Z offset). Neither seemed to make any difference though. It's possible I added it at the wrong place.

I could certainly start doing global Z offsets until I find the happy spot, but I was hoping someone has the perfect solution already figured out.

Anyone figure this out yet?

Thanks!

Using a small global Z-axis offset is a good idea. Start with something like -0.05mm and slowly increase until you find a good position.

Sometimes you also just need to slow down the first layer print speed. You can set an absolute first layer speed on the Layer tab which can help if you are normally printing at really high speeds.

Yeah, I guess I'll start down the z-offset path. The stock profile already had speed set to 25mm/s, which is slower than I print from Bambu Studio.
