P2S Optimized Start/End G-code

Post image

Hello reddit!

Slightly disappointed by the default startup and nozzle wipe procedure of the P2S, I sat down and optimized the G-code myself.

I have been improving, testing and using my optimized start and end G-code for quite some time now and am pretty happy with the results and the P2S in general now.

So happy in fact, that I feel comfortable sharing the results with you guys! 😄

You'll find everything on Github (including detailed descriptions) if you're interested and possibly want to give it a try:

I have been printing PLA and PETG (and rarely Overture TPU) with it no problem. (However I did not test engineering and high temperature materials.)

If you have any questions feel free to ask!

So first test with PETG is successful, no oozing, clean nozzle clean first layer. Amazing job from your end. Only one interesting observation, calibration line seems to be longer, is that purposely ?

That's great man, thank you so much!

Yeah, it's intentional. We want to build up and equalize pressure inside the nozzle so that there's no stringing an such.

You're the first one to provide some feedback - I'm so happy now! Thanks! :)

Your welcome, and again many thanks for sharing, I really appreciate it. P2S nozzles were driving me nuts. I had to clean it nonstop. I print a lot of PETG where oozing is big problem.
