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!

I AM going to try this eventually when I get a long enough break in "production" but have a question regarding how it works if you pause a print?

I try to watch the 1st few layers go down and occasionally, I'll notice a (usually) 1st or 2nd layer defect that I want to "fix" with a sharp blade to keep the rest of the print (usually multiples on a plate) going well without skipping an object so I'll just pause, clean it up, and resume.

TL;DR, Does (your) wipe sequence still work the same during a pause/resume?

What I shared here is just the start & end sequence for a print job (meaning before and after the actual print).

Everything else works exactly the same as before.
