G29.1: Set Z probe head offset
Set the offset of the Z probe head. The offset will be subtracted from all probe moves.
So it looks like you simply changed the probe offset by .03.
Seems like a change you shouldn’t have to do. IMO, that would suggest another problem is the real culprit and this is a workable band aid.
Well now Im confused even more…
I ran a print with Bambu ASA profile- using the G29.1 (0.03) change mentioned, and it ran 6 of my test parts great.
Great, right?
I ran the same print of 6 without the G29 change to confirm, and that print crashed.
I ran again with the G29.1 changed to 0.03, and it crashed again???
I’ve opened up a support ticket, keep you guys posted.
Meanwhile, the original Bambu ABS filament should be arriving soon, so I’ll give that a go.
I’m still not getting any form of consistent results, which pisses me off for a printer this expensive.
Likely your print speeds are too high
I print ABS and ASA often and my speeds all around are substantially lower than the preset values
So, your suggesting the Bambu filament settings for ASA and ABS are too fast and cause the printers to crash?
Its a reach, I’m all for it if it works however.
What speeds in mm/s do you run ASA?
I’m working right now but when I get home I’ll post up my settings (slicer and filament) if you like
That would be fantastic.
Another helpful bit of info would be- what is your failure mode if your speed IS too high?
Do you get XY lost steps and total spaghetti failures?
That is exactly what was happening
At the time the firmware (I don’t recall the version but it was over a year ago) would park my nozzle in the front right corner due to lost steps
And the spaghetti was more than I could eat at my favorite Italian restaurant
I couldn’t figure out what was happening and was under the impression that the firmware was causing the issues
Turned out I was just trying to print too fast
It’s difficult not to try and print at breakneck speeds because we are sold on these printers having high speeds with high quality so of course we want fast prints that look perfect
Even though I slowed my speeds down it is still printing plenty fast, for some readon that took a while to get used to
Tried doing a 50% of every speed setting, still started hitting the nozzle and got loss steps recovery kick in.
Interesting.
I haven’t edited the slicer speeds, but Ive done my testing in standard mode.
I did notice it seems like all filaments have the same speeds by default. I updated to 1.9 studio today at work and checked, the speeds were the same.
FYI, Stealthburner (and all official Voron parts) are designed to not need added supports, occasionally they will be designed in to the STL.
I have just been printing some ABS parts and once it gets to about 70mm I get the rubbing sound, that’s at 0.20 layer height, if I print at 0.08mm layer height I get the rubbing sound on layer 2, all the prints completed though.
This does not happen with any of my other printers when printing ABS and they all sliced on Orca.
This needs to be forwarded to Bambu Lab
Does not really matter much. I threw it in the bin since it was to show that it printed without a spaghetti problem.
So, today I tried with Bambu filament.
It’s official. I can’t print ABS with this printer.
So still no response from Bambu support. Trying my luck with the manual tuning block from the wiki.
This is Bambu lab ABS after tuning PA.
Do you preheat the chamber for 20-30 minutes before printing and do you make sure to not open the door at all during printing? Is the room your printer is in cold?
The room is fairly hot, 25-26 degrees Celsius, and the printer has been warmed up.
I’m used to printing ABS on my Voron.
Do you ever use cleaning filament when switching back and forth between ABS and other plastics?
No, never tried that. Did use a new, never used nozzle for testing.
Just ordered an X1C and going through the posts any updates on this?
