Probing speed tied to X position
-
@Matej101 what is also important is the homeall file, please post it.
While your printer probes, please make a M122 and post this also. This is a reporting tool and if there are serious errors, M122 will show it.
The general recommendation is to use RRF 3.1.1, because it fixes some problems since 3.01 RC12.
You have a lot of specific M569 settings for the steppers. To exclude them from a possible reason, you can try removing the specific settings for a test whether the strange behaviour still happen. Is there a reason for using this specific parameters?
I don't understand the S2 parameter in bed:
G30 P2 X225 Y95.5 Z-99999 S2
I cannot find documentation for it, I would remove it. And the X coordinate may be outside or very near the edge of the bed for the probe, because 225 + G31 X offset of 23 is near the M208 X upper limit. If this point is where the probe is fast, I suspect it is fast because the probing doesn't work at this point. But please test removing S2 and setting X a bit lower to test this theory.I found a thread about Prinda: https://forum.duet3d.com/topic/13219/rrf-support-for-pinda-probe/3 it mentions temparature correction in G31, but I don't understand this comment, but maybe you know what to configure.

video of the issue: https://photos.app.goo.gl/X2tRCxf1cV6RoKR86
the individual probe moves in bed.g are for gantry levelling (my z axis has two steppers with leadscrews connected to independent drivers). I thought the S2 parameter was for applying the levelling, I found it on the dozuki.
my probe is the v1 PINDA, later revisions have a built in thermistor for temperature conpensation.
-
both firmware and dwc should be on 3.1.1
-
@Matej101 On you video I see only one move down at the right position, is this correct? (video ends after moving one time down).
Can you please tell me the link where you found S2, I cannot find it.
-
@JoergS5 no, on my side the video show the entire bed probing process (probe left side, center, right side of the bed, than apply bed tilt correction, than probe the bed on a 5x5 grid)
I found the S2 here: https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors

Well...
I just started a print and the issue just isn't there. What? Why? I don't understand... -
@Matej101 funny!
Thanks for the link, I was not aware of the S2 parameter, it is not mentioned in the common G-Code page. I can see the whole video now also, I made the mistake of viewing the preview only...
So it's working now? Don't change anything now... (serious: make a backup and if it reappears after changes, compare the configuration). Maybe it was the update to 3.1.1
-
The thing is, I didn't change anything. I just turned the printer off, went outside for a few hours, returned, turned on the printer and pressed print. Issue gone.
-
I was already at 3.1.1
-
@Matej101 I expect it will appear again, if you didn't find any reason. Maybe a loose connection or a thermal effect. Please tell if it reappears. And if it reappears, you should make a M122 directly after appearing, maybe you can analyze something then.
