6XD+1LC+RC3 Bltouch throws random error mode

Aurimas

So the system was running no problem at all.
Installed RC3 firmware and it started - the BLTouch would go into error mode randomly while probing the bed.
Tried different probing speed, different height, different sebsitivity - nothing helped.
Finally went back to RC2 and all issues are gone.

Can you share your homing files and config?

Aurimas

@Phaedrux - what does homing file have to do with this?
RC2 - works no issues at all
ungraded to RC3 - probes random amount of points and then throws an error
went back to RC2 - works as expected - not a single error

NO chnages in the config/homing or anything else have been made. ONLY firmware upgraded and downgaded.

Config is below - but you will not find anything in there because it works with RC2
And yes different G31 pxxx values have been tsted. from 200 to 1000 and made no difference on RC3.
On RC2 anything works

what does homing file have to do with this?

Probing when doing what? You don't specify.

G32 or G29.
it can throw an error after 2, 5 or 10 probed points.
the fact is that it works with RC2 but fails with RC3

T3P3Tony

@Aurimas we have been discussing how the BL touch goes into error mode. This could be an issue with the probe deploy and retract files, please could you share those.

And also bed.g file please.

unless it is something different in RC3 from RC2 I cannot see how it could effect anything.
on top of that - it is working, but no the whole way.

I have also replaced BLTouch a couple of time just to make sure - nothing changed.

File attached - just rename it to .zip

Those bed and probe files are extremely basic. Definitely not the issue.

Thanks, posting here to make it easier.

Do you have a mesh.g ? If so please post that.

Can you confirm that when you say going into error mode, please describe this.

Probes keeps going around and probes the points.
At random stage it would hesitate to respond to the touch and goes into error mode.
starts blinking and duet reports that probe was trigered before probing.
I could not finish single G29 on RC3
back on RC2 didn't have a single issue so far

gtrider

@Aurimas And chance you are seeing an "invalid Z probe index" error too? Before I updated Duet3Firmware_TOOL1LC.bin and the other files several times I was getting that error. I went to the line number it gave and nothing was wrong with the g31 command. Resent all the RC3 files over one at a time again and rebooted again and all was well.

Aurimas

@gtrider - no errors. nothing to do with it

gtrider

@Aurimas Yours was the only BLtouch related posting I saw on RC3 . Mine seems to probe OK, I tried it twice and a G32 just in case and they work fine. . Had that error at first and went looking to see if something changed in the config.
