Homing Issues

piankoc

After a few busy weeks of not using my printer, I went to work on another new print and after ironing out the wifi connection issues and upgrading to 3.4.5 from 3.4, I am running into an issue during homing

My homeall script is below
G91 ; relative positioning
G1 H2 Z5 F8000 ; lift Z relative to current position
G1 H1 X365 Y365 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
G91
G1 H2 X-5 Y-5 F6000 ; go back a few mm
G1 H1 X365 Y365 F360 ; move slowly to X and Y axis endstops once more (second pass)
G90 ; absolute positioning
G1 X225.5 Y178.5 F8000 ; move probe to center of bed and home Z
G30 ; home Z by probing the bed
G1 X180 Y180 F6000 ; Move nozzel to center

It looks like after the first pass for X and Y it leaves relative positioning (that's why I added another G91) and goes to absolute coords x=-5 and y=-5

Then takes forever to move slowly across the entire build plate to do the second pass. Once completed there the Z probe (BL Touch) hits on the first pass then never does the probing move...

Not sure where to go or why this all of a sudden no longer works after it worked fine in the past... Any help would be greatly appreciated

Can you upload the homeall.g file itself so we can take a look at the actual file?

Can you duplicate the problem by sending the commands from the file one at a time in the console?

Does G28 X and G28 Y work correctly on their own?

Has anything else changed recently?

Do the endstops report their status correctly with M119?

Can you share your full config.g and the results of sending M122 and M98 P"config.g" please?

piankoc

@Phaedrux config (1).g homeall (1).g
see homeall and config files above.

This still happens when sent from the console or with G28 X and G28 Y individually

Nothing else has changed recently. The last print was successful a few weeks ago and it has sat dormant since then.

M119 returns correctly
Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: not stopped ----- when all switchs are open
Endstops - X: at max stop, Y: at max stop, Z: not stopped, Z probe: not stopped ---- when X and Y are taped down

M122 Output:
M122

That seems quite strange and I can't see anything that would cause that to happen from your files.

Just to try and exorcise the ghosts, maybe try uploading the firmware zip file again and maybe rename your homeall.g and generate a new one from scratch.

@Phaedrux
So good news and maybe bad news with it. I redid the homing files and tried uploading the 3.4.5 firmware again. That did not fix anything.

But I thought I would try downgrading back to 3.4.1 and the issue is now no longer there...

Planning to now upload each new release until it starts again. At least then we could figure out which update caused the issue...

dc42

@piankoc thanks, let me know when you have established the version at which the problem first occurs.

piankoc

@dc42 Works fine up to 3.4.4 and breaks again on the update to 3.4.5

dc42

@piankoc, thanks.

@piankoc this has been resolved. Please see https://forum.duet3d.com/post/302699.
