Issue with SZP on Secondary Idex Toolhead

Superbrain8

Merry Christmas Together,

Ive got around installing a SZP to my idex, since ive got a probe already on the primary toolhead ive got it installed on the Secondary Toolhead.

Got it all configured the probe works too.
My issue is that the Scanning and resulting Mesh is Rotated by 90° i suspect its because the probe is mounted on the U Axis instead X Axis, the mesh is also configured to use the U Axis instead the X Axis.

Running a Duet 3 Mini 5+ with 2 1LC Toolboards and the SZP Sensor
Firmware version for the boards is 3.5.3

Ive noticed that the mesh is off when ive started configuring the probe offsets and mesh size
in the Image Below ive set the Mesh to be larger than the Bed is in the X+ Direction, the Mesh shows its dropping in the Y+ Direction

The Scanning also happens towards the Y Direction instead of X Direction
When running the Mesh Misconfigured with the X axis instead of Y axis the Primary toolhead "Scans" in the X Direction

@Superbrain8 we’ll have to test this to work out if it’s a bug or ‘feature’, but unfortunately we’re unlikely to get to testing until after the New Year. It’s possible this has been fixed in 3.5.4; if you can upgrade and test with that it would be useful, and possibly with the 3.6.0-beta.2 if you’re up for it.

Interestingly, I asked @dc42 a while ago if we could scan with the SZP in the Y direction, rather than X. Scanning in X showed up a fault with my X axis, with a lump every 62mm, which turned out to be a flat spot on one of the wheels of the X axis.

It would be interesting to do the same in Y. Sounds like you might have found a workaround to do that!

Superbrain8

@droftarts will try to update to 3.6

dont think this will fix the issue you have there, the entire mesh is quite likely applied at the roated state making it not really usefull.

also yea im patient its holiday season so what is a week or two

Superbrain8

Updating to 3.5.4 did not Fixed the issue, will try 3.6.0-Beta 2 next

Superbrain8

updating to 3.6.0 kinda borked the entire machine, have to dig into that first.
cant home after the update

Homing resets the wifi module?

droftarts

@Superbrain8 Okay, sorry about that!

While there are a lot of changes between 3.5 and 3.6, the configs are generally unchanged. I can’t see anything obvious in you config.g, but I’m on my phone at the moment, so easy to miss things. Best to revert for now and I’ll test in the New Year.

Ian

Superbrain8

@droftarts is there any update on this?

T3P3Tony

@Superbrain8 have you tried with 3.6beta4. If not please do so and see if the issue is still present.

Superbrain8

@T3P3Tony 3.6beta4 still causes the same issue ive had with beta 2.
the Z axis no longer homes and resets the Wifi module

M122 did not show anything suspicous

Was the software reset this message applies to the reset 1min 20s before you ran the report? (i.e. did you run that M122 at 15:37 approx today?

When you says it resets the wifi to home the machine, does it actually reset the entire board (i.e. the symptom of DWC disconnecting is actually the board resetting)?

Does this happen everytime you home the machine?

Please attach your homing files.

the issue is not present on 3.5.3

the printer has 2 endstops mounted on Z low to level the gantry when homing

T3P3Tony

@Superbrain8

To confirm you have rolled back to 3.5.3 and the same homing file works? Does it work in 3.5.4?

Also please confirm these:

Was the software reset this message applies to the reset 1min 20s before you ran the report? (i.e. did you run that M122 at 15:37 approx today?

When you says it resets the wifi to home the machine, does it actually reset the entire board (i.e. the symptom of DWC disconnecting is actually the board resetting)?

Does this happen everytime you home the machine?

Superbrain8

the heattaskstuck error where from updating the firmware.
the software reset where from the homing yea.
rolling back to 3.5.4 keeps the homing in working condition

T3P3Tony

@Superbrain8 thanks. also:

When you says it resets the wifi to home the machine, does it actually reset the entire board (i.e. the symptom of DWC disconnecting is actually the board resetting)?

Does this happen everytime you home the machine?

Superbrain8

homing the machine causes it to get stuck when attempting to home the Z axis it times out and the wifi module seems to reset, that is atleast what i can see on the panel due that reconnects to the Wifi on timeout

T3P3Tony

@Superbrain8 ok interesting. can you run it a couple of times on 3.6.0beta4 and post the M122 after each one. I am looking to see if the error is identical.

T3P3Tony

@Superbrain8 also please send a picture of the paneldue console when this happens for me to double check.

Superbrain8

Homed 3 times and ran M122 after each unsuccessful home

@Superbrain8

It looks like from the M122 that the whole board is resetting on homing

Here is an experimental build that it would be good to test please.
Duet3Firmware_Mini5plus.uf2

It is an internal build to fix a different issue but that also presented as a heattaskstuck so they may be related,,
