Reformatted old SD.

Do you have a fresh sd card to try?

Can you send M98 P"config.g" and report the results?

Ethelred

SD on the way - What would one do without Amazon ?

I'm in the dark as to "open file count", it's impact , and what to and how to mitigate it.

Can you post your config-override.g?

Ethelred

@Phaedrux
Config-overide. Sorry to be so unresponsive but what with cleaning out and moving house priorities get confused. Hopefully new SD tomorrow.

yes I'm curious to see if it makes a difference.

Also, can you please post your tool change files if they exist?

tpre0.g tpost0.g

Can you upload the actual files as well for config.g, config-override.g, tool change files, etc?

Ethelred

@Phaedrux New, fast, big SD same behavior. No tpre0.g tpost0.g files.

I'm thinking a controller board glitch. Initial fail followed a perfect print with NO changes whatsoever. My problem (one of many) is that I'm electronically and software challenged. I'm tempted to buy a new board or take up golf.

config.g config-override.g

Can you give a run down of the issues you're currently seeing?

Ethelred

Same as original post.. To recap
The printer homes normally. Don't know if thehoming offset leaves the nozzle in the correct location (no way to measure that). If, for example I command a simple G1 X100 the nozzle scoots away in an approximately 45 deg angle for perhaps 80-100mm and the Z ht looks to drop perhaps 20mm. If I reverse with a G1 X-100 it appears to return to the original position. Crazy.

@Ethelred Because you have M501 at the end of your config.g, it's loading config-override.g:

I think this bit must be causing problems:
M665 ... Z279.000

That's just wrong! It should be around zero, like the X and Y. Maybe calibration went wrong, and it's saved that. Try setting it to Z0, and/or redo the delta calibration and save it with M500, and see if it behaves after that.

Not so - M665H is the homing height distance from the bed in the case of a Delta printer.
Does no one think it just might be the Duet electronics? Are you monitoring this Mr. Crocker?

@Ethelred I didn't say M665 H, I said Z! M665 Z is

Znnn Z tower position correction

See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m665-set-delta-configuration

Definitely wrong!
