Thanks for tip - about to order.

I have a really strange issue, using latest 3.4.6 firmware, mini 5 and ender 3 with dual z steppers, bl-touch.

I have been able to tune the microsteps in Y, Z and E with success. However no adjustment I make in the M92 X command makes any difference.

Have used M92 to report the microsteps and it shows what I have put in as the calculated adjustment, (the one that successfully calibrated the other 4 steppers), but every test print comes out with a 2% undersize in the test print.

I have tried ridiculous over and understep adjustments but they make no difference, the test build X build remains at 2% under the target.

It's driving me insane, can anyone suggest what I may have missed. (Have checked all the home?.g files for overrides but cannot see any issue. I know that the bed sizes are incorrect for an Ender 3, they are there to try and force additional probe, the slicer is correctly setup for the printable area etc.

Thanks for tip - about to order.

@dc42 thanks - will give it a go, have hot air station.

@dc42 so you use it in the AT mode, you have no special code running on the ESP? If so I will buy a couple off Amazon. Worked for Intel for 35 years, so, not afraid of surface mount!

@chrishamm test of memory, 2 years?

@chrishamm

is this ok - board is still in my ender 3

@chrishamm thanks Chris - looks like it is knackered! Tried complete firmware update, 3.4.5 and reinstall of wifi too - no change.

Can I assume that my Duet 2 WiFi, wifi module, has failed given the following when a M122
command is sent. It all worked about 2 months ago, nothing changed, and, YES I have gone through the routines of setting wifi up using M552 AND M587 commands....
So, if I am correct in assuming the ESP module is knackered, can I get it repaired? Replace the module?

M122 section on wifi was as follows.

= WiFi =
Network state is changingMode
WiFi module is idle
Failed messages: pending 0, notready 0, noresp 0
Failed to get WiFi status
Socket states: 0 0 0 0 0 0 0 0
