SOLVED. extruder working in X | Y | Z but VERY slow in XY and chattering

Hi folks,
I discovered something weird in the startup in console on Pronterface.
Pronterface displayed a "M92 x80 y80 z4000 etc" inspite of the firmware
having been changed and installed multiple times with different settings in
configuration.h.

It took 3 M502s in a row in the console to get the EEPROM to revert to default settings
and the settings from configuration.h

I'm assuming there were other incorrect settings lurking that caused the stepper issues
as soon as the above was done, everything lined up.

Why this happened? I don't know, maybe flaky hardware, maybe flaky user.


Many thanks,
Andrew

Okay,
definitely a case of user=ID10T

I hadn't realised that M92 had been written without realising it sometime this week
to EEPROM. Of course I had EEPROM turned on as I was playing with Z Offsets.
Kind of explains why none of the changes to the firmware worked.
