slowmo since extruder upgrade

[funkydrgonzo 0]

hi

UM original (without plus) extruder upgrade to bondtech QR failed. After upgrading we added the settings into the start-gcode section in cura, everything started working in slowmo. Means that the head moves around 1mm/min.

Unfortunately the same with Z and E :-(

Of course we went back to the original extruder but, well, the slowmo problem still appears.

What we tried yet:

- flashed the fw about 5 times with the original one coming from cura 1.5

- removed ulticontroller and tried printing over usb

Sadly nothing helped out. Any ideas if we f.... up the controller ?

thx

Somebody else needs to pitch in as I really don't know about the UMO, but on the UM2 the e-steps stay the same if you flash to a new firmware, except when you do a factory reset. So my guess is you messed up the e-steps settings, but you should be easily be able to change them back (again by g-code). On the UM2 is easy, you just do it by using tinkergnomes firmeware.

Anybody able to tell the correct UMO esteps?

Inthink it should be Control / Motion / (scroll down) Change esteps -> Back to control / Store settings

but what should the esteps be on UMO, he probably can't see anymore if its messed up..

He can do a restore factory settings, I don't remember the name of the option...

Anyway always back to source, on github marlin for the original says:

#define DEFAULT_AXIS_STEPS_PER_UNIT {78.7402,78.7402,200.0*8/3,760*1.1} // default steps per unit for Ultimaker

So 78.7402 for x/y 200.0 * 8?? For z (weird number...) and 760*1.1 for esteps
