Is there a way to get current “steps-per-mm” for the extruder?

One way is to send M501(= Read parameters from EEPROM) and parse the responce.

M92 sets the Steps like:

M92 X87.489 Y87.489 Z87.489; Set X Y and Z steps per mm
M92 E420; Set first extruder steps per mm
M92 E420:430; Set both extruders

What I search for is somting like
M92; Get the steps-per-mm
Responce:
X87.489 Y87.489 Z87.489 E420:430
OK

I’m not sure if you’re asking a question or giving a guide…

I think he wants the M92 command to output the current steps per mm…
