Hi,
i am using a Rumba Board with the Marlin Firmware.
When i started building my Printer i still thought it would be sufficient to use threaded rods from the hardware store for the Z-axis.
But i never get a really clean Print (a wavy pattern on the sides of the object). You could even see the whole X-Carrier wobbling back and force.
Thus i exchanged the standard threaded rods with industrial grade trapezoid spindles. Now the whole thing is very stable,
and i am happy with the outcome, however the angle of the threads are different, and i need to recalibrate the Z-axis.
Somehow i lost the Firmware files i edited, so i have to start from square one.
So finally the Question:
Is it possible to recover the calibrated values somehow (over the console maybe).
Mainly the steps per unit for the extruder.
Thank you in advance
