amps for steppers
-
I have and bondtech ddx extruder and it need 0.7 amps just want to make sure
I adjusted it right.
"Due to the fact that the DDX uses a 3:1 gearing ratio and includes a stepper motor that is rated to run at 0.7A, nearly half of the current stock "M906 X800 Y800 Z800 E700 I30
Also when the print ends it backs the filament all the way out. how can I adjust that?
Thanks

if the maximum current is 700ma, you should be setting a value that is roughly 85% of that value. i.e. 595ma (which i think will get rounded up to 600ma)

that would be configured in the slicer normally.

Change your slicer to use relative extruder moves instead of absolute extrusion.

Sorry to hijack this thread, but it is correlated : what is max current given in motors datasheets? RMS or peak? And so, what does 85% represent?
-
@fma 85% of peak
-
To be sure to understand: I have to set the RMS current of the driver to be 85% of peak current of the motor?
And the motors datasheets give peak current per phase? -
@fma that depends on the motor manufacturer for example OMC afaik use peak but LDO use RMS.

Ok, thanks!
