RAMPS 1.4 Extruders / dual axis motors #4

Hi, is it possible to configure the RAMPS 1.4 with your firmware to duplicate the output of motor X to E0 and motor Y to E1? Just like on Marlin / Repetier firmware - #define Y_DUAL_STEPPER_DRIVERS

CarlosGS commented 7 years ago

Hi, this is not implemented, but it should be easy to do so:

First add the definitions for Y2_STEP_PIN, Y2_ENABLE_PIN, Y2_DIR_PIN in https://github.com/CarlosGS/grblForCyclone/blob/grblForCyclone/cpu_map.h#L372
Then you will have to modify each function in ramps.h, to duplicate each call that affects the Y axis. Cheers, Carlos

could you make the entire example please, im really not used to write definitions.

i would love to have a cloned y axis.

also how to modify the ramps.h

thanks

Hi, sorry I don't have the time :( Cloning an axis can also be implemented by physically connecting both motors to the same driver, or even by wiring two drivers in parallel (each driving a different motor). Cheers!

thx, i'll try that
