Help needed for axi movement SKR 1.4 turbo
June 30, 2020 05:32PM
Hello there i need some help

I designed my own printer and it requires 2 Y axis and 2 Z, since there are 2 Z connectors there are no problems there. But with 2 Y's I would like to copy the movement from the Y axi connector to the E1, but i'm really not sure how to do it correctly. I know i can probably solder wires together but if i can do it with software I would rather go that route with seperate driver
Thanks in forward smiling smiley

Sockets ZMA and ZMB are both controlled from the 1 z stepper driver. This requires no special firmware settings. This works fine for a lot of cases.

Sockets YM and E1M have their own stepper driver, so this requires firmware to work.

Presuming Marlin firmware.

In Configuration_adv.h you will find the setting Y_DUAL_STEPPER_DRIVERS, enable this
If you have EXTRUDERS 1 in your Configuration.h it will automatically use the unallocated E1 stepper driver for Y2
Make sure to set Y2_DRIVER_TYPE and not E1_DRIVER_TYPE in Configuration.h
