Can anyone help set up a dual y axis on a creality v4.2.7 board?

hi everyone. i would like to ask if anyone has setup dual y axis motor on this board? most of the examples on intrnet are boards with dual extruder outputs on the board and are using e1 as the Y2. On the creality v4.2.7 it only has 4 total motor outputs. im going to use this board to make an etching laser and i would like to have dual y axis motors because of the length of the bed to drive the gantry. i dont need E0 or Z outputs on boards but i would like to use the Z axis output as Y2 axis output. has anyone ever tried this?? im using marlin firmware 2.0.9.5
thank you for reading this.

Hey Jerry :wave:

I haven’t set up that creality board but I just finished tweaking configs for a non-v1-standard SKR board so it’s still kinda fresh for me.

Have you tried setting EXTRUDERS to 0 (ie #define EXTRUDERS 0)?

You may also have to set Y2_DRIVER_TYPE. And there are a few places you’ll have to modify to have 3 values for X,Y,Z instead of the 4 configured defaults for X,Y,Z,E (but the compiler should tell you where those locations are)
