Z motor on expansion board not moving

jay_s_uk

@wdenker duex5 IOs are inverted as standard I believe so you'll probably have to add a ! To the pin name

@jay_s_uk your right I did have to add the ! but doesn't solve my duet 3 problem which after more testing I think is interferance or cable length.

@wdenker sorry, should have spotted this earlier:

Filament monitors must be connected to the same board as the corresponding extruder motor. This use so that the firmware can correlate the measured filament movement and the commanded extruder movement in real time.

See https://docs.duet3d.com/User_manual/RepRapFirmware/CAN_limitations#permanent-limitations

You have the extruder drive on the mainboard but the filament monitor on the 3HC. Move the filament monitor to the main board, or the extruder to

@droftarts It is not on the expansion board I don't know where you're seeing that.

@wdenker sorry, I was looking at your config.g you posted earlier, and I could have sworn it said the extruder drive was on 0.0 and the filament sensor was on 1.out1.in!

Could you post your current config.g, in case anything has changed?
