And now I have no Z movement from my LCD… I’ve checked the driver by swapping it to the Y and I’ve checked the stepper by swapping it over to the X driver and all is good but regardless of what I do I have nothing on the Z…
Like I said something simple I’ve missed probably…
Strange. So version 414 would move the Z axis? Did you check this just before you updated the firmware? So to be clear, when you tested the Z stepper by swapping it to X, you made that swap at the control board so that you tested the wire and the stepper? Also this is not an update from an old version of the MPCNC that used threaded rod instead of a lead screw is it?
The next thing I would do is to reinstall version 414 and see if that fixes the problem. If it does, then you can use a difference tool to look at the differences in configuration.h and configuration_adv.h for both versions. There is still access to some of the older versions of the firmware. @vicious1 mentioned them when working with another forum post, but I don’t remember where they were.
If it doesn’t fix the problem, you probably have an issue with the board…probably a pin on the MEGA board, but that is only a guess.
With 414 all axis worked fine - but that was probably 6-8 months ago when the build stalled, since then the Mega and RAMPS boards have physically moved mounting position but they are the same boards, same wiring etc.
When I say I swapped the Z motor to the X drive, yes it was changed at the RAMPS board so it test the wiring and the motor.
I’ve only ever used a lead screw on this build.
I like you idea of rolling it back to 414 to confirm it works - or not - I should have the old 414 build on my PC still.
I also have another MEGA board too that I could swap over to and test that too.
