1.11 to 1.21 on Ormerod 2, X home only moves 5mm and zeros
-
So It's been a while since I upgraded the firmware on my Ormerod 2, and I'd thought I'd give it a go this weekend since I had some time.
As far as I can tell everything went well, I was able to use the new PID tuning.My problem is this, I can't get the X axis to home properly. (I did read the notes and added the S2 flag to the Z axis movements. but I'm still getting strange behavior, when I home X I get the following:
- Z axis moves Up
- X axis moves negative ~5mm
- X axis sets current position to x=0mm
- Z axis moves down
When I home All I get this behavior:
- Z axis Moves Up
- X axis moves negative ~5mm, and Y axis goes until it hits the homing switch
- Y Axis moves back and hit homing switch again
- X & Y zero
- Z Moves down
I checked the HomeX & HomeAll files in the GitHub and I don't see anything different from mine (FYI the S2 flag is missing in the GitHub files). I also looked at the config file in the GitHub and didn't see any obvious differences there.
I've confirmed that the Z probe is working correctly in the web interface, it's reading 0 the whole time the home operation runs - I also tried inverting it so it read 1000 the whole time; and the homing behavior was the same. FYI I'm using the DC42 smart probe (small version)
I assume I've missed something stupid and obvious, can't wait to find out what
