I wonder if anyone can shed some light on my (latest) issue.
Y, Z and E are all fine. They go home, they travel CW and CCW when asked. They do appear to be behaving as if they have a short max-min distance, but I've not set any step sizes etc, so I guess thats not too suprising.
X on the other hand is being weird.
Clicking home in Repetier Host makes it move towards the end stop about 3 mm. sending it + or - generally does nothing. Ocassionally it moves a few mm but I don't know what causes it to free suddenly. Its also ignoring the endstop (if I manually press it and press home it still moves about 3mm).
I've switched stepper drivers, and swapped the X & Y motors and see the same behaviour, so I think its firmware related.
What else can I check? Any suggestions for fixes?
