You know what I don't think it is the bed level now, he should be seeing the zprobe scrape on the plate and he'd already know there was an issue there (ie the effector is not flat when extended to all edges of the build plate - if the effector tilts at all, this will cause this) but as I said he should have noticed that.
If one or more of his arms are even slightly out of length, when the head moves around, it will actually tilt the end effector off the horizontal axis, therefore tilting the nozzle when it gets to the outer edges of the plate.
On the firmware I used for my delta, the zprobe is automatically enabled, and even if the endstop is not there to tell it it hit the bed, it will still generate what it thinks is a safe set of G29 coordinates, it just does it a fair bit away from the plate thats all (instead of actually probing the plate and getting a genuine set of coordinates)
As far as that problem he has, im a bit baffled now, i'll see if I can mess my machine up and replicate it..
Please explain to me how to...
