Thanks DC42. My delta radius was out quite a bit.

Just finished assembling my Kossel XL from Think3dPrint3d with the Duet WiFi. Every thing was going fine up until I sent the G32 command to calibrate the bed. The hot end crashed into the glass bed( at least it did not crack or break), at first I thought the IR probe had not triggered but it had. I spent several hours trying different configuration settings etc but nothing helped it keeps running into the glass. What I eventually observed was that as the effector moves out from X0 Y0 the Z Height drops (the readout shows that the z height has not moved). at a distance of 100mm from the centre it will drop somewhere between 5 and 10 mm. This drop appears to be uniform no matter which direction I move from the centre (at first thought the bed was badly off square.

Has anybody else had this problem or any idea of what I need to do to correct it?

Regards,
Tony
