HE3D Delta: Autoleveling Problem

[carlol]

Hello,

I am trying to setup my He3D delta printer and am currently having a problem with autoleveling.

The autoleveling seems to work, but immediately upon completion the extruder proceeds to crash into the heatbed.

Auto level seems fine running G29, but after that, head proceeds to crash into bed, despite 0mm offset.

I tried this with Z_RAISE_AFTER_PROBING = 0 or 10
neither worked. However, when I did autoleveling, my Z values register around 18/19, so next step is I’ll try setting Z_RAISE_AFTER_PROBING to 25 or 30

Results of my autoleveling below:

00:07:16.848 : N18 G29 *11
00:07:36.488 : Bed x: 40.00 y: -40.00 z: 18.51
00:07:38.204 : Bed x: 0.00 y: -40.00 z: 19.43
00:07:39.998 : Bed x: -40.00 y: -40.00 z: 19.77
00:07:41.855 : Bed x: -40.00 y: 0.00 z: 20.41
00:07:43.758 : Bed x: 0.00 y: 0.00 z: 20.02
00:07:45.755 : Bed x: 40.00 y: 0.00 z: 19.00
00:07:47.611 : Bed x: 40.00 y: 40.00 z: 19.24
00:07:49.499 : Bed x: 0.00 y: 40.00 z: 20.08
00:07:51.433 : Bed x: -40.00 y: 40.00 z: 20.52
00:07:51.433 : 21.37 21.03 20.11
00:07:51.433 : 22.01 21.62 20.60
00:07:51.433 : 22.12 21.68 20.84

Any assistance greatly appreciated. Thanks!

Or the alternative changing MANUAL_Z_HOME_POS and vertical print size from 230 to 210.

Hello, I had this problem with my printer before. Maybe your endstops calibration is incorrect, so your height is too long.It stop correctly when you use the auto leveling because it detect the trigger of the z-probe switch.

Changing: MANUAL_Z_HOME_POS to 210 worked.

The heat bed platform increases the height, therefore the home position needed to be adjust. Autolevel now works.
