Auto Bed Levelling issues

[Daftlander]

Hi all. 

 

I've bought my Ender 3 a Bigtree SKR mini e3 1.2 board. After tearing my hair out trying to get firmware to work on it. I finally have it working. But now my BLtouch is misbehaving. When I auto-home it doesn't do the z homing in the centre as it should. Then when it does the bed levelling sequence it goes right to 0,0 and the BLTouch misses the bed entirely. 

 

I have set the offset on my probe properly and I have Z_SAFE_HOMING enabled. I'm at a bit of a loss here. 

 

Any help is greatly appreciated.

Post your firmware -- but if you're correct in that you offset the probe properly this wouldnt be an issue. Start from the beginning with the TH3D firmware and try again?

Apologies for not coming back to this. But I figured out the issue. 

 

The changes I made in config.h were not being made in the firmware file when I rebuilt it. I cannot for the life of me figure out why. 

 

In the end I changed the probe offsets via pronterface and now the printer is back up and running.

 

Eventually I will try and figure out why visual studio is being such a bastard, but until then I have somewhat resolved this issue. 

 

Thanks ColinLTT for trying to help.
