Z safe homing not working #351

Open Rockefella95 opened 4 years ago

Rockefella95 commented 4 years ago

Good morning,

i've made a new Marlin 2.0.5.3 Firmware for my Ender 3 and got a problem with the homing where i cant get into it.

Bigtreetech SKR 1.4 Turbo TMC 2209 BL Touch

I got sensorless homing set up for X and Y. Now i also got the BL Touch working with a small edit on the Pins file. The problem is now that the printhead is not driven to the middle of the bed to home Z there.

Maybe i found the failure because i had setup Y min and Y max Endstops. When i disable one of these its driving to the middle of the bed but when i configure it like that the BL Touch stops working.

When i go back and enable both Endstops again then it goes down on X0 Y0 but i can stop the Movement of the Axis by triggering the BLTouch by hand.

Did someone got the same problem or can help me somehow please?

Hi.

It appears that you have “//#define BLTOUCH” present in your ‘configuration.h’ file. If set up correctly, this should be un-commented to “#define BLTOUCH”.

This along with mentioning modifying the Pins file, which should not be necessary, makes me think that you have not correctly configured your settings.

I do not have this particular board yet, so can’t give you a known good configuration. My suggestion would be to search for a sample Marlin 2.0 configured with a BL-Touch and try to make the same changes to your configuration.

Good luck with this. Persevere and you will get it working.
