Hi, thanks for helping me.
This is all that is in the BL Touch Retract file:

M402

If I just enter M402 on the command line, a "probe" error is raised.

Best regards,

Hans ter Hart

@Phaedrux Next to my previous remark: This is exact error text that is generated:

M98 P"0:/macros/BLTouch Retract"
Error: Bad command: probe

There is no error on the deploy macro.
Also, if I initiate the command "M280!P0 S90" or "M280!P0 S10" the BLTouch deploys and retract without an error.
The error only comes on M402.

Thanks.

@Phaedrux Yes, I did. But unfortunately it didnt solve anything. Error stays.
Thanks for your help.

Here is the homez file:

Hi,
the (original Antclaps)BLTouch sensor on my printer is giving problems.
When I use the G28 command or home the Z direction, I get the error: G28 Z Error: Bad command: probe
I tried to find the reason for the error, tried different versions of the firmware, nothing works really. The error stays.
When I use the command M280 P0 S10 / M280 P0 S90 no error occurs.
Using M401 P0 and M402 P0 give an error.

Does anybody have an idea of what I'm doing wrong here?
Thanks a lot for your help.

I tried other (newer) versions but that makes no difference, error stays)

Oops........Sorry!! That did it. Case solved
Thanks!!!

After installing 3.3RC1 and after G29 no height map is shown. Message "Invalid height map" is shown instead.
Deleting the height map and generating a new one via G29 brings up the same error.
Does somebody have a fix for that?
