Hi,
every time I feel I have set up the BL Touch complete some thing happens. You would consider the printer has a virus.

Last night everything was working and I only had to set the Z off set, so I decided to do that the next day.

Next morning the printer will not auto home correctly. At first it would hit the end stop for x and Y then mover off the bed to y 200+ the z axis did not move.

I reloaded the firmware no difference then a Restore Fail Safe stoped the x y crashing off the bed.

Now x and y home at 00 and Z tries to home but off the bed instead of at x99 y148 which is displayed on the screen.

Can I adjust the firmware for this?
Is there a factory rest that clears all setting and then reload the firmware?

Any help would be appricated.

Robert

Hi Robert,

Yes the offsets are set in the configuration.h. You would have to look X_MIN_POS/Y_MIN_POS and/or X_MAX_POS/Y_MAX_POS the variables are self descriptive. The MAX POS is usually set to the size of your BED.

A few things I would suggest for you to check

Are the END Stops connected correctly and is there anything blocking them ?
What is the BED size set in the firmware ?
What is the BED Size set in your slicer software ?
Is the configuration.h set to use EEPROM ? If so, is there a conflict i the values stored in the EEPROM vs the firmware.

Please share your results if you resolve this.

Thanks for the help. All fixed now.
