Bug with Enable Pin set to "Enable before each print"

Hi,
when i set the above option, then no matter what i do in Z axis control, the motor always moves down. At least it started doing so when i started a print and ran into my hard stop at the build plate. I couldn't move it up anymore.

I set it to "Ënable on boot" and it works normally again.

This is what the log says:

Re: Bug with Enable Pin set to "Enable before each print"

Please check dashboard too. You should get notice when driver gets enabled or disabled.
Break Lock only triggered when movement commands received before end of previous one.

Are you sure direction/limit pin is different than enable pin and enable pin is correctly wired?
Enable pin logic is too simple to cause kind of issue. It does have effect only at start and end of printing. It could not make difference other places.

Re: Bug with Enable Pin set to "Enable before each print"

OK, i will investigate further, thanks. I had to do some prints really quick, so there was no time to look into it and i switched it back. Will report as soon as i know sth.

Cheers^^
