M675 probe cavity issues

kouta10

Hi, I am hoping someone can help me with this. I can probe on xyz using m585 with configured endstop, but i cant get m675 to work. This is what my macro looks like,

G91
T1
M675 X10 E3 L0 R2 F500

When I run the macro the machine starts moving in the -x direction and when i trigger the end stop nothing happens. It wont stop moving on the -x direction until i hit the e stop.

This is my config.g file

@kouta10 said in M675 probe cavity issues:

M675 X10 E3 L0 R2 F500

I don't think X10 is correct. It should just be X to denote the X endstop. Not sure where you got L0 and E3 from either.

@Phaedrux if i got my x end fixed at low end of axis, how does that work? If cavity is in the middle of the bed, x never gets triggered.

kouta10

The hole idea is to use probe as trigger for cavity, i don't see how that works any other way unless i understood it wrong.

Did you correct your M675?

I'm not sure I understand what you mean.
