M574 X1 S1 P"io4.in"
M574 Y1 S1 P"!io1.in

Why is one of these inverted and not the other?

Did you verify that each is working by manually triggering them and running M119?

I forgot to mention that issue with G32 having the same problem is bed.g issues G28 which runs homeall.g which is where the problem is.

Frederick

mrenz999

@fcwilt both work correctly. Different end stop switches.

mrenz999

@fcwilt so remove the G28 ?

 G1 H1 X-500 Y-500 F3000 ; move quickly to X and Y axis endstops and stop there (first pass)
 G1 H1 X-500
 G1 H1 Y-500
 G1 X5 Y5 F6000 ; go back a few mm

Why do you have lines 2 and 3?

that for corexy because they cant move independently.

execute each line of homeall separately and see where the problem is

G1 X222 Y201 F9000 ; go to first bed probe point and home Z
G30 ; probe the bed

Is that the line that makes your head crash?
Why probe at X222 Y201?

This isn't my problem - @mrenz999 was the OP - I'm just trying to help him.

Frederick

mrenz999

@o_lampe To probe the center of the bed.

@Veti So this is what I did. One line at a time. Commented out the first line G92 and it works correctly now. Strange.

I don't see a G92 in your homeall.g file.

Is that where it was?
