2nd Printer, same issue with steppers only going diagonal

[Phaedrux]

What firmware version are you using? Because the expected Y motor behaviour is different between 1.18 and older and 1.19 and newer.

test the Y motor by sending from the console:

G91
G1 S2 Y10 F3000
For firmware 1.19 and later: If the head moves diagonally in the +X and -Y directions, all is well. If it moves in the -X and +Y directions, change the S parameter in the M569 P1 command to S1.

For firmware 1.18 and earlier: If the head moves diagonally in the -X and +Y directions, all is well. If it moves in the +X and -Y directions, change the S parameter in the M569 P1 command to S1.

Also can you verify that you have a right handed coordinate system? with the origin 0,0 in the front left corner? Y moves in + towards the back of the printer towards the endstop?

M667 S2 Z3 ; set CoreXY mode

Are you sure you have an XZ printer?

[Phaedrux]

@joergs5 Good catch!

[interwebsdesigner]

@phaedrux 1.21 is the version. And yes, 0,0 should be at the front left corner. I have my first build which this is identical to also and works appropriately.

@joergs5 good catch indeed. That was it. Silly mistake when going through the docs sent above. Everything is working as expected. Maybe by the 3rd one I won't have trouble Thanks guys.

@interwebsdesigner The mistake was not easy to detect, because the comment said XY.

Nice that so many people use CoreXY.

What was it?

I wasn't able to follow the back and forth.

Thanks.

@fcwilt it was set to core XZ mode instead of core XY

Thank you.

What is a Core XZ printer? I cannot visualize how that would work. Any videos or pictures of such a printer?
