CoreXY: X is now Y, Y is now X
-
@phaedrux Since I built it with the original Duet Wifi and changed to a Duet 3 6HC, X0 Y0 was in the front left corner. X move left/right, Y moved front/back.
Now it doesn't, it swapped X and Y.
-
Yes, I understand.
Where are you endstops located now?
-
@phaedrux The tests are viewed from the front, where the M M is on your graphic and where the PanelDue is mounted.
One endstop is on the left of the extruder carraige, was the X. It's mount on purple petg to the left of the wirechain bracket in the photo. The other one the front of the right carriage wheel plate of the extruder axis, was the Y. It's mounted on red pla in the photo.
-
@phaedrux Just ran a test print with lettering. I was only expect one reverse axis, but both are reversed. Looks like X0 Y0 needs to change.
-
Ok, so if the X endstop is on the left it's at the low end. So M574 X1 and the homing moves should move in the negative direction.
If Y is triggering when the print head is towards the front, then it's at the low end. M574 Y1 and the homing moves should be negative direction.
Now based on the tests here: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Testing_motor_movement
Start with
M569 P0 S0 ; X motor runs forwards
M569 P1 S0 ; Y motor runs forwardsThen send
G91
G1 H2 X10 F3000And
G91
G1 H2 Y10 F3000What do you get?

Ok so..
If it moves in the -X and -Y directions, change the S parameter to S1 in the M569 P0 command.

Move diagonally toward front right coner.
Ok so...
If the head moves diagonally in the +X and -Y directions, all is well.
Ok, so change to M569 P0 S1 and retest.

@phaedrux
M569 P0.0 S1 ; physical drive 0.0
M569 P0.1 S0 ; physical drive 0.1Fixed it. Set the enstops back to normal. As I recall, my first setup on Duet Wifi took a several days.
One of these days, I'll understand this thing better.

So everything is back to normal now?

@phaedrux Yes, it working normally. X is X and Y is Y.
