CoreXY: X is now Y, Y is now X

@stephen6309 said in CoreXY: X is now Y, Y is now X:
Current Firmware 3.3RC1 on 6HC w/Pi4 and 1LC.
X is now going Y direction.
Y is now going X direction.
No hardware changes.
Going back to 3.3beta3, no change.When exactly did you notice the change? After updating the firmware? And going back to previous firmware didn't change anything?
I'm a bit confused about what might have changed.
Does -x move to the left, +x move to the right?
Does -y move to the front, =y move to the back?X endstop is still on the left side?
Y endstop is on the front side?Can you post the results of M122 and M122 B1?
Also the results of M98 P"config.g" please. -
@phaedrux X endstop is now front right (makes a mirror print on X)
Y endstop is one left of axis the extruder is on.
It was X endostop on left of extruder, Y was homing to the switch front on right side.
Bed is 400x300. Was 400 on X, 300 on Y.
Was going like X & Y on a cartesion like my other printer.Since then X & Y have swapped, X is now 300, Y is now 400.
Also, updated 6HC to 3.3RC1+1.
It occured when updating to 3.3RC1 via DWC, the apt-get wasn't updating to it, and I made a new config on the configurator, since I had the wrong config.json for the printer. Going back to the prior config.g didn't change it.

Ok, so your motors are at the "rear" so 180 degree flip from "normal". I use quotes because it's all relative.

That makes very little sense. Regardless, we can fix it to make sense again.
Let's start from the top with our absolutes.
0,0 will be the front left corner of the print bed.
-x will be left, +x will be right
-y will be to the front, +y will be to the back
X endstop is on the right side/high end (M574 X2)
X homing move will be positive (G1 H1 X+500)
Y endstop is at the front/low end (M574 Y1)
Y homing move will be negative (G1 H1 Y-500)
Your slicer might need to reflect this as well.Those facts do not change.
Now with that set in stone, do the motor tests again. This will help you determine what needs to happen next. Either swap motor connectors, change direction of rotation, etc.

Can you confirm that firmware changes (back and forth) were applied to both boards?

On the config.json, it like to keep it current with the config.g. The json was for a different printer. So, I remade it by copying the currect config.g settings. Copied the new congi.g and json into system. It would be nice configurater needs to be able to make a config.json from the config.g file.
0,0 will be the front left corner of the print bed.
Yes it is.
-x will be left, +x will be right
-y will be to the front, +y will be to the backThat's the way it used to work.
+X currently goes back
+Y currently goes to the rightX endstop is on the right side/high end (M574 X2)
X was on left/low side.
X homing move will be positive (G1 H1 X+500)
Homing X has always been -X
Y endstop is at the front/low end (M574 Y1)
was on the front/low side on the right.
Y homing move will be negative (G1 H1 Y-500)
Homing Y has always been -Y
Bed moves up to home Z.Your slicer might need to reflect this as well.
Priusa slicer has nothing to due with what the printer is currently doing.M569 P0.0 S1 for the correct direction
M569 P0.1 S1G1 H2 X10 F3000: move the extruder diagonally back and left
G1 H2 Y10 F3000: move extrueder diagonally to left and backMy homeall.g was posted above. Works fine if I swap the X/Y endstop config. Otherwise, the endstops never trigger, since it's mi=oving the wrong axis.
My endstops used to configured:
M574 X1 S1 P"121.io1.in"
M574 Y1 S1 P"io2.in"
They worked as expected.FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.3RC1+1 ELECTRONICS: Duet 3 MB6HC v1.01 or later FIRMWARE_DATE: 2021-05-01 21:43:52
Duet TOOL1LC firmware version 3.3RC1 (2021-04-29 10:21:18)
The config.g is what is current. The way the printer moves, the the front/back axis, now X, is mirrored.
Home X, it now moves to the front. It was to the left.
Home Y, it now moves to the left. It was to the front. -
Have you moved the endstops from where they were originally? If you've changed things to accommodate the problem we're not actually solving the problem.
It doesn't really matter where the endstops are located as long as we're able to tell the firmware where they are and instruct it to move to hit those endstops.
Let's start from the top with our absolutes.
0,0 will be the front left corner of the print bed.
-x will be left, +x will be right
-y will be to the front, +y will be to the back
X endstop is on the right side/high end (M574 X2)
X homing move will be positive (G1 H1 X+500)
Y endstop is at the front/low end (M574 Y1)
Y homing move will be negative (G1 H1 Y-500)
Your slicer might need to reflect this as well.Those facts do not change.
This is how it should be and how it will be because we say so. If it's not currently doing that does not matter, we will make the changes needed to make it so.
So either move the endstops back how they originally were or leave them where they are, either way just let me know.

Part of the confusion may also be resulting from the 180 degree rotation with the motors in the rear. That would mean the expected movement from the tests would be inverted as well. Do you get what I mean?
The motors here are in the rear, as they are in your machine. This would be 180 degree rotation from the "normal" corexy where the motors are in the front side. This just means that the direction of X and Y are inverted from the expectation, placing 0,0 in the back right corner. The back right is the same as the front left, just rotated half way round. Does that make sense?
-
@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.

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