trouble with homing the x and y axes on a core xy printer.
-
Hello guys,
Thank you again for the heads up regarding the differencies between the machine config and the firmware that was on the board.
Today I went on and upgraded the firmware on the board, and reuploaded the machine config. At a first glance, the xy gantry seems to move in the right direction ; I still cant perform the homing on them. I also moved the z axis, on which I have 2 in series motors ( ZA and ZB are being used to control them), and while the z axis is performing the required movement , the E0 extruder motor is also moving.

this does not match your config
M584 X1 Y0 Z2:3 E4:5 ; set drive mapping; INIT:X=0; Y=1; Z2;E3:4Za and Zb are both driver 2
-
@Veti Thank you
-
The motors work fine, I still cant home the x and y
-
can you describe in detail what happens when you press homex
-
@Veti both motors receive current but the gantry does not move.
-
the x motor has an atempt to make a move , but to no avail.
-
@campeancalin
does it work with no belts? -
@Veti no, there's an atempt to start but it suddenly stops

You only have a single Z axis (even if it were split between multiple drivers) and the values for each motor would need to be the same, so there is no need for two values for Z. It shouldn't be a problem, but I suggest cleaning it up.
Z16:16 would become just Z16 for example.
So the X motor isn't moving when you press home all at all, or is it moving a few mm?
Does it move if you do the corexy motor movement tests?https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Testing_motor_movement
Also test that your endstops are working correctly. You can check their status by sending M119, check them when you trigger the switch by hand as well as untriggered.
And, finally once you have movement, just to confirm you are using a right hand coordinate system with 0,0 in the front left corner and X+ moves to the right, X- to the left, Y+ to the back, Y- to the front.

Does it move if you do the corexy motor movement tests?@Phaedrux, when I call for x or y homing command , the z axis prepares by lifting for 5 mm, but as far as the A and B motors, little to no movement at all ; the pulleys on the motors fell stiff as if the motors are trying to move . When I perform the movement tests they move the right direction. Only the home commands do not function

@campeancalin said in trouble with homing the x and y axes on a core xy printer.:
When I perform the movement tests they move the right direction.
At least that tells us that the motors are working and corexy is setup correctly.
@campeancalin said in trouble with homing the x and y axes on a core xy printer.:

Ok, please test the endstop switches as I described.
Move the print head into the center of the bed so that it's away from the endstops. It almost sounds like your endstop switches are misconfigured and showing as triggered when they are not.
@campeancalin said in trouble with homing the x and y axes on a core xy printer.:
little to no movement at all
How much exactly? none, or some? The homing macros have a move to the endstop switch, and then a backoff movement. IF the switches are misconfigured and show as triggered when they are not, you wont get any movement on the first homing move, but the back off movement should still work if the directions are correct.
-
I performed a test by homing the y axis while I had the switch lever pressed, and the motors started moving . I think the switches are misconfigured.
-
after pressing home x it should have shown that x was homed in the ui.
change to this
M574 X1 S1 P"!xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"!ystop" ; configure active-high endstop for low end on Y via pin ystop
-
Yes. The "!" marked the spot. Thank you.
-
@Veti same thing for the Z axis?
-
No, your Z axis is configured to use the probe.
