Bed leveling going to wrong side.
-
Hello,
Despite the printer homing and moves well the bed leveling is not working. The printer seems find the correct start point, however, the head moves to the oposite side, out of the bed. Need help, thanks. Moving from left to rigth, should be the oposite.

I think you might have your coordinate system messed up.
When looking at the front of the printer, 0,0 should be in the front left corner of the bed. -X should move to the left, +X to the right. -Y to the front, +Y to the back.
Your endstops are configured as being on the high end of travel. So your homing moves would move the print head to the right and back of the printer. Is that right?

Hello @Phaedrux
Thanks!Its moving to the right and front - Is exactly where it homing. Is it possible to change the probe position start manually? same as homing.

@esobreiro if your bed homes front right, this X maximum and Y minimum. So you need to change your Y endstop from maximum to minimum. Change Y endstop to:
M574 Y1 S1 P"!ystop"
However, changing this may show other problems. Have you checked your CoreXY motors go the correct way when commanded? See https://duet3d.dozuki.com/Wiki/Test_axes_or_motors_individually

Please post your homing files as well. When you change the Y endstop you'll also need to change the direction of the homing move.
Actually this isn't too bad. The A B motors are in the back, so it's just a 180 degree flip of a corexy. The "front" of the machine is arbitrary, so as long as the 0,0 point is the front left and the X Y movement directions are correct your coordinate system will be correct.
Corexy can be tricky.
Go through this document. It has tests for movement to make sure things are setup correctly for corexy.

@droftarts i tried but was not good...

@esobreiro said in Bed leveling going to wrong side.:
G1 H1 Y305 ; then move slowly to Y axis endstop
When you change the Y endstop to be at the minimum side, you must then also change the direction of your Y homing moves from positive to negative. (and your back off moves from negative to positive)
-
@Phaedrux said in Bed leveling going to wrong side.:
-X should move to the left, +X to the right. -Y to the front, +Y to the back.
Is this how it's moving?
-
@Phaedrux Thanks again.
I did that because of this problem... I just revert and no success.
Now its homed at X:60 Y:30 with same behaivour.Best regards,
Erick

Take a look at this post it will lay out what you'll need to do to get the coordinate system correct.

@esobreiro said in Bed leveling going to wrong side.:
but....
-y=backOk, that's a starting point.
Go through this test:
https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Testing_motor_movement
It will help you figure out what needs to change. It's likely that either one of the motors need a direction of rotation change and/or the motor plugs swapped. It will help you figure out which.

Not so fast...
After following the belt schema now, I have half bed and the following errors:

Is your probe really x180 and Y100 away from your nozzle tip?

I revert the firmware from 3.2 to 2.05.1 and everything is working fine. Thank you!
