How do I mark this solved?

@Veti If you could see me now I am doing the happy dance problem solved unbelievable I've been fighting this for a while. This is printer number 2 and I'm still working on printer 1 modifying changing never-ending Hobby/business. I also have in the works a large Core XY HEVORT.

@Veti Yes I did, will have to check the Z.

@Veti Hopefully that is it I do have another S1 I am swapping them out right now.

@Veti You could be onto something the two motors on X and Y Part numbers are different and I think it means one is .9 and one is 1.8 Looking up and trying to verify right now.

@Veti When the motors are on After homing and energized I cannot move by hand

@Veti M669
Kinematics is CoreXY, matrix:
1.00 1.00 0
1.00 -1.00 0
0 0 1.00

@Veti G1 X25 Y250
G1 H0 X25 Y250
H1
H2
AND
G0 X25 Y250

These are some of the formats I've tried and I have not used the H3.

@Veti

@mrehorstdmd Just me and my core XY cube build

A lot of great comments and information and I appreciate the time that everyone is put into helping me solve this issue. I'm continuing to read through and try everything everyone said I am continuing to have the same issue where I cannot move either X or Y By themselves The web controller shows example X25 Y25 I move to X25 Y200 The web controller shows X25 Y200 but You can tell X has moved to 150 and Y is at 200.

@Veti I was wondering if there was a problem with the parts I purchased from a supplier in China BLV Does not promote that supplier anymore.

Here are static photos of the machine and the setup of a BLV CUBE. I am working on videos of the problem

@markz That was a good thought I realized I change motors in an attempt to solve problems and put in two different size motors Presented the same problem. Change back to two a day at home motors still have the problem.

@mrehorstdmd When I say moved correctly I have a Macro created for Test movement
Test for the correct X motor movement by sending these commands from the console:

G91
G1 H2 X10 F3000
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 to S1 in the M569 P0 command. If it moves towards +X and -Y, or towards -X and +Y, then either turn the power off and swap the X and Y motor connections, or use M584 in config.g to swap the X and Y motor drivers over.

When you have the X motor moving correctly, test the Y motor by sending from the console:

G91
G1 H2 Y10 F3000
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. [Different rules applies to firmware 1.18 and earlier].

Important: make sure that you have chosen a right-hand axis system. That is, looking down on the printer the +Y direction should be 90 degrees anticlockwise from the +X direction. If instead it is 90 degrees clockwise, you have a left-hand axis system, which will give you mirror-image prints.

head moves diagonally in the +X and +Y directions
head moves diagonally in the +X and -Y directions

I thought I was onto it I had replaced the motors with the different ones that were different .9 and 1.8 deg So I just put the originals back in that are the same motors on both sides problem still exists.

Some possibilities come to mind...

loose drive pulley(s)- inspect DONE
not operating in corexy mode- config looks OK DONE OK
different size pulleys on the motors - inspect carefully DONE CHECK
bad cable/connector to motor(s)- inspect thoroughly DONE CHECK
bad driver chip- try swapping another driver SWAPPED BOARDS STILL THERE.
extremely bad layout that lets belt slip on pulley(s : Would not think so created a BLV mgn Cube WITH CNC parts.

@mrehorstdmd No problem with keeping it basic I have accomplished a lot in the last year and a half with Building 3-D printers. This is the first problem I have not been able to overcome. My bottom left corner would be 0,0 Upper left would be 0,300 Upper right 300,300 Bottom right 300,0. Everything seems to be in order and moving in the right direction but my example would be moving from X50 Y50 to X50 Y300 I cannot seem to move in a straight line as it moves toY300 it moves X50 to -number And crashes into the side the same goes for the X-axis move from X50 Y50 to X300 Y50 Moves on the Y-axis also and crashes. Tool Position on the monitor does not show movement on the static axis When make move from X50 Y50 to X300 Y50 crashes on Y but shows Y50 on tool position.

@Phaedrux said in Problem setting up core XY:

-x should move to the left, +x should move to the right
-y should move to the front, +y should move to the back
0,0 should be the front left corner
Also please tell us where the endstops are located.
If X is on the left side, then homing move for x should be negative. If it's on the right side, homing move for x should be positive.

X Moves correctly
Y Moves correctly
0,0 Front left corner
And stops are located on the left
