Problem setting up core XY
-
can you move any of the belts by hand while the motors are energised ?
-
@Veti When the motors are on After homing and energized I cannot move by hand
-
I'm easily confused.
The belt angles don't look so bad from above.
What are the motor specs?

X Moves correctly
Y Moves correctlyThe 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.
i am also getting confused as this does not match
could you please restate your problem.
stating exactly which command you are issuing. -

M92 X160.00 Y160.00
a normal blv setup has 16 tooth pulley which would give you X200 Y200
are you sure both motors are 0.9 degrees? if one is 1.8 that could give very strange results.

blv require full d-cut shafts. could the pulleys be slipping?
-
@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 Hopefully that is it I do have another S1 I am swapping them out right now.

did you buy the blv kit?

the 2 17HM19-2004S1 are for x and y
and 1 17HS16-2004S1 for e

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

@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. -
How do I mark this solved?

Topic tools, ask as question, and then topic tools again, mark as solved.
