Ender 5 Plus with dual z calibration
-
Seems to only do it when x and y are asked to work together
-
maybe the movement wasnt 45 degrees.
after homing. issue
G0 X0 Y0
then
G0 X100 Y100
that should be a movement where only one motor moves.
with the printer on I can move the belts without much force.
not printer on. motors powered. test this directly after a move.
-
Top belt needs a lot of force. Bottom very little
-
Y motor runs the top belt, x motor runs the bottom belt
-
measure the resistance of each phases on the cable connecting to the duet.
-
@Veti to both motors or just the motor having the problem. With power to the motors?
-
unplug the motor from the duet (with the duet off).
measure the resistance of each phase of both motors at the plug.
they should all be the same. -
2.2 ohms on both motors and each coil
-
do you know the specs of the motor?
i found a 2.2 ohm motor and that one is 1.7 A, which would mean you are running way to little current.
-
Kay3d told me 1.5a so I went to 1200ma and the stuttering got worse backed it down until the stuttering has appeared to stop at 1050ma
-
But still get a little stuttering but not nearly as bad
-
so can you confirm.
while the motors are powered, you can move one easily by hand and one not easily.
moving that motor to a different driver does not change this behaviour.
increasing the motor current makes it worse.on thing to test. disconnect both motors and move the head by hand. see if there is any resistance that feels stronger in some areas.
the next thing to try is to replace the motors with the original ones for testing.
also can you confirm that you are on firmware 3.1.1?
-
I went up to 3.2beta1 today just to rule out firmware.
-
Think I figured it out. I looked to be a combination of the wheels on y axis a little to tight and the motor amperage. I appreciate the help and you sticking with me through it.
-
stay with 3.1.1 for now. there were some reports with instability.
-
Will back it back down tomorrow thank you
