Deep lines carved

The cover bolts to the heat sink from behind. The encoder is on the back of the motor.

Sawdust in the z encoder has caused those for me before. Also I've seen erratic z errors when I had a flakey FFC Cable.

Encoder 101.

You can use Sensor Data to monitor the pulses moving the Z by hand to check it too. Smooth counting.

blew it out still getting lines....any other suggestions? can you get just the encoder without the motor?

[bergerud]

Do you see anything wrong with the encoder?

(The encoder cannot be bought separately. It is, however, the same encoder as in the board tracking sensor.)

[saylesj]

it doesn't appear to have anything wrong

I would guess the problem is elsewhere. Look for play or stiffness in the truck system.

Mechanical of the truck?

Grasp the truck with two hands and try to twist it in the X and Y direction looking for a loose roller rail bearing letting the head rock on the rails.

Remember the roller rail bearings have 2 adjustments... Crimp on the rail and tightness of the actual screw holding the bearing. The Crimp may be loose.

Some have found a loose screw under the machine going into the smooth vertical rails that the whole head assembly goes up and down on.

Some WAG's... Wild AL Guesses...
