Tramming Back and Base Assembly
We need to check the start friction, turn the torque coupling (that is at the bottom of the lead screw)
that we just installed left and right a few times, you will notice a heavy drag and possible binding on
the print platform just make a mental note of how much strength it takes to rotate the rod.
During this test the lower clamp to
stepper motor should not be tightened
so that the motor is not rotating and
only the drag of the rod is felt
Now to fix this problem, refer to diagrams 2.2a to 2.2c and loosen all the noted screws
in order.
Loosen them just enough that there is no contact with
the screw head and frame (Example on the right).
First loosen these 7
screws at the back
Then loosen these screws on
BOTH sides of print platform
