I attempted to shim a corner but it looks like it will take quite a few shims. Should I continue to lift one side with shims or move the “ledger” board and top motor mount board to put them into level?
it should not be very important, the sled hangs from two points, if you tilt
things significantly, accuracy may suffer in the bottom uphill corner of the
machine where the gravity vector is already small
The closer any chain gets to vertical, the more accuracy suffers. Tilting the
machine will make one corner be closer to vertical and the other further from
vertical.
Unless you are really tilted, I doubt you will notice any difference in the
cuts.
After going through calibration with the test sled it seems pretty accurate, was able to get the distance Horizontal and Vertical to both measure right at 23.75"
I am making some modifications to the sled and I will attempt to cut an object out and measure its accuracy.
