What to do if the measured path deviates from the set path?

Small deviations of a few hundredths are normal, because the spindles are more or less accu-
rate, and even ex works their deviations can have.

If the deviation to 50 mm is more than 0.1 mm, something is wrong, check:

●

Are the spindle pitches set correctly?

●

Are these even right? Some machines have inch spindles! Measure exactly. Some spindles

are also worn unevenly.

●

Is the number of motor steps for the axes correct?

●

If there are slight deviations which are different each time, steps may be lost, loosen all axle

clamps, reduce the acceleration further as a test and check again.

●

Are the motors slip-free on the shafts? Grub screws don‘t always hold this tight, better are

keyslots with keys.

●

Is there a transmission in the powertrain that may not have exact round numbers? Then

adjust the number of engine steps until the result fits.

●

Is the motor current set correctly at the output stage?

In case of problems, we are happy to help solve the problem.

If all tests are successful, the machine is ready for operation!
