Q)  CNC laser cutting machine follower cannot move up to the correct height

(A)If the follower cannot move up or the lift-up height is incorrect, users need to first observe and determine
whether Z-axis coordinates are normal. If Z-axis coordinates get less obviously, it is required to first return to the origin, press repeatedly “FOLLOW” and “SHUT”, and then obverse whether Z-axis coordinates are consistent with each other after following to the board. If Z-axis coordinates continue to decrease, there may be a problem in the position feedback of the system. The reason may be that: servo motor or ball screw and coupling slide against each other, resulting in coordinate offset.
