I am experiencing intermittent trouble with the spindle not
raising up far enough on the z axis.
it works most of the time, but now and then it wont raise like its supposed too. Any one else have this type of trouble? suggestions?
How often is this happen? When you orientate the system
does the Z-axis home as expected? My first thought is something is slipping I
would remove the top of Z-hood and check the Z-axis collar clamps. Check to see
if one of the screws is broken in the clamp. If the clamps are good then make a mark
across the lead screw and clamp & the pulley and clamp to see if you have slipping.
If you have confirmed nothing
is slipping then the next thing I would think is the encoder. All 3 motor on
this machine are the same so swap the Z motor with the Y motor.
If you want more
directions or have additional information call me at 1-800-828-5406 and have a call opened.
