Dear Administrator:

I try to move Z step motor. It can be move to 250 mm.If it move more then 250 mm,it can't move. Z step motor must to down,and down to 250 mm, It can be move.

FluxBB bbcode test

======================================
0 mm ~ 250 mm --> Z step motor (Move)
250 mm ~ 500 mm --> Z step motor (NOT Move)
500 mm ~ MAX mm --> Z step motor (NOT Move)
======================================

If you are using RAMPS, it could be limit compiled in your firmware.
Error which you have highlighted is normal. RAMPS using mm or inch unit. But movements are all converted to smallest pulse unit so 250mm could be something else. On nanodlp side we try to make sure no error albeit small raise because of these unit changes.

Hi

I use marlin file and import to RAMPS. Marlin file name is "Marlin-mUVe1DLP-Running-master.zip".
