Lubricating the Lead Screws

DO NOT
use any oil or liquid lubrication on the lead screw as the POM nut will not operate properly.
Instead clean off the lead screw by using acetone or rubbing alcohol on a paper towel or cloth while
running the z-axis up and/or down. You can also use a cotton string by pulling it across one of the
threads as you move the z-axis up or down.

Aligning the Lead Screws

If the z-axis is binding or the lead screws come out of alignment, there are 4 spots you can loosen and
adjust.
1. Loosen the set screws from the coupler attached to the motor and make sure the lead screw is
straight. We recommend tightening the set screws a little at a time alternating between them
each time to ensure it stays straight. Look for a flat spot on the lead screw to line up with one of
the set screws.
2. Loosen the two bolts holding the lead screw to the x-axis carriage and POM nut and let it settle
in the correct position. Then re-tighten.
3. Loosen the top pillow bearing plate where it connects to the frame of the printer. Then run the
x-axis arm to the top and re-tighten the plate wherever it settles.
4. Lower the x-axis arm slightly from the top so you can loosen and re-tighten the set screws on
the top pillow bearing (attached to the top of the lead screw).

LCD Screen Breakdown

The gMax 2 PRO uses a 3.5" responsive touchscreen with an STM32 processor and open source
firmware. The screen firmware is independent of the printer firmware and must be updated separated
via an SD card. Note, due to it's open-source nature, some settings are visible that so not pertain to the
gMax 2 PRO. Review the categories below for more information.
