gMax Initial Run (Required)
LCD Screen Breakdown
1. You must run the supplied gcode file to test your gMax printer
aer transport. Slide the SD card (upside-down) into the leside
of the LCD screen.
2. On the LCD screen, the noficaon area will say “Card Inserted”.
If not, try removing the SD card and reinserng it and make sure
the “lock” is in the offposion on the side of the card.
3. Select “Print > TFT SD > gMax IniƟal Setup”.
The test file will perform several funcons:
• X, Y, Z Axis Motor test (slow and fast)
• Mulple Homing Test
• Extrusion test (with heat)
• Fan test then cooldown

1. To run the bed leveling roune go to “Menu > Movement > Bed Level > BBL > Start”.
2. Wait for the bed leveling roune to finish then click “Ok” to save the mesh to memory. The bed
leveling mesh will automacally load when you start a print.
Manually Level X-Axis Arm
Bed Leveling
1. Turn the couplers that connect the z-axis motors to the lead screws.
2. Clockwise will raise the x-axis arm and counter clockwise will lower it.
3. Line up the top of the arm to the nearest bolt hole on the linear rails for
both leand right lead screws.

The gMax 2 PRO x-axis arm should be manually leveled prior to bed leveling especially after it has been shipped.
The easiest method is to turn the lead screws with the printer turned off. If the arm is not level the z-axis may bind
while it tries to lift.
The gMax 2 Pro uses Bilinear Bed Leveling (BBL) in marlin to probe the bed and create a 3d mesh for the first
layer. The mesh is saved to memory and helps ensure the extruder lays down a proper fist layer. It is important
the x-axis stays level relative to the bed. If it changes you must re-run the bed leveling. We recommend running
the bed leveling command before any large prints
Note
Make sure to turn Bed
Leveling on after the leveling
has completed if it is off.
Your First Print (Required)
Printing Status Screen
1. Aer conducng the Inial Run and leveling the arm, this first print will confirm that your gMax is
running the same as when it lethe manufacturing facility. This is a necessary and useful print.
Make sure to run it with the supplied filament and on the cold acrylic bed.
2. Go to “Print > TFT SD >Your First Print”. As the prinng
begins, you will need to adjust the first layer height using the
Babystepping feature since it is set intenonally high from the
manufacturing facility so as not to damage the bed. Refer to
the next page for more informaon.

Removing the Print. Strength vs Finesse
1. If the bed is acrylic, aer the print finishes you can immediately remove it.
If you are using a heated bed, turn it offand let it cool several minutes before removing or you risk
damaging the print surface or warping you rpart.
2. If the first layer printed correctly you should see no curling at the edges.
3. USING CAUTION, take the scraper and gently tap at the edges of the print. Look for corners of the
model and tap them. Aer several taps the print should pop offthe bed. If the model has a large
surface area on the print bed, it may be harder to remove and you may have to slide the scraper
below the model.
Tap Edges or
Corners
The scraper is very sharp.
NEVER place your hand
behind the area you are
scraping and take caution
not to dig into any build
surfaces.
