To check the adjustment of the Z-axis limit switch:
1.
Press the LCD button; menu will display.
2.
Go to “Prepare” and select; menu will display.
3.
Go to “Auto Home” and select.
4.
The hot end and print board assembly will move to 0,0,0 position.
NOTE:
If you hear any
noise, stop and troubleshoot. Causes may include: belts may not be aligned, yellow
thumbscrew not released, may need to apply grease to Z-axis lead screw, end stop switches
are not functioning properly, etc.
5.
Tighten the yellow Z-axis lock thumbscrew to lock the print board so it can’t move up or down
along the Z-axis.
6.
Press LCD button; menu will display.
7.
Go to “Prepare” and select; menu will display.
8.
Go to “Disable Steppers” and select. This will allow you to move the hot end and print board
to check the gap with the card. The card should be moveable with only slight resistance.
9.
If the gap is correct, you’re done. If the gap is too tight, turn the Z-axis end stop screw ¼ turn
clockwise. If the gap is too large, turn the Z-axis end stop screw ¼ turn counter-clockwise.
10.
Loosen the yellow Z-axis lock thumbscrew, then use the Z-axis knob to lower the print board
a few inches.
11.
Re-check the adjustment of the Z-axis limit switch by repeating the previous 10 steps until
the gap is correct.
NOTE
: This full process for print board leveling typically only needs to be done when you are
assembling the printer from the kit or if the print board get way out of level. For day-to-day use the
print board should stay level. Always remove the print board before attempting to remove a printed
part from the print board. Attempting to remove a part from the print board while it is still connected
to the printer is a quick way to get your print board way out of level, and very well may damage the
printer.
