HD2x - Heat Bed Movement (Type 2 & 4) : Technical Assistance

Description:

The following instructions guide you troubleshooting issues regarding the bed not lowering or rising, particularly if there is a grinding sound associated with the bed movement. Please check your threaded Z rod housing number and ensure that it says #2 or #4, as shown in the photo below. If the Z rod housing says 1, then please see Heat Bed Movement Type 1 first for troubleshooting.

Process:

You will need the hex wrench set that came with your printer. You will also need a table so that you can access the two screws underneath the far right printer corner easily.

1) Locate the right smooth Z rod, as shown in the photo below

2) Loosen the two screws for the smooth Z rod foot in the top right corner of the printer.

3) Carefully move the printer so that the bottom right corner of the printer is slightly off the edge of the table. This should allow you to access the two screws on the right smooth z rod bottom foot. Keep one hand on the printer to make sure that it is secure. Loosen the two screws which secure the right smooth z rod bottom foot in place.

4) Lower the heat bed to the bottom of your build area. You can do this with Repetier-Host or using a Viki if applicable.

Repetier-Host

Go to the manual control tab and press on the up arrow in the center control icon

Viki Screen

Select Prepare, then navigate to Move axis --> 1mm --> Z --> and then increasing the number shown. Increase the current Z value to bring the bed down.

5) Once the bed is all the way down,tighten the two screws for the right smooth z rod foot in the bottom right corner of the printer. The right printer corner should be off the table so that you can reinsert the screws from underneath.
