1- Alignment

Part 1: Preparation

Set the printers you want to joint next to each other on the surface they will be placed on.

Remove the magnetic print surfaces of the printers.

Part 2: Leveling Face to Face Printer Beds

Push the beds of the two printers you want to join face-to-face together.

Check the height difference of the beds along the joining edge.

adjust the feet under the bed to get this edge of the bed level with each other.

Take a straightedge or level and put across the beds.

They are likely angled away from each other in a ‘^' shape or angled towards each other in a 'v’ shape.

Adjust the feet under the printer to angle the beds until they are level with each other.

Part 3: Joining Face to Face Printers

Loosen the two M4 screws on the edge bracket with a 3mm Allen key.

Don’t remove the part, just loosen it enough that it can move around.

Take two 30mm M3 screws.

Screw the edge mount bracket to the corner mount.

Make sure the printers are aligned with each other before fully tightening.

Tighten the two M4 screws on the edge mount bracket.

Repeat on the other side of the printers.

Part 4: Leveling side by side printers

Push the beds of the four printers you want to join side-by-side together.

You can join just multiple single printers side by side in this way, but if joining any face-to-face, do that first.

Check the height difference of the beds along the joining edge.

adjust the feet under the bed to get this edge of the bed level with each other.

Take a straightedge or level and put across the beds.

They are likely angled away from each other in a ‘^' shape or angled towards each other in a 'v’ shape.

Adjust the feet under the printer to angle the beds until they are level with each other.

Part 5: Joining side-by-side printers

Loosen the two M4 screws on the homing bracket with a 3mm Allen key.

Don’t remove the part, just loosen it enough that it can move around.

Take two 30mm M3 screws.

Screw the homing bracket to the corner mount.

Make sure the printers are aligned with each other before fully tightening.

Tighten the two M4 screws on the bracket.

Repeat on the other side of the printers.

Part 6: Checking level with print surface

Place the print surfaces on the joined printers.

Check that the surfaces are level with each other by feeling the seam between them.

There should not be a raised edge in either direction.

If one edge is raised, you may need to adjust the height of the print beds to align them.

To account for small height differences, offsetting the print surfaces to overlap onto the adjacent beds can sometimes help.

Part 7: Leveling arm

Check the level of the Z-axis rail (preferably with a digital level)

You can use your phone with a leveling app.
Use the flat faces of the rail to place the level on.
The arm may be out of level by over a degree, we want to get it within 0.1 degrees of level.

If you need to adjust the level of the arm, first loosen the four set screws on either side of the arm base by a couple turns.

the arm and bed are not fully attached now, try not to move the arm around on the table until you re-tighten the screws.

Adjust the two feet under the arm base to shift the Z-axis to a more vertical position.

Recheck with your level during the process.
Try to get both the back and side of the axis to read as close to 0 as possible.
Re-tighten the set screws on the arm base.

Don’t forget to re-tighten the set screws.

Part 5: Calibrating Printer Software Alignment

Print Align test son two adjacent printers.

Measure how far the squares are from being aligned from each other.

Tip: When shifting the calibration to align the printers, align one corner printer to it’s own bed, then leave it alone and align the others to it. This helps simplify the process.

Input the X & Y distances to align to the adjacent printer into the solver.

Retry the print.

Check the new printer alignment.

If they are aligned, move on to the next adjacent printers.
