Plate Holder Assembly

1

Insert 2X 2 10×2 magnets into the plate_carriage, ensuring both sets are aligned the same way

2

Place the plate_pincher on top, aligning the magnet carrier with the magnets in the plate_carriage. Place 2 10×2.0 magnets into the plate pincher to hold the two parts together

3

Place the plate_support on top of the plate assembly

4

Place the plate_background on top of the stack and push down

5

Place the plate stack onto the x axis linear rail carriage

6

Insert four M3x12 WHCS screws through the plate stack into the x carriage. Do not fully tighten yet

7

Using the grid paper, ensure that the plate stack is aligned parallel with the x axis linear rail. Once aligned to the best of your ability, fully hand-tighten the four M3x14 WHCS screws onto the x axis carriage in a cross pattern

8

Check to see if the plate_pincher snaps and in out freely

9

Secure the plate stack with five M3x8 WHCS screws

10

Route the x axis belt as shown

11

Ensure belt teeth are facing inwards in the loop and open ends terminating at the plate_carriage

12

While holding the belt in place and centred, secure the belt onto the plate_carriage using the x_belt_clamp and one M3x8 SHCS screw

13

To adjust the belt tension on the x-axis, turn the tensioner screw clockwise (tightening) if needed. The ideal tension ensures the belt grips the motor pulley’s teeth firmly enough to prevent slipping, but isn’t so tight that it puts undue stress on the bearings or printed components. A good rule of thumb: with the motor off, you should be able to gently press the two sides of the belt together using just one finger. The belt should depress slightly (about 1–2 mm) and then spring back to its original position

14

The idler assembly should be within the window of the x_axis_tensioner. If not, the position of the belt in the belt clamp should be adjusted and tensioned again

15

Move the plate holder around manually to ensure both axes move freely. There should be a subtle resistance from the stepper motors

16

Check the position of the belt on the pulleys to ensure that they are centred and listen for grinding/rubbing noises. If belts are off-centre, adjust the position of the motor pulley or belt clamps
