Reassembly
14. Secure the print head shaft X
• Tilt the left and right sliding blocks to be able to place the print
head shaft X in the notch. Make sure that the end of the shaft is 1
mm from the left panel.
• While supporting the bottom of the sliding block, push down on
the end of the shaft until it clicks into place. Do this for both sides.
Tip: Check if the print head shaft X is activating the Y limit switch.
If not, remove the print head shaft X and click it in place further to the
left.
15. Secure the print head shaft Y
• Tilt the front and back sliding blocks to be able to place the print
head shaft Y in the notch. Make sure that the shaft is exactly in the
middle.
• Pull the end of the axle upwards until it clicks into place. Do this for
both sides.
16 Insert the Bowden tube
• Press down on the tube coupling collet in the print head.
• Push the Bowden tube all the way in.
Tip: Check if all four sliding blocks are completely upright and not
tilted.
Tip: To avoid bending the print head shafts, it is recommended to
place the print head in the corner before inserting the Bowden tube.
17. Ensure the Bowden tube is correctly inserted
• Let go of the tube coupling collet and gently pull the Bowden tube,
along with the tube coupling collet, approximately 2 mm upwards.
• Hold the tube coupling collet up with your fingernail.
• While holding the tube coupling collet up, push the Bowden tube
down again.
Note: This step ensures that the end of the Bowden tube connects
correctly to the TFM coupler. This prevents room between the
parts as well as play on the Bowden tube.
