Step 2: Remove Bed Fastener
Using a 4mm hex and 10mm socket remove the three M6x75mm countersunk screws holding down the bed. Set this hardware in a safe place as we will be reusing them.
Step 3: Unplug Connectors
Unplug the heater and temperature connectors located at the rear-left of the spider plate. Take note of the release tabs shown below:
Step 4: Replace Bed
Now that the old bed is free, you can proceed to swap it out with the new one. Take note of the 3 locating features on the ALCA5 plate. There is a slot, point, and planar surface that should mate with the corresponding ball point set screws on the spider plate.
Step 5: Reinstall Hardware
Insert the M6x75mm countersunk screws into each of the three holes.
Reinstall the washers, spring perches, spring, and nylock nut in the correct sequence according to the diagram.
Torque the nylock nut until there is one full thread exposed on the end of the M6 screw.
Step 6: Reconnect Connectors
Reconnect the bed heater and temperature wires.
Power the machine back on.
Step 7: Check Bed Calibration
