1: Cutting pliers
2: Philips head screw driver
3: Small tiewraps
4: T10 Torx screwdriver
5: Some heatshrink or a marker
6: Sharp scissors
Jog your printbed to lowest position, and unscrew the 4 corners. (T10 torx)
Then put it in the highest position.
Remove the back cover, using the T10 torx.
CAREFULLY cut the tiewraps place by XYZ. Remove the plug with blue wires gently and the red/black on the right hand side. Again be GENTLE. The connectors are not the sturdiest you'll ever find on a PCB. Unscrew the wires for the heatplate and then remove the ferrite clamp on the loom. You can put that aside for now.
Gently work the loom through the hole into the chamber of the printer.
Unclip this connector, underneath your printbed. Now your printbed should be completely free and you can take it out of the printer with the loom still attached to the printbed.
(I was forced to take it out due to a print not coming off.
Undo the loom of it's plastic 'shell' (i'm not sure about what's it called, so if anybody knows the word let me know :))
This might require you to cut some tiewraps. Just be carefull when doing so.
As you have marked one of the cables, you can now cut this cable and then connect it with a connector of choice, as long as it's completely isolated. Cut through with cutting pliers, then to strip them, use some sharp scissors and make some rotations on where you'd like to strip the wires. This is easier then with cutting pliers and will leave the internals intact.
While doing this, make sure that you put the 'female' side of the connectors on both wires going to the mainboard. And then use the 'male' part of the connector on the printbed sides of the wires.
Place back the plastic shell of the wireloom.
Work the side to be connected to the main board back through the same hole.
Reconnect the wires as they should. Remember which cable you marked and where to place it on the connector for the heating elements. I placed one tiewrap just before the ferrite clamp so i'm sure it's stuck and won't be slamming around.
Reconnect this plug.
Place your printbed and connect the newly placed connectors.
Turn on your printer and lower the printbed.
Screw back the printbed holders and don't forget to thread the blue wires through the screws on the back side of the printbed.
Now if a print is stuck, you can quickly change the printbed and start printing again, while taking your time to carefully remove the stuck object. Also this allows you to switch between alu/glass/other printbeds to meet your requirements.
