My 2012 Solidoodle 2 Pro 3D printer’s original extruder got irreparably clogged, so I needed to replace the hotend. I decided to go with an E3D v6 1.75mm hotend (USA). This necessitated first disassembling the original acrylic, jigsaw extruder.
- 2.5mm hex key
- 4mm hex key
- small 5.5mm hex socket wrench, adjustable spanner, or 7/32″ hex socket wrench (in order of preference)
* In case it wasn’t obvious, the printer should not currently be plugged in and it should have completely cooled before you do any of this. *
Now all you need to do is the reverse of how it was assembled in the first place. Easy.
Unscrew the thumb nut from the spring-loaded tension arm and remove its components (nut, washers, spring, and bolt). Unscrew all the front-facing hex socket bolts using the 2.5mm hex key. Some of these bolts are secured from the other side with a lock nut; you will need to hold the lock nut in place with the spanner or wrench in order to remove the bolt.
Set aside the tension arm (or its pieces if you’ve taken that apart too).
