I printed all parts in ABS with 2mm walls and thicker for hinges
Cut out panels from sheet to nearest mm
Print joiners, all front door parts, door frame mounts and joiner first
Mount front door hinges by replacing current UM screw with a 16mm screw on each one
Use a 16mm Screw for the front door handle.
Glue a thin magnet to the back of the door handle and tape a magnet behind the UM front panel.
Use masking tape to hold panels together making sure that the top panel sits between the left and right panel and not on top of them
Mark holes and drill panels making sure Joiner L4 is positioned in the gap of the cable ducts
Mount joiners and door frame mounts with 10mm screws on panels
Use clear packaging tape to join and seal panels where desired
Glue Top Door frame to joiners right way up and don’t use screws
Put Door seal on the Top door frame
Tape top door in place with masking tape and use the Top Hinges Template to mark mounting holes for the hinges.
Use 6 X 16mm screws for the Top Body Hinges
Mount Left handle with 3 X 25mm screws and Nyloc Nuts
Thread thermocouple through the Thermocouple holder and attach it to the 25mm Left handle mounting bolts with nyloc nuts.
Push thermocouple far enough onto its holder so that the print head will miss it in the fully left position
Mount right handle with 10mm screws and nyloc nuts
Mount the 40mm fan to the fan shroud using 4mm screws
If printing in ABS use enclosure as is to print tall parts like the Bowden grommets
Ground wire goes from the Power Socket to the -DC terminal on the Temperature Controller and the Black wire on the fan.
12V positive from power socket goes to the +DC terminal on the Temperature Controller and to one side of the relay contacts.
The other side of the relay contacts goes to the red wire of the fan.
Glue the cable ducts in place
Duct Lid slides in position from underneath
Un-attach the Bowden cable(s)
Mount the Right Bowden grommets flush with the outside panel of the UM then the left flush with the outside of the UM and with the print head cables passing through the slot.
Join the grommets together with the 2 X 10mm screws there will probably be a gap between them
Set start temp at the desired temperature and stop temperature to 1 degree above that. (Picture shows set at 45 degrees with current temp at 25 degrees.
