Description
UPDATED...
I've just uploaded 2 new STL files.. they are
New updated mainboard base. This allows the cables to come out at the back rather than the side. One hole is for the bed plug and the other is for both the extruder and side connector cable, make sure you feed the big plugs through first. Oh, and don't forget to put your grommet in first.
The other STL in a new LCD screen which I've added a little slot for a zip tie to attach it to the upright.
I've also released a firmware (Marlin 2.0.6) to go with this mod. Grab that from www.pretendprusa.co.uk
Conversion kit to get rid of the external control and PSU.
Conversion items required
LCD Mount
2 off M4x10 (cap head or dome) set screws
2 off M4 T-Nuts
PSU Mount
2 off M3x10 (dome) set screws for the power connector
2 off M3 Nyloc nuts for the power connector
2 off M4x30 (cap head) for PSU mount
2 off M4 T-Nuts
220mm twin 24v power cable (original not long enough)
3 off M4x10mm screws to hold the PSU in
Self-tapping screw to earth into the aluminum frame
PSU Bracket
2 off M4x10 screw
2 off M4 T-Nuts
Mainboard Case
4 off M4x30 (cap head) for Case mount
4 off M4 T-Nuts
5 off M3x30 (cap head) for lid
Feet extenders
You might get away with using the supplied ones, but I used M5x30 I think they were.
Screws used from the original are the mainboard and LCD mounting screws
LCD Assembly
Build up the LCD mount with the screen, ribbon cables and screws. You will need to remove the side brace and cap, then slide the LCD mount with the screws in. Re-attach the brace and align and tighten the LCD mount up in the correct place.
PSU Mount
Insert the switch and the power connector and secure. Put all the wires through and once attached slide the PSU into its housing and secure with the 3 off M4x10mm screws. Mount on to the aluminum frame via the two T nuts. Slide the support bracket on and secure
Mainboard
Insert the mainboard and secure it. Insert both the wiring harness and bed connector. Attach the ribbon cables that are already attached to the LCD and mount via the 4 M4x30 and T-Nuts. Wire up the board and then put the 40mm fan and fan shroud in place. Finally, secure the lid in place.
I printed this all in PLA, only required supports for the PSU mount.
