a box for all the electronic for your printer, designed to be set on top of the pc power supply with the smart controller, LCD knob and reset button on front.
design to be used with http://reprap.org/wiki/RepRapDiscount_Smart_Controller but could do with other ultipanel (with some adjustement for the lcd fitting)


print and glue the part, fix the panel with the LCD the last one , use the small ribbon cable provided with the smart controller. don't glue the lcd panel until the system is working, the pololu pot for the motor current will be more difficult to reach (not impossible but not easy)

designed to be used with http://reprap.org/wiki/RepRapDiscount_Smart_Controller

you can choose to fix the lcd panel with 4 small screw

there is a knob to drive the software and an reset button, no need for screw driver to resset it

a slot is made for the sd card for automous printing on the left side of the box

the right side will have the sub d plug and power plug for the hot end an hot bed

sud D plug 37 pinfemae part on the box

I'll post the stl when the system will be completed, i'm waiting for the 31 pin sub d for the output to the motor/end switch/thermistor/fan and the power plug to the hot end and hot bed.

the ramps is cooled by the air flux to the power supply, no need for another fan. it's designed for a 150*141 mm PC power box 480W

I will post some pict as soon as the system is finshed

Quick question, how does this actually function if it needs to be glued together? Surely that's not great for RAMPs in terms of accessing everything - printed everything apart from one side (currently printing that now) and only just realised I need to stick it together.... d'oh!

I printed the LCD panel today on the MendelMax 1.5 I have just put together for / with a mate. The hole for the LCD isn't quite the same size or quite in the right place for my particular version of the SmartController (with the purple pcb) but I have no experience or idea how (or if) I could change it from just the .stl file?

I just installed Blender, have the .stl imported but and completely overwhelmed with all the options (I'm a hardware support guy, not a designer ) and I can't seem to do much with it in MeshMagic 3D.

I'd be happy to supply the desired adjustments if anyone would care to help and maybe it could be offered here as a variant?

Cheers ...

use sketchup(it's free) with the stl export plugin to modify the part.
there ise the sketchup file with the stl file to download

Hi and thanks for the prompt reply. ;-)

I have now installed Sketchup and opened your object(s) but at the first / quick go I don't find the movement tools very intuitive (unlike say Repetier-Host).

I have 'hidden' all but the LCD panel and think I just want to rotate it to a simple 2D plan view to then be able to move(?) the screen aperture a couple of mm to the left and a couple of mm up.

I'll play with it more when I'm in a patient mood. As I said, I'm really only a hardware / electronics support guy and not really experienced in 'software' or 'graphics / design'.

Anyway, thanks again for both the box and reply ... I'm sure if I can't modify it to my needs with SketchUp I will be able to with a flat file. ;-)

Edit: With another play with SketchUp I've found that you don't actually need or possibly want a 2D view if you just want to drag an edge about. On closer inspection I have found the rotary encoder isn't soldered in the middle of where it should be (so is miss-locating the front panel slightly) so I'll correct that before mounting the SmartController to the back of the front panel and then taking measurements for the aperture location. ;-)

Can we get some screw holes instead of glueing it together? Just finishing the last piece tonight and will attempt to drill the existing structures and see how well they hold tomorrow.

Just out of interest, did your little push button fit in the hole as printed or did you need to tweek it to make it fit?

I ask because assuming all things are equal (and in real life they rarely are of course ) if yours fitted as it came off of the printer then so should mine (it doesn't, it seems too big in diameter).

If yours did, then I guess that means we may have some incorrect settings somewhere? When we printed the 20mm test cube it came up at 19.97mm (across all faces) and the second time (after some adjustments), pretty close to 20 so I don't think it's a printer scaling thing?

We printed the front panel from the SD card using Marlin / RAMPS at 200 DegC using PLA through a .4mm nozzle on a 60 Deg heated bed (and it was nicely stuck till it cooled down and the panel is very flat etc).

This is still all very new to us so loads to learn! ;-)

i did it in abs so a drop of acetone is enough to glue it, it is very easy. to use screws you need to add some bits of plastic to drill.

I modified it to use a power supply under my prusa. This made room for an mdf bottom with a raspberry pi mounted. now all of my electronics fit in one box.

I really like the vertical mounting of the RAMPS - this should make for much better convection cooling!

Nice job.
