Huxley Fold Panelolu Mod
Description
May work on normal Huxley but you will loose some height.
Hardware required:
ThinkPrint3D Panelolu kit
3 Off 16mm M3 screws
2 Off 20mm M3 screws
1 Off 30mm M3 screw
1 Off M6 Nyloc nut.
Instructions
Assemble electronics using excellent ThinkPrint3D instructions (but using vero board assemble pots, encoder and reset switch arranged to fit this panel).

The ribon cable I split every second core to allow it to neatly hide in the cable spiral rap.
IMPORTANT NOTE, you will have to free pin 10 by using the standard sanguinololu pin 12 heated bed control, i just soldered the Huxley heated bed mosfet control wire to the pin 12 track on the bottom of the Sanguinololu pcb.
I have included my Huxley Marlin File because I struggled to get it to work with stock ReprapPro gthub Marlin files (think they still developing it), be ware I use 18 tooth T2.5 pulleys and the axis may be wrong way round as I like the cable colours always the same so change firmware to suit.

HI,
On Huxley #710 the heated bed is driven from A2, whilst the potential for bed leveling detection is supported via a connection to D10 by default.
How did you decide to connect these, as I can't see them being connected from the panel to the heated bed?
Hi Conseils, sorry been busy with Xmas, in reply, never connected the leveling detection and disabled in firmware pins.h, also the bed mosfet control wire I connected directly to the Sanguinololu R11 HOTBED signal mosfet side.
Just another note the reason why I included the full Marlin file is that the original marlin files from git hub were using tables and I found inaccurate at 200degC, whilst reprappro's marlin files include the calculated temperatures that suit the Huxley kit, so I mashed the two by copying the panel files over the reprappro panel files
Hope this helps

Hi natko,
I've been wanting to add a panelolu to my fold-a-hux but have been waiting for it to come in. It finally has, but I am yet to attach due to some questions about the wiring and such. Can you provide a picture of the inside of the case you have made? If using the panelolu without an SD reader (as the Melzi has one installed already) then there is no need to modify the Mosfet connection that is made, right?
Thanks as always. I've really enjoyed assembling my printers with your help.
Cheers,
Ben
Alas, I think I may have answered my own question with further research. I may need the MCP23017 port expander, if I'm not mistaken, to make it work with the Melzi. I'll post an update once I know for sure.
