Quick update

The last September "Midge Ace Art studio open day" completed back to reprapping again..!

These were the Next Jobs:-

Get Pid or Bang Bang Extruder temprature control part working. Done
Get Pid or Bang Bang Build Base temprature control part working. Done

Make the drawings for Worm drive Extruder stepper.  Done (but took longer than expected!!)
.... drawings stepped up from Extruder MK3 to now Extruder Mk5 seems to be working very well so far.
I was able to hot swap ABS filament 

Make full size Mendel heated Bed with removable print surface as per WIKI . Done

Changes made to Mendel heated Bed 4mm Aluminum, extrude slot drilled out with 32mm drill, 6mm MDF insulation layer, Kapton tape electrical insulation layer nichrome wire heater element as used on my Huxley Fire glass heated bed in February.




Next Jobs

BodgeIt is RepRapping in the Home Office at last!!

After a lot of playing around with Firmware and software I have decided to use the Repsnapper host software with a customized version of the 5D firmware. As I'm using a mixture of hardware on the various repstraps that I have.

So :-

RepstrapMendel is using Motherboard V1.1 with 4  2.3 stepper controllers the original PWM driver V1.1 board.

RepstrapHuxley1 is using Motherboard V1.1 with 3  2.3 stepper 1 Bodgeit micro Stepper & Vero FET Bd

RepstrapHuxley2 is using AudrinoMega with  4  1.2 stepper controllers & Vero FET switching board.

RepstrapDarwin1 is using AudrinoDemiglove with 4  1.2 stepper controller with a Vero FET switching board

RepstrapDarwin2  TBD (I need to make use of 4 extruder controllers that are currently redundant)


I made the two Huxley's way back in February this year when they would have been called mini Mendel's.
Once I finish the easier to make Mrk2 Huxley Strap I will post all the drawings in the WIKI if I learn to drive the WIKI input interface.

I have abandoned the MDF Makerbot build due to RS485 problems on V2.1 Extruder controllers.
I can now build the Makerbot firmware using my Ubunto10.04 machine (Thanks to several hours of work from Midge Ace  in exchange for setting up her Art studio & Conservatory then building her a 4.5m x 4.8m decking for the Cheshire Open Studios event last week and the weekend after next)

However my next most important job is to install the Potbelly stove in the home Office as its beginning to get a bit nippy at night in here.
