It works, it works consistently, but there was much changed and adapted to get to this point. For myself and for anyone else on so perilous a path I thought I should document what finally worked to get this PITA to work. I'm going to spend 2011 working to produce as many repraps as I can, many of the problems I've had over the last year could have been solved much quicker by having a second machine. I have to figure out where I'll be selling the ones I don't keep, for the time being it's likely to be eBay.
|the heap that finally worked|
heater board (PWM Driver 1.1)
Dc driver board
arduino proto shield, sorry don't remember from where
Old computer Power Supply, to replace the 18v PS
washer flywheels, I needed a fly wheel on either end of the X axis threaded rod. This though I'm finding is making the X-axis inaccurate because the threaded rod overturns.
Blue Painter's tape on wood base, the original plexiglass build plate warped terribly. But presently I'm printing on a plexiglas plate on top of my heated bed, which is off... as it doesn't get warm enough for ABS
IDE Cable; I found splitting some old ide cables where needed made for cleaner wiring
5W-30 motor oil, I needed oil... I had it on hand, probably not the BEST idea
2 - 3 thermistors, yea I broke a few when making and remaking extruder nozzles
Feet of nichrome wire, well I kept it and ended up using it to make a heated bed
many feet of Kapton tape, but I still have more
patience... I totally lost it a few times
pounds of ABS... it's all in a box, hopefully I can recycle it some how in the future. Or I'll throw it out when the box is full
I managed to print Wade's Extruder and have been using that with much MUCH success. The Makerbot MK4 / Dc Driver board have been relegated to backup status.
The path forward:
I've been working on printing a Prusa Mendel out of ABS, most of the printed parts are done. Some of the parts are being adapted right now to replace the Z and X axis on my present machine. I want to replace the threaded rod X-axis, which means I have to replace the Z-axis. That is coming in the next couple days and weeks. I bought some black PLA from Ultimachine a week or so ago, I'm going to try switching to PLA for a while starting later today.
I've been thinking about a modified Makerbot I might make make in the course of the year... more about this at another time.
I had been keeping extensive notes on my computer before Christmas, I'll post those as soon as I edit them for readability. Going foward I'll be keeping my daily notes on this blog, seems like a good use of this space.
