I'm seeing the exact same thing. What chip did you resolder pin 2 on?by StickyC - General Mendel Topics
For what it's worth, I had the exact same problem (this post was the first hit on a google search for the error). Likewise running Win7 64bit, 64bit JRE update 23, and RepRap 64bit 20100719. Switching to 32bit JRE u23 and RepRap 32bit solved the debug output issue for me.by StickyC - General

Couldn't you use PWM/Analog voltage control to the electromagnets to control the position of the bed magnets exactly at any point between pairs? It'd be an active feedback loop, constantly adjusting the "power" of all of the electromagnets to slide the bed in one direction or the other. The magnets/electromagnets wouldn't have a 1:1 alignment. Sort of like this: Google Docs Drawingby StickyC - Mechanics
Just thinking with the fingers here - Would it be feasible to hand-craft electromagnetically linear actuated beds for the X and Z planes? I'm visualizing a batch of rare-earth magnets glued to the underside of the platform and some hand-wound electromagnets mounted to the bottom frames for each axis. I'd think with some sort of high-resolution optical positioning system (cannibalized from a pby StickyC - Mechanics
I'll be there as an attendee only. I'm still working on my first RepStrap and will probably have quite a few questions for those who're farther down the path than I. Absolutely looking forward to meeting some of you people in person!by StickyC - General

Wow! Thanks for this! I'm just getting into the meat of my McWire build and am running into pretty much everything mentioned so far. Also helpful was actually looking at the flickr stream that includes the photos on the current web page, there's a lots of pics that weren't included that cleared up confusion for me. I'm still unclear on the drilling templates for the other ends of the U rails. Iby StickyC - General
Chris in San Jose - Just getting into RepRap (and the Arduino). Starting to build an McWire, electronics first (since they're more universal and I dont have a source for the cut plastics or a drill press quite yet). Just started earlier this evening building the opto-stops. Is anyone a Techshop member/certified on their laser cutter or CNC mill?by StickyC - California, San Francisco Bay Area RUG
