First things first: many thanks to my build buddy, Tony, for providing me with parts printed on his Prusa at no cost (he wouldn't even let me pay for filament). Without his kind assistance, I'd be buying printed parts, and that would drive up the cost of my build tremendously. I suppose this means that the next round of printed parts will be on me after I get the Max up and running. Believe me, I'll be more than happy to print for Tony or for the next friend of ours who wants to join us in the adventure that 3D printing has become.
The latest addition to my inventory are the four vertices for the upper frame members to attach to the lower frame. With these in hand, at least the frame can take shape, and my experiment on the upper cross members can commence.
That will come later (probably this weekend). I just wanted to take the opportunity to say, "Thank you, Tony" for all the parts!
While I'm here, we had the chance to chat briefly at work about the Emergency Stop feature I want to implement on our printers. Tony tells me the Sanguinololu controller can issue the appropriate commands to control an ATX style power supply unit. This means we could also implement a system stop feature in software, too. As of now, our plans still include a hard-wired "hot loop" to stop the motors and extruder when the E-stop is depressed.
I'm thrilled to be moving forward on the build again. It looks like our next move will be the acquisition of the Y-axis slides, then the rest of the motion components (GT2 belts and pulleys, stepper motors, etc.)
Gotta run for now, or I'll be late for work (there's that four-letter word again!)
