I bought a ATX-power supply, cause I was under the impression that the mendel got it´s power from that, but I can´t find any such info so I guess thats how the makerbot does it. The mendel needs 12V for the stepper boards but the main board gets power from the USB-TTL wire, as far as I can understand. I think the Extruder controller draws power from the main board. There´s also a USB-connector I can´t seem to find much info about. However I guess i can always hack the ATX-P-supply to power the stepper boards.
Tried to assemble the x-axis onto the frame and discovered that one of my leadscrews were anything but straight. The ones I got now are plain studding, I guess I´ll cut new ones from stainless steel since that is supposed to be a bit straighter and better.
Frame after putting the x-axis on, getting annoyed at how hard the right leadscrew was to turn, partly disassembling the x-axis and realizing the leadscrew was horribly bent.
Here´s the bugger, If it looks like its real crooked it´s cause it is.
