The PC board have been mounted to an aluminum plate (provided by Kelly). I picked up some 4-40x1/2" flat head allen screws.
This took far longer than anticipated because I had to sand down the spacers as the screws were the longest in stock at Fastenal I was nearest and the others won't be in till Monday.
If someone wants to tackle hooking up the fan, heater, and thermocouple, please do so. Leave at least an extra 6-8" coiled for the print head. To get full travel on the Z-axis, we're going to have to modify things. There seems to have been some disconnect between design and execution on the Z-axis modifications.
I'll try and tackle wiring up the stepper on the existing plugin cable, and leaving pins leftover for the stepper driver to feed the head. Could someone leave a sketch of the pinout on the 6 pin header on the machine if they're in?
