@honuvo If you need any help, I have a RepRapPro Fisher, though I have updated to a Duet 2 Maestro and BMG extruder. Prints really nicely now, and quiet! Though currently one of the acrylic side panels is broken, so not using it much.
Original build instructions are hosted by Dr Adrian Bowyer's company, RepRap Ltd., here: https://reprapltd.com/documentation/
They still sell Fisher kits, too, but now with Duet 2 Maestro electronics.
