Mine is nearly together! Just need to install the extrusion module and wire the associated connections. Unfortunately my clumsiness cost me one of my microswitches so that won't happen for a couple of days. Everything else is looking good with only a few hiccups. I still need to find a build plate (I tried cutting glass for the first time... fun but I still need to find a build plate haha).
How did you guys determine how much tension was appropriate for the drive belts? I think mine have a nice amount but it's hard to describe... They don't have much slack at all, but they're not so tight as that they might cause the tower caps to creep down over time.
I think the only way I'm really deviating from the original design is that I'm not going to pass the wiring for the extruder/feeder through the extrusion; I'm just going to run it under. Is there any issue with that or was there a specific reason (other than aesthetics) that they pass through the extrusion in the original design?
While I'm here, is there anything I should keep in mind for wiring? From the perspective of looking toward the LCD screen, I've assigned the tower on the left as X, the tower on the right as Y, and the tower at the back (with the extruder stepper) as Z. I think my main concerns are a) have I assigned the right positions for the microswitches (are they connected to the min or max pins?), and b) if I've wired my steppers correctly (everything I've seen seems to indicate that the wires are in the same order leaving the steppers as they are entering the board... for example, looking at the stepper motor connector on the motor, it might go green, red, grey, yellow, and on the RAMPS board they enter the receptacle in that order too).
EDIT: I've tried creating a new set of arms too and these seem much more equal length, so I'll give them a shot. Carbon still seemed to be the way to go for economy reasons.
