Looking at the pre-drilled specs on the PBC site, it looks like even on the (largest) 60mm rail, the pre-drilled holes would be off by 0.5mm (if using standard 2040 aluminum extrusion). 2040 requires a hole centered 10mm down, but the options for PBC are 4mm (20mm rail), 5.6mm (30mm rail) , 8mm (45m...
Indeed, there seemed to be some confusion about my initial post. I figured since I was posting in the Gecko section, not much more detail was necessary, but in retrospect maybe I should've been more explicit. That's good feedback, cvoinescu, and largely the conclusion that I came to myself. I had pr...
Has anyone had any luck using independent homing switches on a dual-Y axis to square the gantry? I've been doing research and come across a lot of references to gantrykins and stepper-gantry configs, but I can't seem to make heads or tails of how to set up the system so that it can square my Ys usin...
Given that the resistors allow the controller to reduce the current to motors rated at less than 3.5A, would it be reasonable to assume that 2 nema 17s rated @ 1.7A could run in parallel off a single controller without a resistor?
Yep. I've posted in the past about using a TB6560, which I burned out, then replaced with a TB6600, which lasted a good while - but also burned out. At this point, I've just said to hell with it and bought a G540. No questions as such. Just very happy with it.

One caution about these boards with the aluminum enclosure. In my case, (TB6600, but same thing, really) the enclosure was set up to act as a heat sink. However, it's not working very efficiently. After about 20 minutes of activity, the X axis started losing steps. Simply hooking up a fan solved thi...

I tried using a 6560 3 axis board when I started, but I burned it out within a few hours. Since then I've switched to a TB6600 based board and have been going strong. Only issue is that the aluminum case it came with didn't do much to act as a heat sink, which was causing my x axis to lock up, so I ...
Yeah, I have to agree akhlut. Shipping was expensive, and I had a few hiccups with my order (still waiting on confirmation of final resolution), but this was still a pretty good deal.
