Beginner configuration of Chinese red board TB6560 3 axis breakout

So I tried this and came up with some interesting results. This worked, but not on the stepper motors I intended to use.

The steppers I got working have a 50 ohm winding, 6 wire, and I am leaving the center taps of the windings open. They are pinned out differently, where pins 1 and 3 are one winding, and 4 and 6 is the second winding.

The steppers I initially tried are also 6 wire, but only about 4-5 ohms. Much higher current draw, and are the generic 3d printer nema 17 that I have been using for a year or so. They are more powerful and smoother, but would not run. These also have the center taps of the windings left disconnected, and have coil pairs at pin 1 and 4, and 3 and 6.

Both are nema 17's, and when testing I am indeed flipping the two center wires when switching test motors.

At this point I am successfully moving the machine, but only with the spare older motors.

I'm pretty confused now. Is it still a timing issue? Are the steppers pulling too much current from the drivers? I am feeding the board 12.5 volts at a max of 3.5 amps on my power supply, but it's not taking that much current. Not even close.

What do you mean by "flipping the two center wires"?
Those should not be connected in any way to anything.

I just wrote a long paragraph describing the motor differences and right before I posted I got the meter out and double checked and..... yup, I was wrong. 

I've had this machine for a year, but never messed with the wiring, I just assumed (there's the key word right there) that they were the same steppers as the steppers I bought for my CoreXY printer, as I had no reason to believe they were different, and I /thought/ they were wired the same based on wire arrangements of the original setup. 

Turns out that the old motors and the machine motors are the same pinout-wise, but I just hooked up the original ones with the center wired flipped (which WOULD be correct with the most recent motors I bought...)

Anyways, all seems to be working okay now. I'm still getting errors due to latency when starting linuxcnc, but it seems to be working fine right now. I'm now testing timings and getting everything sorted. Thank you all for your help! I very much appreciate it!

Yeah, it has become a headache to always check wiring on 3D printer motors as Creality in a moment of infinite wisdom thought changing the standard pinout is fun as more people would have to buy their drives after blowing them up when trying to use motors with standard pinout on their 3D printers.
And sure enough, other china copycats followed suit.

Is that what ended up happening? I ordered some no-name 5 pack.

I had great luck with Stepper Online before, should have stuck with them. They seem to be on the better end of the chinese offerings.
