I've done that too. I've swapped them around, switches active low settings, tried series and parallel wiring arrangements, the only answer I can think of after all the things I've tried is that somehow I've got extremely bad EMI problems, or the breakout board is bad, which could be true seeing as I think I put 12V through one of the inputs when I first tested one of those proximity switch. I didn't have the resistor that the C25 breakout board manual says to use.
UPDATE
I accidentally deleted the good video of the X and Y axes moving, so you'll have to live with this poor example until tomorrow night. Sorry guys.
Here is another photo of the general machine, yet to get the Z, B, or C axis sorted out. These damn machine shops aren't very snappy around here.
The wiring of the stepper motor and limit switch ports. Limit switch wiring (top row) are likely to be redone seeing as they don't work at all how they currently are.
Lots of wires in this machine.
Machine porn (don't mind the messy wires):
Another shot of the control panel, I'm quite pleased with it. The e-stop box is extremely solid, I love the feeling. Raise your hand if you hate having to be gentle when rushing for the e-stop.
Here is a photo of the X axis ballscrew whipping support. The hole that the ballscrew goes through is too sloppy because I was test fitting it on the Z axis ballscrew because that one isn't currently installed, the problem is that the Z axis ballscrew happens to be about 0.6mm bigger. I don't know if 0.6mm oversize is enough to cause them to be completely ineffective, but they are. I even slide them up so the ballscrew is rubbing on them constantly and the ballscrew still builds up a vibration that jams up the entire axis and makes the stepper slip. I can't run it faster than 3700mm/minute, which should be okay for my cutting needs, but the Y axis can do 10,000mm/min, I'd like it if they all matched.
The white bushings are acetal (Delrin), does anyone have some advice to share on remedying ballscrew whipping issues?
I'll be sure to shoot a better video tomorrow night showing the X and Y moving more notably. But for now, enjoy!
