Hey VDX That is a very very nice setup, had no idea you can use normal steppers, kinda obvious when you think about it...which I didn't. What are you using for mirrors? My interest is a very large 1M...

Hey guys! So I just finished building my DIY TAZ, and it's printing well. But homing isn't working that well. The when homing, it often stops short of the endstops (on all axes). I suspect cross talk...

First of all you should probably check that there really *is* 'cross talk' - perhaps by attaching one of the cheap chinese logic analyzers to your system. Depending on your setup a pull up / pull down...

I'll double check to make sure the internal pullups are on (I'm pretty sure they are). I think I've got a logic analyzer laying around somewhere, so I'll see if I can find it. As far as adding a...

I am not sure if this helps. However cat 5e cable is very good at removing cross talk for anything high frequency. I am using it for my mechanical end stops. So far my printer homes just fine. However...

I was actually thinking about using cat5 if I had to rewire them (which I think I'll go ahead and do). I sure wish I had thought about that when I did the wiring the first time! It's going to be a...

I just went ahead and pulled apart the wiring and used a drill to quickly twist each pair of endstop wires (didn't bother with the stepper wires). It seems to be working fine now, even with the...

Unshielded twisted pair I read that you should use clockwise and counter-clockwise twisting between pairs, and different twist ratios between pairs within a common sheath.

Having your signal wires in a different sheath from the motor wires can help since the motors are a big source of spikes. In theory, twisting the motor wires could help also. If you do twist the motor...
