Boy, you must be a student in some kind of technology class. Is this an actual classroom type class or home study? I ask this to see if you have any access to real test equipment or are you working...

I'm not sure how you are getting all the numbers you are stating, but I get the idea that you do not have a good understanding of the math involved. Here are some fundamental concepts:

Your stepper motor should have two coils. A simple VOM (Volt Ohm Meter), set to the resistance scale (Ohms) will show which wires are connected to the same coil. Check for continuity (0 Ohms) between...

Something definitely does not make sense here. As others have stated and implied, a 10us pulse length could not be seen after the frequency exceeds 100Khz because the length of one cycle at that...

I have to agree that a diamond wheel should not be used on HSS, at least if there is any appreciable speed of that grinding wheel. As I understand it, the heat can literally cause the diamond to be...

Connectors can be changed, just like bolts and nuts. If you want to use the DE-9 style connector, they are available with crimp-on pins so no soldering is needed. Do get a proper crimp tool, not a...

Oh boy, much ado about nothing.

I do it. I do it when I need to. I do it with large bits. I only do it with small bits if I really have to. I recently took part in a similar discussion on...

Again assuming we are talking about ribbon cable, yes the red or marked wire is ususlly pin #1. If the rainbow ribbon, then it does follow resistor color code and a brown wire on one side of the...
