I have an axis with 50800 counts per inch. This gives me the proper amount of travel but in the wrong direction- I am only turning the screw by hand When I use a negative 50800 it is correct. Will this cause me any problems or should I flip the A and B around? changing the sign of

Silicone-based insulation is very good from a temperature perspective, though they are typically more expensive and mechanically weaker than PVC isolation. It's pretty nice to work with though, as it's very easy to strip and very flexible. On Wed, Jul 9, 2008 at 12:38 AM, Emory Smith [EMAIL

The classic wire wrap wire has kevlar insulation, and I believe that it handles heat pretty well. Teflon insulated wire does well, also, but it is a pain to strip without the proper tool. Ken Kirk Wallace wrote: I have been using CAT-5 wire to solder up perfboard circuits, but the

[Emc-users] independent stepper driver

Hi, I have a question for you electronics experts out there.. I have added a little lathe to my mini-mill which I want to act both as an 'A' axis or an independent lathe. So, I would like to use the same stepper to drive the spindle in both cases. As it stands at the moment I have a
