It's always safer to use a higher voltage cap than a lower voltage cap. It isn't a fuse... There is only one case where we dropped the voltage on a cap. We were using a tantalum cap that was rated to 16V, but had been built in the standard packagi

Short answer: Yes. Depending on the application of the conductive ink, suppliers select different mesh for the silver particles. So, you should follow your supplier's recommendations for printing, for instance: Conductive Ink||PI-2000 Highly Condu

sorry. re-read your post. The problem is the home sensor relative to the home pulse. You're catching the wrong home pulse. a 10mm offset sounds about right for a 360 degree error. You need 50% +/- 15 % to ensure you always zero to the same phys
