Thank you so much for the timely responses. I did think about the repercussions of using the switch I had. It is a switch with both options (NC/NO simultaneously) however I am using the NC side to depower the spindle when pressed and the other side triggers the mach to stop. The nc side of the switch also shows 110v so I didnt want it to connect with the board. I am going to install a toggle switch on the spindle also to allow safe tool changes without interuption of the gcode. If this is all possible. I believe it is. I will test the debounce setting in an hour or so, would that have an effect even if the switch was never touched? It seemed to do it regardless when/once I powered up the box. Seems to work great prior to powering up. It does sound like an induction/interferernce problem or my limited understanding of it. Not being a machinist/electronics/computer/cad student or tradeperson (I do have quite a bit of low voltage experience, media systems and window covering automation) it has been funny when you realize the vocabulary in all of the technical jargon and what it finally starts to mean after endless nights of reading in many fields. I spent so much time testing my HCNC pro board and mach software trying to get the steppers to jog that by the time they jogged, I understood so much more about the software. All of those problems were because I used a defective ribbon cable between the board and the chassis jack I insisted on using. A little anal about appearance. Why else would we be interested in any of this otherwise? I have a problem gettiing absorbed deeply and not sleeping/eating acknowledging anything else til completion. I thought it was exciting, that is why I commit. Sorry for the life story and Thanks again for the responses. I do notice you help many people here as I have been reading as a guest for quite a while.
