When your cutting into epoxy do you by chance generate more static electricity than say wood ?
My reason for asking . Yesterday I was cutting a female pocket into the back of a clock blank I was making . Nothing that I haven’t done many times before . The cut kept failing . 30% done then errors pop up . Restart , 35 % done then disconnect . Reset then 40% done and errors again .
Stepped back and took a break . Threw on a piece of wood . Ran the same tool path . No problem . Ran perfect . Placed the clock blank back in . Ran the tool path . 52% then disconnected. Reset start again 78% errors . Start again 93% disconnected. Reset and got it finally done .
The center of this clock was mostly made up of hardened resin . I noticed the chips seem to be very ( clingy) they ( stick) to everything and appear to be static charged so that’s why I’m thinking that may have been the issue .
Having worked years and years in an antistatic enviroment, where peeps need to wear neatralisi g equipment to even enter a door, I can state that wood is a static neutral material. Plastics are not and are not allowed in an antistatic enviroment.
Epoxy is pretty static and when rubbed against with the speeds you have on a spindle/router, they build up quite a charge that can cause al kind of problems.
@Quebecnewf A long time ago, when I was having static issues, I grounded everything that got in the way. I added a ground strap from the router mount to ground. I can’t say that is solved my issue, as I did other things at the same time, but it may be worth trying.
Grounding the spindle casing, the machine frame can help. Having the substrate resting on a metal plate that is firmly grounded might help reducing static buildup aswell.
Shielding your cable and even putting the controller in a faraday cage can help too.
