Quick question. On my ESS, MX4660, 2.2kw spindle setup, I have to use a separate clip-on wire ground connection to the spindle to zero the bit. This prevents, as far as I know, the auto-zero of bit changes. I am wondering if I can connect a "MX4660 system ground" to the spindle can I simply probe for the top of the +10 vdc contact and eliminate the clip-on connection? On my PC 690 system, which has a build-in ground, a separate ground wire is not used and it auto-probes at bit changes nicely. The system is well grounded in that any two metal parts have near zero or zero ohms resistance. No problems with electrical noise (thanks Al_the_Man). The question: Is there any danger to connecting the MH4660 ground with the earth ground? This would eleminate the clip on wire for and allow the system to auto-zero after bit change. Thoughts?
Thanks
