CSMIO/IP-M and PM752 Drivers

[Washout]

Something doesn't sound right there.? Or is it just bad sound.?

Not sure - the sound is generally bad on the camera and its also mounted directly to the spindle/bearing mount. The spindle is fairly new and does make a bit more sound than the one I had previously, but it doesn't get hot or anything, so I assume its OK (pulls about 1.8 to 2.1 amps under load). The hole is also drilling through the stock into the sacrificial bed for indexing purposes and the drill will be catching on one peck at lest on the double sided tape under there (plus some other detritus in previous cut throughs).

Just about to head down to the workshop to try the pulse edge thing, but I also notice in my drive manual/datasheet that there are 4 jumper settings to choose from:



I'm assuming that "a" is default, so I probably need "b" (or vice versa depending on what I find in there and assuming I don't set it in MACH4)?
