Hi, i am in the process of machining a slotted disc for the spindle for pwm signals for  my cnc lathe retrofit but am unclear if the latest versions of Mach 3 support multiple slots plus a wider index  slot. I have read that  you can now only use  one slot so can somebody who really knows please clarify this as i would prefer to use multiple slots for greater accuracy if possible.

Many thanks
Charlie

Single slot and multi slot was found not to be of advantage.

Thanks Rich, single slot it is then.

I use a Halls affect sensor instead of a slotted disc. Easier than trying to mount a slotted disc.
FWIW,
RICH

Also would suggest not to use the lockdown or Dev versions as they have issues, especially with Turn. I would suggest you go to the ftp site and download an earlier version. I use 057 but others seem to like 062.

Thank you Hood, will bear that in mind.
