It looked interesting until I translated the model #. To me it looks like it is 512 counts per turn for 8 turns. No where near the implied 4096 counts for up to 4096 turns. Hubert On 12/19/16 11:30 AM, andy pugh wrote: > These look like something of a bargain: > http://www.ebay.com/itm/New-B

Indeed they do, if I could only find a need for them. Garage is full, already quite much in the cellar and a barn quite full of stuff and maybe in a few other places. On Mon, 19 Dec 2016 17:30:30 + andy pugh wrote: > These look like something of a bargain: > http://www.ebay.com/itm/New-B

Hi Group! Is there any possibility for EMC to use absolute encoders, so instead of homing at startup you load the actual positions from the servodrives? The drive documentation says: "The NC-control system which is connected must have a SSI input and be able to process SSI data in 25-bit format."

Gentlemen, Just a thought on single axis multi motor homing. If the homing sequence would inhibit the axis reaching the index until both have reach index then homing would be as trivial as single axis single motor. thanks Stuart On Sat, Feb 7, 2009 at 4:45 AM, Lars Levin wrote: > Hi all! > > I

Hi all! I have been monitoring this list for several yoars and also been planning my milling machine for too long, but I do have an old milling machine converted and up and running with EMC2 step/dir. My new machine will require two motors on each axis, XXYYZZ A and B This will be a 3 axis port
