Re: [Emc-users] Any Interest or Ideas for a Linuxcnc Fest 2016 ?
I'm in Boulder, and would be interested in this. Let's do it! On Jun 15, 2016 8:29 AM, "Moses McKnight" wrote: > I'm definitely interested.

[Emc-users] LinuxCNC for retrofit of Cincinnati Milacron CNC?
I just joined the email list since I'm wondering about using Linux CNC to retrofit the control system on an old Cincinnati/Milacron CNC system. The motor control amplifier for these machines seems to be a Kollmorgen BDS4. Has anyone here created an interface to one of these? Is Linux CNC a decent option for replacing the old control computer on one of these beasts for use in a low volume production environment? -- - Wayde -- Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.

Re: [Emc-users] Stepper Motors/Drives
A number of the motor manufacturers Galil, Kollmorgen, et al have motor sizing information information and tools on their web pages that may be useful. I just had to lookup the Kollmorgen page to make certain that I'd spelled that correctly so here is a link for them. http://www.kollmorgen.com/en-us/service-and-support/technical/technical-support/ OK, here's Galil's: http://www.galil.com/learn/motorsizer I've been working on retrofitting an old dish antenna system, see < https://www.youtube.com/watch?v=HqAmpVnAuzE> with Galil products with good luck. However, just for the record that is not using LinuxCNC. - Wayde On Wed, Jan 13, 2016 at 9:52 AM, Bruce Layne wrote: > I've had good luck with the stepper kits for CNC conversion on eBay, > from Wantai or Wantmotor or Longs Motors.
