Re: [Emc-developers] I wish I had a super size 8i20
Thank you, sir. I'm in process of doing an Emco pc turn 55 for myself and first order at the school is a prolight conversion... along with freshening up some old microkinetics hunks of junk that I'd rather not talk about . I was thinking of keeping it fairly simple with the one at the school. DMM servos, 7i76e, see if I could reuse the old spindle drive somehow. Considering the shape the old girl is in now, anything would be an upgrade. Mechanically, it's still very sound but the operator panel looks like she came out of a back alley on an episode of Cops. The school board ordered a new Haas for the machining class (*cries in DMG Mori*), but I want the engineering students to get a taste of real world instead of just poking at a plc pegboard with a traffic light attached to it. The educational power of Linuxcnc alone is worth its weight. Admittedly, I'm just a lurker on the dev email as the only "programming" experience I have, besides 25 years of G code, is with Fanuc, Mitsubishi and Siemens macro logic (I'm still a proponent of goto statements in macro, btw ) , but LinuxCNC has inspired me to do so many new things, like learn plc circuitry and just the other day, crack open my old book on C programming. I'm an AE for DMG Mori, but never got into the electrical side of things until just recent, all because of the power of Linuxcnc. I can't thank all of you guys enough for your contribution to this. I hope my YouTube tutorials and contributions at my school help bring in a lot of eager new users and developers to the project.

Re: [Emc-developers] I wish I had a super size 8i20
I'd be happy to show how the conversion goes. I need to do a writeup on the lathe I just finished too. I have yaskawa encoder modules written for mesa and hostmot2 drivers for those in linuxcnc. I'm getting ready to publish them soon. The machine is being delivered next weekend so I haven't gotten to tear into it yet. From what I can tell it may have the same bolt pattern as the 900W yaskawa servos that I used on the lathe. If so I'll be using them. Those yaskawas perform so very well with the 8i20 and 2097152 count encoders. On Sat, Feb 27, 2021 at 12:27 PM Feral Engineer wrote: > Curt, > > Can you please document your progress with the Fadal?

Re: [Emc-developers] I wish I had a super size 8i20
Curt, Can you please document your progress with the Fadal? There's one at my old school I want to dig into eventually with some of the students. It's also a VMC 15. Thanks!

[Emc-developers] I wish I had a super size 8i20
I've recently purchased a Fadal VMC 15 and I'll be retrofitting it and replacing servos and electronics. The last machine I retrofitted was an old miyano gang lathe and I'm driving the spindle and servos with 8i20's. I just love them they are great. Is there any plan for a larger capacity 8i20? I wish I didnt have to buy vfd's for large spindles and could use a super size 8i20. say up to 10hp or so. Has this ever been discussed before? -Curt ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
