Get a video of it running, moving everything. Then when you sell off the parts you won't be keeping you'll be able to get a better price. From: Dan Bloomquist To: Enhanced Machine Controller (EMC) Sent: Wednesday, February 1, 2017 8:01 PM Subject: Re: [Emc-users] Eagle

Hi Peter, And now I can see the summing is done right with the input. You guys knew what it should be and I just could not connect the dots. Thanks to you and Andy for sticking with me. Now it all makes sense. I just found this, don't know why it did not show in all my previous searches:

Re: [Emc-users] Eagle mill retro fit

Well, when I thought this was going to go smoothly, I've run into mysteries. At my age you'd think I know better than to assume. I was working out the details of the current wiring to the Anilam. First surprise, there is no motor tach to the servo amplifiers. They use none of the PID circuitry

Re: [Emc-users] Eagle mill retro fit

Ok. So I talked to the tech at Mesa today and we came up with the 7i92M and 7i77. They plug directly together, no cable and there is plenty of i/o on the 77 for this mill and anything else that may come up. I've ordered the boards. Best, Dan. --

Re: [Emc-users] Eagle mill retro fit

Hi John, all. Sorry, when I re'd it was just to John instead of the group. So... I'm back at it. I posted here about a year ago, in this thread. I finally got a scope on the wires for my mill. The glass output is 5v digital quad output. Looks very close to 5um per step, so I'm going with that.

Re: [Emc-users] Eagle mill retro fit

I managed to get the Anilam chief engineer on the phone one day not long after purchasing the BP and he walked me through the tuning process of the drives. I'll take a look to see if I have the same cards as you or not. For the drives part you need the analog velocity pins and the enable pin. O

Re: [Emc-users] Eagle mill retro fit

I'm not sure how close the 1400 is to my 1100M but in the right cabinet is there 3 boards with a connector on top and one on the bottom of each board? http://gnipsel.com/images/bp-knee-mill/bpel01.jpg That's all that's left in my cabinet is the drives and power supply. JT On 2/7/2016 11:06 AM
