Morning all; Several threads of late about Knee mill CNC Retofits. From steppers to servos... I/o and motion control boards! Tis Overwhelming stuff at times. Harry and myself seem to have ongoing retrofit's in mind. (other thread w/ Jim D here: http://www.hobby-machinist.com/show...ant-to-convert-Anilam-Crusader-M-to-Linux-CNC ) With Jim D providing a lot of info related to his Mill upgrade w/ Servos and closed loop Stepper setups, motion control cards and vendors. It's enough to make me get rather caught up in it all. (in a good way!) Jim's outstanding work write up here: http://www.dawsoncontrols.com/millupgrade.html
What I can say is that if I'm looking to make this thing run forever (yeah, forever LOL) and I need to make it right the fist time ! Looking to come up to the plate ready to smack the ball! (hehe.. pointing to right field here... ) That said, even w/ a 30year IT background and a EE side from way back, I'm still really confused about how all these feedback loops and Motion control systems must integrate together seamlessly. I really need more time to read all this lit but alas there is never enough time so I look here and on sites for "trusting" solutions. Some notes on Jim threads w/ Harry suggest some OTS mixed OEM setups do NOT always play nice. Thus caveat emptor! That said, I am sort of typing this all out to convince myself to order the Centroid kit w/ reuse of my current Motors and drives ( I hope). A slick website or you-tube Vid simply is not enough these days. What I know factually is that once I / we( as we all do this) dig in, read, research and make informed decisions things pan out pretty darn good usually. I have called the Vendors and asking for references to call. What's a quick 5mins phone call on a 3K spend?
Today I'm looking for some info on Mag scales like Jim D. setup. The integration of LM10 and Mag-scales. There is also a new announcement from one Co. about the LM10 Mag-scale comms intrgration to Fanuc! (Not that I know how to do that even!) link here: http://www.renishaw.com/en/all-the-...rs-now-with-fanuc-serial-communications--7939
For my morning "wonderment" and HM lesson: On the Mill that is not even in the shop yet w/ a probable Centroit retofit not yet ordered- What do I connect the LM10 scales output to for a DRO? Something to count pulses, a calibration routine, etc. Can it tie into the closed loop somehow? Just curious here. Not finding much on LM10 Scale w/ DRO or PC based DRO readouts unless you buy a $$$ setup. Will post info back threads w/ Vendor and integration info for reference as I can.
Enjoy the coming Holidays everyone.
