General Mach Discussion / Has anyone retrofitted a 4 axis lathe?

« on: November 17, 2009, 01:36:53 PM »

I have a cincinatti 1410 that I am thinking about retrofitting. It lost its programing in the Fanuc controller and I am not having much luck finding info on how to reprogram it. Called the magcincinati they said they would try to find a manual and that was the last I heard.
So I have been thinking about using a DSPMC/IP to give me analog outs for the existing DC drives and spindle.
Then all I would really need to figure out all the IO and make both the dual turrets work. Then figure out how to tweek a post processor for a 4 axis lathe.
It is no small lathe it weighs over 20K. 30 horse spindle.

What do you guys think? Ripp it apart and make mach control it or try to fix the Fanuc stuff?
They call it an acramatic control but the work is being done by Fanuc.
Thanks

dspMC/IP Motion Controller / What mode to run servo drives in with dspMC/IP

« on: November 16, 2009, 05:12:07 PM »

Hello,
I have retrofitted a couple of machines and have allways let the servo drive do the posistion loop.
I like AB ultra 3000's and they have an encoder output, so wiring it will not be a problem to the dspMC.
What control works best when the dspMC is doing the posistion? Do I run my drives in velocity mode? and I dont think I am exactly sure what velocity mode is, But my drives will do it.
Thanks

General Mach Discussion / PMDX 122/106 mach setup?

« on: June 09, 2009, 09:04:58 PM »

Hello,
I have a SmoothStepper, PMDX 122 BOB and a 106 spindle board. The board has the remote pannel interface and the spindle starts both directions and the POT controlls the speed just fine.
The 122 also drives my axis motors fine and works good. However I can not get Mach to send a PMW or start the spindle.
I have read the manual and checked my wirring multiple times and tried every setting I can think of in mach.
I am using the step as 16 and the dir as 14 and PMW is selected for spindle options, I am using pully 4 set-up 0-4000 RPM.
I have the charge pump options on the board selected and have it set-up as Pin 17
I am sure the VFD is wired correct and the board drives it fine in manual.
Is there something I am missing?
Thanks

Can mach 3 do 5 axis machining?
I have been reading about the Centroid controls and the 5 axis tool length calculations can mach 3 do all that also?
Thanks

Show"N"Tell ( Your Machines) / Hitachi seiki VK-55 retrofit advice?

« on: May 05, 2008, 12:36:23 PM »

Hello,
I just purchased a basket case VMC.
It needs alot of work and I am looking at 10K just to get the controls going agian.
This would be the 1997 seicos control, and who knows when it will be smoked again.
Would it be a good idea to try and retrofit something like this with mach 3?
The only thing I can see causing a problem would be controling the spindle drive, it looks like the OEM control uses a digital bus for all the drives.

Here is a link to it on ebay:

Let me know thanks.

General Mach Discussion / Mach 3 and ATC's ?

« on: April 10, 2008, 12:55:55 PM »

Hello,
I have retrofitted a couple of machines with mach 3 and I am thinking of trying my Matsura MC-500V. It has a 16 posistion tool changer I was wondering what is involved with making this work correctly. Would you use a PLC to change the tool and talk to Mach with modbus?
Thanks
