General Mach Discussion / Re: M9 doesnt turn off coolant

« on: June 06, 2009, 01:33:51 PM »

no I cannot turn the coolant off from the main page , once on it just continues to run until mach is shut down and restarted or you unplug the pump. will reload and see what happens, m9 worked once then hasnt since

General Mach Discussion / M9 doesnt turn off coolant

« on: June 05, 2009, 10:13:41 PM »

I can turn on coolant with m8 as expected but cannot turn it off via m9, also does not turn off when m30 is called out either.  Should there be an m8 and m9 file in macros? Possibly some setting I have missed?

General Mach Discussion / Re: g95 lathe feed per rev mode?

« on: June 04, 2009, 08:36:26 AM »

thanks hood , It was how the feed rate was handled that I was curious about, was unsure if it went on the g95 line or the line that calls out the move.

Just wishful thinking on g71 , I very much like lathe canned cycles for rapid manual coding , Also makes for short programs on complex cut files generated in Mastercam

General Mach Discussion / g95 lathe feed per rev mode?

« on: June 03, 2009, 10:39:04 PM »

could someone give me an example with quick explanation of using g95 feed per rev mode in mach turn?

Also curios if canned cycle g71 might be usable in the future

Got my issue all ironed out , simply put the SS board inside the computer cabinet at the front of the lathe , wired it to an internal USB on the motherboard , mounted the two DB25 connectors and ran 2qty 12' printer cables back to my BOB at the back of the lathe and it seems to be running like a top.   Dont know why I didnt think to just move the SS into the computer case 4-5 days ago , would have been much easier since i already had the printer cables routed anyway

General Mach Discussion / Re: can mach be set to remember which tool is loaded on shut down?

« on: May 28, 2009, 10:24:55 PM »

it does and it works as expected once its been running and the tool called out is already loaded , but for some reason it still trys to do the tool change even if the tool loaded is the one called out right after mach is started

General Mach Discussion / Re: Help conecting mach3 with Automation Direct servo motors

« on: May 28, 2009, 08:19:10 PM »

The three wires shown in Brians drawing are the only ones that need to be hooked to the break out board that interfaces with mach , the com+ and com- terminals on the sure servo breakout board are used for source or sinking other inputs.  You will need to attach at least an enable and reset push buttons to the sure servo break out board to get it up and running.

They are really nice drives once you wade thru the manual. I found there are only a couple of drawings and maybe 10 pages in the 500 page manual that you need to get the drives set up in Mach. I will look later and post the page # if you would like

its a 30 hp VFD from automation direct. I have a 40 hp rotary phase converter on the wall aprox 5 feet behind the lathe . The power from the phase conv runs into a circuit panel where its distributed , one leg to the vfd on the wall right beside it. The rest of the machine receives its power thru a delta to wye transformer. Off to search for the vfd noise related thread so I can stop cluttering this threading thread up with unrelated post

Thanks Rich , my problems with the SS have been multi fold . I was having USB driver related problems which I eliminated today with a fresh instal of XP pro and new drivers from Dell .

Now that I have eliminated the USB problem I can succesfully turn parts for quite a while until there is a heavy load on the spindle and I get interference .
I can turn , thread and part off small alum parts (sub 2" diameter ) with no problems as long as I dont take heavy cuts , as soon as I take a heavy cut I can hear that audible high pitch from the vfd and thats about the time I loose connection with the SS. As long as the cabinet containing the SS is closed I only loose comm when there is a fair load on the spindle.
If I open the cabinet door which faces the vdf I loose comm instantly .
So now that the USB issue is fixed I am just down to chasing down this interference issue from the VFD. Tommorow I will be encasing all the wires to and from the vfd in metal conduit. Hopefully this will help .
Would it help to put the SS in an enclosure of its own? Its in the main cabinet with the servo drives and BOB, plc etc which is aprox 3' wide x 4' tall. There is an identicaly sized cabinet beside the control cabinet that contains relays , control for the hydraulics and a a few transformers should I try moving the VFD from the shop wall into this cabinet ?  I can move a few transformers around a squeeze it in if it might help?
I am just not sure if the noise issues from the VFD are being emmited from the unit , its wiring or a combination of both.  Should I be looking at isolating the source of the interference or insulating the SS from it .

Ill stop rambling on , just feel I am getting very close to finishing up a year long project . Thanks Richard

General Mach Discussion / Re: Spindle Index RPM not Matching Actual RPMs HELP

I am running the same c3 board on my 9x20 with a 1/4" slot in a 2 3/4" diameter disk and it seems to be working just fine although I have never run it over 1100 rpms.
