Got any info on the drives? There are a few step to analog converters out there (not sure of the current models) or, of the drives can be configured for step/direction operation. Don't care about the CNC control, just the drives.

Not sure of the model of the drives but they are DC for what that's worth. About 1988 vintage.

I downloaded 3.042.040 and backed up my XML and loaded it over the old version. Did the reboot and tried it again, and same problem. Bummer. I looked at the device manager and it was the new driver, so don't know what to do now. I am heading to Cleveland tomorrow to pick up my Lagun CNC  mill so I won't be on here for a day, will be back at it after that. Thanks Hood.

I deleted the driver and then reloaded 3.042 from the same download I had, rebooted and have the same thing now. I had downloaded that version of 3.42 quite awhile ago, just hadn't gotten around to updating it until now. One thing, when I power up the power supply and then hit the e stop off the machine does it's typical "Bonk" like it has powered the steppers, but I tried turning the Z axis ballscrew and I can, so it doesen't actually have the steppers in hold, which sort of makes sense I guess.

So, if I download version 3.042 again, will it have the right driver in the installer, or how does that work?

Thanks, Dave.

Sorry was forgetting the Turn screen probably doesnt show the frequency, you could load a mill screen for viewing purposes. Also see what Time in Int is.
The driver version should be seen if you go to device manager and expand  the pulsing engine then right click and properties for the driver, on the driver tab you will see the date and version of the driver.

Looking in the device driver, date is 9/21/2008, version is 5.0.1.0 and shows no problems there. I checked the ports and pins and they are correct for my Sound logic breakout board. Tried another screen but it didnt make any difference. Diagnostic page shows nothing lit up except the index signal. Time in int. moves from 5.4 to 8.8 approx. Bummer.

What would the name of the driver be, and in what folder? I don't seem to have or be able to find a frequency on the diagnostics page. Only thing, it is showing as running at 35Khtz, and I sort of recall it being set at 25Khtz before. I think I will have to go check the ports and pins and confirm that it is correct. Thanks guys.

Yes, lathe has worked flawlessly for 3 years, apart from the threading pitch problem. And that wasn't even a problem as I usually make both male and female threads for the mating parts. Have attached my original XML. Thanks.

I bought a used Lagun mill with an Allen Bradley 8400 control. I haven't actually gotten the thing yet but am wondering if the control is no good, will Mach work with the drives it might have? Will know more about it on Thursday. Thanks.

Well I finally did the upgrade from 1.84 turn to 3.042. I backed up my XML and ran the instal file, and then rebooted. After I started it up again and got the silverblue screen set installed I tried to home the machine. When I power up the system and then click the E stop screen button off the lathe makes the fimilar noise of the steppers going into power and holding so I know that there is something right. All the tools and things were still there, all looks good. My problem is that the steppers don't actually move. The readouts show they are but I have no movement. I am not honestly sure of what ports and pins should be what, it's been years since I did anything real as far as maintainence to the thing, and because the steppers go into hold I think I have stuff right there, but no movement. I have attached my XML so anyone can loook and maybe let me know what's wrong? thanks.
