General Mach Discussion / Re: Upgrade Failed
« on: November 24, 2009, 03:53:17 PM »
Rich,
     I don't have the "disable spindle relays" checked. Under "motor control" the "use spindle motor output" and "Step/Dir Motor" boxes are checked. I read the applicable section in your write-up but I still didn't understand if I needed to do something different here than I was doing in .029 which does work. I never downloaded the plugin for the Turn diagnostics and so I didn't try it. I've gone back to .029, but I will post in the lathe threading problems section. - Thanks - Terry

It seems that I was prematurely offering advice. I had recently updated to 3.042.029 from 2.42 and ran into and solved the issues that I mentioned above which I thought were the other user's problems. Just today I decided to take the plunge to .032 and I am seeing similar problems myself. I am using a Wabeco lathe that uses the Campbell board and automatic spindle control which has never had an issue in the past. When I updated to .032 my spindle speed dro shows -602 rpm (minus rpm) when commanded to turn at 1000 rpm. A tach shows the spindle is really turning at 1000 rpm. The index pulse is being seen and I'm running spindle feedback and averaging. The driver test is nearly perfect on a 3 GHz machine. Index debounce is at 2. I've gone back and forth between .029 and .032 three times now and always everything is fine with .029 and the problem is always there with .032. Actually, I have to ask the question - has anybody successfully installed and run .032 with MachTurn under automatic spindle speed control? There seems to be a number a reports of problems. - Terry

You might have to uninstall the old driver before re-installing the new driver that comes with the later versions. There were major changes to it. This has to be done in the device manager since Windows sees it as a piece of hardware instead of software. The driver changed sometime after 2.42 and I remember a warning about having to do the uniinstall of the old one before installing the new one, but I wasn't able to find the thread where this was discussed. Someone over on the other forum asked the same question but never got a reply.

This happened to me also. The problem was the debounce value for the index pulse in the general config screen. My had been setting at 2000 for a couple years up through ver 2.42 with no issue. I had no idea what the 2000 referred to, but it was a default and worked with no issue. Somewhere along the way, the definition of the 2000 changed to 2000 x 40usec pulses in the recent releases and this was way too much - totally hid the pulse. The spindle speed dro did weird things and threading was impossible. Changing the debounce value to 2 fixed it. - Terry

Rich,
     Nice job on the threading guide. It will clear up a number of things for us. Could you please enable the Printing function for the document. I would like to make a copy to read while traveling but the current version does not allow it to be printed. Thanks - Terry

General Mach Discussion / CSS question
« on: January 19, 2008, 12:03:42 AM »
I'm trying to figure out the CSS mode for MachTurn and have a few
questions.
I don't normally use the CSS mode but discovered while testing a
postprocessor that I'm writing that I probably don't know how it works.

In metric, is CSS in m/min or mm/min? (ft/min for imperial)

Is the following proper to turn on CSS?

G96 S100 where 100 is the CSS in some units
G48 S3000 M3 where 3000 is the maximum rpm allowed

Is the order of the lines impoirtant?

To turn CSS off:
G97 S3000 where 3000 is an rpm I am willing to set

I've tried to piece this together from some old forum posts, but I'm
not sure how things really ended up. There is nothing in the
documentation  to help.

Thanks in advance
Terry

Newfangled Solutions Mach3 Wizards / Re: V2.75 ready for test
« on: October 22, 2007, 02:57:11 PM »
When trying to run any of the electrical shapes operations, I get an "Error on line 53 - Path not found" . It seems the wizard is looking for a Shape TAP file in the G-code directory that doesn't exist.

General Mach Discussion / Re: Cut Type/Infeed type
« on: April 11, 2007, 12:40:01 PM »
OK, but how do these options relate to the numbers that one enters into the Turn Tab? The defaults are both zero in the default profile. What number do I set in to get a right flank cut, etc. ? The documentation doesn't seem to address this. Thanks - Terry

General Mach Discussion / Cut Type/Infeed type
« on: April 11, 2007, 03:47:15 AM »
In the MachTurn 'Turn' options can someone tell me what the 'cut type' and 'infeed type' numbers mean and are these used by the threading wizards or the G76 that is implemented in mach3?

Thanks,
Terry
