Brains Development / Delay Reading DRO's

« on: March 05, 2010, 12:30:24 PM »

I am making a brain to watch spindle rpm and e-stop if the feedback from the VFD is 0 while spindle led is on.

Problem.....When the spindle on command is given, at that point the spindle feedback is 0 for a split second so there is a failure.
Question.....How can I delay the reading of the feedback RPM after the spindle led in on so I can wait so many seconds for the spindle to be at speed, then start checking the RPM feedback to make sure the spindle actually came on?

I have tried for several hours to use a timer to delay the reading, my assumption is that you can't use timers to delay the reading.

Thanks in advance!

VB and the development of wizards / Latest Mach Ver .038 tool change

« on: March 04, 2010, 04:31:13 PM »

Just installed ver .038 and now have tool change problem.

I have manual tool changer so must use Stop Spindle & Wait option in config.

If I have T1 in the spindle and is current tool and read T1M06 how do I get the tool changer to ignore the command to change tool.
I used to check if tool selected = current tool and then issue a DoOEMButton(1000) in the m6start file.
Then it would jump to m6end file and I would issue another DoOEMButton(1000).
Program worked and continued on......

Well now issuing a DoOEMButton(1000) does not work. It starts the cycle timer but nothing happens in the program.

I also tried doing Auto Tool Changer in the config and in the m6start file did a SystemWaitFor(55) or (start) and nothing happens.
So that command doesn't seem to work anymore.

Any Ideas???

The problem seems simple enough....if tool selected = current tool ....do nothing.

Thanks!!
