Reason I thought of the bad contacts was I  remember a computer I built for a friend and was forever getting called in to take a look at it as there were problems. Of course every time I was there it was fine, next day they would call and say it was playing up again, eventually I figured out the issues as I started asking questions and it seemed it was only an issue first startup and usually in the morning. The place it was in had no heating and eventually I traced the problem to a memory stick which must have just been a few microns thinner than normal and when cold was making intermittent contact in the slot. Popped a new stick in and never a problem again, better still I have that same stick in my old computer and it doesn't have an issue even in my freezing workshop so can only assume that the slot on the other computer was also slightly loose.

Hood,

The wierd thing with mine is, it makes ALL the USB devices squirrelly, not just the SS.  The keyboard and mouse get flaky, and before long the whole machine locks up.  That's why it took so long to track it down to the SS.

Ray, regards your cold weather issues, have you tried a different USB cable? Could be the contacts of it are not great and in cold weather its breaking contact.
 I certainly dont have problems in the cold and believe me it has been cold here lately, down to minus 16 deg C here and even colder inland a bit, even my coolant has been freezing up LOL

Mine was never a problem in the past - worked fine all through last winter.  But this year, even in relatively mild weather, the whole machine gets *really* flaky.  I eventually found hitting the SS with the heat gun would make it behave.  No amount of fiddling with cables, ports, etc. made any difference.  But, we're having a warm spell at the moment, so I have to wait for it to cool off again to do any more testing.

I do seem to recall that the last plugin had changes to spindle accel which would require retuning, it didint seem to affect my servo spindle so I just presumed it was  VFD spindles it referred to. Then again as you have been talking to Greg I presume this is not the issue with yours as I would have thought it would have been the first thing Greg would have mentioned. 
So afraid I dont have an answer for you

Hood

Hood,

Interesting....  Greg never mentioned that, and I managed to miss it in the release notes.  I'll give that a try tomorrow if I have time.  The notes say it was running 8X too fast previously, which sounds like about what I'm seeing.

Ray are you meaning that with the new plugin it takes longer to spin up?

Hood

Hood,

Yes, exactly.  With the old ogb plug-in, the spindle spins up to 8K RPM in 2-3 seconds.  With the later plug-ins, making no other changes, it takes almost 20 seconds to reach 8K RPM, and does the same coming back down.  This is with a PWM spindle, and I've verified with an oscilloscope that it is the PWM that is ramping slowly.  Greg says I'm the only one having this problem.  Due to other problems I've been having (my SS gets flaky on cold days, and a quick shot with a heat gun gets it behaving) we suspected my board had a faulty FPGA.  But I now have three boards on-hand, and they all have the same swlo spindle ramping problem.  I'm *really* good at finding the bugs in other people's software and hardware.  It's a gift....

Regards,
Ray L.

I'm still working with Mach3 v3.042.02, and the v015ogb plug-in, both almost a year old.  With the current versions, my spindle takes 15-20 seconds to ramp up to speed.  This appeared, at first, to be a problem with my SS hardware, but I now have three different SS board, and they all behave the same.  I do still find the SS far preferable to the PP, but I do wish we could get these last few bugs out of it....

I was thinking that was too easy! How about 30 - OEM code?

Bill C.

DRO 30 is Encoder 2 position....
