General Mach Discussion / Re: Losing Position

Hi Mike,
My position problem is not just a few thou.  What happens is one (or more) of the axis will drop a large amount of positions, sometimes to the point of crashing the entire machine.  It is rare, but still a pain.  I have not had a program run over 6 hours yet, so can't comment on the precision after that period of time.  I do not think it has anything to do with MACH's interpretation functions.  It could be something in the computer system such as non-ECC memory or something weird like that.  Anyway I haven't had a problem since turning off "Automatic Updates" and never allowing the monitor to go to sleep or screensave. 
BTW - When setting the priority of Mach to Realtime, I have lost a USB wireless mouse function.  I was only manually moving the gantry, but had to reboot as not even the 3 finger salute would break into the system.  So beware.  I am going to try some higher priorities just below Realtime.
Regards
JWI

Hi Brett,
I have optimized the unit per the guide, but only succeeded in stopping all communication from the PC to the control box.  The PC is dedicated and the control box holds 3 Gecko 320's, an opto BOB and a very good Power supply with a flow thru cooling system.  The problems in the past have been in very long runs < 3 hrs. where one or all of the axis' will loose touch with reality.  I haven't had a long run come up lately, but when I do I will try the Realtime function to see it it cuts off the extra stuff that the MS OS produces.  I'm interested in this as the EMC program seems to thrive in a realtime environment
Thanks for your reply.

I have had some lost positions on some long runs cutting foam and soft woods and haven't found the culprit except maybe the OS from Microsoft.
Has anyone tried the REALTIME function available in Task Manager??  I stumbled across the function by right clicking on Mach3 in the Process Manager and a drop down appears where you can set the priority to Realtime.  You also get a message indicating some bad things can happen.  BUT, if this stops MS from interrupting Mach3 's functions during a prolonged run .........
