WES the Minimum move distance is .010"  .

Wes I don' think this is a problem I had to think back a long time ago Art had said there is a MINIMUM move distance for the G31 to be accurate. I recall the number being about .050" before a trip.

(;-) Mach4 HAS the same problem with micro G31 moves I just tested it as well. 

I will dig into the old test notes to see if I can find the conversation with Art.

As far AS I remember said there is to be ZERO mach3 fixes. But if the bug holds up that makes the G31 just about useless.

I will do more testing JUST to make sure. But it sure LOOKS like a big old bug from here.

Just to be sure it needs to be tested from a tripped point perspective NOT just an end of travel issue. IT MAY NOT even effect the trip point values as they have always been dead on accurate.  BUT you won't know until it is tested from THAT perspective as well. THAT would be the really important test. IF that is munched oh well.

OK I took it out of the wizard to a MAch3 page , still there

I took it back to V.022 , Still there

I even changed out the INC dro with a user dro just to make sure(;-) , Still there

I even added extra wait state time for DRO updates  JUST to make sure, Still there

G01 moves are perfect
G31 moves are munched

I even reversed the G01/G31 in the order of execution in the script and the problem followed the G31.

That will explain the problem people have had with the TLO routines not repeating.

YEPPER there is something really ODD going on with the G31 moves from a wizard.  Next is to test it outside of a wizard.

Then back up in ver to see IF it goes away. It is in V.067 and V.062

I tried your wiz but it did not make any sense without intructions.  ALSO it takes FOREVER to run a segment. I will retry it now that I know a little more about it.

Mach3 under Vista / Re: Minimum PC requirements vs real life (Newbie)

Just a note. ANY function outside of MACH3 CAN(but not always) interfere with Mach3 being able to maintain sync with the pulse ouput. It all depends on how loaded the CPU is when the outside event occurs. ANY program that is running either in the foreground OR background can cause this problem. Eventually even a low cpu load can be effected. It all just DEPENDS.

That is why it is recommend to ONLY run MAch3 and NO background or monitoring programs when controlling a machine.

Just a thought, (;-) TP

OK I will review that .

Are you sure you are not seeing error from the probe trip itself. Lower end 3point pivot probes CAN be innaccurate when moving in certain directions such as not in line with a pivot ball. They are 3 point most accurate and 3 points worse accurate. It between it can vary as well.

Also are you sure it is not a step resolution problem where it cannot get to the position because of step resolution. It will add the remainder of the lost step value into the next move.

Just a thought, (;-) TP

Also what you need to understand is for the Feedhold solution to work you HAVE to leave your machine and computer on all the time you cannot shut it down or you loose position when you restart.

Even if you do a run from here on a startup you cannot just RFH without referencing the machine first. Either manually OR by refhome. Until Reference the machine MAch3 really does not know where it is at in 3d space. It will just ASSUME it is somewhere and set that as the position.

OK THE MMD is NOT the post file the post files are still PST. The MMD is the definition file for your machine.
