Bugs in Mach 3.42.015
« on: October 31, 2008, 11:42:39 AM »
1. DRO's don't always zero they will have 0.0013 left in them sometimes.

2. Step and Dir pulse lengths on some installs will reduce upon opening and closing the motor tuning window.

       ie.  Step=2  Dir=1    after opening, setting, closing , opening motor tuning will change each by -1   

3. Program extrema is not being calculated correctly.

1) could be due to your resolution. What's your steps/unit?

I'm in millimeters. I have 800 steps/mm. This is the resolution of my lead screw/motor combination. I use 0.9° steppers with 10microsteps with a 5tpi ballscrew.
My parts come out to the correct size and I can step the machine in about 2micron increments so all works.

What does  that have to do with me clicking the "zero" button  and the DRO not going to zero?

No comments on bugs # 2 and 3?

Velocity of machine is not ever reaching targeted feedrate.

IE. Program a single axis movement like
%
G01 X0 F100
X20
M30
%

Mach never actually reaches the programed feed its always about 4mm/min velocity slower than it should be.
This does not happen in 3.41

swarfboy,
bug#2 existed before, but can't remember which version or when,but it was fixed, since that was happening to me and a few others.Was a PITA. Are you using a SS?
Maybe a quick search will bring help bring back memories since it was 6 months or so ago.

Don't understsand #3.

Rich,

 "Are you using a SS? "  Whats SS?


I'm using the latest release as the subject title says and I have this issue still on one of my machines. I've cleared out and reinstalled Mach from scratch still a problem.

 #3 There are program extrema DRO's. Mach parses the Gcode and finds the max and min values of the Gcode for each axis. This tells you the size of the work area for a particular code.

Wow. 165 views and only two people have something to say?

 Were you asking a question or as I was thinking reporting bugs?

Brian,

If I were you, I would post these over at the Yahoo Mach groups as that's where Brian and Art seem to hang more than here.

You'll probably get more input over there on these specific items since they're constantly going over the new revisions.

Brian,
Not surprised, assume a lot of people haven't tried the latest version yet, like me, as i am using 3.042.12.
SS is Super Stepper which provides for using the USB port, forget about it.
I couldn't find anything about Mach not saving the step & direction value other than around Ver 2.61.
Sorry, but for such a PITA, you think i would have remembered what fixed it or what i did.
That said, maybe someone else may post about it.

Reporting bugs. Thanks Dave I'll head over there. This is the tally so far.

1. MAchine Coord DRO's don't always zero they will have 0.0013 left in them sometimes.

2. Step and Dir pulse lengths on some installs will reduce upon opening and closing the motor tuning window.

       ie.  Step=2  Dir=1    after opening, setting, closing , opening motor tuning will change each by -1   

3. Program extrema is not being calculated correctly.

4. Mach seems to be having issues saving CV state if you change the CV dist tolerence or turn CV dist on/off.
   Closing and opening the session fixes it, but I've learned mid session changes are risky behavior.

5.Mach is parses the code pretty slow when you open a file. I'm guessing it parses the code for gcode errors and finds program extrema.
I would like to be able to turn off the program extrema calculation method or see it rewritten using RegEX so that it parses faster.

6. If you jog the machine during tool change M6 (so as to be able to physically get to you spindle and change the tool upon pressing cycle
start mach moves to its previous position with no warning or way to cancel this. This needs to have the same dialog added that you get when using
"run from here".
