1. Can you not force SetMachZero() to set the DRO to zero at its current position? I'm not understanding why this needs to be calculated I just want to push 0 to the DRO.
4. One job I'm running is 0.25" in size with features as small as 0.005" the next job is 12" in size with very few small features. I find CV dist tolerance to be a nice feature but an appropriate distance is different if you part is large or small.
5. I was referring to mach's toolpath display not mach itself. I find myself turing the toolpath on and off. On so I can look and off so I can run cause mach runs better with toolpath off on large gcodes. I'm guessing without a major rewrite of the viewport there's not much that can be done.
)6. Copy and pasting stupidity. Sorry. Not yet I'll try this on Friday when I'm back at the shop and post my result.I understand!
7. Given 100mm/min is program feed, it is a single axis move, actual feed is 96mm/min, and there is plenty of distance to accelerate to that velocity and the max velocity of the machine is >100 100- 4 = 96/100 = 96% = 4% off in speed.No fair... you can't change the numbers on me... that is not what you posted! The problem is that we are reporting what it IS doing.. this is something that we will look into more in the next large rev.. for now it is what it is ..
. I've also had a problem with the feed rate but in my case I've adjusted it with the FRO +/- buttons. Then somewhere along the way the machine changes speed apparently on it'd own (Perhaps commanded by an F word but not to the extent it changes) and the FRO buttons don't do anything any more. You can adjust them from 0 to the max and press the FRO reset and the speed does not change. You're pretty much stuck with the speed you have unless you start the G-code program again.

Downloaded and ran 3.042.004 version and had nothing but problems. Code that ran perfectly in version 3.041 would not run without problems in arcs, etc. One thing I noticed on the Diagnostics screen is the abs max x, y, z were all out of proportion to the drawing in the code in mill mode. The figure in the code is 11.5 by 5.5 inches - the Diagnostics screen showed the max to be like 116 (somethings). Yes, I copied my old xml file into Mach before running the code. Yes, my native limits were in inches. I had the same problem with another code.

1. Machine Coord DRO's don't always zero they will have 0.0013 left in them sometimes.I think you are setting zero with the Reff command with no home switches .. This is a known problem at this time (I will fix it but it is working with home switches). Also if you are going to set zero you should use the Zero x,y,z buttons... Last what is your steps per unit ?? You may not be able to get to zero (Limitation of your machine) and this is as close as the software can make your machine round the digital steps to zero.
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.Could you please give an example of what is not correct? For example are you running loops with offset shifts and so on in the code? If so it is hard to tell if you are in the correct position when the reference position is changing
That is the only time that I know when this is not correct..4. Mach seems to be having issues saving CV state if you change the CV dist tolerence or turn CV dist on/off.You should close and reopen the software to back up your settings...This is a very good idea
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.It is also the calcs for drawing the toolpath that is slowing down the load time... In the diagnostics page please turn off the toolpath and tell me if you like that better.
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 cyclePlease have a look at the M6Start.m1s and M6End.m1s macros and change them to your liking
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".
This is the only way to change how the toolchanges are done7. Machine is always underfeeding. If I set feed rate to 100mm/min and give the machine plenty of room to make a single axis move and get up to speed\
it is always under feeding by about 4mm/min, it never reaches the programmed feedrate and my max velocity is 800mm/min. It didn't do this in older mach versions.
I think you may get it LOL..
