Hi guys,
i have a problem with my version of r2.63.
I use the same licence of an older version of mach3 and it seems it has some problem while moving in working coordinates.
The machine is doing the g0 perfectly but doing the g1 or g2 it moves wrong even if the computer says it move correctly.
Now the question is: there are different licences for different versions of mach3 or the same licence work for all the versions.
Thanks for anyone that answers.
bye

Same licence so thats not your problem. Can you give more details of what is going wrong?

Hi,
thank for your answer.
The problem is that the movements that the machine does is not the one that the computer displays and say to do.

what do you mean? Travels wrong direction? Travels wrong feedrate? or what?

Saumur, i have the same problem, did you solve it?, please answer

FMUR and Samur,
Please give an example.
1. What did you command it to do ?
2. What did you expect it to do ?
3. What did it actually do ?

Thanks Overloaded, the point is ,the calibration servo, encoder, screw was setting in mm, that was checked with comparator and command jog and was ok. I thought everything ok for production but running a piece observe that both the x and z gain 0,06 per mm.

may affect the width of pulse or debouncing time???

Mr OVERLOADED may affect pulse width or debouncing time.

FMUR, Saumur, sonds more to me you have either overwritten your XML while updateing or you're not opening the right profile.

Sorry Mr. I made a mistake, but the problem is as you can read

Not exactly sure what you are asking.
Make sure that your "Steps Per Unit" is set correctly for each axis in "Motor Tuning".
And you must consider your backlash....if you have any.

I can't explain you what is going on since i have no idea.
All i can say is that when i do some moving testes in g0 the machine moves correct, when i load a program the machine makes the profile wrong.
100% sure the program is OK, i just wanted to know if it is a licence problem but you said it's not.
So anyone got a clue on what this problem is?
Thanks

If you cant tell us whats actually happening then its almost impossibl;e to sugest a resolution to your problem. I understand it can be difficult to explain whats happening but a few clues would maybe help us out.
In the mean time could you attach the xml for the profile you are using and also your code that you are trying to run.

My situation is exactly as Saumur,I am going to try to explain, i have two machines working x and z ,the program is the same ithe profile is perfect in one, but in the other is wrong.the second machine was set up last week , I made the normal calibration screw, backlash, and motor tuning, with the dial indicator (10mm stroke) move 1mm with jog and indicator was exactly, move 2mm was the same and so, but if put to travel 5mm program g1 x5 each 1mm on the screenshow 1,06mm on the dial indicator, at 2mm on the screen the dial goes 2,12mm and so, thats is the same in axe z, I hope anyone can help us

Please attach your xml and give details of the hardware you are using, also the revision of Mach you are using.
If Steppers then are you using micro stepping?
If Servos then what are the encoder counts?
What pitch ballscrews?
What gearing if any?
