General Mach Discussion / shuttle mode, step/velocity and single step

« on: June 27, 2009, 03:15:11 PM »

Forum members,

Finally installed and tested one MPG. Works super! Tommorrow I will place the second one.
Some questions in the shuttle window:
1  In single step mode, if I turn the mpg, not every click is one step, although the pause between the clicks is long enough.
   This is strange because in multi step mode every click is absolutely one step.
2  The step/velocity mode has a DRO next to it. I can not find any difference in changing its values, so what do they do? And also, if the turning speed of the MPG is slow enough, and you enter the stepmode from the step/velocity mode, the steps are all different in size.

I'm still cutting air, but cannot wait trying it for real,, must be much more fun compared with the old cnc program, which had none of these possibility's.

Thanks Hood,

Never worked with brains, nor with VB.
There is a long way to go but,,,, I like it.

Could you advise a trackball?

Hood,
The Pokeys is a good idea. Have read about it on the forum.
Instead of a rotary switch I have got a few optical encoders with 25 clicks per revolution. Perhaps they can be used for these applications.

Your keyboard on the picture is real nice. Is metal?

Rich,

Thanks for your answer.
All the help on this forum is great.

Changing the values is also explained in the manual of mach3 (which i read over and over again)

But I was wondering if there is a possibility to connect these values to a "trim-pot", and then pick a value by turning the trim-pot.
The answers from Hood already explained that it is not possible to go higher or lower,,, you just  cycle through all the values. It is not possible to go one step higher, and then one step lower again. You have to go all the way up or down.
Or is there another way of doing so??

Hood,

That is precisely the information I'm interested in.

As soon as there is time, I'm going to try out (still have to work for my living)

thanks

BluePinnacle,

Thanks for your reply.
I was just experimenting with the method you suggest (it is also suggested in the manual of mach3).
But then I found that my ballscrews have 0,05 mm backlash.
Nasty, perhaps I have to buy new ones.

Looks very professional to me Hood.

Your explanation about the VB script and the direct input in the DRO's shows that there are lots of possibility's in mach, and also that there is a long way to go for me.
Have been reading a lot, and I have seen a lot on you tube, but the process of building these extras on my own lathe is very time consuming.
But your help is great!

Hood,

Thanks again,
It is clear now.
It is not a fault om my computer.

Is it possible to get more then 10 steps (increments) in this jog cycle?
And what sort of screenset do you use with your lathe? I'm curious.

Hood,

Just the plus and minus button on the manual screen, under "jog cycle".
Hit the plus and the value gets lower instead of higher.

Oke Hood,

Thanks, I'm going to try.
The closer one get to finish the work on the lathe, the more questions appear.

Here is another one:
The plus or minus from the jog cycle buttons are not working as a + or a -, the number goes from high to low, no matter if you hit the + or -,, strange.
