General Mach Discussion / Index and/or timing on >config>ports and pins>input tab

« on: January 09, 2010, 04:44:48 PM »

Can't get proper true spindle reading,,, the DRO shows chaotic numbers

Situation:
Optical sensor (reflection type), two slots, wide enough

On input signals: Should I use index and timing?
Do they use the same pin?

On outputsignals: should i use Enable 1, or Output 1???


I think this causes other problems like not being able to set the control ratio from the pulleys (the seem to live a life of there own).
Have been messing around for days and days now,,, I'm missing the basic vision behind this.
And without a good true spindle reading its not possible to do threading.

On all the other functions Mach is really fantastic and works great.

Thanks for your reply Rich.

You are right about the money. I think that programs like mach and lazy cam or turn, should be payed for, as a sign of respect to all the people who worked on it.

I do not understand your remarks 1 and 2,,, tool application- you mean which tool you use for a specific part you are turning?
And the basic prepratory lathe setup?
I know there is still a lot to learn for me.

I will read your manual, perhaps it gives me some understanding of the subject

Rich,
Thanks for your answer.
I am going to play with the MPG configuration you mentioned. It seems a good idea.
My MPG's do 25 clicks or counts per revolution.

Have read everything about lazyturn. As soon as I am more self-confident with my lathe, I will use this program (and buy it). But for this moment, using the MPG's and connecting the wizards together is more than enough.

Another subject:
When I bought this lathe (with an old Atari computer and a totally different, very simple cnc program) all my friend advised my not to buy it. "You will never need to do tapers, arcs or fillets" they said, "and you will never be able to do some proper turning on such a device,,,much,, much to complicated". Now they ask me to do some work they can't do on their own machines (like a tooladapter with tapered backend).

Interesting Rich,
Calibrated for movement,,, in what mode have you putted them?
1 velocity only
2 step/ velocity
3 single step
4 multi step
I think it must be velocity only,,, but then the smallest step you make is not so small at all
Step/velocity is confusing for me, no matter what value of the DRO next to it is, it does not make any difference (perhaps I make mistakes).

And the other lathe work you make, is it mostly done with a program???

Thanks Hood,
So I suppose you always use a wizard or a program to do your turning?

If I set the speed when I use the MPG's, there is always the danger of making to many steps.
I turn the MPG one click to much, and the tool doesn't stop on right place,,,, argh.

Hood,
Did a lot of lathe work to get some experience, to get used to the machine and to make some things i never could make before I had a lathe.
Did a lot with the MPG's to be able to control things by  hand.
Here is the question:
If you work with the arrow keys on your keyboard, you can use "continuous jog, and with the "slow jog %" you can determine how fast your tool moves.
Is something like this also possible when your working with the MPG's??

without misspelling (i hope)

Hood,
1    suppose you want to make this item


I would give the jogcycle DRO a value which would correspond with the stairs on the z-axis, turn the z-axis MPG one click, tool does its move, hit the "go to Zs" button (OEM code 1017,, return to x= 0 and y = 0) and then change the value of the jogcycle to 1 mm, turn the x-axis MPG one click, change the jogcycle value to the previous value, turn the z-axis MPG again, hit the "go to Zs" button and so on.
But reading your answer,,, I suppose there is a faster way of doing this.
I know, one could use the wizards, but I'm curious how you would do a job like this
The problem with the way I described above, is that when you forget to change the jogcycle value, before turning the Axis, you would pound your tool into the stock!

2   I'm going to try the shuttle mode,,, thanks for your explanation
