Hood - this is all starting to make sense. I doubt you'll remember but ages ago I asked (on the yahoo board I think) why you needed the PP driver loaded even when you just wanted to EMULATE probing and THC. The answer was effectively that probing and THC have some of their "code" in the driver. At the time I couldn't figure out why - now it makes sense why. Really appreciate your time on this.

Can we start from scratch? When I look at the "Home All" button in lathe as it is out of the box, there is no VB in the button. Instead it uses OEM code 211. If you look up that in the OEM codes.xls file it says - Home X Home Z (turn). That seems to translate (after testing) to Home X THEN Home Z.

So - at some point I'm thinking you must have used a screen editor to change from using an OEM code to using VB - correct? (just trying to establish the full train of events)

Moving on. If I change from using an OEM code to using vbcode with:

doButton(24)
doButton(22)

Then it homes Z and then X

However, if I then change it to:

RefCombination(5)

It homes Z and X at the same time - i.e. what you want.

Two thoughts:

1) Can you try it using the parallel port driver and see what happens?
2) It's back to my thoughts that this may be an SS issue.

Meanwhile....

I have a question, since I only pretend to be a programmer.

Wouldn't RefX be a variable, and 1 be the constant? And since the RefX is not needed, then the integers are constants? Maybe that's what he means

What it says is:

‘ Define some constants
RefX = 1
RefY = 2

...etc...

So 1 indeed is a constant but that is not what's being defined - RefX is.

We can do literal constants and symbolic constants if you like

He he... I didn't point that out cos I thought people would think I was being picky - but it has no effect on the problem anyway - just two pointless (unused) variable decs and assignments. But whilst I'm being picky - the text in the guide is wrong anyway - they're not constants - they're variables.  There - got that off my chest - thanks Gerry

I don't think so - nowhere near fast enough nor synchronized. The thing is, in any feedback loop the outputs cause a change (movement), that changes things (arc voltage), the input comes in, you process it and the result is (hopefully) an output that brings things back to where you wanted. BUT even in a "perfect" system you're allways playing catchup. In Mach this would ideally translate to: every single step in the XY plane may result in a change to arc voltage so before we take another step or at the very least AS we take another step we step the Z. That obviously means that the input is processed for each and every single step i.e. at kernel speed AND in synch.

...but whatever, I'd still be interested to hear from anyone using a probe with the SS for their thoughts.

Can we use the Modbus?

For what?

I use this all the time in Mill but also just tried it on Lathe and it works fine here. Maybe another SS issue?

BTW - how did your other button problem turn out?

Don't split your "if expression then" constructs accross lines.

If
RPM > 2501
Then

If RPM > 2501 Then

« on: September 02, 2010, 05:33:45 AM »

wooow!

"if", "while", "select" and "case" in same sentence!! Looks like a script! =D

Nice one 

However, sorry but you CAN use strings in a select case - not very well explained in the Cypress UG but...
