General Mach Discussion / Re: Feedrate override in turn

« on: September 09, 2009, 06:01:41 PM »

I got the another slider on the screen following your instructions and the slider goes up and down OK but it doesn't change the S OV% or the little 100 at the top of the slider itself. 

To test it, I set the speed on the MDI line with M3 S2000.  It puts the 2000 in the Speed DRO but the slider doesn't change the percentage. Did I miss something?

Thank you again,
Bob

Hi again Hood,

Thank you for you kind and thorough answer.  I was able to get the FRO slider working beautiful by following your instructions.
I couldn't find the "None" Icon so I just skipped that step and was careful not to add any additional DRO's.
I tried to do the same with the Speed override slider but didn't see a "speed override" in the system function list.

If it were there, would we use the same format string SDTL5H250%3.0f  ?

Thank you again Hood.  Answers like yours benefit the whole community greatly.

Hello Hood,
I have the same problem.  I don't know how to get feed override to work in Mach3 Turn.  Is it possible to have the sliders for FRO and Speed override like in mill?

I don't know how to copy them from mill to turn.  Can you give me instructions as to how to do it?  I do have Screen4 on my computer and screen designer.

Thank you for your consideration.
Bob

To Poppabear.

In Practical lathe 2.0 when Homing All it homes the Z-Axis first and then the X-axis.  How do you get it to home the X-Axis first to get the tool away from the workpiece?

When I load the Mach 1024.lset, it homes the X-Axis first.  It's the same Ports and pins setup.   Thank you.

To Poppabear,

How do you turn on the Soft Limits in Practical Lathe vs 2.0?   

Also, What is the space shuttle accessory and what does it do?  Replace the MPG?

Your Lathe screen is indeed User Friendly and Practical.  Thank you.

Hi Graham,

Have you done any more work on the RaspScreen since Jan. 5, 2007?  I downloaded that one and it's the most useable one I've seen so far. 
I hope you'll complete it.

VB and the development of wizards / Re: Re: ATC VB script example for rotary changer...

I need a way to tell Mach3 what the "currenttool" is at startup.  In other words a way to ask the question "What is the current position of the turret"  and be able to type in the number from 1-8.  That will be the current tool at startup since, without BCD switches, there is no way to know where the turret is without asking. 

Also, how do these programs deal with tool 00 which Mach allows as a legitimate tool number?

Thank you,
Bob

Hi Drew,

Your program has helped me a lot to learn about script with mach3.  My turret has 8 positions, but no raise solenoid or index pins or BCD switches.
It is cycled one turret position by actuating a single air solenoid for about .55 seconds.

The turret is cycling fine by the following script in the file:    M20.m1s      located in the macros folder.

ActivateSignal(Output8)  'mapped to Port1 pin5, applies air to index cylinder
Code "G04 P.55"
While IsMoving()
Sleep 100
Wend
DeActivateSignal(Output8)   'turns off air to index solenoid which completes one index cycle.

So, any time I do M20 the turret advances and locks one position.  Great so far.


Now, I need to come up with the number of cycles or moves needed to get to the desired next tool.
In the M6Start.m1s, I'd like to calculate the unsigned value of the (CurrentTool minus SelectedTool)  which will give me the number of advances necessary to get to the next tool.  Then I can call or execute M20 that number of times to get to the selected tool.

How would you do that?  When you said M6 is not used in lathe but T0101, T0202,etc.  did you mean that M06 does not appear in the G-Code program itself, but just the T-numbers and that MACH3 knows to look at the M6Start when it sees a T-number?  (I noticed that you tested for M6)

Thank you for sharing your knowledge with newcomers to MACH.

For Drew,

Does your VB script for the HNC Turret changer require a PLC?  How did you connect to the turret encoder, and air cylinders, to read the BCD code?  Can it all be done through parallel port inputs and outputs?  I'm doing an HNC and would really like to try out MACH3 if I can get by the Turret programming problem.  The machine has a Fanuc  Control with Fanuc 00 motor/encoders on it now, which are coming off.
