I have been thinking about this and I can do this in the Macro Pump... So here is a quick little bit of code to fix the max FRO problem...

'This is to set the MAX FRO to 125%
If(GetDRO(21) >125) Then
   Call SetDRO(21,125)
End If 

This should fix the problem

Brian,

Thank you for thinking about this and offering a solution!

2 things... idon't know what a macro pump is.  I'm going to crack open the manual and see if I can learn about it.

The second item is, I think this programming tweak does resolve my request to place a limit on the max FRO but, if I understand how you propose to do it, I forsee it as being done in a restrictive way.

A 125% max FRO might work for a certain program cutting a specific material but what happens if the material changes and you want more (or less) FRO limit?

Try this and see how you like it... after that we will see if there is more that we can do.

Go under Config/State and check Run Macro Pump  take the Macro pump file that I sent to you and put in the Mach3/Macro/Mach3mill. once you have done that close the program and restart Mach3. you should be good to go after that....

   It didn't work.  I followed your instructions.  Do I need to call out the macro in my Gcode?

Thanks,
Sid

Where did you place the macropump.m1s file? Did you turn it on under Config/State? If that checks out okay Post your XML and I will see if there is a setting that you need to have set.

Thanks
Brian

OK, I figured it out and got it to work.  Here's what happened...

When I clicked on the link for the macro you posted, the "SAve As" dialog popped up and the default file type was set to .txt

So, when I copied that file into the Mill Macros folder it had a .txt extension and therefore was not being recognized as a macro file.  Now it works good. THANK YOU!

So, next question.  Is there a way to make the 125 value in your macro a variable field value?  Could we then create an input box on the settings screen in which this variable value could be plugged in- kinda like the way you can type in a Safe Z value?

Obviously my comprehension of the programming capabilities in this area are limited so please forgive me if this is a Lame question.

Thanks again Brian.

Regards,
Sid

Sid this is a simple change but I am going to have to make a new screen set where you have a place to set the value... I will post a new set and Macro pump in the next few days.

Brian,

You are the Man! 

I have played around with Screen4 and can do some basic modifying and would like to be able to learn more about what you are going to do.  Is there something I can do to help? 

Thanks!

Sid

You need to add an LED with an OEM code for the DRO. The OEM code should be 1000 to 1250, I will put the value in the Macropump. See if you can add it to the screen set.

Yo Brian!

OK, I think I added the LED.  It's next to the Feed % DRO.  Do I need to create a DRO to input the max number for the F???

I used OEM code 1000.  Check it out and let me know what's next

Thanks,
Sid
