Feedrate override chage increase/decrease%
« on: September 01, 2009, 06:06:51 PM »
First of all, sorry for my English language, so I am from the Netherlands.

I have a problem with the Feed Override function in Mach3 Mill.

When I in-/decrease the value, it changes with 10% off the feedrate.
Is it possible to change this in 1%. For the spindlespeed you can change this in the general config, but I can't find this for the Feedrate.

I hope you can help me.

With kindly regards from the Netherlands.

You could probably do it via VB in a button or even a brain.
Best option would be an analogue input and use a Pot to adjust , this would give infinite adjustment within the range. You would need hardware to get your analogue input though :( I use the Pokeys  for that and it works well.

I just put this in a VB button as a test and it works fine

FRO = GetOemDRO(821)
UNIT= 2
Call SetOemDRO(821,FRO-UNIT)

You could also set up a user DRO on screen so that you could set the unit without having to edit the VB Button
What you would do is put a user DRO on screen, that would allow you to type what you want the % reduction/increase to be. In the below example I made a UserDRO and had an oem code of  1111 for it, the VB in the button would be

FRO = GetOemDRO(821)
UNIT= GetUserDRO(1111)

Call SetOemDRO(821,FRO-UNIT)

Hi Hood,

That's  a quick answer.

I have tryed the code and it "WORKS". That's  the most simple way.

Very nice, I am happy with it.

Have a nice day
