feed rate
« on: September 11, 2010, 06:10:12 PM »
I think I got all where I need to be with one exception.

As I go through my machining and I use M6start mach chooses to jog feed rate of previous tool path goes to previous location and then jogs at full speed changes speed to current tool path and machines . Setting initial string say F200 does not affect that.

Is there way to change jogging speed that is not feedrate of previous tool path?

Not sure I am really understanding what you are meaning but if its an auto toolchange then it could be the VB in your M6 macro that is determining the feedrate.

Let me explain:

I do manual tool changes and use M6start to bring router to location where I do that. Also I have initial string with F200.

Say I have 2 tool paths in the program 1st at 30ipm second at 100 ipm.

What is happening, machine will come to change tool for first tool path to tool changing location designated as per M6start and after I hit start will proceed and jog to last position at 200 ipm then to 0.0 at 400ipm per motor tuning and to tool path start position and then proceed at 30ipm as per g-code. Now when that tool path is done machine will fast jog to M6start location for tool change after that is done and I hit start it will jog at 30ipm (previous tool path feedrate) to last position, fast jog to 0,0 and proceed with cutting at 100 ipm.   
Question: How do I eliminate or change jogging at 30ipm, say if that 1st tool path was at 10 ipm it would have jogged as per above situation at 10ipm. Is there script that overwrite this. Is there list of script numbers and what function they are resposible for?

What do your M6 macros have in them?

I am not sure what is in the standard M6 macros as I have custom ones so if there is no feedrate specified you could add it or even a G0 if you wished. I would imagine because the new feedrate is being called after the M6 it will not take effect until after the macro has completed.

ok m6start brings machine to tool changing location, m5end moves it back just in case it was jogged of position i know that.

What macro would be responsible for this condition or some typo of setting.

How are you doing the movement? G0? G1? or manual jogging with the keyboard?

Sounds like it's using both G0 and G1? If your using "code G0 ...." or "code G1 ....", then add a feedrate in the move.
You might also need to use SetOEMDRO command to set the current feedrate.

Really need to see the code to know for sure.
