Title: Waterjet/lookahead/accelerate-slowdown
Post by: cheeky on February 05, 2007, 03:28:35 PM

How and where do I apply settings to make the feedrate slow down before a curve and speed back up after it? Can I adjust these settings?

Hi,

In mach click on the settings tab. Look for "CV Fedrate" this is the speed mach will use if the angular limit is reached. You can set at what angle the alternate speed kicks in...

If by curve you mean G2/G3, then just change the feedrate on those lines of code.

Thanks Ger21 and Chad. I cant do gcode so I dont know what youre talking about.(Spolit by Sheetcam)
Chad? where is the "second" speed you are referring to.
I worked on waterjet machines and I could specify the rate it slows down and speeds up in mm/min or whatever.
tnx again

Sorry i didn't explain that very well.

The "CV feedrate" is the speed it will slow down to.

The "angular limit" is what angle and above is used to set the slower feedrate.
