Title: not responding to f feed codes?
Post by: vz58 on August 25, 2012, 02:08:39 PM

My computer crashed so I bought a new one.  everything works great but for some reason it does not respond to f codes.  I have to set the speed by using override on the main screen.  I has to be something simple but I cant figure it out.

i.e.  if the program says f20 it runs wide open.  if the code is f3 it runs wide open.  I can only control the overall speed on the main screen override.




Thanks

Does your code use G0's, or G1's?

G00 are rapid moves, and are not affected by F words.
You need to program using G1 for the F words to control the speed.

G0 (G00) is a move at rapid speed the F word will not have any effect on it, you need a G1 (G01) if you want a linear feed at the specified feedrate.

Edit, Too slow ;D
