Setting different feedrates for each axis.
« on: April 20, 2009, 07:04:33 PM »
Hello people.

I've been bitten by the hobby CNC bug, so i have my own machine now up and running. G-code(rs274) is really nice, as it is similar to what we use at my place of work, Sieb&Meyer sintax.

I have a small problem though:  would it be possible to specify the feedrate for each axis at the begining of a program?  When drilling thin boards i would like more speed on the Z-axis. I'm thinking something like this: FX 1500 FY1500 FZ 2500. Can it be done without specifying the the higher feedrate on every line that the Z drops or retracts?

Thank you.

You could lower the speeds of the X and Y in motor tuning to the max you want them to go.
