Could some one recommend a ploter that marks the respective line number
on the plot? I have some G-code and I want to adjust the feed rate at
acute angles. It is hard for me to look at the G-code to figure out where
the angles are.

BTW, is there free or low cost software I can use to do the feed rate
adjustment according to some parameters I set?

Thank you very much.

Try, www.NCPlot.com

Check out the latest Beta version.

What you do is load your g-code file into NcPlot, after it plots the code, click on the part of the plotted line that you want to change the feedrate, then Ncplot will highlight that exact line of code in the textbox. Then just change your feedrate etc...
