Rapid rate

Post by polemidis » Thu May 24, 2018 8:18 am

Most likely its in front of my eyes but I cannot see it!

Where can I set the rapid feed rate? The tool moves at the same speed on G0 and on G1/G2/G3 moves!

Rapid speed is controlled/limited by your machine, not SC. Make sure you are not in dry run or have your rapid override turned down for starters.

Thats the export of the grbl post processor. There is no Fxxx on the G00 moves. Correct me if I am wrong, but I have the impression that at the above example the G00 will move at the speed of the last Fxxx value that was given, either it was G01 (or G02 etc) right?

I am not familiar with grbl.
Normally there is no feed rate associated with a rapid move, which is controlled by the machine/control.
Maybe someone familiar with grbl could help.

G0 tells the machine to move as fast as possible. You don't define a rapid feed rate in the code. in The case of grbl the rapid feed rate is defined by the configured maximum rates. This page may help http://www.diymachining.com/grbl-feed-rate/
