Traverse problems

Newbie question. I just finished building a 3 axis CNC router. It cuts accurately for the most part, but when it does a fast traverse it will sometimes be significantly off. Not that it needs measuring to see, it pretty obvious.

I wonder if I am traversing too fast? What are typical causes for something like this?

The MAX_VELOCITY displayed in the GUI was set to 600 in/min, which is way too fast for my machine. I was using G0 to move around and my machine didn't like that. Changing the G0's to G1's slowed down the rapid traverse to 60 in/min, same as the cutting speed, and it worked very well.

Anyone know what the MAX_VELICITY is in? The setting under [DISPLAY] is set to 10.00, but shows as 600 in/min in the GUI. I can probably share my .ini file if that'll help.

It is in machine units (in your case inches) per second. 10 IPS X 60 = 600 IPM

Thanks Todd! That's awesome.

I wonder if that can be put in the docs? At least it's not where I was looking.

linuxcnc.org/docs/html/gcode/gcode.html#sec:G0

Until I found this:

wiki.linuxcnc.org/cgi-bin/wiki.pl?IniFile

Thanks again!
