Gentlemen, I remember NC/CNC controls that use/used the X in ways other than just an axis designation. I was uncomfortable with that on the first such control I used. The previous G code determined the treatment of the X in each position on the line.
I seem to remember drill cycles as follows G81 X Y Z F X X X X with the manual telling the programmer what each X position on the line was used for. Immediately prior to this type of code many controls used a tab sequential format where the position on the lline was the only way of determining what a particular value was used for. I believe in the tab sequential format the XYZ labels were only used to allow the operator to easily read the code. I am sure the old computer programmers remember the tabs and fields that were required when writing code. Maybe some of the younger ones also. My daughter was griping about an OLD!!! man she works with. I asked her how old he is. He is 2 years younger than me! Of course I thanked her for the compliment. :) thanks Stuart On Wed, May 23, 2012 at 6:36 AM, John Thornton <bjt...@gmail.com> wrote: > You might reference the g code manual for LinuxCNC rather than guess or > assume LinuxCNC G code is the same as some other control. > > John > > On 5/23/2012 12:35 AM, Claude Zervas wrote: > > Hello, > > > > Just wondering if someone might know why LinuxCNC interprets the G04 > > dwell command parameter as seconds instead of milliseconds? > > I'm fairly certain most other machines (ie Fanuc and others) interpret > > the P value as milliseconds. > > For example, the command: > > > > G04 P3000 > > > > is interpreted by most machines as stop the tool for 3000 milliseconds > > (3 seconds).
