A warning would be nice. A warning with option to continue with spindle slowed would be a bonus. -Tom > On Feb 7, 2018, at 4:43 PM, andy pugh wrote: > > On 7 February 2018 at 20:02, John Kasunich wrote: > >> >> LinuxCNC will NOT reduce the spindle speed based on the limits of your Z >> axi

Re: [Emc-users] CSS and spindle-at-speed during a G33

My experience corroborates Peter and John’s descriptions. I tried cutting an SFM that was above the capability of the Z-axis to move, just for fun. Rather than a thread, I essentially got a bored out cylinder with some thread-like lines as a finish. So it doesn’t slow the spindle to the axi

Thanks Chris…for both the information and one of the most apropos example of autocorrect I have ever seen. "The spinach is turning in x-direction the carnage in z” I think this will be my new signature line ;-) -Tom > On Feb 7, 2018, at 2:35 PM, Chris Albertson wrote: > > The G33 says to do

Re: [Emc-users] CSS and spindle-at-speed during a G33

The G33 says to do a synchronized move. This is physically impossible. The Z axis has some limit on it's ability to go from zero speed to the commanded speed. So the controller is reducing the spindle speed so as to match the ability of the z-axis motor. ALL multi-axis moves are this way. Yo

As I replied to Andy, spindle-at-speed is just coming from vfd-at-speed in custom.hal. net gs2-at-speed motion.spindle-at-speed <= spindle-vfd.at -speed I am not using wcomp or near component as suggested in the manual: http://linuxcnc.org/docs/html/examples/spindle.html

Re: [Emc-users] CSS and spindle-at-speed during a G33

That is a good question, and one we have recently asked ourselves. In fact we changed our threading routine to fix the RPM because at least then the spindle is not constantly accelerating and decelerating. But, to be honest, CSS should work fine, all it does it change the spindle speed for a g
