Well, TBT Phil, if the lathe does a miss-queue, I might miss it. That test was while running a modified copy of lathe-pawn to cut 50 copies of it in air. Using css so I was quite consious of the sound it was making. And that was done with stock, noisy as all getout, steppers driving it. Now, with servo-steppers moving it like casper the ghost, I might not hear a stutter. Generally, the only sound that lathe makes now is the whir of the spindle. And it can now move 2x faster for rapids than it could with the hammering steppers. The difference in this case is probably that you are using your network to drive the machine, I am not, I'm using a 7i90HD interface in spi mode, boosted by 3 7i42TA's, driven by rpspi.ko, transmission to the 7i90 is at about 42 megabaud, and card responses to the pi are at 25 megabaud. So my wifi is disabled on purpose to keep my neighbors cell phone from using me as a hot spot, and my wired network is free for other normal uses. Sometimes, Phil, there actually is a method to my madness. :o) > Phil T. > The Feral Engineer > > Check out my LinuxCNC tutorials, machine builds and other antics at > www.youtube.com/c/theferalengineer > > On Wed, Jun 2, 2021, 2:16 AM Gene Heskett <[email protected]> wrote: > > On Wednesday 02 June 2021 01:32:24 Chris Morley wrote: > > > I've considerable experience in screen building and a bit using > > > remap.
