06:52 PM Hyoomin: Apologies if this is a bit of a noob question, and if there's a relevant chat channel I can be booted toward, please do say so, but...
06:52 PM Hyoomin: What is the relevant g-code for rotating a piece on a rotary table into a cutter? I haven't been able to figure it out so far, for whatever reason.
07:01 PM Tom_L: set the axis up as a rotary and use degrees: G01 A 270
07:02 PM Tom_L: your feed will also need adjustment for the rotary move
07:02 PM Tom_L: depending on the control it may be deg/min etc
07:08 PM Hyoomin: Ah; so it's just a G01 then, but with a rotary specific axis. Thanks for mentioning the matter of the feed rate. How would changing the feed rate play out if I'm rotating the rotary table while also moving X and Y? And is there a way to dynamically compensate for what the feed rate should be, given how far [X, Y] is from the center?
07:09 PM Tom_L: i will post a test program and show you the YT for it when i was tuning my rotary
07:10 PM Hyoomin: Also, am I sufficiently on-topic? ^_^;
07:11 PM Tom_L: better in #linuxcnc than the devel channel
07:11 PM Hyoomin: Ah.
07:11 PM Hyoomin: I will bear that in mind.
07:11 PM Hyoomin: These results didn't suggest that was an option, for whatever reason...

07:12 PM Tom_L: https://www.youtube.com/watch?v=pvDBfJQT2Ec
07:12 PM Tom_L: the code & video
07:13 PM Tom_L: the first cuts are very slow because i didn't have the feed adjusted for rotary there
07:13 PM Tom_L: i didn't bother retaking another video
07:14 PM Tom_L: but the code & result is there
07:15 PM Hyoomin: I see.
07:15 PM Tom_L: then if you want a helix program say X & A
07:16 PM Hyoomin: I'm concerned with a different plane of rotation, though. I'm more interested in the horizontal plane than the vertical.
07:16 PM Tom_L: so switch planes
07:16 PM Hyoomin: Yup.
07:16 PM Tom_L: G17..19
07:16 PM Tom_L: depending how the rotary is set up
07:17 PM Tom_L: that varies
07:17 PM Tom_L: but i would move further questions to #linuxcnc
07:17 PM Tom_L: not a big deal...
07:17 PM Hyoomin: Yeah, I'll take it there.
07:18 PM Tom_L: it's been pretty quiet in here lately
07:18 PM Tom_L: no harm
07:18 PM Hyoomin: Good to hear... about the harm, anyway. ^_^;
