12:49 AM lcnc-relay: <meisterdippel@> moin
01:20 AM lcnc-relay: <ntulinux2467@> so linuxcnc got removed from debian? or just testing?
01:39 AM roycroft: i heard that one point it got removed, the reason for doing so i forget, but it is part of the current debian distro
01:39 AM roycroft: $ cat /etc/debian_version
01:39 AM roycroft: 12.9
01:40 AM roycroft: $ apt-cache search linuxcnc-uspace
01:40 AM roycroft: linuxcnc-uspace - motion controller for CNC machines and robots
01:40 AM roycroft: linuxcnc-uspace-dev - PC based motion controller for real-time Linux
01:40 AM roycroft: there are no third-party repositories in /etc/apt/sources.list.d on that machine
03:52 AM lcnc-relay: <lackdaz@> @irc_liberachat__unreal_:jauriarts.org: @_unreal is ESTLCAM meant for windows?
06:14 AM -!- #linuxcnc mode set to +v by ChanServ
06:14 AM Tom_L: morning
07:11 AM lcnc-relay: <travis_farmer@> Morning
09:14 AM lcnc-relay: <skunkworks8841@> up to a pound of silver contacts

05:41 PM JT-Chicken is now known as JT-Cave
06:37 PM lcnc-relay: <zincboy_ca_on@> What you are talking about is almost always done in CAM. You can use tool offsets but the lead in/out is more tricky as you need to have a greater distance move than the compensation radius. I usually use wear offsets so the tool diameter is compensated in CAM but you can adjust by +/- the lead in radius.
07:04 PM Unterhaus_ is now known as Unterhausen
07:04 PM Unterhausen: I need to find the cut in the invisible fence wire, and someone offered to find it using dowsing rods
07:05 PM xxcoder: in networking theres something called fox and hound
07:06 PM xxcoder: isnt there version of it for regular wires?
07:06 PM Unterhausen: I feel like I know where it is more accurately than can be done with dowsing rods
07:06 PM Unterhausen: there are all kinds of methods, I was hoping not to spend any money
07:07 PM Unterhausen: maybe I should break out the signal generator, pretty sure it will hit am radio frequencies
07:38 PM lcnc-relay: <skunkworks8841@> Pulse generator and a oscilloscope.. (and the speed of light)
08:05 PM Unterhausen: I have a pulse generator too
08:06 PM Unterhausen: Problem is sensing the signal.
08:07 PM xxcoder: would current detector detect pluses?
08:07 PM xxcoder: its essentally how fox and hound works. fox is plusing wire, and hound detects if the specific spot is getting pluses
08:44 PM lcnc-relay: <skunkworks8841@> I think you would get a reflection at the break... Then you calculate the time between the pulse and the reflection.. then calculate the distance by using the speed of light. (Divide it by 2 because it is there and back)
08:45 PM lcnc-relay: <skunkworks8841@> At least I remember doing something like that in college
08:46 PM rdtsc: or try this "fox and hound" https://www.homedepot.com/p/TRIPLETT-Fox-and-Hound-Premium-Tone-and-Probe-Kit-3399/315142119 connect signal generator to wire, use probe to find wire undergound (will hear tone) move until tone disappears = location of break
08:48 PM rdtsc: can find much cheaper
08:53 PM jdh: I got a cheap $20ish one to try to track down a wire. Made it a few feet outside and could never find it after that.
10:41 PM roycroft: we used to do that to find bridge taps in the "clean" lines the telco leased us that did not work
10:42 PM roycroft: we'd send a pulse, time the echo, calculate the distance, and then tell the telco where to find their bridge tap
