[00:01:17] <andypugh> Good question
[00:01:56] <andypugh> Possibly retriggerability?
[00:02:18] <JT-Shop> For a similar function that can run in the base thread, and which offers higher resolution, see "edge".
[00:02:29] <JT-Shop> oneshot is floating point
[00:03:08] <andypugh> Conceptually a oneshot is used to stretch a pulse, and an edge detector to shrink one, but I think they do the same thing
[00:04:05] <atom1> which would be tighter code?
[00:04:14] <atom1> i don't need floating point really
[00:14:22] * JT-Shop is about to run out of leaks on the new hydraulic tank
[00:16:15] <andypugh> I am sure you can make some more
[00:20:59] <atom1> mmm i'm not seeing any change on the output of edge
[00:21:03] <atom1> or in halscope

[01:00:12] <andypugh> How infuriating. The last time I used the mill I was hobbing. I just made a box that is trapezoidal at the hob lead angle. (1 degree). It wouldn't matter but the lid is trapzoidal the other way.

[01:02:09] <atom1> basically just 2 and gates
[01:02:15] <atom1> and a pulse
[01:02:36] <atom1> andypugh, care to comment on it?
[01:02:41] <atom1> see any downfalls to it?
[01:04:04] -!- Nick001 has quit []
[01:04:41] <atom1> lemme repost it with the original code in the file for comparison
[01:05:05] <andypugh> It seems suspiciously simple :-)
[01:05:14] <atom1> it does doesn't it :)
[01:05:33] <atom1> you gotta get the pulse wide enough so program.pause program.resume see it
[01:06:06] <atom1> originally i didn't know if the signals were held or pulsed
[01:06:46] <atom1> the original was JT-Shop's i believe
[01:08:56] <atom1> now i will test that on 2.6 to see if it borks like the original code did
[01:09:10] <atom1> however i'm having problems compiling master right now

[03:34:04] <default_> hey, I just rebooted my cnc and its been a while since i've edited the .hal; if I want to reverse the direction on an axis, for instance change which direction is positive motion on my x axis, what would I edit?
[03:35:01] <default_> my machine has 4 joints tied to 3 axes, a simple xyz machine with one joint as a slave
[03:36:45] <default_> I read through the integrators manual and googled a bit and couldn't find what I was looking for
[03:42:03] <default_> I found the solution at
http://www.sherline.com/trouble.htm
[03:43:09] <default_> you go into the .ini file and change the sign of the SCALE value to its opposite, from positive to negative for example
[03:43:39] <atom1> change the sign of the scale

[21:56:06] <Jymmm> I turn on a piece of gear for the first time in days, and starts up fine. If I then turn it off, then turn it on 30 minutes later, it doens't start up properly, like it never got a proper power on reset. What does this sound like the issue could be?
