[00:03:52] <SWPadnos> andypugh, I don't think a translator component could work. If you want to write to the pin, it has to have that ability
[00:03:56] -!-
theorbtwo has quit [Ping timeout: 240 seconds]
[00:04:19] <andypugh> You can write to an IO pin, but only from another IO pin.
[00:04:31] <andypugh> (can't you?)
[00:05:26] <SWPadnos> I don't remember the exact rules, but I think it's something like as many readers as you want, at most one writer, and (here's where it's fuzzy) only one or two IO
[00:05:50] -!-
Loetmichel has quit [Ping timeout: 252 seconds]
[00:05:58] <andypugh> I think IO pins are in pairs.
[00:06:08] <SWPadnos> something like that
[00:06:11] <andypugh> AFAIK you can only net an IO to another IO.
[00:06:16] <SWPadnos> and readers
[00:06:23] <SWPadnos> those are always OK (or should be)
[00:07:00] <SWPadnos> if it's possible to hook a writer to an IO, it still may not work as expected
[00:07:32] <SWPadnos> many RT components that have output pins update every cycle, so they effectively force the signal to whatever value they want
[00:07:46] <SWPadnos> anyway, I don't know what I'm talking about here, so I should stop :)
[00:08:08] -!-
Mjolinor has quit [Remote host closed the connection]
[00:08:20] <SWPadnos> in any case, I think some of the conversions from parameter to pin may have errors
[00:09:03] <SWPadnos> incidentally, consider what happens when you change scale on the fly - the position will immediately jump, because the encoder component has an internal integer count, which it multiplies by the scale
[00:09:25] <SWPadnos> this is not (necessarily) the same value as whatever is on the UI display
[00:09:34] <andypugh> Yes, but in this case it is being used to close a spindle speed loop, so that is OK.
[00:09:49] <SWPadnos> ok, so it's to account for different gearing
[00:10:00] <andypugh> Yes
[00:10:06] <SWPadnos> then I suggest gearchange
[00:10:15] <SWPadnos> which is specifically intended for this
[00:11:05] <andypugh> gearchange only works for scaling the VFD command voltage, really. It still assumes that the encoder is on the spindle.
[00:11:27] <andypugh> (well, to be precise, it has nothing to do with the encoder)
[00:11:36] <SWPadnos> I hope these are fixed gears - not a vari-speed
[00:11:46] <andypugh> Yes, I think that they are.
[00:12:15] <SWPadnos> so you're closing the motor speed loop, not the spindle speed loop
[00:13:08] <andypugh> Hmm, yes, I guess you could use gearchange here, to convert spindle speed command to motor speed command.
[00:13:15] <SWPadnos> yep
[00:13:18] <andypugh> I will suggest that.
[00:13:33] <SWPadnos> ok
[00:13:48] <andypugh> I still contend that swapping parameters to IO pins was a bit unhelpful for many pins.
[00:13:57] <SWPadnos> I agree

[20:39:07] <micges> mhaberler: hi
[20:39:16] <mhaberler> hi micges
[20:39:24] <micges> re your question
[20:39:43] <mhaberler> I fugured that restriction is history.
[20:39:50] <mhaberler> works fine
[20:40:01] <mhaberler> or?
[20:40:18] <micges> it is not called from realtime task, from init module function
[20:40:32] <mhaberler> ah. sure.
[20:40:35] <mhaberler> duh...
[20:40:45] <micges> but probably it is history also
[20:41:03] <mhaberler> I only need it from initmodule
[20:41:15] <micges> may I ask with what are you messing?
[20:41:40] <mhaberler> yes
[20:42:04] <mhaberler> I'm playing with a kins module which does the z surface interpolation in the kins
[20:42:20] <mhaberler> inspired from the recent thread on pcb milling
[20:42:32] <mhaberler> with probe compensation of a warped surface
[20:42:44] <micges> ah
[20:43:43] <micges> I was thinking that you're making some changes to emcmot
[20:44:21] <micges> inspired by ja3 velocity problems :)
[20:44:22] <mhaberler> not yet ;)
[20:44:36] <micges> ok :(
[20:44:38] <micges> ok :)
[20:45:42] <mhaberler> no, I'm just taking a diversion from the other main branch - making interp truly instantiable, canon a abstract base class with emc/preview/sai instances, and task a class, too
[20:45:56] <mhaberler> very boring, but starts to twinker
[20:46:43] <mhaberler> when that's done comes the moment where I need to take a snapshot of motion state and switch to a separate task/interp instance
[20:47:01] <mhaberler> thats the mah approach to mdi-while-pause
[20:47:02] <mhaberler> d
[20:47:29] <micges> this will be super cool
[20:48:04] <mhaberler> I am a bit uneasy on the motion snapshot/restore stuff, the rest is relatively straightforward
[20:54:40] <mhaberler> it turned out that spinning out interp state (=butchering _setup) into 4 classes (world model, modal state, execution state, config) actually was just a day or so - so much about the 'we cant do this with existing developer time budgets'
[20:54:48] <mhaberler> canon took a few days so far
[20:55:55] <mhaberler> actually a very good cleanup exercise - there was gobs of state hidden here and there, and making it a class is a bit like dynamite fishing
