14:59:38 <rayh-away> Hi guys.
14:59:59 <rayh-away> rayh-away is now known as rayh
15:00:13 <rayh> I'll take a minute to update the wiki diary.
15:00:14 <alex_joni> morning rayh
15:00:31 <rayh> alex.  The mods you did for spindle reversing work great.
15:00:39 <alex_joni> glad to hear that
15:00:53 <rayh> Life is good.
15:01:04 <alex_joni> * alex_joni is tired :(
15:01:14 <alex_joni> think I went to bed too early last night
15:01:24 <rayh> We stuffed a tool into the magazine last night.
15:01:33 <alex_joni> cool
15:01:48 <rayh> Was able to load it into the transfer arm and from there to under the spindle.
15:02:03 <rayh> I need to change spindle orientation and then we should be able to
15:02:09 <rayh> manually change tools.
15:02:17 <rayh> Next is the ladder for that.
15:02:35 <rayh> Does iocontrol forward the tool prepare message.
15:02:48 <rayh> if so, how do we handle the pocket number?
15:03:08 <rayh> You tirred from to much sleep?
15:06:17 <alex_joni> probably
15:06:20 <alex_joni> hang on a bit
15:06:25 <alex_joni> * alex_joni is busy 10 mins
15:07:57 <rayh> No problem.  I just fired up the machine.
15:12:34 <alex_joni> you need to tell me how tool changing works now in hal
15:12:49 <alex_joni> got some pins for the different tools?
15:12:57 <alex_joni> or a pin that tells what tool to load?
15:13:05 <alex_joni> I can then add the stuff to iocontrol.
15:17:49 <rayh> Okay.  I'll have to think on this for a bit.
15:18:23 <rayh> I believe that the tool prep NML passes the number of the next tool's pocket.
15:18:28 <alex_joni> yes
15:18:34 <alex_joni> and that reaches iocontroller
15:18:42 <alex_joni> which should just turn on some hal-pins
15:18:52 <rayh> In this case it would be a number between 0 and 24
15:18:57 <alex_joni> but either one hal-pin for each tool (which is a lot)
15:19:06 <alex_joni> but maybe other machines would want more tools?
15:19:25 <rayh> The location of the magazine is handled by five prox switches.
15:21:24 <rayh> They are labeled 2 to the power of 0
15:21:30 <rayh> 2 to the power of 1
15:21:44 <rayh> 2 to the power of 2
15:21:55 <rayh> 2 to the power of 3
15:21:58 <alex_joni> I see.. so some basic decoding
15:22:16 <rayh> They read holes in the steel ring that holds tools.
15:22:40 <alex_joni> ok I suggest a small hal-module then
15:22:45 <alex_joni> specific for this job
15:23:01 <alex_joni> because ladder for this might be very big
15:23:11 <rayh> Then there is a magazine in position prox
15:24:38 <alex_joni> * alex_joni goes home
15:24:46 <alex_joni> back in 30 mins I think
15:24:52 <rayh> k
15:25:00 <alex_joni> think about it :)
15:25:04 <alex_joni> * alex_joni will do that too

23:35:42 <CNC_Workshop> Okay.  We have changed tools!
23:35:53 <CNC_Workshop> Now we have a lot of work to do.
23:36:42 <CNC_Workshop> I need to add a stack of prox switches to the HAL.
23:37:22 <CNC_Workshop> Then I need to link them to cl.
23:38:11 <CNC_Workshop> The NML tool prep message delivers a next tool number.
23:38:39 <CNC_Workshop> Need to compare that number to current position
23:39:17 <CNC_Workshop> and select the shortest direction magazine-forward or magazine-reverse
23:39:41 <CNC_Workshop> and count up or down to reach the needed tool.
23:44:03 <CNC_Workshop> roland manufactured a small "tuning fork" looking tool to sit in the tool holder notch and, with the spindle off, rotate the spindle dog into it.
23:45:16 <CNC_Workshop> Then we could read the spindle encoder position, and enter that value into the ini file's ORIENT_POSITION.
23:45:26 <CNC_Workshop> Worked like a charm the first time.
23:52:23 <CNC_Workshop> Wrote a small tickle script with buttons to speed up the reaction time.
