cradek: huh I remember a problem with toolchange and FPR but I thought I had fixed it
cradek: guess not
jepler: if you turn OFF fpr before the tool change, the bug happens. if you leave it on, the tool change works fine
I could find the problem in 5 minutes so I hacked my gcode and continued making parts
I can get you the program if I left the machine on - let me check
I think I wrote a program here that demonstrates the problem

if you take away line 5 does it work?
that's it then
I have a second symptom, let me isolate it
but if I remove the (G94) it stops on the next G1 (because the spindle's not spinning)
not an error, just zero feed rate
[14:08:14] <cradek> http://timeguy.com/cradek-files/emc/440.ngc
looks like the interpreter doesn't know that M6 toolchange stops the spindle turning
in 440.ngc the G0 on line 31 goes slow
emc latency test: http://pastebin.ca/655938
the intervals between thread invocations are systematically a little bit too close together (an averge of 4ns too soon); the worst interval on the fast thread was 29511ns compared to requested 24305ns
yeah those numbers should all be in nanoseconds
assuming that's what rtapi_get_time() returns
I think there was something bad about rtapi_get_time() :?
yeah it takes a long time
* alex_joni vaguely remembered something
doesn't matter much in this case

I'm not sure I'm measuring quite the same as the rtai latency test but with a few tweaks I will be
jepler: very cool
jepler: hope one of these days it'll say replace your <mumblesomething> because it's the one causing bad latencies :D
alex_joni: keep dreaming!
a nice list of your hardware and what latency each is contributing. ;)
like.. oops a bigger latency.. what did you just do? oh, you plugged in a keychain.. please stop doing that!
oh, the users keeps insisting.. /etc/init.d/hotplud stop
good night all
bridgeport update: it is safely on the driveway
now I have to make it shorter, then make a ramp to roll it into the garage, then make it taller again
we have moved a lot of heavy equipment on inch waterpipe.
yep that's the plan
but, it's too tall, that's the hard part
also there's a 2" step up
got some steel plate to make a ramp with
and a heavy duty comealong
nice - some sort of comealong?
fortunately there's a tree in the right place to pull on! (through the back door of the garage)
very nice. We would drill holes in the concrete floor around the edged for pull points.
that's a good idea too
if you don't mind the holes. :)
the correctly placed tree is a very nice surprise - I hadn't thought of it until just seeing it today
if I protect it with something it will be fine - it's a huge tree
do you have some sort of cherry picker to take the top off?
I have a forklift until 8am
I really wish I had the manuals to see how the spindle housing comes apart, but I don't have them yet
that should work :) just be careful. I would think a car pulling strap - kinda like a seatbelt style (2inches wide) would work for the tree
yeah I only have a chain right now, but I can go get more stuff
