07:42 AM Tom_L: hi
08:21 AM rue_mohr: morning
08:22 AM Tom_L: got all ready to go and my first job has covid so no thanks
09:13 AM rue_mohr: going around down there eh?
11:12 AM Tom_L: seems so
05:11 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/mount/Rotary_mount8.jpg

05:11 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/mount/Rotary_mount12.jpg
07:40 PM rue_mohr: nice
07:44 PM Tom_L: worked out ok
07:48 PM rue_mohr: so its just software now
07:48 PM rue_mohr: and a good strain relief for the motor
07:48 PM Tom_L: well i need another driver
07:48 PM rue_mohr: oh
07:49 PM Tom_L: i did wire the cabinet for it though for the most part i think
07:49 PM rue_mohr: getting pretty crowded
07:49 PM Tom_L: i'm just not sure of all the signal wires if i had to use them for something else or if i reserved them for A
07:50 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.1/New_Mill_IO_Pinout.pdf
07:52 PM Tom_L: i don't see step/direction for 3
07:52 PM Tom_L: 0 is X 1 is Y 2 is Z so 3 is A
07:55 PM Tom_L: yeah i have no step/direction for A
08:11 PM Tom_L: yeah, the firmware doesn't have step/dir for A axis
08:12 PM Tom_L: i'd have to figure that out and i dunno if i have pins for it
08:15 PM Tom_L: ok i need 3 pins and i'm not sure i can come up with 3
08:18 PM Tom_L: ok i did reserve ENA-A
08:22 PM Tom_L: ok this is gonna be a big mess
08:35 PM rue_mohr: wait, where does the fpga stop?
08:35 PM Tom_L: what do you mean?
08:35 PM rue_mohr: does the fpga support the A axis?
08:36 PM Tom_L: most of the wiring is thru a daughter card and it's full
08:36 PM Tom_L: the rest in unprotected
08:36 PM Tom_L: i have some limits running thru the unprotected part
08:36 PM rue_mohr: so, the fpga has signals for it, but not the buffer card?
08:36 PM Tom_L: some of this isn't making sense
08:37 PM Tom_L: one sec
08:37 PM rue_mohr: computer -> fpga -> buffers -> drivers -> motors
08:37 PM rue_mohr: yes?
08:38 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.1/7I90_pinout.txt
08:38 PM Tom_L: those are the signals currently on the fpga with IO numbers
08:38 PM Tom_L: if you look at the pdf with the IO numbers some of them aren't making sense
08:39 PM Tom_L: i need to double check and figure out what is going on
08:39 PM Tom_L: i thought i had the pdf all up to date
08:39 PM rue_mohr: ITS DEFINITLY ONLY 3 AXIS
08:39 PM rue_mohr: ASF
08:39 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.1/New_Mill_IO_Pinout.pdf
08:39 PM rue_mohr: stupid caps again
08:39 PM Tom_L: yeah but i can add the function to the fpga i just need pins to put it on
08:39 PM Tom_L: and i don't think i have any
08:40 PM Tom_L: but if you map step/dir some aren't making sense
08:40 PM Tom_L: and i'm not sure about the enables
08:40 PM Tom_L: i know i'm using them but i need to figure out where they come from
08:41 PM Tom_L: i know they're all wired together on the control thru a relay
08:47 PM Tom_L: i know the txt file is right because i just went out and got it off the mill
08:49 PM rue_mohr: you have an opto isolator in there too dont ya?
08:49 PM Tom_L: to the relay
08:49 PM Tom_L: for the enable
08:49 PM rue_mohr: I mean for hte xyz
08:50 PM Tom_L: it's part of the daughter card
08:50 PM Tom_L: all io on it are isolated
08:51 PM Tom_L: i _think_ i might be using the spindle enable for them all
08:51 PM Tom_L: so that's not a big deal
08:54 PM Tom_L: i could use the SSerial because i'm not using that right now
08:57 PM rue_mohr: oh yea, I'm supposed to be working on a cnc tooo
09:15 PM Tom_L: which one?
09:15 PM * rue_mohr rolles eyes
09:15 PM rue_mohr: does it matter?
09:15 PM Tom_L: heh
09:15 PM rue_mohr: so,
09:16 PM rue_mohr: I got the source to kompozer
09:16 PM rue_mohr: and found out I need gnome-vfs
09:16 PM rue_mohr: which wasn't available
09:16 PM Tom_L: don't get distracted fixing that now :)
09:16 PM rue_mohr: so I got the source for that
09:16 PM rue_mohr: and now gnome-vfs needs libbonobo2, which isn't available
09:17 PM rue_mohr: if I stay on this path, something with loop back around for a circular dependency
09:17 PM rue_mohr: it might take days to find
09:20 PM rue_mohr: I'm in my pajamas, I shouldn't do machining
09:20 PM Tom_L: barefoot too?
09:20 PM rue_mohr: stray chaff could be detremental
09:20 PM rue_mohr: yea
09:20 PM rue_mohr: thats not as much a problem if the shavings are cool
09:21 PM rue_mohr: I also want to try doing encoders again, I have my and your awesome wheels to start with this time
09:21 PM Tom_L: how many did i give you?
09:22 PM Tom_L: i nearly forgot about those
09:22 PM rue_mohr: about a dozen wasn't it?
09:22 PM Tom_L: no idea
09:22 PM rue_mohr: and I printed and painted a ton of them
09:22 PM rue_mohr: I did a cnc file for the base disc
09:23 PM rue_mohr: but got hung up on making a threaded coller like a pot has
09:23 PM rue_mohr: I should just tear apart old pots!
09:23 PM rue_mohr: got tonnes of 'em
09:24 PM rue_mohr: hmm or work out how to use lamp pipe
09:24 PM rue_mohr: is that even the same scale?
09:44 PM rue_mohr: hahah
09:44 PM rue_mohr: the dependency after the dependency after that, requires me to remove the program I'm trying to compile
09:46 PM rue_mohr: bison -y -d -v 2>/dev/null ./parser.y
09:46 PM rue_mohr: Makefile:723: recipe for target 'stamp-parser' failed
09:46 PM rue_mohr: make[1]: *** [stamp-parser] Error 1
09:46 PM rue_mohr: make[1]: Leaving directory '/files/programming/src/kompozer/libIDL-0.8.3'
09:46 PM rue_mohr: Makefile:476: recipe for target 'all-recursive' failed
09:46 PM rue_mohr: make: *** [all-recursive] Error 1
09:47 PM rue_mohr: crash bang bonk
09:48 PM Tom_L: heh
09:51 PM rue_mohr: zippo:/files/programming/src/kompozer/libIDL-0.8.3# bison -y -d -v ./parser.y
09:51 PM rue_mohr: ./parser.y:610.9-10: error: $$ for the midrule at $6 of 'struct_type' has no declared type
09:51 PM rue_mohr: $$ = IDL_type_struct_new ($4, NULL);
09:51 PM rue_mohr: ^~
09:51 PM rue_mohr: ./parser.y:627.9-10: error: $$ for the midrule at $10 of 'union_type' has no declared type
09:51 PM rue_mohr: $$ = IDL_type_union_new ($4, $7, NULL);
09:52 PM rue_mohr: and I wonder why I get nothing done after work
09:55 PM Tom_L: this might end up being more trouble than it's worth for what little if even i use it
09:56 PM rue_mohr: I need to make a trash compactor
09:57 PM rue_mohr: I'm not quite sure how far I should take it
09:57 PM rue_mohr: auto-bailer?
10:20 PM Tom_L: the daughter card kinda limits what i can do with the IO
10:21 PM Tom_L: i found 1 output but i need 2
10:22 PM Tom_L: i got 0 - 7 outputs and all but one is used
10:24 PM Tom_L: 0-Zstep, 1-Zdir, 2-available, 3-E-Stop out(enable relay), 4-Xstep, 5-Xdir, 6-Ystep, 7-Ydir
10:27 PM Tom_L: IO 16, 17, 18 are for the spindle AUX, DIR, ENA
10:27 PM Tom_L: i wonder if i could use AUX
10:27 PM Tom_L: maybe move estop to it and free up a TX pin
10:28 PM Tom_L: and it's opto isolated and can be + or -
10:29 PM Tom_L: haha i might be able to pull that off
10:33 PM Tom_L: nope, that's the spindle brake
10:33 PM Tom_L: i'm lacking 1 io
10:33 PM Tom_L: output
10:39 PM rue_mohr: hmm
10:39 PM rue_mohr: but not the fpga, just eh daughter card?
10:43 PM rue_mohr: I'm processing the hearing tests I did on ma and a scattering of other people
10:43 PM rue_mohr: trying to understand the results
10:44 PM rue_mohr: so, the higher the number, the worse the hearing
10:44 PM rue_mohr: :
10:45 PM rue_mohr: my left ear, about 75
10:45 PM rue_mohr: my right ear about 190
10:45 PM rue_mohr: second test, left ear, about 100
10:45 PM rue_mohr: second test, right ear, about 140
10:46 PM rue_mohr: ma, left ear, 2000
10:46 PM rue_mohr: second test, left, about 1250
10:46 PM rue_mohr: ma, right ear, about 900
10:47 PM rue_mohr: second test, right ear, about 500
10:47 PM rue_mohr: moons kid, left ear, about 125
10:47 PM rue_mohr: moons kid, right ear, about 75
10:47 PM rue_mohr: moon, left ear, about 45
10:48 PM rue_mohr: moon, right ear, about 50
10:49 PM rue_mohr: so, it looks like about 100 is fine hearing
10:49 PM rue_mohr: I have a weak right ear
10:50 PM rue_mohr: ma, needs her hearing boosted by about...
10:50 PM rue_mohr: 5x - 20x
