12:07 AM rue_shop3: oof the picture makes me want to build one
12:07 AM rue_shop3: http://bedair.org/Grizzly12x/BANDSAW.JPG
12:07 AM rue_shop3: uh, thats also the one I have, this thing is everywehre
12:07 AM * Tom_L got his blocks squared up to size and calls it a night
12:07 AM Tom_L: 11.4 x 2.4 x .825
12:07 AM rue_shop3: https://i.ytimg.com/vi/k1-v_ZQbgSM/maxresdefault.jpg
12:07 AM rue_shop3: same bandsaw, huh
12:07 AM rue_shop3: see how the rear jaw makes it impossable to use the whole cut width?
12:08 AM Tom_L: move it back
12:09 AM rue_shop3: the casting dosn't makes that easy
12:09 AM rue_shop3: it drops down
12:10 AM Tom_L: i'd rather have a vertical bandsaw
12:10 AM rue_shop3: https://images-na.ssl-images-amazon.com/images/I/81NE8h2bqrL._SL1500_.jpg
12:11 AM rue_shop3: I'd been told about this with it, but dont have the table
12:11 AM rue_shop3: iiintereting
12:11 AM Tom_L: looks a bit flimzy
12:12 AM rue_shop3: yea, the other ones were cast
12:12 AM rue_shop3: but their all on sites I cant brwose cause of the stupid 256bit key thing
12:12 AM rue_shop3: I cant update the browser cause I would lose the only copy of a working cad program I have (the new version dosn't do intersections properly)
12:13 AM rue_shop3: I like the black and orange, maybe its time for a rebuild :)
12:14 AM rue_shop3: add coolant and a proper lowering regulator
12:14 AM rue_shop3: (it uses a stupid adjustable spring)
12:41 AM rue_shop4: 1/12 HP motor, as large as a 1/2HP, and pulls 2.3A
12:41 AM rue_shop4: wtf?
12:48 AM rue_shop3: ok, to be fair, the normal size motor I was looking at is 1/20hp
12:49 AM rue_shop3: 62W motor
12:49 AM rue_shop3: 12V 5A, something seems wrong
12:50 AM rue_shop3: i suppose , cause its to pump flammable liquid, I shouldn't use a brushed motor
03:18 AM rue_shop3: but furrywolf a 1 track encoder with 3 sensors, can only get 8 positions
03:20 AM rue_shop3: with my idea, I can get 24 positions from 3 sensors
03:21 AM rue_shop3: thats 300%
03:21 AM rue_shop3: hmmm, 1 track is neat, but, for now, screw it
03:49 AM rue_shop3: seeign as its comming from a state machine, I wonder what the odds are I can lose the clock track and just wait for a valid next-code without getting errors
03:49 AM rue_shop3: from each code, there are only 2 valid next-codes, one for forward, one for reverse
03:51 AM rue_shop3: but even with using one track as a clock, 24 positions for 4 sensors is still pretty good
03:57 AM rue_shop3: Angle is: 0.000000 code is: 6 - 0 1 1
03:57 AM rue_shop3: Angle is: 15.000000 code is: 7 - 1 1 1
03:57 AM rue_shop3: Angle is: 30.000000 code is: 0 - 0 0 0
03:57 AM rue_shop3: Angle is: 45.000000 code is: 1 - 1 0 0
03:57 AM rue_shop3: Angle is: 60.000000 cod
03:57 AM rue_shop3: I can see that the odds of an error would be high
03:57 AM rue_shop3: if the bit timing weren't perfect
04:03 AM rue_shop3: ugh, 2am, and I want to write cam software
06:25 PM rue_shop3: furrywolf, its crude, but I have a cnc machine drilling an encoder disc right now
06:48 PM Tom_L: ok, if i can get drill clearance i may run P1 tonight
06:48 PM Tom_L: sitting on the vise presents it's own set of problems
06:51 PM rue_shop3: yar
06:51 PM Tom_L: did you get the memo on G0?
06:51 PM Tom_L: i'd swear you said grbl supported G10
06:53 PM Tom_L: it does...
06:53 PM Tom_L: that may not be what you were asking though
06:53 PM Tom_L: https://github.com/LaserWeb/deprecated-LaserWeb3/wiki/Supported-G-codes---GRBL
06:54 PM Tom_L: G10 L2, G10 L20: Set Work Coordinate Offsets
06:57 PM rue_: yea, I realized as I finished saying it
06:57 PM rue_: with G0
06:57 PM rue_: I split the code up and used G1
06:58 PM rue_: as long as i can set them to whatever the current position is, without knowing what it is, I'm good
06:58 PM rue_: "Zero is where you are now"
06:58 PM Tom_L: G10 will do that
06:58 PM Tom_L: i forget the difference in L2 and L20 though
06:59 PM rue_: what is it?
06:59 PM rue_: I havn't looked up G10 yet, but it said unsupported code
06:59 PM Tom_L: G10 L20 Set Coordinate System
06:59 PM Tom_L: G10 L20 is similar to G10 L2 except that instead of setting the offset/entry to the given value, it is set to a calculated value that makes the current coordinates become the given value.
07:00 PM Tom_L: so if you used P1 you would then use G54 in your code
07:04 PM rue_: p0 sounds like a good bet based on input files I'm not sure of
07:07 PM rue_: so, G10 L20 P0 xyz
07:07 PM rue_: no
07:07 PM rue_: so, G10 L20 P0 X0 Y0 Z0
07:07 PM rue_: "here is zero"
07:10 PM Tom_L: for G54 yes
07:10 PM Tom_L: no, P1 is for G54
07:10 PM Tom_L: P0 is for the 'active' work offset which by default _is_ G54
07:15 PM rue_: fireworks at 10:15
07:16 PM Tom_L: here too
07:16 PM Tom_L: we got a BB tournament goin on
07:18 PM rue_shop3: bed and breakfast?
07:19 PM Tom_L: base ball
07:19 PM rue_shop3: ah
07:19 PM Tom_L: minor league
07:23 PM Tom_L: router reset... pls standby
