10:10 AM Tom_L: useless knowledge: end of year date is 123123
10:21 AM Tom_L: i fixed the leadin/out on the model :)
10:21 AM Tom_L: i should use arcs all the time but usually don't take the time
10:30 AM rue_mohr: cool
10:30 AM rue_mohr: still Pointer.txt?
10:32 AM Tom_L: yeah
10:32 AM Tom_L: i was fiddling with making a metric one for 1mm bit
10:33 AM Tom_L: i cut mine in 2 parts though. no stickum tape
10:33 AM rue_mohr: Oooo
10:33 AM Tom_L: first half and hole, clamp then 2nd half
10:33 AM rue_mohr: I'd like to get a better pointer, I'm otherwise working on the rest of the parts
10:33 AM Tom_L: you got a 1mm bit?
10:34 AM rue_mohr: yes, thats what I used
10:34 AM Tom_L: i'll see what comes of this
10:34 AM Tom_L: but you don't have a means to clamp
10:35 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/pointer/Pointer_fixture.jpg
10:35 AM Tom_L: part 2
10:35 AM rue_mohr: oh idea
10:36 AM rue_mohr: do you have a link for a clamp thats close to the ones your using?
10:36 AM Tom_L: those are sherline clamps
10:37 AM Tom_L: then i made some steel ones
10:37 AM Tom_L: 3/16" slot i think
10:37 AM Tom_L: 10-32 screw
10:37 AM rue_mohr: I'd like to 3d print up some of those clamps
10:37 AM rue_mohr: ok
10:37 AM rue_mohr: 1/2" wide?
10:47 AM rue_mohr: 2" long?
10:47 AM Tom_L: approx
10:47 AM Tom_itx: https://www.sherline.com/product/3012-standard-hold-down-set/#description
10:47 AM Tom_L: i should make a model and make some
10:47 AM rue_mohr: ooo
10:47 AM Tom_L: mine i put a screw on the back to adjust the height
10:47 AM rue_mohr: yea
10:47 AM Tom_L: works better than the step thing
10:47 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A8_new/A8%20profile2.jpg
10:47 AM Tom_L: that long one has a threaded hole on both ends
10:47 AM Tom_L: just random cutoff from building the mill
10:47 AM rue_mohr: mmm
10:50 AM Tom_L: oh
11:02 AM rue_mohr: trying to design the bit that holds the servo/needle
11:03 AM Tom_L: got a file for you
11:03 AM rue_mohr: OOo
11:04 AM Tom_L: your thing won't like some of the code
11:04 AM rue_mohr: I know to look for the adjustments
11:05 AM rue_mohr: I need to make my spooler more instruction aware
11:05 AM rue_mohr: I'd like it to be able to do adjustments of the feed rates in the file
11:05 AM rue_mohr: but being aware of multiple commands on the same line is important too
11:07 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/pointer/Pointer_path.mp4
11:08 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/pointer/Pointer_M.txt
11:08 AM Tom_L: _M
11:08 AM Tom_L: metric
11:08 AM Tom_L: i hope
11:09 AM Tom_L: but your thing won't like the op stops and (text inside parenthesis)
11:09 AM rue_mohr: hmm, I suppose adding breakpoints to my spooler would be good too
11:10 AM rue_mohr: ok
11:10 AM Tom_L: if you don't want the op stops i can remove them and post another txt
11:10 AM rue_mohr: thats for 2k rpm?
11:10 AM Tom_L: that's what it says
11:10 AM Tom_L: read the S word :)
11:10 AM rue_mohr: hah, right
11:11 AM Tom_L: i'll post one without the stops but you do need one stop to move the clamp
11:11 AM Tom_L: so that won't work either
11:11 AM Tom_L: does grbl use M0?
11:11 AM rue_mohr: it might
11:11 AM rue_mohr: I'v never tried
11:11 AM rue_mohr: I can test
11:11 AM Tom_L: try it once and see
11:11 AM Tom_L: you may need to remove the ()
11:12 AM Tom_L: 3x i think
11:12 AM rue_mohr: I'll try it and see
11:12 AM rue_mohr: I think it uses ! for resume
11:12 AM rue_mohr: and I can inject
11:12 AM Tom_L: clamp close to the part so the cd doesn't pull up
11:12 AM rue_mohr: yup
11:13 AM Tom_L: a bit closer than my pic
11:13 AM rue_mohr: it was trying when I was doing the other cuts
11:13 AM Tom_L: but the mp4 shows the path
11:13 AM rue_mohr: I might have to make some clamps first
11:14 AM Tom_L: the video shows it cutting too much because i didn't save the cutter data for metric
11:14 AM rue_mohr: I'm having a time working out a way to hold the needle shaft
11:14 AM Tom_L: do it like i did
11:14 AM rue_mohr: yea
11:15 AM Tom_L: thin strip of aluminum
11:15 AM rue_mohr: I need some plastic clamps
11:15 AM Tom_L: and if it cuts it so what
11:15 AM rue_mohr: how long is the cutter edge of your 1/16?
11:15 AM Tom_L: .125
11:15 AM rue_mohr: fraction .125
11:16 AM rue_mohr: Best Match for 0.125000, is 1/8 (0.125000)
11:16 AM rue_mohr: Error is 0.000000
11:16 AM rue_mohr: thats a LOT shorter than mine
11:16 AM Tom_L: well you only want enough to cut the material especially on small bits
11:16 AM Tom_L: that is long compared to some
11:17 AM rue_mohr: yea, mine are pcb drills, so the cut edge is about 7-9mm
11:17 AM Tom_L: just don't let the plastic ball up on it or it'll snap
11:17 AM rue_mohr: its been ok so far
11:17 AM Tom_L: those feeds worked good here
11:17 AM rue_mohr: did you do conventional or ?
11:17 AM Tom_L: S2000 F6 plunge F3
11:17 AM rue_mohr: k
11:18 AM Tom_L: i dunno i did what would work for holding it
11:18 AM Tom_L: 1" above the part top is zero
11:18 AM rue_mohr: hmm, I'm not sure what my z's look like on this part
11:18 AM Tom_L: or you'll poke a hole in your table
11:19 AM rue_mohr: oh yea the 1"!
11:19 AM rue_mohr: havn't had a crash in a LONG time
11:19 AM Tom_L: rather important feature
11:19 AM rue_mohr: I used to be able to a disconnect/reconnect to reset the machine (0,0,0) but the new one cant do that
11:20 AM rue_mohr: there is an M? code, and I dont remember what it is
11:20 AM Tom_L: for what?
11:20 AM Tom_L: M0 M1 are op stops
11:20 AM Tom_L: one is with a switch to enable it
11:20 AM Tom_L: otherwise it's ignored
11:21 AM Tom_L: M1 - pause a running program temporarily if the optional stop switch is on.
11:22 AM rue_mohr: I can do a little test between two lines and see if the machine does a stop
11:22 AM Tom_L: use M0
11:22 AM rue_mohr: just trying to design this mechanical baseplate right now...
11:22 AM Tom_L: eliminates the physical switch
11:23 AM Tom_L: oh..
11:23 AM Tom_L: i didn't convert the feed
11:23 AM Tom_L: you may want to bump that up
11:23 AM Tom_L: F6 may be too slow for yours
11:23 AM Tom_L: convert 6 ipm to mm/m
11:24 AM rue_mohr: heh
11:24 AM Tom_L: and the z feed is 3
11:24 AM Tom_L: 3-4 places
11:24 AM rue_mohr: you have some time if you want to adjust
11:24 AM rue_mohr: I still need to have breakfast, and a shower, and I want to work out this other plate design
11:25 AM Tom_L: 152mm/m
11:25 AM Tom_L: right?
11:25 AM rue_mohr: 50mm/min iirc
11:25 AM rue_mohr: maybe you used faster
11:25 AM Tom_L: also change the G20 to G21
11:25 AM rue_mohr: overflow :)
11:25 AM Tom_L: all i did was adjust the path for your smaller cutter
11:26 AM rue_mohr: I better start breakfast, lunch will sneak up fast on me
11:26 AM Tom_L: G20 is the first line
11:27 AM Tom_L: i changed that
11:27 AM Tom_L: you want 50mm/m ?
11:29 AM Tom_L: feeds adjusted now too
11:32 AM rue_mohr: 50 seemed like it could have been too slow, did your rate convert to 150?
11:32 AM rue_mohr: sounds pretty high
11:32 AM rue_mohr: I think my machine there tops out at 300mm/min
11:32 AM rue_mohr: much above that and it starts dropping steps
11:33 AM Tom_L: i ran it at 150mm/m
11:33 AM Tom_L: 6 ipm
11:33 AM rue_mohr: ok
11:33 AM Tom_L: so is that what you'd like?
11:33 AM rue_mohr: I need to get the mister working too
11:33 AM Tom_L: yes you do
11:33 AM rue_mohr: well, I'd feel ok with like 100, but 150 feels scary
11:33 AM Tom_L: you don't have feed override on yours do you?
11:33 AM rue_mohr: not yet
11:34 AM Tom_L: i'll change them to 100 then
11:34 AM rue_mohr: I can edit the file in my spooler tho
11:34 AM rue_mohr: how many lines is the feed rate on?
11:35 AM rue_mohr: I'm gonna need to remember which things to edit tho
11:35 AM Tom_L: F100 now
11:35 AM Tom_L: plunge is 50
11:35 AM rue_mohr: ok
11:36 AM Tom_L: does grbl use G53?
11:36 AM Tom_L: (machine home) not G54 fixture offset
11:36 AM Tom_L: i use G54 fixture offset in mine
11:37 AM rue_mohr: I dont know...
11:37 AM rue_mohr: 1 min
11:38 AM rue_mohr: or longer, browser is being slow
11:39 AM Tom_L: hmm, i have a grbl post, maybe i should have used it
11:39 AM Tom_L: i was working on that a while back
11:39 AM rue_mohr: https://www.sainsmart.com/blogs/news/grbl-v1-1-quick-reference
11:39 AM rue_mohr: yup
11:41 AM Tom_L: but do you zero your machine when you start it?
11:41 AM rue_mohr: ok I'v worked out, I think, how to do the needle shaft support
11:41 AM Tom_L: and set G54 offset
11:41 AM rue_mohr: yes, I set machine 0,0,0 and work 0,0,0 to the 0,0,0 of the job
11:41 AM Tom_L: i have world home and G54 zero
11:42 AM rue_mohr: maybe thats the command I was using
11:42 AM Tom_L: world home defines the zero for the machining box size
11:42 AM rue_mohr: I had a command that set the current location to work 0,0,0
11:42 AM Tom_L: probably. default for that is G54
11:43 AM rue_mohr: I dont do a machine 0, I always manualy put 0 at the point I want on the work and make sure the work fits on the material
11:43 AM Tom_L: that _should_ be ok
11:45 AM rue_mohr: ah yes, ok, if I make a retainer I can use the head of the pin as a second retainer
11:45 AM rue_mohr: maybe the pulley can double-duty...
11:47 AM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/main.png
11:47 AM rue_mohr: complex little beast
11:47 AM Tom_L: :)
11:51 AM rue_mohr: this is requiring me to do prints just to fully visualize everything
11:57 AM rue_mohr: ok, layer 500, I think its ready
11:57 AM rue_mohr: (part 5)
12:41 PM rue_mohr: ok!
12:41 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/clamp.png
12:41 PM rue_mohr: ;]
12:42 PM rue_mohr: the printer isn't done that last part, I guess I need to fire up another one
12:52 PM Tom_L: hah
12:53 PM Tom_L: now, make a long reach one
12:53 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A8_new/A8%20profile2.jpg
12:53 PM Tom_L: those are handy too
01:10 PM Tom_L: did you ever get that clamp set you were looking at?
01:15 PM Tom_L: https://grabcad.com/library/t-slide-clamp-set-machining
01:16 PM Tom_L: i like the screw better than the steps
01:17 PM rue_mohr: I think I decided to make them
01:20 PM rue_mohr: ok, the meter part printed
01:20 PM rue_mohr: I can do some size adjustments
01:38 PM Tom_L: new file ran ok.. pics to come
01:41 PM Tom_L: point is better
01:43 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/pointer/Pointer_3.jpg
01:44 PM Tom_L: leadin/out better
01:47 PM rue_shop2: :)
01:47 PM Tom_L: that's the file i posted
01:47 PM Tom_L: inch
01:47 PM Tom_L: and yours should be the same in mm
01:48 PM rue_shop2: oh, my machine can do inch
01:48 PM rue_shop2: its ok with the G~ for metric/imperial
01:48 PM Tom_L: but do you have a 1/16" cutter
01:48 PM Tom_L: if so, run that one
01:48 PM rue_shop2: no, but I do have 1.5mm, do you think its close enough?
01:49 PM Tom_L: 1/16 - .0625 1.5mm - .0591
01:49 PM Tom_L: no
01:50 PM Tom_L: the hole would be small and the pointer would be fatter
01:50 PM Tom_L: .003
01:50 PM Tom_L: you can try i guess
01:50 PM rue_shop2: o and more importantly the hole
01:51 PM Tom_L: and you're not gonna ream the hole out :)
01:51 PM rue_shop2: think I have a steady enough hand to cut a milling end on a drillbit?
01:51 PM Tom_L: no
01:51 PM Tom_L: not center cutting
01:53 PM rue_mohr: I'm still waiting for clamps to print
01:53 PM rue_mohr: then I'd have to re-level my bed, the wood warped :]
01:55 PM rue_mohr: huh
01:55 PM rue_mohr: not quite sure what happened to my 1/2"...
01:56 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1290299.jpg
01:56 PM rue_mohr: huh, but longer than 2" too
01:57 PM rue_mohr: bit more than 2.5"...
01:57 PM rue_mohr: hahha
01:57 PM rue_mohr: well, it only took a few minutes to design anyhow...
02:41 PM rue_shop2: trying to set up a casting mold and it WILL NOT go
