04:39 AM Tom_L: deflection
06:05 AM rue_mohr: hmm
06:05 AM rue_mohr: more speed?
06:05 AM rue_mohr: rpm
06:19 AM Tom_L: rpm is ok i think
06:20 AM Tom_L: just a small part and the cutter is moving it
06:22 AM rue_mohr: shall I try a 1.5mm bit?
06:24 AM Tom_L: probably do the same thing
06:24 AM Tom_L: try cutting the other direction :)
06:24 AM rue_mohr: I did conventional
06:25 AM Tom_L: it'll either be worse or better
06:25 AM Tom_L: offset the cutter .005"
06:58 AM rue_mohr: I'll try it later today
07:25 AM Tom_L: i think mine was a bit thin too
05:30 PM rue_mohr: the cutting length of my bits is long
05:31 PM rue_mohr: thought I could kinda see if deflecting
05:49 PM Tom_L: could also be the plastic heating cooling shrinking when the cutter goes by
06:34 PM rue_mohr: same with and without coolant
06:42 PM Tom_L: my coolant made a huge difference
06:43 PM rue_mohr: k
06:44 PM rue_mohr: one of the twitter folk did a faceplate from my dxf in freecad and beveled the edges for me :]
06:44 PM rue_mohr: freecad looks like a bit of a mess
06:44 PM rue_mohr: so I'll go back to that later
06:53 PM Tom_L: it's getting better but very slow
06:57 PM Tom_L: made a part or made a model for you?
07:12 PM rue_mohr: took that dxf and made the faceplate
07:12 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/main.png
07:12 PM Tom_L: my gcode is there if you wanted to try it but it's for a 1/16" cutter
07:12 PM rue_mohr: with the bevels
07:12 PM rue_mohr: ooo
07:12 PM rue_mohr: not sure if I have a 1/16
07:13 PM Tom_L: zero is the hole
07:13 PM rue_mohr: I cant so the darn bezels like that in openscad
07:13 PM Tom_L: it's made for clamps and doesn't do the leadin leadout quite right
07:13 PM Tom_L: ahh
07:13 PM rue_mohr: gradually the parts are stacking up for this
07:14 PM rue_mohr: I need to work out how to make a 9g servo turn the needle
07:14 PM rue_mohr: I think I'll be able to work soemthing out :]
07:16 PM rue_mohr: after me trying to specify a size accurate sticker, I think the sticker company is too frustrated with me
08:53 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1290291.jpg
08:53 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1290292.jpg
11:21 PM rue_mohr: main gear 20mm
11:21 PM rue_mohr: spur gear 2.4mm
11:21 PM rue_mohr: not gonna find that spur...
11:27 PM rue_mohr: oh no, that wont work
11:27 PM rue_mohr: the hobby servo can only move like 180 degrees
11:27 PM rue_mohr: So I need to make sure I'm 2:1 at worst (needle range is 90 degrees)
