[Emc-users] polyurethane resin casting

Has anyone here done much polyurethane resin pouring? I have been trying to fine tune the process. Current process uses silicon moulds. #1. Does it work to use aluminum moulds? #2. Could it work to use high vacuum to eliminate air bubbles? I would envision using some type of fill funnel and

Re: [Emc-users] Plastic button routing

Hmm. I wonder how many folks who own a cnc router would let somebody else do something like this? My bro-in-law has a laser engraver, but to get a paintable depth would take a lot longer than the 20 seconds per but its taking me. So the suggestion is that a v bit is not going to curl the edges t

[Emc-users] Plastic button routing

I am routing some lettering on some small plastic buttons with a .020 ball nose feeding at 15 ipm. I am using vcarve pro to create the lettering, using Norm West 1L, or a single line font. I am using create profile, on, to route the line, and doing two passes, one conventional, one climb, in an a

Re: [Emc-users] Adjusting Work Coordinates and Offsets?

This takes some special work for your g code, but I have done something remotely similar. What I did was use the G54-59 offset system and G file subroutines called from pyvcp. If I have this straight in my mind what you are doing, it would be something like this. 1. Home to G54 x,y, and z. 2. P

Re: [Emc-users] Button paint and engraving

I don't see an easy way to make multicolored silicon rubber buttons, though. I shouldn't even open my mind to doing silicon, its one of those things that is tempting though. I guess I could try making my own buttons with translucent black acrylic. I am stuck using something that will fit on top o

[Emc-users] Button paint and engraving

I painted some of these http://www.digikey.com/product-detail/en/1WD16/679-2144-ND/2034700 buttons today, and engraved them, but find that the paint is not curing like I would like (not very durable), and the paint is soft enough that they did not engrave very nice. Not only that, these are backli
