It is good when you have big machine for mdf or acrylics. For this machine, strong stepmotors with current choppers and microsteps driver will be enough + ubuntu emc2 and that is all. Here http://www.youtube.com/watch?v=PmewmV87Lcg&feature=player_detailpage is an example of modernization old mill to cnc with usage of emc2 and steppers.<br /><br />Think about vacuum holder with rubber gasket like this: http://www.youtube.com/watch?v=9K9ylKWUHKE&feature=player_detailpage it doesn't need to be this hight but it is helpful when you cut throw the material.<br /><br />Greatings!syntetyczny drańhttps://www.blogger.com/profile/11627951722238785207noreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-51882552290815655872011-08-26T21:29:57.909-07:002011-08-26T21:29:57.909-07:00I wish I had thought of this when I was cutting a ...I wish I had thought of this when I was cutting a IR filter very similar to what you have there, only thinner. <br /><br />Looks like you have a Erickson Quick-change spindle.<br /><br />Don't get the Ajax. I have heard nothing good about it. There are several options out there for retrofitting and keeping the existing servos and drives. I have done several retrofits/builds and recently installed new servos on my mill:<br /><br />http://www.youtube.com/watch?v=nmdSIzvh3gI&feature=feedwll&list=WLmaconahttps://www.blogger.com/profile/05197912018566854002noreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-36549951876984234012011-08-26T19:42:00.937-07:002011-08-26T19:42:00.937-07:00David, I use double-stick tape very often for mach...David, I use double-stick tape very often for machining plastic plates. It works great, but often the coolant will cause the tape to come loose, so it's best used dry. Also, as you anticipated, getting the mirror or glass off the tape is sometimes a big problem (if it doesn't come loose due to coolant seepage). Seems contradictory, I know.<br /><br />I've never used a vacuum chuck (what you described in #2), but I would like to. It requires careful setup so that unused holes are plugged and air doesn't leak in. It gets a lot more difficult when using a cutting fluid, but still possible with a fluid trap. Vacuum chucks work well with paper-mask plastics like acrylic. It's possible to program the depth of cut so precisely that the plastic is cut through, but the protective paper mask is left intact, providing a seal for the vacuum system.Ben Krasnowhttps://www.blogger.com/profile/04234629396863486242noreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-2920599882657087652011-08-26T15:08:29.748-07:002011-08-26T15:08:29.748-07:00Ben-

If the adhesive is an issue (breaking the glass trying to remove it), you could also (idea #2) have a thin film of soft material with a high coefficient of friction (but not adhesive) to put between the glass and mount. drill holes in the mount as air passages, and then get a shop-air powered vacuum generator to draw a vacuum on the passages. The glass would be held on by the pressure differential.Davidhttps://www.blogger.com/profile/12337076696758796542noreply@blogger.comtag:blogger.com,1999:blog-401164737462963207.post-65798818233881880532011-08-26T10:40:36.451-07:002011-08-26T10:40:36.451-07:00CNC waterjet cuts glass easily like butter.
