Hi all, I am new to openbuilds and to the CNC world. Now that the V-slot is getting back in stock I'm getting excited to start a project of my own. I have done some reading and have come up with a idea of what I would like to build. But before I go out and spend my hard earned money I would like get the thumbs up from you guys, who have more knowledge and experience. The general idea is that I would have an OX design but bigger (1500mmx1000mm), with the possibility to change the spindle with a printing head for 3D printing. To get more Z height I was thinking to increase the rail length on the Z axis for about 250mm. When 3D printing I would raise the whole machine and with the longer Z axis I would have cca 300mm printing depth. When milling the Z hight would be the same as in the original OX. A guide of 3D printing with mach3 is found here: http://www.shapeoko.com/wiki/index.php/3D_Printing_Mach3 Regarding the spindle it would be a brushless motor similar to the one from Robert Hummel, but with a few changes: Motor http://www.ebay.com/itm/141174603725?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 ESC http://www.ebay.com/itm/200597198227?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Power supply: 2x connected in series to get 24v 55A http://www.ebay.com/itm/150833352692?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Looking forward to your comments and critics.
