This is a possibly stupid question, but the design that I'm looking at building is only a three-axis model. Can I run the G540 using only X, Y, and Z, and later build a new machine that incorporates the fourth axis?
I was able to find the Bosch Colt variable speed on eBay for about $120 shipped on eBay...not bad! Including that and the G540 package from Keling, it looks like my cost (after taxes and shipping) should be somewhere in the $1100 neighborhood. That's right on budget (my budget didn't include the tool purchase).
Another question -- with this tool and the G540 kit, is the limiting factor for cutting aluminum or other soft metals going to be the stability of MDF? In other words, is it feasible to take the electronics, steppers, and router that I have listed above and move them into a sturdier frame table down the line and be able to cut metal? My biggest concerns are the steppers and other assorted electronics (like the power supply) -- if they don't move to another CNC setup after my first, they'll collect dust or just be passed to a friend, whereas the router can certainly find more use.
Thanks so much for all the help you all have given so far...going on a cruise later this week and next Sunday is my birthday, so I'll finish up my decision making by then and take the plunge!  |
