I now have this machine up an running. My cutting area is 23x38. Sorry I do not have a total set of plans made, I only have TuboCad Designer and it does not do 3d to model the machine. I never weighed the gantry but would say 60lbs would be close. I use a HobbyCNC card with the 200oz motors, 24v power supply, and 5/8" 6tpi acme screw. I can get rapids up to 120ipm but this is very close stalling out. I generally rapid at 100ipm and cut at 60ipm. I have cut at 80-90 ipm but start to get some chatter from the router so I leave it at 60 and it cuts great. The carriage for the z axis is what causes the chatter as it will flex at those speeds. I need to figure out how to eliminate that flex and will be much better. Although with the motors pretty much at max speed now I really don't know if I will mess with it. 60ipm cut speed is just fine with me. Some of what I have cut with it so far can be seen on the PhotoVcarve forum. |
