6mm BallScrew In Service (pic)
http://www.yumabassman.com/pictures/...20Axis%20b.JPG
Well, there it is. It's a combination of design to fit and machine to fit techniques, but it screams up and down at 40 IPM. (Fastest I can run without changing the kernel speed.) I expected to be able to stall it very easily with the stepper running that fast, but I was unable to stall it by bracing my hand against the table and bushing upward with the axis rapiding downwards. (I think the G450 must switch from micro steps to full steps over as certain step rate. I'll have to ask Marcus about that.) Now I probably need to map the screw. Repeatability is very good, but accuracy is pretty bad at different distances along the screw. I never had to map a screw before. Funny that the first ball screw I install has the worst accuracy of any screw I've used. LOL. |
