Z-Axis mounted to X. Working on mounts for stepper motor and 1/2-10 acme drive.
Wow that looks fabulous. Merry Christmas.
These look fantastic Bruce. Any chance you can share a link to getting these beams?
@Dat_Chu the rails came from this ebay store: http://www.ebay.com/usr/econvenience1986?_trksid=p2047675.l2559
Then I mounted them in the aluminum.
hello, looks very well ! the screw have a anti backlash nut?
I have one of those silver faced digital calipers. The black faced ones are a little more money, but they are much better in my opinion. Man I hate my silver faced pair compared to the black one. I’m just saying.
@Eugenio_Villaverde I made HDPE lead nuts for my half by ten acme lead screws. HDPE is pretty elastic, so that eliminates backlash. Although the cost of acme taps is ridiculous. So I made my own out of a bit of extra threaded rod. I found that just cutting grooves wasn’t enough. I had to peen the back teeth of my homemade tap to spread them open a bit. Before I did that the nuts I made were way too tight on the rod.
@Eugenio_Villaverde e I am using an acme nut inserted into a piece of hdpe, and it seems the backlash is minimal.
@Paul_Frederick I agree the black face one is better! not sure of the brand, but happy with both.
@Bruce_Lunde
Yeah I only have one of each. So it could just be the luck of the draw I have witnessed. I have seen that with other far eastern products. It is often a crap shoot whether one is good, or not. I have a bunch of the Harbor Freight freebie multimeters now too. One works, the rest all do various different things. One seems absolutely spot on to me though. Just the law of high numbers coming into play there I’m sure.
What size of rails are you using?
Y is 1400mm, x is 880 mm, z is 380mm
What diameter
@Robert_Altman 12mm, although if i did it over, I would likely use 20mm for the Y axis.
@Bruce_Lunde that’s my position right now I’m trying to plan out to make one but I’m thinking about making it smaller and more rigid I would like to cut harder metals like stainless steel. I like to go to box ways but they may not be in my budget. I’m the machinist and I know they need to be super rigid. Looks like the round rails have a five degree tolerance on them.
Wow. Your machine is much bigger than most. And they are all solid too. What is your plan with this machine @Bruce_Lunde ? Just milling aluminum?
@Dat_Chu I expect to do wood and aluminum; several projects will benefit from this being built!
