Here Goes Nothing...

The good thing about the 1/2"x10 5 start rod is that it doesn't need filing. Its just like the 1/2"x10 1 start rod in terms of diameter. I might make something out of HDPE and use that intead of an actual bearing. I can then make the hole a tad larger than 1/2" to fit the rod. Bob

Yes i had the same problem, thats why i made mine out of Delrin so it would last a while.

where did you get your 1/2"-10 five start?

Same place I got the other one. MSC. It was something like $70 for a 6 foot rod. I am using dumpsterCNC's anti-backlash nuts on it too. I should be able to get it installed tonight when I get home from work. I got the pipes installed yesterday and everything seems to line up nicely so far.

Can you share your files for the anti-whipping blocks? It would save me some time.

Thanks,

Here is a simple one i made. Stock is 0.50"

the v-carve, DXF and tap files zipped.

Even if you do now own V-Carve pro you can view it with the trial version i believe.

Thanks Joe!

I got the X axis working last night... what a BIG DIFFERENCE the new leadscrew makes. I am getting 250+ IPM rapids and its so smooth and quiet! There is absolutely no whipping in the X axis. It was definatly worth the effort.

I am going to finish putting together the bed tonight and start cutting some test cuts.

Here are pictures of the completed machine. I added 2 pieces of birch plywood on top of the top deck sides to prevent dust from getting on the rails of the X axis. The reason I choose the plywood was because I am going to screw down T-Tracks and the MDF doesn't take screws too well.

Next up is the electronics. I already have the drivers and power supply working from my previous machine but I wanted to put it all neatly in cases. I will post pictures of that this weekend.

Great to see you back on the scene Bob.

Quite a transformation from the 1st machine. Paint job looks great !

Looking forward to seeing it in action.

Cheers

Thanks!

Yes this is a BIG improvement from before. I finally got a house with a garage so I have the room for the larger machine.

Working on the electronics today..will post pictures of that setup soon.
