Hey I read what you said about the antibacklash nuts and the countersunk holes. Nice work milling the standoffs down on the end but I want to warn you that if you're using a design that didn't account for the countersunk hole, you may have alignment issues with your leadscrews. While assembling my Sphinx I noticed the same thing but kyo's build manual didn't call for any modification. If anything, you may have to add a couple washers under the standoffs. I ended up 3d printing small rings to basically just fill those countersunk holes in the delrin nut blocks.

 

So I ended up using these db9 connectors for the stepper motor cables instead of using the aviation connectors most people use. I did this because I found these dual db9 breakout boards that take up those pci slots. It worked out really well because I didn't have to modify the case. I'll send you links when I get home.

Which 5v are you talking about? My controller doesn't require a breakout board if that's what you're asking.

 

Are you using a mach 3 controller?

 

If you need 5v and you're using a host PC like me, tapping into a spare 5v line is no problem as long as all your components share a common ground.

 

My setup is basically an Arduino uno based CNC controller embedded in the host PC.

 

So I ended up receiving two computers from someone that was getting rid of them. One was a small dell with an older i7 920 and the other was a really old gaming PC with a large steel case. I ended up removing the junk out of the gaming pc and installed all the smaller hardware from the dell so there was plenty of room. I'm still not completely satisfied with it but it works for now.

 

That is brilliant. I wish I would have thought of that.
