Peter, thanks for the kind words. It's good to know someone is enjoying the posts! Also good call on putting some bumpers on the Y-stops. I read you comment and thought "hmmm why not?" Then looked down and saw my box of tubing scraps. Turns out some 1/2"x5/8" clear vinyl tubing is a perfect fit! 5 minutes later and now when the carriages smack the y-stops they don't make such an impact. =)
Initially I was just happy to not have the y-axis falling off the rails while I tinkered with it.
Cd_edwards: Thanks! I get as much joy from inventing as I do hearing other folks appreciate it. One word of advise if you're going the route of buying a few parts here and there like I did: have a really solid plan! I've said it before but I reallllllllllly wish CNCRP had their kits available when I started. This would have saved me 100's of hours of work and planning it in my head only to realize that I didn't take everything into account. Then again, I'm stubborn and addicted to DIY so there's a fair chance I wouldn't have bought the kit even if I could.
For example one major flaw I found in my 'design' is that after all the work to make a true 4x8' machine (work envelope) I am going to end up with a roughly 45"x90" work area. This I could have avoided if I had planned a bit more on paper vs in my head. That and not jumping on a 'sweet deal' for the 3060 gantry. 49" seemed like it would be enough when I purchased it over a year ago... Bummer but the beauty of these modular 8020 extrusion based machines is that I can eventually upgrade just the parts that need to be upgraded over time.
If you are building a machine like mine feel free to post questions here. I've learned a ton building mine and would be happy to share things I've found but forgot to post in the build log.
-Extending the 220v line I found in the rafters to the machine console where the VFD will be mounted.
-Need to bite the bullet and order a 2.2KW Chinese spindle so I know what size of tubing I'll need for water cooling.
-Obtain some shielded cable for spindle
-Obtain some 4" dust collection hoses and assorted bits
