What are you using for the control?

- Basic Mach3 package with a Gecko 540 driving a 1200oz Nema 34 Z axis and 540oz Nema 24 X and Y.
- I re-tasked an old Dell Optiplex 980 with an i7 and 19" touch screen for the interface.
- The spindle is a 1.5HP 3ph motor driven with a Teco 2HP drive. It has the belt drive kit so top speed is just over 7500 RPM.
- I've redone the limit switches 3 different times now and finally installed decent prox switches with quick connect cables.

I've been doing Industrial controls/Instrumentation and automation for 30+ years now in many industries but started this project while I was working for a German Automation company who builds robotic riveting machines for Aerospace. This is child's play in comparison but it helped me learn the job at a depth that set me above everyone else.

My Heavy Metal double ball screw kit arrived today and the fit and finish is so much better than my original kit.

I didn’t pop for the precision bearing upgrade.

I started swapping Z axis parts yesterday but the lube lines I installed made it a much more complicated process. Nothing major but a bunch of tedious changes to ensure clearances.

Such a clean kit, I only wish this option was available when I did my first conversion.

Tackled the X and Y axis today. I got the Y done easy enough including the lube line but now I have to figure out how to machine in the slot required to clear the dual ballnuts without a milling machine.

I bought a Milwaukee finger sander a few months back for a special project and it came in very handy today for clearancing the Y axis ballnuts so I’m guessing that I’ll handle the X axis with an angle grinder and then clean it up with the finger sander.

Very nice. Do you know the accuracy spec and backlash spec on those screws? I've been running Roton brand ballscrews for 8 years now in my G0704 and don't have many good things to say about them - they're not really made for precision CNC applications. I'm probably going to scrape the entire machine this year and will probably replace the screws with something better in the process.

This is my first post that I can remember making. I'm usually more of a reader. I wanted to say Nice Shop! You're very organized and by the looks of things, out of room. I'm in the same boat, out of room for even a bookshelf I'd like to add.

Yes, I am all out of room, even with the extra bay on the garage.
I'd love to start selling off some things but I actually use all of it.

The Jetski's take up the most room and get used the least but there's no way I'll ever sell them.

You have a lot of vertical space you could utilize. Looks good!

Vertical space is good for storage, which I have a ton of up in the attic. What I need is more floor space!
I am collecting the parts to build a CNC plasma table but I have zero floor space to ever set one up.

Here's some "creative" storage space I integrated into my work bench. :cool:
