You have a hammer with a built-in bottle opener? Want!

Personally, I'd just post process cleaning up the holes with a reamer. It's much more precise anyway.

It strikes me that that wooden ball screw would make a magnificent lifting mechanism for a "Rolling Ball Sculpture" (AKA Marble Coaster, Do Nothing Machine, etc.)

Interesting. A lot of what I know about motors is based on PMDC motors, but the more I learn about steppers, the more wildly different these animals appear to be.

So these drivers know to run...

Exactly. Inductance is a sort of resistance caused by the magnetic field in the motor "pushing back" against the current flowing through the windings. But at startup, the "Back EMF" hasn't formed...

So, the problem is "Inrush Current". Interesting.

It seems to me that if 2.25 A is normal and acceptable, if you could set the limit to 9A (not 10) that should serve the right balance between...

Remember, just because your power source can SUPPLY 175 Watts, doesn't mean that your load is going to DRAW all of it.

Well, Dualkit, you might want to look at Titanium Joe too. He specializes in drops and surplus, so you might get better prices. (Which explains his very weird price list).

When I was building BattleBots, this is where people would go. http://www.titaniumjoe.com/

At first, I was concerned this was a spam or something, but the link to the CNC routed house trim is quite cool. You might want to edit the top post a bit....

Ah, I wasn't sure about the networking, since I read in another thread about someone having timing issues related to a wireless network card. (Still, getting a cat-5 line down there would be more...

Egad, it's been a while. I haven't given up. But a mandatory overtime happy manager has really been eating up my summer.

"Step 0" is finally complete (Van is fixed and legal again) and I've just...

By the way, I haven't vanished. I just have to take care of "Step 0" of my plan, which is to get my van fixed up and legal again. Can't quite pick up sheets of Birch Ply in the Subaru. Annoyingly,...

That's very impressive! The figurine too. (What on earth has happened to my priorities??)

You must have a pretty high clearance between your table and the gantry for that, how much?

I would...

I see the Wi-Fi antennas. That might be a problem. I recall seeing in another thread that someone had issues with their wireless network card interrupt causing timing problems with their parallel...

I'm curious about where you get the numbers to decide that R&P is cheaper.

Instead of flanges, most of the drive parts stores have smooth pulleys with flanges on them which could be used for your...

No, you're making perfect sense.

In my earlier ideas, the top of the "Apron" was flat, and the Y-axis sat on top of it. Then I could level it to the table by shimming.

But then I had the idea...

One thing you might need to deal with is an ability to adjust the tension in the drive pulley in the middle of the tank tread depending on the "Timing" of the connection to the fixed belt, while...

While considering how to connect my gantry to what I'm calling the "Apron" (to steal the term from a Lathe to refer to the part containing the X-axis bearings), this thought occurred to me. Has...

Meet with Customers elsewhere.

Get yourself elected to the Council (or however that works).

Laminating two pieces of plywood together will not produce nearly as much rigidity as taking that second sheet and cutting it into strips and attaching them at right angles to the bottom of the...

Man, there's nothing like doing a Sketchup model to force you to think of the less "sexy" parts that you still need to take care of....

Got my tax refund. More than enough to fund this build.

Not quite true, that doesn't include the previous versions of .net, it just includes the service pack updates for them.

The worst thing about .Net is that the various numbers are NOT true "Version Numbers", in that higher numbers do not include or update the functionality of the "Older" versions. You can end up...

I think you've got both factors going. Heavier items will move more slowly, and take more energy to get them going at any amplitude, but the epoxy increases the rigidity, which increases the...

That's what I liked about the cable system, unlike the tables that run one leadscrew under the center, or running a shaft across underneath, the cables won't interfere with legs, which I'd like to...

Since one thing I was considering for the RouterBeast was the possibility of a lathe on the side, I wanted to keep the A channel available for that. I know that it doesn't work well to have two...

Wow, those are some great replies!

harryn: Hmm, I was thinking "Architectural" square tube for the LaserBeast gantry, with 20 mm rail on either bottom corner and the mirror/lens suspended directly...

Hmmm, I wasn't thinking in terms of 34's, really, but I guess for the plywood router that could be justifiable (maybe a 23 for the Z-axis). For the laser machine 23's are probably the better choice...

I have one of those cooking thermometers! (Only problem is the "Low temp" Min function has never worked).

Looks good! I bet you get extra cooling of that spindle from the airflow. You couldn't...
