Hey Nathan,

Tried calling you but the number you provided does not seem correct.

I'm interested in buying this.

Thanks!

Hi,

I think I'll pass on this. $243 for freight is too much for me.

Thanks!

Any idea on how much it will cost to ship to Apple Valley, MN?

Do you still have this for sale?

The specs of the controller you're using should say what microstepping you have.

Looks good! Too bad the spindle drops with power off. So do you have everything up and running (like automatic returning on/off of everything)? :-)

You'll need more info to calculate steps per....

Amazing. I've always thought about building this MQL but have never gotten around to it. Now I've got somebody who can show me how. :-)

It's even more amazing that I just received a notification...

Hope it works. Looks like one labyrinth of sound amplification to me. :-)

Sound waves will be bouncing all over those melamine boards.

Oh, and seal all the other openings with acoustic sealant.

If you're at 100db, you need to reduce the noise by at least 20db. You ear can handle a constant 80db.

I was able to reduce the noise of my pump from 90db to 70db (and down to 0 db once the motor...

The noise on my vacuum pumps are coming mostly from the pump itself and a little from the motor. Do these mufflers mount on the pump? Can you point to a source please?

Make sure you have enough ventilation. I put my vacuum...

You should be able to set them in mach3 in the ports and pins section. Set them to active high. Or is it active low? Anyway, set it to opposite of what it's set to in mach3 in your current setup. :-)

Very cool!

What cylinder did you get, meaning how much force is it exerting?

I was wondering if the shoe will be able to ride hills and valleys if you're doing carving? I was t thinking that a...

Amazing! One of these days, you'll have to show me how you made the parts.

Too bad my mill is not working right now. It would have made short work of your plates.

0.1".

How did you setup your z-axis in mach3 without knowing the pitch?

Interesting. Care to elaborate on what you're seeing with Mach4 that you do not like? What other alternatives are you considering?

Turn the spindle on for a given amount of time and then turn it off.

BTW, are you working on a Mach4 screen? :-)

Would like to get that too, please.

Since we're already asking, is it also possible to have it timed? :-)

Your plate will probably be connected to the z-axis on one end and the spindle on the other end. If that's the case, you might get a lot of flexing if you use a 1/2" plate (especially if it's 17"...

Damn awesome job! I'd like to talk to you sometime about how you did the monitor mounts using the 80/20 and the stepper drivers. I always thought that it was normal for steppers to get very hot.

Cool! Yeah, that manual/electronic feature of the VFD got me going in circles too when I was setting mine up.

Out of curiosity, how did you end up wiring it?

I'm still not getting a...

BTW, I'm giving a presentation on "Building a CNC" at the local CNC club this weekend. I've been stealing, I mean borrowing, some of your pictures as examples. Hope you don't mind. :-)

Also, make sure that the relay switch on your BOB is closing when you issue an M3.

Check if you're pulling your M1 to VFD ground when you issue an M3. If is not, there's something wrong with your wiring. :-)

If it is, is there a setting in the VFD that turns it from being...

No, one of the two spindle connections should be connected to the M1 (or should it be M0?) in your VFD and the other spindle connection should be connected to the VFD GND. There does not be a...

GND to ACM on the VFD
The relay (top screw connection on BOB) connected to M1 on the VFD.

Looking at the BOB, there are 2 connectors for the spindle. Right below those 2 is GND. Is that GND...

Ah! Didn't know you're using the smoothstepper. Here's the spindle setup docs. It took me forever to find this.

I'd like that G540 back. Another friend of mine can use it. :-)

I didn't have to setup the spindle in the Motor Tuning and Setup window for the G540 but did have to do it with my Smoothstepper....
