This is my ninth CNC project. Started thinking about building a large format table three years ago. It’s status has moved up and down my priority queue many times - I’m finally ready to begin...

I had the same thoughts. Looks like it could turn into a House of Cards.

Thanks for all of the comments so far. Nothing there that would impact me.

I did find this video. Unfortunately I was preoccupied with how cheaply the megabuck Shopbot was constructed as...

This isn’t a build log. I’m posting in this forum because it appears that this is where the brain trust for larger machines resides.

I’ve built a number of smaller format machines and started...

Are you willing to disclose the estimated cost of your finished machine?

BTW: No fuses are visible in your photo of the electronics cabinet. Did you install any?

The belly button looks great, but the nips still need a little work.

Seriously, Went through your thread for the first time today. Fantastic machine with incredible precision. I'm amazed at the...

At what time do they meet on the second Thursday?

This is without a doubt the most professional build I've seen here.

Have you computed the overall weight of the gantry? It appears to be heavy.

I know nothing about R&P motion systems, but...

I wanted to build a couple of resonator guitars with a goal of making them as close as possible to solid body electrics. The first picture is a comparison with a Les Paul. The first one is a Dobro...

Brian,

Thanks for the compliments, but I'm sure there are many people who are making incredible things with their machines.

BTW - "Pimped Up" doesn't have a pornographic inference. It's just a...

I did something similar to your original question designing a single control box that could be moved to multiple specialized machines. The box has switched 120V outputs to control the spindle and a...

1. Wiring from the parallel port to your G201s should be isolated from any 120V wiring and the wires that go to the motors. If they're too close, noise can be induced into the step/dir wires with...

Check out this puzzle.

Hey Bird Man

The end product looks very professional - Congrats

BTW I probably live only a few miles from you. Have 7 woodworking machines running GREX controllers. Let me know if you would...

I live about 20 miles from Boulder. Can offer a limited amount of help.

Bob's website boasts about their long list of prominent customers. Included in this list is NASA.

I'm wondering if this rocket was designed using Bobcad.

Hey Don,

Haven't seen you around here much recently. Hopefully the Gee-Tar business is doing well.

I'm curious as to what their marketing angle was - Increased functionality? Bug fixes? ...

I thought that was the answer - just looking to have one less assembly to build.

The laser will be mounted on a fixed horizontal gantry and a stepper controlled linear actuator that will provide 7...

I'm getting close to starting in the construction of a machine. The workpiece will sit horizontal on a moving X-Y table under a 50W Chinese CO2 laser tube pointing straight down at the work - no...

I Posted my Wireless Pendant thread in the Open Source Machine section before realizing that it was probably more appropriate here. If interested, the thread is here:
...

You're whining and crying here without providing us with any additional information to help diagnose the problem.

$75 is outrageous for a simple license transfer. They will key your account to...

The axis definition comes from the Cartesian coordinate system. Wiki does a good job of explaining it here:

My dongle wasn't working and Viagra fixed me right up.

Seriously, I had a similar problem and discovered that you must be running in Administrator mode on your computer for it to see the dongle.

Good point. Didn't think about this until you brought it up since I was only interested in momentary operation.

If you compare my photos with theirs it is apparent that they're shipping a newer...

The wiring is simple. This device provides NO and NC contacts from the 12 relays. I wired one side of the NO contacts to ground and the other to the corresponding input on the GREX. When a button...

I saw this 12 channel remote control setup at www.lightobject.com and got the idea to build a wireless pendant. The cost is only about 28 Bucks so it was a low risk venture.

This can be added to...

I’m still in the design phase of building a laser machine. Decided to throw out a few questions here before I go down the wrong path.

Here’s what I have:

50W Chinese CO2 Laser tube

Received an email from Bob today announcing V23 and Bobart V23 which has V Carve capabilities.

Called Bob to find out if the new Art program would work with V22 software as an upgrade to my V22...

Go to Ebay and check out item # 130255753087. This seller has a number of these lots available. I purchased many of these and they work great on most hardwoods.

You didn't state what you want to use Bobart for. I suggest you take a look at BMP2CNC for similar functionality to the 3-D portion of Bobart. Cost is only 36 Euros. You can download a fully...
