Thanks. I'll give it a try.

I have a PS05-5 power supply (5v regulated) inside my CNC control box that requires a FG. Can I use the terminal ground off of the incoming main 120V. See attached photo. Can I use the red...

Bad idea. You want to screw them on in case you need to adjust them later. Over the course of 2 years I had to make minor adjustments to my bolted down linear rails.

Mach 4-Hobby which is the replacement for Mach3 is out now. $200

Since the power is not 100 clean you may get spikes and do damage to the steppers. I would go with the 56. Also, since youre already ordering from PMD just get their power rectifier and add your...

I realize they are simple to make, that's why I don't want to waste my time making over 100 of them.

I am building a mini CNC router and my rails require 6-32 screws. 8020 does not sell 6-32 T-nuts. Does anyone know where I can purchase some?

Thanks. I have not fully found a solution, but I am still working it. I converted back to the PC that I knew worked. Your build looks great (I have not read it all, but what I have in the past 10...

I have attempted to use a Shuttle (us.shuttle.com) all-in-one PC (X50V2 Plus) with parallel port several times to no avail. Each time I tried my motors lost steps resulting in a very bad situation. ...

Thanks. The second link sells Knotty pine. May be worth a shot.

Where can I get stain grade pine wood that is about 4' x 4' x 0.75" Do they exist.

I do not want to use plywood because I am cutting (V-Groove) pretty deep into the wood and I cannot...

Some engravers in Aspire may have a flat bottom as opposed to the V-bit which will have a sharp pointed bottom. If youre Amana bit has a flat bottom, use the engraver tool bit in Aspire. If it is a...

Here's yet another build log of a G0643. I will try incorporate a lot of lessons learned from many of you who have done this before, but my main reason for having this build log is because I will...

It's been a year and I hven't posted any updates because I have been busy cutting and routing things with the machine. IT IS A BEAST! Here's one example of something I cut for a friend.

Another common name is drop-in t-nuts. I bought them for the exact same reason you quoted and they have sufficient holding ability. The little rubber piece is for you to grab abd hold while you...

I think I had a glitch in my program. Today I started it up and I cannot reproduce the same error. Thanks anyway.

OK, this has me confused. I imported the attached file into CUT3D and set my zero (x, y @ 0,0). I set my material size at x, y to be 6, 12" respectively. The z, thickness is 0.75" I went through...

Senna: I did the same search before I posted my request and came up with the same thing. Not the thread I am looking for. No big deal, I think I saved the link at my work computer. I just don't...

A few weeks ago I seen a very long thread on here with a dust shoe description and a few pictures. Does anyone know what happened to it? It was a really nice dust shoe.

It's been a week and I haven't gotten anything done because I was out of town. So now, back at it. I finally changed the Z-axis and used the new piece of 80/20 I procured to make my Z-travel...

Toolman: There have been many of these machines built based on the Ahren 80/20 design using 3.0" aluminum for the upper gantry. I used 6.0" (which I think is overkill) and there is absolutely no...

Well on day 10 I did get my router (Porter Cable) hooked up with a nice mount from K2-CNC. As far as I am concerned, I built a router in 2 weeks (same as 10 working days....well I am close anyway). ...

OK. I said I wasn't going to mess around with this machine until I procured my new 80/20 for the Z-axis to make it greater than 4" of travel.....well I was bored and wanted to see something move. I...

Kolias:

At your greatest length of 36", I don't see how you will have much wobble, unless you do a really poor job. I did mine free-hand with a table grinder.




Gerry:

I looked at...

Kolias:

Buy the screw and cut it to length yourself (if you have the tools or you can borrow them from a friend). A cut-off wheel will do the job in seconds. You can also grind the end to fit...

Day 7 & 8 have been the most frustrating. Day 7 I managed to get 'er all hooked up and tried moving the X-axis, only to find out the breakout board has separate power (not the DC) that I hadn't...

Problem Solved. Did not hook up AC power into breakout board. Only had DC in to power the Geckos. She MOVES!

My last attempt I closed the E-stop circuit and still no motor movement. Mach did reset and E-stop activate re-engages a few seconds later. Going to take a few screenshots of Mach GUI and will post...

I know this is the most common question, but here goes. I just hooked up a PMDX-135 motherboard with Gecko 203V's. Followed the Mach tutorials and no luck. Motor holds torque upon powering up, but...

I'm quoting this as day 6, but it's more like 6.5 with daylight savings time. But whose counting! I lost a bet that I would have the X and Y controlled by the computer by day 6. Cost me lunch and...
