C1 - Would you mind posting a link to Gerry's site so that all of us can get his screenset?

Sweet! I love seeing the big machines come together.

Would mind elaborating on why you chose to make the gantry across the long axis?

Also, if any racking-or moving out of square occurs on the axis, dual motors will let you individually home the motors to true-up the axis.

Free plywood you say? Now I see why you finally started your build ;).

You know, I thought when doing the research for my build that I had accounted for everything that I would need in my CNC...

I used all CNCRouterParts for my 10×2 build. I know, odd size but it was what fit the room.

My machine is capable of 2500+ ipm rapids... So fast it is way too scary for me. Just so I can keep my...

See this photo. I don't have the grounds joined AT the G540, but I do have them joined at the ground connection on the DC side of the G540's power supply. I believe that this is the same thing... but...

So I am still having no luck with getting these switches to work with my g540.

Here are the facts as I have them.

The g540 uses parallel port power and ground for its input ports. The Parallel...

I know that this subject has been discussed to death in this thread... And I have re-read the entire thread multiple times. Quite simply, I cannot get Mach3 to respond to any of my switches.

I can...

For my 2nd generation switches, I am weighing these options...

Are you looking at achieving something like this?

From my experience cutting Carbon Fiber, we always ended up using air tools. Full face respirator and an air cutoff tool all done outside. Caron Fiber itches like a mother if you get any length...

Yea, but think about the insulated heaven in which you will be able to partake in said recovering...

For my R&P, I have the Acceleration set at 40 and have had the velocity as high as 2400 ipm. I'm thinking that I will slow it down to 1500ipm or so, but the capability is there. As I have come to...

I'm not sure if 8020 themselves actually have a piece of hardware specifically made to do this, but I'll do my best to describe what I did.

First of all, you have to drill access holes through the...

You can use all 4 holes on the inner sets of bearings, so gusset(s) there would work. However, the outer bearings that carry the R&P can only be attached with the inner holes.

I have been...

Well I went to get my other axes up and running today and I found out that my X-Axis controller on my G540 is not working. I had a look at the trim pot screw and it looks stripped... I guess that it...

Yea, the video is a bit misleading as far as the sound is concerned. I don't yet have any sound absorbing material on the walls, so a lot of the sound reverberates in the room.

The motors are on...

I really was laughing out loud. I used the driver speed tester program to see what kernel rate I could run my computer at and it said I had no problems at 100 khz. I currently have Mach3 set at 65k,...

When I had finished drilling and tapping every hole that I needed to in the frame, I completed its assembly. I used corner brackets placed underneath the frame to keep the supports in the proper...

Hehehe. I did use the numbers provided by Ahren at CNCrouterparts. I haven't done any tuning of any sort to the machine, so I don't really feel comfortable showing it off quite yet (plus, you...

Quick post / Spoiler alert ... 2000ipm rapids ... :D

Lots of catching up to do. Lets see, I believe that I left off with the completion of the cabinet that the CNC machine will rest on.

The first step in the construction of my machine was to cut the...

The design is coming along. I'll try to help with whatever I can.

1. One thing to remember that can be difficult to see is that when using the R&P fixture on a carriage, you cannot use the two...

I don't think that it was quite finished on the DC side of their enclosure. There were some wires that were hanging loose, not terminated.

When you mount your viper drivers, be sure to mount them to a hefty piece of metal. It looks like they use the case that they are mounted to as a heat sink, so the larger the piece of metal they are...

I would fill the tubes with play sand or concrete

This photo always makes me laugh.

But, it does give me an idea on where to put my CNC in my dorm room. Hang the thing from the ceiling! Psh, screw my 187 ft of floor space, I also have 187 ft of...

I don't really know, so take everything I am about to say with a grain of salt.

I believe that most or all solid-state relays fail ON. This would be a very bad thing if they are wired in to the...

I would try jogging at a few rates. ie 10, 50, 100, 250, 500...

Hopefully one of the speeds will provide you with consistent results that you could then analyze.
