Bj, thanks for the quote and pics. I still haven't made a decision on the clamps. I'd hate to see the alum I bought go to waste. I may try to cut it myself, but if I end up scrapping the parts, I'll shoot you another message.
Is anyone running Mach 3 off of their laptop? If I add a parallel port to my laptop, will I have issues running the machine? I heard something about the powersave feature in laptops messing with the timing? I'm debating if I want to build a cheap computer into the left side of the base. That would be pretty cool and there would be less wires running around.
I currently have that, but there was a thread somewhere what you have to do to make run as Desktop. Turn off all the power savings features. Otherwise its runs fine..
If you left yourself extra bays on the left like I did, you can, but you are limited to something like a micro-atx Atom motherboard. Adequate, though. The Intel 525 (I think) apparently does well and has a parallel port. The slick thing would be an atom board with a pico power supply and a SSD. I figure a minimum of $250 + software. I have no idea if it runs Ubuntu, which is what I'm doing. Me: 6 year old AMD celeron 1.8 ghz I salvaged. Free. Free software too.Originally Posted by GTFreeFlyer
Nice. You mean something like this? Can I use a USB stick as a hard drive? I've never tried that before. That would be more ideal that buying a SSD or other hard drive.
I have a Intel D525MW mb running Ubuntu 10.04 with EMC2. The SSD boots up fast and quiet.

GT, yes, like that, but you can't fit the case. I was thinking bare board. I'm not sure the differences between the 425 and 525, but several say the 525 works well. Most microatx don't have parallel ports, so make sure to check for that.
I've read that generally usb type memory doesn't last very long as a HDD. I do know of an application where they use compact flash and do fine though.
The Intel 510 is 1.6gHz and has a 26pin header for the parallel port while the 525 is 1.8gHz and has a DB-25 for the parallel port. There are some bugs in the 510 bios that are fixed in the 525 bios (I don't believe they released a fixed bios for the 510).
Thanks for that. I was looking for the speed of the 525 and its not easy to find on Intel's website. I'm currently using a 1.8ghz AMD Semperon. I'm thinking it would be similar.
Clamps are done. I'm glad that's over with. They seem to hold the Colt with authority. We'll have to see how they hold up to the vibration when I start cutting parts. I designed them to all fit in the 3x10x3/4" alum block I had purchased (per the plans). They were very easy to make, just quite time consuming to cut with a hack saw. I used a 2-3/4" and 1-11/16" bi-metal hole saw on the parts, which mate nicely with the Colt.
I had already made the z-rail and block (parts 25 and 26) per the plans before I knew I was going to buy the colt, but I lucked out and was able to just drill new holes in them to accommodate the Colt. I don't need any extra parts to hold the Colt other than the new clamps and mods to parts 25 and 26.
I bought a counterbore drill for the 1/4" SHCS and that really adds a nice touch to the parts.
Looks like I'm going to have to remake part 28 (nut plate) since the anti-backlash nut flange has a different hole pattern than what I drilled into the nut plate. Does anyone have some extra aluminum for this small part they wouldn't mind sending over?
Assembly is starting to take place finally!
I got my rails from Online Metals and the stock was bowed. How was yours and where did you buy it?
I guess I haven't really looked at it closely for straightness yet. Just from holding it and placing it under the drill press I haven't noticed any bowing, but I'll have to wait until I place it in between the bearings to see how straight it really is. I got all my metal from speedymetals, except for the rectangular gantry tube which I got from onlinemetals.
