Great write up Silly. I've been thinking about doing blocks like that in addition to my back plate for a few months now. I never measured my deflection and I don't have a tenths indicator yet anyway,...

WOW, I'm always surprised at the vitriol directed at people who try to solve problems in ways not considered "proper" or "traditional". I came here so many years ago in search of quality info to...

It happens migrusch, no hurt feelings.

Let's get back to building machines, yes?

Wow, sorry to have wasted only my time and effort and no one else's. :confused:

The point for those that might have missed it was that with a spacer, the column would in fact be stiffer at the...

I'll second that. The part couldn't be much simpler to make. Looking forward to test results.

You bring up a good point Handlewanker, and I've been thinking about this all day now. (the joys of unemployment)

It's been a couple of years since machine design class, but the way I understand...

IMO adding the spacer won't hurt you compared to doing the same cut without a spacer. That's the important part. Taking a cut at the same distance from the table, the moment arm is identical,...

I ran 24V on my x2 for a few months with a TB6560 based controller... Even with the stock acme screws it would run about 20ipm rapids no problem. You don't need super fast rapids on such a small...

I actually split the nuts lengthwise (parallel to the screw) contrary to how it's usually done here, because it seemed to make more sense. You don't lose any threads in the nut that way. However,...

The y axis block was by far the worst on my x2. I ended up machining the block and screw to accept a pair of sealed bearings, the difference was incredible. The second best improvement was slitting...

It's always nice to have a pile of new shiny parts to play with. :-) Good luck with the build.

I had a hard time finding a bearing with 12mm ID and small enough OD not to get in the way. What I ended up doing was ordering a pair of 10mm ID bearings from VXB Bearings on eBay and turning that...

I used belts on all 3 axes of my x2, for the most part it works great. My reasoning was space: I had an x2 and a mini lathe both enclosed in my hall closet, so every inch counted. The belts on x...

This is great info, thanks Lasik. I have a 4 axis board that looks identical to yours from Wantai Motor on Ebay. It's missing steps pretty regularly especially on the Y axis of my X2, I thought is...

I have one of those chinese 6560 boards running my x2. So far, it's been fine with 24VDC (2 modified computer PSUs in series) I wouldn't go any higher though. If you're handy with electronics, you...

I'm planning on doing a build thread once I get a little farther along, stay tuned.

Amishx64, how are you suggesting to disable ACPI? I might be able to give it a shot this weekend with one or more of my machines.

I'm building my x2 with a similar kit, purchased from Wantai Motor (wantmotor on ebay). It came with a 4 axis driver board and 4 270 oz motors, to my door for $250 CAD. Ultimate speed is not my...

I don't have a PP printer that I can test on, mine is USB/network only.

However, I can tell you that my driver/BOB is powered and optoisolated.
Not sure about decoupling caps, I can't see...

Well, you can put my 2 on the bad list so far. (satellite A75 and Tecra 9100) I also tried the drivertest program on both and saw the nasty, noisy signal. The steppers sometimes move smoothly, but...

Amishx64, I don't really intend to put much effort into the laptops. I found an extra wide desktop tower in the dumpster a couple weeks ago :) so I'll use that. I think I can fit the PC, drivers...

I've had no luck with laptops so far. Tried a Satellite A75 (P4 3.06) and a Tecra 9100 (P4 1.7) and neither gives me a smooth pulse. I can hear the steppers stuttering. No problem on my desktops...

I haven't got mine completely done yet, but I went for a super-compact layout with my x2. My machine shop is a 62" long coat closet, with the x2 and a 6x20ish lathe, so space is at a premium. IIRC,...
