Anyone know what's up with Hoss's main site? G0704.com is up (although it's prefixed with "migration"), and BF20.com is up for sale.

When I first looked at hossmachine.net it came up as expired....

Wow.

Oh no! Not Hoss too!! (Referring to the incorrect units of torque that nobody on the interwebs seems to get right these days.)

Thanks for the link.

Ray,

Can you tell us where you found reasonable gearboxes?

It's not impossible if you build your own PC!
I just bought an ECS 945GCD-M for that very reason. Now it doesn't have a fancy processor ("just" an Intel Dual-core Atom @ 1.6 GHz), but Mach3 doesn't...

Found this on toolmonger.com:

I work at a family-owned & -run business. Never again.

I just bought this one from CNC4PC: cnc4pc BX2

Nice size (they have a smaller one too), and it looks like I can fit everything in it except for the PC power supply (which was on sale when I bought...

I'm trying to find the thread that mentioned using that circuit for steppers too. It's either on this forum or the Benchtop forum. I thought it was Mariss who made the reference, but I could be wrong...

I'm probably making things much more difficult than they need to be, but I gotta ask!

The G540 has a built-in E-Stop input, but on the Gecko Support page there is a document that also accomplishes...

Is there anything more frustrating than the tramming process? (At least for the first time!)

I got it close but I'd like to do better. I'm off a couple thou in X and almost twice that in Y. While...

I was at the HF store in Saddle Brook, NJ today. While I was waiting in line I overheard the cashier helping the guy in front of me. She was telling him that the coupons you find in magazines and...

Went to my closest HF store today (Saddle Brook, NJ) to buy the 4x6 band saw. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93762
Imagine my surprise when I found it marked down...

I'm in the EXACT same boat, just farther along. I just finished milling all of the Hoss parts and drilling the holes for the Z column stepper mount. Next is aligning the spindle to the column, and...

Someone my wife works with asked if I could mill titanium on my X2. I immediately assumed it couldn't and told my wife to tell him that, but I really don't have enough experience to know.

What do...

I ordered and received these couplers from McMaster-Carr: http://www.mcmaster.com/#6208k6/=55n5jo

Very nice and inexpensive ($24.93 ea). Rated at 42 in-lbs, peak torque.

The label on the...

I had my eye on this one for a while: http://www.injectionmolder.net/

Less than $1500. It'll handle polyethylene, polypropylene, and polystyrene. Don't know what material would work best for...

It's time I started looking for some couplers. Anyone have a good source?

Do I need to pay attention to coupler torque specs, or are these steppers (<400 in-oz) too small to worry about this?
...

Thanks! That's what I was looking for!

ps In the interest of science, I'll measure deflections before & after the mod and post them here.

I'm going to do this: http://www.cnczone.com/forums/showpost.php?p=685391&postcount=21.

Do I need to have the back of the channel surfaced to a certain flatness?

Or can I use it as-is?

I got...

Torque is in units of oz-in, not oz/in.

I did use a center drill. Checked it again just now and it looks like it's off < .015 in the X axis. Y looks okay.

I definitely need to tune it up. I thought I'd do that while I was installing...

@MrWild: Forgot to mention that this is manual milling. I'm actually milling the parts to convert it to CNC (X2).

@DareBee: Closer to .005.

So do I assume it's my (newbie) technique or end...

Here's the scenario:
- Milled out a hole. Want to make it larger, so I thought I'd use the boring head for practice (but also because I don't have a jobber drill bit in the size I need).
- Removed...

I've got the 2" boring head (from LMS). I cranked down on the locking set screw (middle one) too hard and cracked what I thought was one of the two steel balls in between the screw & gib. As a quick...

I second that notion, although I've probably got more time in because I've never run a mill before and I'm spending a lot of time redoing setups to improve them!

Can't go wrong with Hoss's kit,...

Downloaded the trial version and have been trying to play with it.

"Trying" is the operative word because I find this user interface very non-intuitive and different from most other mechanical CAD...

Good catch! They have it for $69.95 if you're a student!

I'm downloading the trial version to see how it handles.

For a limited time, you can buy Alibre Design Standard for $99. Normally goes for $999. From the offer page:
You own it, permanently, and can use it for whatever you want. This is not a watered-down...

Ditto.

Thanks for the link Jeff.

I'm confused: shouldn't I widen the holes in the blocks instead of turning down the studs? The studs thread fine in the block. They just don't pass through the...
