K2 is out of business. Here's a company that can probably help you get going: CNCRepair - Home

The K2 3925 has zero backlash ballscrews.

Mine's a 3925...don't know the screw pitch details. Rapid is about 115.

Very nice...but for Heavy Metal I would use brass.

Sounds like a very cool project. Keep us posted on your progress.

Why not try out your techniques on some copper water pipe even though the ID and OD won't be exactly right. You can still practice raising toneholes, mounting posts and keys, etc. Are you going to...

Have you checked to verify that your pulleys aren't slipping?

I assume you are referring to the 3925? Give K2 a call. They have always been willing to help me on the phone with any problem. You won't find much help on this forum...no one here. Good luck.

You'll find nice table plate near the bottom of:

It would also be nice if standard 1/4 x 20 bolt heads would fit in the T slots.

What the @$#&! Are you talking about the little bump on the way down, or the screaming all the way up! Are the guide rods greased? I'd send the link to K2 and ask them what needs to be done to fix...

Is there a command to make the machine ignore all Z values starting at a certain place in a 3d file? I want the Z to stay at the last specified value without having to go through and manually remove...

Is there a way to make Mach 3 ignore all Z values starting at a certain place in a 3d file? I want the Z to stay at the last specified value without having to go through and manually remove all the...

Check out the section on Woodworking Machines and then visit their websites. I have a K2CNC 39x25 which has been satisfactory and a decent deal for the money. Camaster makes a heavier duty machine...

C'mon...there are few enough interesting posts on this forum as it is. Why keep it private? Put it out there so others can read, learn, and possibly contribute. That's the purpose of the forum in the...

Is anyone using the relay that K2 sells? Please explain how it works. I want to use it to control the router and dust collector. The router is 12A and the DC is 12A. Will this work? Do you have to...

The manufacturer has sent me some new home switches, but I just haven't put them on yet. I've heard other people say not to depend on the home switches, so I thought they probably wouldn't do any...

Yes, please tell us how to do this. I can't depend on the the home switch always putting zero in the same place; it usually varies by .010 to 030". Consequently, I have been zeroing the x and y...

Yes it's possible. I'm using mach 3 and at the end of each file, I send the x axis home which causes the gantry to activate a mechanical rocker switch that turns off the router and dust collector. It...

I have a 3925 and have been very happy with it. However, I'd probably trade it in a minute for a Camaster Stinger II (not stinger I). The camaster is a much stouter machine.

That blob in the corner might be your model. Try using the mouse scroll wheel to zoom in on it. Use the right mouse button to drag it to center. If you think a line of code is interfering with the...

Check out CNC g-code editor It's a very useful program for altering g-code. For viewing your toolpath in Mach 3, you just click on the "Toolpath" tab on the mach screen. That should show you a...

I got my KG-3925 four years ago. It is my first CNC router. I do heavy routing in extremely dense rosewoods. Almost all my work is 3d and routed on both sides. I haven't had many issues with this...
