Hello all,

I'm currently using a CNC that I built off the FLA-100 plans. For those unfamiliar, the FLA-100 is a 24x36" table top out of 8020 extrusion with flat steel ways and roller bearing...

I've been looking around for another coupler solution. What do you guys think about these Stepped beam couplers?

Axis moves smoothly, no binding no problem. I can turn the acme with 2 fingers to move it. That's not the issue. The assembly is motor->Helical Coupler->1/2" drill rod->Bearing block->ridgid...

Thanks for the reply, but I don't think you're understanding the issue- when the bearing block is attached to the motor through the helical coupler, but not attached to the acme screw through the...

Thanks for the replies everyone!

In the design, the assembly is motor->Helical Coupler->1/2" drill rod->Bearing block->ridgid coupler->acme screw->Z axis carriage. With the ridgid coupler...

The couplers are these:

I believe they're aluminum, actually, but could very well be wrong. :)

Hello,

I've been working on my CNC router, built from a Fine Line Automation kit about a year and a half ago or so. Everything is going great, aside from some backlash issues with the Z axis.

Hello,

I'm looking at a 1997 Thermwood 40 CNC. It's a great deal, but I'm concerned with the age of the control software- I want to be able to cut as fast as possible, complex 3d contours.
...

Thanks for the reply!

I don't think I'm going to be able to do what I want to do- the curvature has to remain smooth, so joining the edge of the mesh won't work. It would give me an odd profile...

Hello all,

I'm trying to model something to put out to my CNC. The ouput needs to be slightly undersized from the original, but the curvature of the top of the unit has to be the same.

Here's...

Hello all,

I'm trying to make a "1 penny touch probe" ( The "One Penny" Touch Probe ) to work with my G540. I have a regular 6 ball & 3 shaft kinematic from wildhorse designs, and I'm very...

Hello all,

Still having fun in the saga that is this router- for me, at least. :)

I'm having an issue with choppy motion in 3 axis. When I'm cutting in the z while hte x or y is moving, the...

I e-mailed this to Ahren with the photos I've included here a week ago and am waiting for a response, so I thought it might be better to get more thinking caps in on the action while I wait. :)

I...

Okay, to answer some questions-

1- I'm using the gecko g540 driver & motor kit that Nate and Ahren sell. PSU is 48V, motors 380 oz-in.

2- Table has no overhang. It is a single thickness of...

HELP!!! :)

I purchased a FLA kit in September of last year.

I have been working on this machine for almost a year now, tweaking things here and there, and still can't get the accuracy I expect...

Okay, why don't we break this down to simpler terms as far as reliability- If I was using my Unisaw (Delta 10" cabinet saw to those that aren't aware- not trying to be condescending, but some peole...

I have gone through 3 machines, all horrible in one way or another, no reliability, bought the Centerline (vector) text add on, and carvewright will not refund the add on, even though I did not...

Hello all,

I come to you a broken and frustrated man. :( I bought a Carvewright (compucarve) in late august. The second carve, the flex shaft burned through the sheath. Took it back, got another...
