I'm coming from Aspire, where when you set up the material it would ask, where do you want your start point, in the corner, or in the center. For the life of me, I can't figure out how to tell...

Any idea what might be causing the rough edges Illustrated in the video above? I tested my X & Y, by having it cut some circles and straight lines of different lengths...

Thanks for the response. The carving represents an already exaggerated version of MI's topography. It's awfully flat here. https://tangrams.github.io/heightmapper/#7.25/45.086/-81.713

All I could think of is shellac, followed by gel stain, wiped off the high points with mineral spirits, but when I tested it, I thought it looked a little muddy.

Muddy Mess:...

That was it, Ger, thanks--I didn't have the ESS plugin properly installed. That, an XML file Dan Mauch sent me on Saturday and the motor tuning images GhostXL posted for me however long ago and all...

Eight years or so ago I built a Fineline Automation FLA-200 kit with the 4 axis nema 23 kit from cncrouterparts.com. Dan Mausch built the control box. With help from all of the above and this forum...

I'm going to resurrect my own thread. Anyone know what the FLA-200 Mach3 motor movement profiles look like for the steppers? Had a hard drive crash and am trying to get it up and going again.

Even more intimidating than the price is the prospect of the learning curve. Honestly, I thought Aspire could handle everything--it's cost alone would lead one to believe that!

Rhino 3D

In particular, I want to carve ukulele necks (and other bits, like bridges and sound boards). I've been struggling in Aspire and I'm starting to wonder if it's the best choice for what I'm trying to...

Sorry--ended up posting this twice by accident. I'd delete this one if I could!

Here's the other one.

What software should I get for this kind of work?

Trying to set up aspire to carve a board with both ends raised up, one through lamination, the other an angled scarf joint. Problem is I don't see a way to tell aspire the shape of the work piece,...

Thanks, think I'll try that. It's a big hole, though, so I'll go the bondo route...

Well, 1/3rd of the way through the first tool path, a combo of the rough cut and first fine pass with a .25 ball end, it decided to plunge all the way through the work piece. Made a horrendous noise...

Well, thanks for all of the advice. I got it down to 16 hours, and started the routing this morning. Fingers crossed. The first one cut usually is a learning experience!

I've got the roughing down to four hours with a .25 ball end and 40% stepover. I could probably push the speed (up to about 140 ipm), but I've found it's not as clean of a cut when I do that, and...

So, this has never been a problem for me before, but this is the biggest job I've attempted, a 3D carving, and looking at the TMT, it either says 65 minutes, which seems pretty short, or 65 hours,...

I spend more time trouble shooting the s.o.b. than anything else, followed by ruining parts. Any suggestions for a hobbyist machine with a reputation for reliability?

Just a little more info, I'm...

And that wasn't it. I installed the dumpster acme nut and it's still doing the exact same thing. I don't believe it's the G-code as it looks fine in Mach3, so it has to be the hardware, right?...

Yeah, Nate needs to create a communications/help desk division, and then hire someone to do that. Last email I sent, months ago now, never received a response.

According to Ahren of cncrouterparts.com, if I'm using the original one piece acme nuts, that could be the problem. I replaced the original acme nut on the z axis a while back, so I'm going to do...

Check it out, my fineline automation FLA-200 (2x4) machine used to cut perfect circles, but suddenly it does this:

Is that the product of backlash? How would I...

Also--not sure what possessed me to say the .0625 bit I was using had a half-inch of flute (which would be more than enough!), it has .350, a little less than 3/8.

Thanks Victor. I use Rhino, which isn't a parametric modeler like you appear to have there (not sure what software you're using). So I start with curves and then essentially loft or sweep to create...

I did remove the file. I put a lot of time and research into creating the model and don't want to give it away without at least thinking about it some first. And I did project the vectors onto the...

And, it worked! Thanks for helping me thing about it.

Actually, having examined the original 3D model closely, it looks like I only need a little less than 3/16 of flute to cut the f-holes now that the inside and outside are carved, if I told it to...

Thanks! Unfortunately my .0625 end mill only has a half inch of flute. My next largest end mill with enough flute is .125, which will mean I'll have to finish out the finer parts by hand. Still...

I have carved a ukulele archtop plate (more or less identical to an archtop guitar, only smaller). I made a 3D model, imported it into Aspire, and made two separate files from it, inside, and...
