What's your paint process for MDF? Hands down the best finish I've seen.

On the download page for the C76 is a plugin that will show you where the fault is in UCCNC.
Here's an example video of it.

You...

Depends on the types of cuts you are making. Generally, harder wood will cut cleaner. I find poplar to be quite difficult, but it depends what you are doing with it. Also note that poplar can vary...

My guess would be a mechanical issue.

Fusion 360 is free for personal use, with limited features.

Anything significantly cheaper will be an inferior machine. You really do get what you pay for.

Here's one alternative. PDJ Pilot Pro CNC router kits, parts, plans, assembled 3D printing...

Try setting PD070 to 1 for 0-5V control.

±500 RPM isn't going to make much difference.

On my Huanyang, when using analog control, I had an RPM variance of ±1000 RPM with a steady analog...

LOFT has an option for solid or surface.

No, they should be fine for a Taig.

Use a profile cut with a single vector set to ON the vector.

Are you using the correct post processor?

Spit the gray piece in two by making a copy and using slice, then use intersection on the one half and union on the other?

Do you have them wired bipolar parallel?
You probably wouldn't see much difference going to a drive that can supply the rated 4.2a, unless you also increase the voltage to around 70V. And at that...

Is it a flat table, or pod and rail machine?
Make sure the vacuum pumps and drilling spindles all work.
Is all the software included, and do they g=have backup copies? If you buy it, you'll want...

If you are trying to get the most speed, you need to increase voltage to the motors. Different drives won't make that much difference.
Different motors can make much more difference than different...

I can't believe that rust would have caused that, especially after 15 minutes of run time. If it was rough enough to break them, it would have been very loud from the start.

Ours were actually much quieter. I guess ymmv.

Your controller may not support proper slaved homing.

I just replaced the vanes in our two pumps, and the new vanes come with the beveled edge. You can probably flip them, but you'd probably get a lot less vacuum until they wear in.
I would expect any...

No problems with your model either.

Should be something like this.

1) What is 320NM? NM is a torque rating. If it's 320 Newtons, that's about 72 lbs, which is higher than you'll likely ever see.

2) It really depends on the drives, and without a torque curve chart...

Get a UC400ETH instead of the UC100. It's more powerful, more expandable, and has much better noise immunity than a UC100, for only about $25 more.

I just made a similar model to yours, and it works fine.

You're doing something wrong, but I'm not sure what it is. If you can upload your model and Aspire file, I can take a loot at it.

And what does the toolpath look like with those vectors selected?

Do you just have one perimeter vector selected, or are there vectors in the holes that are also selected?

Is it doing the exact same thing, or just not cutting all the way through?

Does Cut2D support toolpath templates? You're going to want to use those.

It's been years since I used it, but I always found DesignCAD to be much easier to use than TurboCAD. But I'm sure they are both much different today than when I used them.
They used to be developed...

You would set work offset in WinCNC. There are probably several ways to do it, but the most common is to jog the machine to where you want the origin to be, and zero the X and Y axis. You want the X...

DesignCAD used to be decent, and was pretty cheap. It's the first CAD program I used about 30 years ago.
