What's the full path? It should work.

Did you click on the colored box to set the color?

I didn't see anyone mention this, but the License Agreement specifically says that the license is NOT transferable.

Yes, but I'd use different bits for each, as after cutting MDF, a bit will dull quicker on other materials. And be sure to use a Compression spiral.

I have tried a 8mm spiral but wasn't impressed as the first cut into each panel would burn edge

That's what I mean about proper rpm and feedrates. If you're burning, you're cutting much too slow, or your rpm is much too high.

I'd recommend something with a larger diameter, 10-12mm. We use a feedrate of 20 meters/min at 16,000 rpm. At lower feedrates, you'd need to reduce the rpm proportionally, but there will be a lower limit for the rpm.

For flat parts, compression spirals are what you want. For maximum tool life, proper rpm and feedrates are required.

How much HP do your spindles have. Do you have a vacuum table? How big is the vacuum pump?

It's not XP, XP works fine.

What it sounds like to me is resonance. What kind of drives do you have?

You might want to read through this thread about making dampers to remove resonance.

You have the velocity set too high for the motors/drives you are running.  When the machine makes a diagonal move the actual motor speed has to be a lot higher than the commanded rate to create the  commanded feedrate.

Terry, when making a diagonal XY move, the two axis are actually moving slower than if they were moving in a straight line along the axis.




I see this problem come up every now and then, but have never seen an answer on why it occurs. My thought is that it's PC related. Open the task manager and check the CPU usage when doing your diagonal move and see if it goes to 100%.

If you set up different profiles, and load different screens in each profile, they'll each use their own screens.
