Change the lookahead to 200 and see if it makes any difference.

Laptops are not supported for use with mach3, because a lot of them won't work.

Copy the Mach1lic.dat file from the old computer to the new one.
It should be in the \Mach3\ folder.

A friend of mine makes guitar necks. With Mach3 and a UC100, his programs took 1hr 5 minutes. When he switched to the UCCNC control software (which controls the UC100), the same program would run in 45 minutes. Roughly 30% speed increase, and more accuracy. It appears that there are issues with the trajectory planner in Mach3.

One thing you can try is to increase the lookahead to a higher number. My froend says it increases the speed, but results in Mach3 occasionally rounding some corners.

You might be seeing resonance. Adding dampers to the motors may make it much smoother.

Something like this. After simulating, your left with an array of small rectangles, which is nothing like the actual part.

You don't have to add it for me, as I probably wouldn't use it anyway, once the novelty wore off.
But it would be beneficial in some instances.

Perhaps you could do it similar to how CutViewer works, where the stock is defined in comments in the g-code?

It chooses the stock to be the size of the job,
Say I'm cutting something like a board with box joints, with the board laying flat on the table. So I'm making a series of grooves in the end of the board.
Currently, the displayed stock starts outside of my actual stock, and stops at the point that my toolpath extends into the stock. If you need a visual, I can draw something up tomorrow. But right now, it doesn't give an accurate representation of what I'm cutting, because it's not showing my actual parts, but rather my toolpaths in an arbitrary piece of stock.

Without being able to specify stock size, I think it's usefulness is greatly diminished. But then what do you want for free.  ;)

Just my two cents (nickel in Canada, no more pennies). To be honest, in my 20 years of programming routers, I've almost never used a simulator. But some people can't work without them.

How about letting us specify stock size? The default stock doesn't really show what I'm doing.

Also, it doesn't use the correct tool. G Code tool # stays on tool 0, so I have to use "what if" tools and toggle to the correct tool.
My code has a T2 M6 in it, and Mach4 is showing tool #2 is in use.

A resizable window would be nice for those with 1920x1080 monitors.

Are you sure the speeds are the same. Both velocity and acceleration in motor tuning?
If they are, I'd uninstall and then reinstall Mach3.
