You didn't answer the most important question.
What macro?

Are there any messages displayed when it stops?
What version of Mach3?
What macro are you using?
Are you using the parallel port? If not, which motion controller?

The UB1 breakout board only works with the ethernet UC300ETH. it won't work with a USB UC300.

No, I don't have a scope, or even know how to use one.

Since I won't be running the motor anywhere near the speeds I was testing at, I'm not too concerned about it.

It's not the breakout board. I'm using a UB1, which is based on the MB2, that was designed to work with the ESS. It's an excellent, high quality breakout board.

When I get a chance, I'll wire up the DMM servo I have and do some more testing at high pulse rates.

I recently ran into an issue with a Leadshine AM882 drive.
I was just doing some testing with a single stepper motor on a test bed.

The drive has a max input of 200Khz. When I set the UC300ETH at 200Khz, the drive wouldn't see the pulses correctly when the pulse rate went over ~130Khz. But with the UC300ETH set to 400Khz, I was able to send pulses right near the 200Khz limit of the drive.
I was spinning the motor over 3000RPM with 1/16 microstepping.

The USB UC300 has a max pulse rate of 200Khz. The UC300ETH goes up to 400Khz.
I use the UC300ETH, with a UB1 breakout board, which has differential step/dir.

Which UC300 do you have, USB or Ethernet?

Not sure what that is, but it's not g-code.
Where did this file come from?

There is a known issue with Feedrate Override, if you use it to increase feedrates by a large amount.
It's best to program higher feedrates, and turn it down to start with. I would not try to use it above 150%.
