I've seen that same behavior. In fact, if the spindle is turning at full speed, hitting cycle start a second time will slow it down to 250 RPM.
I can't tell you why, but I can confirm that it's not just your mill that does it.

Every once in a while when I hit the cycle start button, I will accidentally hit it twice. When this happens, the spindle has started to engage, but as soon as the table starts to move, the spindle will turn no faster than it is turning at that instant.
If the spindle is up to 200 RPM when the axis begins to move, that as fast as it will go.
WHY?
You can buy good parts or you can buy cheap parts, but you can't buy good cheap parts.

I'm glad to know it happens to other people, but I'd still like to know WHY.
Maybe the folks at Tormach will chime in and tell us why this happens.

The Cycle Start button just points to the Mach3 "Run" function. There's no script involved. So it's not a Tormach issue at all. It's a Mach bug.

Yes me too. Read the bottom for a script error, or wrong pulley (can't remember the exact name) warning. I have to reboot the computer to get my machine back in running condition.
I just tested that. The message is "Too slow for pulley. Using min." which means that something was trying to set the spindle speed to less than the minimum of 250, or 100 if the mill is in low gear.Originally Posted by twocik

Happens to me also.
Would like to see a fixed.

I sent my question to the guys at Tormach and Daniel Rogge replied back with the following message:
The behavior you describe is a Mach 3 bug that the authors of Mach have been aware of for some time. They may have fixed it in the current release (it’s not mentioned in the release notes, but they’re not the most thorough company with respect to release documentation) but there are other larger issues with the current lockdown release of Mach that prevent us from moving to the current version. The version that we ship with the machines (3.042.029) is what we consider to be the most stable version of Mach. Unfortunately it has a few issues, one of which is that double clicking on cycle start will result in the S word being reset to zero. That’s why you see a “too slow for pulley” message, and the spindle starts at 250 RPM.
I do have a workaround for you – the time between clicks on your mouse that your computer “sees” as a double click can be adjusted in Start>Settings>Control Panel>Mouse. If you find that you’re often accidentally double clicking the button, you may set your mouse to the max double speed setting to greatly reduce the frequency of accidental double clicks.
You can buy good parts or you can buy cheap parts, but you can't buy good cheap parts.
I just tried the workaround that Daniel Rogge sent me and it worked beautifully. I double clicked on the cycle start button and it performed just as if I had single clicked it.
Thank you Daniel for your help.
