How much did you reduce them by? Try reducing the accel by 50%.

Mach3 doesn't work in Windows 98.

With the type of code that Cut3D outputs, which is LOTS of short segments, your Z axis acceleration will usually have the greatest effect on velocity. The issue you're having is that Mach (dictated by physics) just can't change direction fast enough to maintain the commanded velocity.

General Mach Discussion / Re: Hesitates with tabs in profile toolpath

In your first post, you asked about why the tabs were present on every pass. The answer to that, is that it's just how the algorithm that Vectric uses works. It's apparently something that they can't easily change, so it's been that way through probably every version of Aspire and V Carve Pro. It's Vectric's opinion that this shouldn't be an issue, and I tend to agree.

I read through the posts you linked to above. I think that the issue here is a possible bug (or limitation) in Mach3's trajectory planner. I've run into similar situations where Mach3 would  "hesitate" at a transition from a straight line to a tangent arc. Technically, it shouldn't, but I've seen it happen.
Which means that there probably isn't a fix to your problem. Unless you can find some magical combination of CV settings that helps.

I happen to be a beta tester for Aspire. A few years ago, one of the other testers knew of several people experiencing what you are. Several other Mach3 users did not experience the problem, and claimed the issue was caused by CV settings. I just went back and read through the messages, and no specific settings were mentioned to eliminate the problem, and the original poster never followed up with any resolution.

So, unfortunately, I don't have any answer on how to eliminate it. I never use tabs, so haven't come across this issue.

What do you have Stop CV on angles< set to?

The driver box IS definitely receiving the pulses because the co-ordinates on the screen change in sync with the changes of the co-ordinates on the mach3 display.

Do you mean the toolpath is displaying movement?
That doesn't mean the drives are receiving the pulses. My guess is that your port address is wrong, or the pin settings are incorrect. If the drive was receiving pulses, the motors would either be moving, or at least making some noises. My guess is that the drives are NOT receiving the pulses.

I have no idea, as I don't use a metric profile.

Make sure CV distance and CV feedrate are off, and increase the lookahead if it's set at 20. Not sure if these will help or not. I've seen others ask this before.
