General Mach Discussion / Re: Steppers and machine sounds bad, but not when rotating the toolpath

This problem seems very backwards, if the steppers are missing steps then surely when I rotate the toolpath there is even less time given to the drivers and surely should get worse and not better?

One thing I have noticed is that when you are rotating, the DROs don't update. In fact when the DROs are updating the steppers are noisy and when they aren't updating they are fine. Could this be anything to do with it?

When I say rotate the axes, I mean rotate the 3D view of the gcode that is displayed in the program, not actually changing the coordinate axes of the model I'm cutting.

So when I jog in just the X axes, it makes a rough sound until I leftclick with the mouse and rotate the toolpath when it becomes smooths. As soon as I let go it's rough again

When I run the DriverTest.exe file I get a "System Excellent" with only ever 5 spikes on the line max.

Okay I have:

Reinstalled to 0.62 - no change.
Changed the parallel port to EPP in BIOS - no change

I'll keep an eye on that other thread

Really banging my head against the wall with this!

Thanks for the help

I'm on 0.66 version. The link you posted doesn't work but I'll have a look for another now.

Unfortunately I don't have another computer with a parallel port so testing with another PC is not really possible.

I'll have a look into the EPP Bios settings

Okay great, I'll look in the morning when I'm back with the machine.

Cheers,

I took this video to demonstrate. You can't hear all the bad noises but you can tell that something doesn't sound smooth. The first two runs are without rotating the toolpath and the second two are while rotating the toolpath (when I put the camera down)

Okay just tried on half current, didn't seem to make a difference at all
