Slow motion and harsh noise

[Marcin81]

Hi to all,
I need some help with setting up my mach3 configuration. I read almost every post that I could find on the internet but still can figure it out what's going on. The problem is that when I jog the machine it moves smooth and fast but when I load g code for profiling the motion slows down and motors makes a lot of harsh noise. I tried different motor tuning configuration and also many other settings but no luck at all. Some specifications of my setup:

PC:
Processor: Pentium 4 - 3.2Ghz
Ram memory: 2 Gb DDR2

Cnc
Controller: Tb6560 board
X axis: Nema 34 step motor, 8 micro steps, 16mm screw, pitch 10 mm
Y axis: Nema 23 step motor, 8 micro steps, 16mm screw, pitch 10 mm
Z axis: Nema 23 step motor, 8 micro steps, 16mm screw, pitch 5 mm

Here you is the link to short video where you can see and hear what's going on with the machine when jog and when start working on the profile cut.
YouTube - ‪cnc‬‏I also made screen shots of my mach3 configuration.

Thanks

Sounds like resonance. Try jogging at slower at different speeds, especially slower, and see if it does it then. If so, it's probably resonance. If you have dual shaft motors, try making some dampers.

Hi Gerry,

Thank you for the replay. The machine acting like this in every speed. Every time when I import g-code with with curved or 3d profile it is this same.

Thanks,
Marcin
