Machine Operation and axis test was created by jjharley
When operating on axis test (velocity and acceleration tuning) the machine runs very quiet and smooth,
but when running the "Linux CNC' logo in gcode you get a lot more noise.
Could it be an effect of the 'decay' setting (slow), or is it a factor of the gcode itself.

I would imagine that if _everything_ else is the same then it must be the slightly different motion from the G-code. The LinuxCNC logo has a fair bit of starting and stopping.
However, it _might_ be because your power supply is marginal when it comes to trying to move more than one axis..

Thanks
24.4 V but have noticed that it will drop to 24.3V, keep a digital voltage meter attached and on when cutting.
(this is only a 24V max power supply but they tend to have a little 'play'.)
two 2.5A and one 2.8A NEMA 23's all of them set to 1.6A
driver board is TB6560AHQ chips
