Motors are not running quiet
-
If you have 1.8 degree ungeared motors directly driving 20 tooth pulleys the steps per mm at 16x micro stepping should be 80. If you use 16 tooth pulleys, then the steps per mm should be 100.
Z depends on the lead of your lead screws so without that information, I can't say what they should be.

You´re right. If I count i like http://reprap.org/wiki/Triffid_Hunter%27s_Calibration_Guide#XY_steps I got 80 steps/mm
But my first issue is left. Drivers won´t work in interpolation mode. Noise is like A4988
-
Are you getting the correct amount of movement now, and in the correct direction for all axes?
-
I´ve changed to 80.16 an it seems to be ok but not quite
-
There should be a large difference in the motor noise between x16 microstepping with interpolation on, and with interpolation off.
You can also try increasing microstepping (but interpolation only works in x16 mode). If you put the changed M350 command after the M92 command in config.g, or you send it from the command line, then you won't have to change the steps/mm in M92.

I´ve tested today again and I can hear a different noise with Interpolation on and off.
Tomorrow I will test some different speedsTanks for your help
-
What speeds have you been testing with so far, and what are the steps/mm ? Microstep interpolation doesn't work at very low or very high speeds, but it works at speeds in the typical range for 3D printers. I'd like to get to the bottom if this just in case there is a firmware or hardware bug affecting it.

I tested with 1000 mm/min quiet | 7000 mm/min more noise | 12000 mm/min bit more than 7000
I guess it is ok and my tough was confused because wrong microsteppings
Thank you for kindly support

I have noticed that microstep interpolation is far more successful at reducing motor noise at low speeds than it is at high speeds. This isn't surprising, because at high speeds there isn't time for the chip to do high microstepping. For example, my delta has 200 microsteps/mm at x16. At 100mm/sec this gives a step pulse rate of 20kHz, which is half the chopper frequency. So the maximum theoretical microstep rate at this speed is x32.

Ah I see. It makes sense.
Thanks David
