no comment ! -6.660mm ??? with my mecanical comparator +-0.1mm default...

[MagoKimbra]

Sorry i do not understand!!!

[prophetmaster]

well it's just not possible that measures more than 1 mm of default on the bed

[MagoKimbra]

why not?

[prophetmaster]

because if I mechanically measured with a probe I find maximum 0.1mm fake on the bed! So how come you found it 6mm?

[MagoKimbra]

Respect to center, first probe is center this is zero...

[prophetmaster]

I did not understand but I want to know why it does not work?

[MagoKimbra]

ok write the G30 X0 Y0 command

[prophetmaster]

do I send you my config and you tell me if I'm wrong somewhere?

[MagoKimbra]

The firmware is a first probe to a center, and calculates the difference between the point the probe and the height. If it's ok should give 0. After various probes, and it calculates the difference between that point and the center. If the floor is not level by those values.

[prophetmaster]

I get this : Echo: Bed Z-Height at X:0.00 Y:0.00 = -1.0933

[prophetmaster]

and my config :

[MagoKimbra]

OK your High is correctly? Down width Z and check is nozzle touch the plain at zero...

[prophetmaster]

No there is 1 mm

[MagoKimbra]

Ok increment high +1 width m666 h command M666 h302

[prophetmaster]

Recv: Echo: Bed Z-Height at X:0.00 Y:0.00 = -0.0467

[MagoKimbra]

It's ok, now the 0.046 is possible error for Z PROBE OFFSET... Now when you give command G29 the firmware chek the center this point is zero.. When check another poin the value is differenze from center point... If you have big difference you must do the autocalibration width G30 A command...

[prophetmaster]

Ok i send a G29...

[MagoKimbra]

The autocalibration may take time. Can be up to one hour ... I'm going to sleep... Tomorrow i read you result..

[prophetmaster]

Ok me too, thanks for the help and good night !

[MagoKimbra]

This is center line probe Recv: Echo: 0.130 0.063 -0.003 -0.007 -0.033 -0.060 -0.123 -0.193 -0.273 Look the center point is ~0 but the extreme point front and behind no.. You have problem width delta radius... The autocalibration correct it..

[prophetmaster]

ok after some test G30 A G29 my sensor is not best for me !
