cofreakma

Hello,

can i use this BL-Touch from Geeetech on my DuetWifi?

please help me!

I have connectet to the 3 GPIOS on Duet, and this Working Perfect.

The two another cable (black and white) come to the Z-Probe connector?

This BL-Touch running with 5 Volt.

I need 3.3 Volts?

When i Measuring on the 2 Pins on the Board (Z-Probe) = 2.17 Volt output??????

Thanks all

2.17V is probably sufficient, and if not then you can use P1 instead of P5 in the M558 command.

Hi,

i have try this…. and works better.

I am using a BlTouch of Antlabs

I have conected White wire of Bl TOuch, in Z Probe Shocket_In, Red, Brown and Orange, in expansion socket.

And i have try this, in config.g, i have put:

[[language]]
; BL-Touch
M307 H3 A-1 C-1 D-1 ; BLTouch - on heater 3 pin
M558 P1 X0 Y0 Z1 H3 F200 T5000 ; Homing Z axis, P5 for BLTouch
G31 X-22.00 Y7.0 Z1.5 P5 ; Set the probe height - reduced P25 down to P5 - no difference

With this… i can manual control BlTouch (Extend, Retract and Test), and the advance, now i can read in frontpage of Duet control in Z Probe, the Z-Probe=5 when probe retracted, and Z-Probe=0 when probe deployed

If i try to calibrate, don't work...

Cofreakma. Can you read in front page another values of Z-Probe, when deployed or retracted?

cofreakma

yes i can read another values

To test a Z probe, use a simple G30 command. That should probe the bed at the current XY position. The Z movement should stop when the probe is triggered.
