Basic Information:

Printer Model: WANHAO D12
MCU / Printerboard: MKS ROBIN NANO V1.2
Host / SBC RASPBERRY PI 4

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

kindly assist with setting a 3d touch, i have used all the correct pin out and sensor details but it does not accept the Query commands, i seen on the "clone " section and seen pin_up_reports_not_triggered or pin_up_touch_mode_reports_triggered but i am not sure where to add these or what to do next i have added the klippy log as well as the printer.cfg file please assist.

The BLtouch section looks legit:

[bltouch]
sensor_pin = ^PA8
control_pin = PC4
x_offset = 26
y_offset = -2.9
stow_on_each_sample = False
probe_with_touch_mode = False
z_offset = 0

Have you checked the wiring?

The 3 wire cable has to go to the BLtouch connector on the board and the two wire cable (according to your setting) to the Z+ endstop connector.

Hi there

yes i have double checked the wiring, the 3 wires are at the BL touch points and the 2 wires are at z+

Unfortunately the cables are not colour coded, so it is hard to decide if the plug is in the wrong way.

I did plug it in reverse but it came back with an error failed to read state when I plugged it back it gives the error failed to deploy

You may check if the black wires are connected correctly according to this:

Checked it all and the pins are in the correct place from 3D touch to the board they are actually on PA11 I’ve changed the pin output but still no luck

[moewzy]

I managed to get to probe working when I use the query_probe pin up , it goes up and when I use the query_probe pin down it goes down but when I try to home G28 it reports failed to deploy BL touch and the probe is coming back as triggered after I use the command Query_probe

[moewzy]

solution was that the z-end stop was not plugged out and the 3d touch was in the pin above so all i needed to do was change pin allocation and it worked.
