Hello, I try to get a 3DTouch ABL Probe v3.2 from geetech running with my Ender 3 V1. My general problem is that the probes red light is flashing and the probe seems to be not regnocize by the firmware.
Wiring:
I wire the 3 color wires to a 27 pin connector with the ender mainboard. From another printer with the same probe I know, that I have to wire the three cables vice versa. Wiring it normally cause a flickering display. Wire it vice versa, the display works normally. I also wire the black and white cables to the z Endstop on the mainboard. Already try to wire them vice versa. No luck!
Configuration:
I edit my config as seen in the klippy.log. I playing around with #pin_up_touch_mode_reports_triggered: False, #pin_up_reports_not_triggered: False and #probe_with_touch_mode: True also set the sensor_pin from ^PC4 to PC4. Nothing seems to help.
Sending BLTOUCH_DEBUG commands have no effect on the probe. Only getting a Ok back.
At this point I have no idea what to do. Anyone else?
Okay. Can you give me a hint what I miss? If you mean that I add the printer.cfg from the log, in this case it think I could be helpful to show how I configure the probe.
While your pins look okay, there are reports that the board is kind of picky when it comes to the BLTouch / Clones: Ender 3 pro v1.1.4 main board + Bltouch
Do you use this adapter stuff?
Yes I use a 27 pin adapter. I disconnect the display cable from the mainboard and plug it into the adapter. Also connect the 3 pin cable from the bltouch to the adapter. After the assambley I connect the whole adapter with the mainboard display port.
I check all PCBs of bad solder joints and the correct wiring. All seems to be good. The only think that I can recognize is that the voltage supply on the adapter is 4.8V. But how to simply increase the onboard voltage?
For a better description of my problem I attach a picture of the probe with the little red flashing LED. At boot of the printer the blue led flash one time less then a second and after that the red light appear.
I also swap this probe with one of my other printers probe. Works fine. So the probe at all works.
Okay. The last days a lot of things change. I brick my original ender 3 mainboard while mesearung the voltage on the PCB DAM!.
Okay don’t give up. Order a new original creality 4.2.7. silent mainboard with 32bit, hopping the Probe will run on it instantly.
I plug in all cables into the new mainboard without connection the probe. First test the plain hardware with the stock marlin firmware. Everything works fine. Stepper motors, heating, the display and so on. Next flashing marlin with bltouch support provided by creality on their website. Connecting the probe on the given bltouch port. Oh nice, the probe seems to be work. At boot it moves two times down an up. After that the led lit red but try to controlling the probe from the display has no effect .
Because of the complicated workflow compiling a new marlin firmware I decide to switch back to klipper. So I compile the firmware, flash it with the sd card, edit the config and see what happen!
Also everything works fine. The probe act like described before (moves tow times down and up, lit red). I try to solve the initial test with the BLTOUCH_DEBUG commands but they has also no effect on the probe. I play around with the config and the options described here: https://www.klipper3d.org/BLTouch.html#bl-touch-clones. No chance. The probe stands still.
DAM!.
