At Z=11 it touches the bed. I followed the steps for trigger height with g92/g30 . Then used G31 and put the z number (trigger height in config with G31 x0 y0 z-2.0 Is that right? -
@droftarts I am done. It will not work. After setting a z=0 (nozzle touches bed) delta calibration is not working proberly. The Z is suddenly 32. When calibrating the nozzle pushes the bed in 3 of the 6 down leveling. What I'm missing?

@dc42
Can you help me with bed leveling in my Tractus 3D t650P. After getting the firmware right and configuration my Z is off. When Z=11 then crashes the nozzle in the bed. I made may changes with G92 Z0 etc. G30 S-1->G31 and M500/M999. With G31 z-10.85 nozzle is still crashing with Z<11 -
Were you able to identify what kind of probe is actually being used? Can you point to a piece of hardware on the printer and say "this is the probe"?

@Phaedrux
I Will dismantle the bottom to see.
I managed to print something unless the nozzle hitted the bed. But It was very small and didn’t make It as a benchy. Looked the size of 20% of the suppoost size. -
@Phaedrux @droftarts
you tell me haha
Do you know how I set this right in the config.g?
Please help me to get the calibration right. Every time I push "delta calibration" my previous (G92 Z0) is changed to something else (Z=0 but nozzle is about 6mm above bed). -
@droftarts
This is what is going wrong with printing. It had to be a sqaure 50mmx50mm h=20mm
Result 20mm x 15mm

I think that's probably a bed attached piezo probe. It detects the nozzle contact tap.
You won't be able to print anything until you have the probe configured and are able to complete a delta calibration and bed mesh. Without an accurate mathematical model of your delta nozzle positioning won't be accurate enough.
Can you get a clearer shot of that little PCB? As well as a photo and description of where the wires from that PCB are connected to your Duet? With that information I can hopefully guide you in configuring it.
-
Also please share your entire current config.g and homedelta.g and bed.g

@thomasvanderwal sorry, I’m away on holiday this week.
Did you check that, from homing, when you move down 50mm in Z, it actually moves 50mm? Measure with a ruler. This is to check your steps per mm (M92).Ian

The 3 wires go to the E0 Endstop on the board.
The stepper for extrusion and retracting is attached to E0 Stepper

@droftarts
It seems that with 50mm the nozzle only goes 25mm down -
@thomasvanderwal change this line in config.g:
M92 X80 Y80 Z80 ; configure steps per mm
to
M92 X160 Y160 Z160 ; configure steps per mm
Then do the same test again.
Most likely you have 0.9° stepper motors (400 steps per rotation, check by looking on the back of the motor) and what looks like 20 tooth pulleys (you can check by counting the teeth) and GT2 belt (2mm belt pitch). Steps per mm = (motor_steps_per_rev * driver_microstep) / (belt_pitch_mm * pulley_number_of_teeth) = (400 x 16) / (2 x 20) = 160

You'll want to configure the probe offset. In your case the X and Y distance is zero, because the nozzle tip is the probe point. The Z value will need to be calibrated. -0.7 may be accurate. The value is negative because the nozzle is pressing into the surface of the bed slightly.
