How can I clean a nozzle? I think its full or something. The tube (hot end?) before the nozzle is that also to clean?
Usually, if you heat up the nozzle to 200C, you can push out old filament with new filament. If it was printing a different material, eg ABS or Nylon, you may need higher temperatures, eg 230-240. Don't leave it at this temperature when the PLA goes through.
The feed tube may also have filament in it, it just means you have to push more filament through. Or you can detach the feed tube from the top of the nozzle, and pull the filament back out by hand. To take off the tube, shows this in the pdf manual.
If you can't push filament through at all, you may need to diassemble the hot end. Unfortunately the manual doesn't seem to cover this.

@droftarts Nozzle was defect. I changed it and now extruding works.
And I still confused about the leveling. Do I have a Z probe? Or did I configurated it as something else?
In web controller is the Z-probe 0 and goes to 1000 as you managed.
After pushing the button "Delta configuration". The nozzle hamers the bed. What do I need to do to get the leveling right?
The Commissioning document is very confusing. -
@droftarts
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

;G31 Z-0.700You'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.
G31 K0 X0 Y0 Z-0.7The steps for testing and calibrating a probe are here: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_testing

@Phaedrux
After delta calibration (button) the z is made 0 again. But The nozzle tip is about 6mm above printbed.
I did :
M564 S0
G30 S-1
G92 Z0
G31 adjustment in the code
many times. After calibrating it is again off.
I think my height in config (override config and homedelte) of Z320mm is wrong. I also tried 300, 310, 315. It is still going wrong.
What am I missing?Spec of tractus 3d t650p says:
Build Volume with Lexan (mm) 170 diameter x 285 height (315 center)
Build height 300 mm (11.8”)When I print benchy. The print is not what it should be...
-
@Phaedrux It's still not clear to me what kind of probe I have got. If I have the configuration right for the probe I have declared now (see history). Something is not right. Also mesh compensation is doing strange things. I think I declared it right for my Delta : M557 R100 S10. But the nozzle goes down and to the x axis and off the bed.
-
Did you change your steps per mm as droftarts suggested?
M564 S0
G30 S-1
G92 Z0Can you describe more clearly exactly how you're measuring the trigger height for the probe?
Have you gone through the probe testing and calibration steps from that link earlier? For instance, have you confirmed that you can stop Z movement during a G30 by taping the bed manually? As in, does the probe seem to be working?
