@infiniteloop Try it your solution, but for whatever reason it doesn't work. At the startup the pump starts.

Not a big problem,

Thank you for taking time to answer and help.

I had time today and installed the pump with the flyback diode. I choose to use Fan0 instead an unused heater. Everything is working properly and the pump is not noisy (used F25500) which is recommended by more experienced members. The only annoying thing is when I start my printer the pump starts also and I need to shut it down from the fan button.
I used M106 P0 F25500 L60 B0 C"cool" and changed L60 to L0, but no effect. What should I do to make the pump not to start at the printer start up?

Thank you

@infiniteloop I read a post from David saying I can use a heater output to connect the pump. It will be easier than a fan? I have a flyback diode and I think I still need one. Thoughts?

Hi just took a delivery (9 days from China to UK) for a 12V berd air pump. What and where do I need to connect and use (safely) the pump with a Duet wifi ver 1.04c?

Thank you

Hi to all,

I need a PT100 sensor because the old one failed (one wire detached from the barrel) . I found one on 3djake, quite expensive, but I bought it. My questions to more knowledgeable people:

• can some other sensors be used (same family PT100)?
• where I can find that type of "replacement" sensors?
• there is a way to reinforce the sensors from e3d or other vendors?

Thank you

@Danal
The machine is calibrated, I think. I will do it again today after work. PT 100 don't give any warnings. Thermal tuning saved with a M500.
On both attempts I saw the same behaviour, the first 15 layers are laid down beautifully. Starting with layer 16 where the infill is almost finished the gaps appear. It looks like the filament don't stick anymore on the previous layer.
Why is that?

Hi David,
I was thinking about that and actually tried, but the extruder start skipping like the PLA was not melted properly.
I will try tomorrow with a lower temp.

1. Any advice for doing a better calibration besides the measurement method?
2. "Nimble (biggest crap ever)". Why is that?

Nimble is on the way. I still use the original extruder with Capricorn tube.

Hi to all,

I have a Anycubic linear plus with:

• duet 2 wifi board;
• hayden rods;
• smart effector;
• PT100;
• ultrabase;
• on order a Zesty Nimble V2.
  I fight with this crappy prints for over a month. I really need help with some settings.
  I use Simplfy3D and a have:
• bed temp. 70C;
• hotend temp. 210C;
• nozzle 0.4mm (brass);
• extrusion multiplier - 0.95;
• retraction 5mm;
• speed retraction 3000 mm/min;
  -layer height 0.15mm;
• first layer - height 110 - width 100 - speed 55;
• raft;
• no fan.
  Printer is calibrated (I think, maybe not). No warnings. Z probe working properly.
  Why I have this terrible results? See photos
