Hi guys,

I bought vibration dampeners in order to try to reduce the noise of my 3D printer.

According to videos made for other models of printers, there should be 2 hex screws on the axis of the motor. They need to be unscrewed in order to make the axis longer.

There is no screws on the axis of ...

If you are printing a single colour make sure the other 2 filaments are pulled out of the hot end slightly. I found that it was causing issues with retractions not relieving the pressure in the hot end. Made an instant difference when I realised after doing the multicolour test print.

I now have ...

Thanks.

Hi,

Can someone explain with pictures how to remove the extruder nozzle please ? I would like to replace it with a clean one.

how about getting 2 magnetic covers for the bed glue one down on the hot bed with the correct polarity so to attract the other then you can do the same without buying a new magnetic heated bed or am I being dense and not understanding the problem


Since my last post I bought a Ziflex magnetic ...

I have the same issue. I reduced the temperature to 180°C and still have this issue.
Could it be caused by the quality of the PLA?

Yes it affects extrusion. There is too little extrusion.

How do I contact after sales?


On a related topic, I had to modify the extruders Start G-code in order to use different colors. See an example below. I don't understand why this was not included in the official settings.

Hi,

Thanks. I removed the code you mention from "Start G-code" and it is using only extruder 1 now.

I have 2 questions.

1. How can I tell the printer to use only extruder 2 or extruder 3 and not extruder 1?

2. I noticed that one of my extruders is different from the others. The "wheel" is flat ...

Hi,

I also have issues with colors. I don't want to mix them, I want to switch between them.

In Cura if I choose extruder 1, it will use a mix of all of the colors. If I choose extruder 2 or 3, it will do weird stuff, like print in the air and then show a Low temperature error.

Hi can anyone tell me if there is a magnetic hotbed available for the A20T as I have great difficulty removing models from the heated bed after completion, I have the reheat the heated bed and then it is a real struggle to remove the model it is so hard that I am afraid that I am going to damage ...
