Heating failed & Dual Extrusion not working

Post by krmmr » Wed Aug 21, 2019 8:21 pm

Now after i tightened the knob at the extruders and set my e-stops/mm to a higher value i get "fine" extrusions..

BUT

After some time the printer stops saying Heating failed. I tried printing the dice two times, one time it put out this message on the 2nd or 3rd layer the second time it stopt at the 10th or something like that.
I used CURA 4.2.1 to slice it. My A20M is only one month old and i did not get any good prints with it yet.. except the dog..

My other Problem is that the first layer is correct (white outside and gray dots for the dice) but every layer after the first is inverted? I dont know why.. Used a large Primetower which definitely wipes all old material..

Hi, You can check if the thermistor wiring of your hot end and hotbed is fully connected.
Then measure the thermistor.

You can try to re-slice the model.
From your print model,
You may need to 1.adjust the printing speed and reduce it appropriately. The reference range is 30-60mm/s.
                     2. Check the tightness of the belt;
                     3. Check if the bearing and the pulley are issued (the card can be lubricated for lubrication).
I hope this can help you.
