Troubleshooting from a picture.

[HajduR 0]

Dear All,

 

I recently bought a used Ender 3. 

Since then I changed a thermo sensor (thermal runaway) , the bed (from glass to magnetic), the nozzle (0.4), leveled the bed - probably badly, tightened a pully and the x axis was loose a bit - I fixed that with the eccentric bolt that holds the lower bearing.

So I am new, learning as I go.

 

I am not satisfied with the print quality and I think the problem lies in me. My inability to set up the machine right.

Please take a look at this picture. I think this is the first layer. Big gaps on the print. The plastic is sticking to the bed as you wouldn't believe, it is really difficult to get it off. I am using the filament I bought with the machine, maybe it is bad quality and I have to change that... I don't know.

 

Can you help me troubleshoot? What should I do to improve print quality?

 

Thank you

Best regards,

 

Robert
