LOTS OF BUR ON PRINTS Hello All, I have tried printing the calibration files and the results were excellent, while went ahead for printing a model, and seems lots of BUR on the printed result. Slicr latest version with Infill 0.4 and the speed at 60mm/s Also it looks that when the printer hotend travels the other end or change positions, there is trail of plastic, which is causing the BUR. Attached image for better understanding. Any suggestions to improve the printing quality. [attachment 28329 ENGINE_lowres.jpg] Thanks in advance.

Im not sure whether I need a extruder calibration for better flow control.
If you haven't calibrated your extruder previously, then this definitely needs to be done. In the image it looks as if you are way over-extruding.]]> NewPerfection Printing Mon, 10 Mar 2014 16:54:37 -0400 https://reprap.org/forum/read.php?262,322529,322551#msg-322551 Re: LOTS OF BUR ON PRINTS https://reprap.org/forum/read.php?262,322529,322551#msg-322551 pingnagan Printing Mon, 10 Mar 2014 05:30:44 -0400 https://reprap.org/forum/read.php?262,322529,322544#msg-322544 Re: LOTS OF BUR ON PRINTS https://reprap.org/forum/read.php?262,322529,322544#msg-322544 jkoljo Printing Mon, 10 Mar 2014 05:18:28 -0400 https://reprap.org/forum/read.php?262,322529,322529#msg-322529 LOTS OF BUR ON PRINTS https://reprap.org/forum/read.php?262,322529,322529#msg-322529
I have tried printing the calibration files and the results were excellent, while went ahead for printing a model, and seems lots of BUR on the printed result.

Slicr latest version with Infill 0.4 and the speed at 60mm/s

Also it looks that when the printer hotend travels the other end or change positions, there is trail of plastic, which is causing the BUR. Attached image for better understanding.

Any suggestions to improve the printing quality.

Thanks in advance.
