Re: Improving by replacing parts

- Keep the printer as a bowden extruder and change the default extruder drive to a Bondtech BMG, it has a substantially better torque and traction than the default extruder. Hello, My experience with this extruder was quite frustrating. It really works and it's impossible for the filament to slip.....

Re: Filament slipping

Hi, I've been looking to this issue more carefully and which seemed to be the filament slipping is, in fact, the motor running backwards. Since this print uses linear advance, the pressure created within the hotend, in some prints, pushes the filament backwards and the motor doesn't have anough torq...

Filament slipping

Hello, When printing small holes (fast movements) the filament slips backwards, breaking the extruder calibration. When moving forward, the distance is not enough to compensate the slipped distance and it results in under extrusion. My nozzle is clean (checked) and if I lower the retraction distance...

Re: Outer wall - Cura

Hello

Thank you very much for your help.

It was a mix of over-extrusion and a clogged nozzle. When adjusting the flow and retraction, I set the retraction length a bit high and, possibly, caused the clogg. Nozzle replaced and quality prints are back.

Thank you.

Re: Outer wall - Cura

Hello,

When printing walls with holes for screws I get some problems with the surrounding layers. This was always a problems but, with this print, it's very visible. Does anyone know the best way to correct this issue?

Outer wall - Cura

Hello, I was printing a model and the outer walls came out like the picture attached. https://i.postimg.cc/nMdWzWFH/20190415-203129.jpg I reviewed the layers and the printer movement within cura and the marks on the outer wall were coincident with a printer movement change. I checked, as far as my k...

Re: Over extrusion?

Hello,

Thank you for listening.

Although the cooling system is generally effective, I also believe that, when needed on the back of the printing model, is not as affective.

Rotating this print 90º on the z axis, bringing the overhangs to the front, resulted in a much better print.

Best regards

Re: Over extrusion?

Hello, Thank you for your help. I've tested everything and all is ok with the printer. After some tests, I noticed that the overhang corners warped and that's why the results were so bad and the extruder clicked. Although the fans are working and correctly placed, the printed model, on the back, doe...

The pictures on the following links are from my second try to print de lcd cover. Some parts are great but the lower part of the overhangs i...
