Nocolinux, I will check it this afternoon. BTW, I was happy with this new feature, because sometimes there was no filament in the nozzle at the beginning of the printing. More later....

Lo de los ajustes que comentas, no sé si yo si será necesarios. Cuando el principal problema es a qué temperatura imprimir, a qué velocidad, que cuando cambias de fabricante, e incluso sin cambiar de fabricante cambias de color.... todo se puede desasjustar y tienes que volver a encontrar los ajustes óptimos. En cuanto encuentras los mejores parámetros, la UM2 es una máquina de muy buena precisión. Supongo que en extrusión de plástico ahora no hay nada mejor, como mucho igual. Todo esto de la impresión 3d es muy experimental. Pero como hobby es muy divertido. Dentro de unos años imprimiremos con máquinas láser y nos dará vergüenza haber pagado esta fortuna. Pero por ahora es lo que hay.

I really appreciate this video. T H A N K S !!

Thanks! I am looking for a good solution for no spooled Faberdashery filament. The solution to leave it on the ground it does not work for me. Any suggestion?

After playing with temperatures, flow ratios, first layer speed, first layer thicness... now I obtain a perfect first layer... absolutely perfect! do you know how? It does not matter the temp, flow ratio, speed...... it only needs a perfect bed levelling. this is my experience.

A summary: 1.- I am FED UP of levelling the bed before each print. Really fed up...in Spanish... hasta los huevos. 2.- I have tried raising and lowering the bed before the calibration and before printing... and it does not work. 3.- It is a too expensive printer to be levelled each time. 4.- I really want a solution. 5.- Thanks people who is trying to solve this issue

we need a video!!!! Everybody is asking and asking... please post a video...

Hi friend... A twitter follower from Spain...

yes, a video dismantling the nozzle would be great... I do not want to damage my new UM2

I think you have to check the other side: the visible one. If this side is OK... However, it seems you have a low temp or underextrusion or a bad levelled bed... anyway, check the other side...

I think the cost of resin is huge

Are MK7 or MK8 drive gears a direct replacement? Or do I need to make some adjustments to avoid under / over extrusion? Thanks.

What do you think? Print with Robert's feeder at 230, pink from colorfabb It seems some problems at 10 mm3/s

Amazing

thanks for sharing! and how much time to shift color?

I cannot believe that...

Thanks Gr5 for finding the origin of the problems. Some of us are using free CAD software where we cannot manipulate that settings, tinkercad in my case. So I am worried about future versions of Cura having the same issue and with no possible solution.

Thanks for your interest. Mail sent. Follows a picture of both parts: Cra 14.01 left, cura 14.03 right. we can see a "bumpy" corner on the right. An the noozle follows that artifact very slowly, incrreasing printing time. I have found in many parts that 14.03 produces worse prints and takes quite a lor of more time to print it.

it is amazing... even printing just a box with rounded corners... comparison 14.01 and 14.03... 14.01, when printing the outer shell, just it prints it smoothly. 14.03... in the round corners tr takes more time drawing the corner and producing some artefacts in the corner...ç this is just a rectangle with round corners!!!... please.. solve that BIG ISSUE

dual extrusion...dual problems? :???:

the filament makers should give more advises...

so...is it finally working on UM2?

Tinkercad seems a stupid CAD software for children.... at the beginning... then you realize later that some functions are there... and that with the help of the shape generators developed by the community you can do more advanced pieces... finally... you get used to do everything with the mouse... and finally... you love it.

But you still have the original feeder... Anyway, I was considering to print one spool holder for the floor...I am buying loose filament and a holder it is required. So an universal spool holder for the floor may be a good solution. You can find some designs in youmagine, thingverse...

Could you please post a picture of where is the spool now?
