Hello, i´m from spain. Sorry for a possible poor or bad english.
Recently i buy a kit of the printer k8400 with one extruder. I mount the printer and work perfect some days, suddenly the y-axis don´t work good. Sometimes the y-axis is locked and moves slower and not ending movement orders which should, modifying the printed image. creating a lack of control on the y-axis does what he wants
Is engine problem? because the belts are not touching movement and not rub against anything
Thanks, I have this problem for almost a month already. send a message to the technical service / commercial department and I respond now post it here
He intentado hacer el pequeño molde que sale en la pagina Wiki que me habeis mandado y sale asi
I tried doing the little mold that appears in the Wiki page that you have sent me off so (translate by google)
good morning , possibly I have not explained well . the image is causing the piece to print . Part of calibration
the problem is that the x axis does well its route . I want to know if it is possible for the engine to be wrong or settings.
It takes more than one month and purchased even I have not been able to use . the biggest problem is that I have since the arm well . first because it sends an e- mail to contact the website and did not answer me . second because I’ve done what I’m told and still not working. another brand had thought before buying 3d printer but k8400 buy the recommendation of some engineers and friends but I think it might be luck that touched me so many recommendations after bad printer, because the price difference between one brand and another It is considerable and I 'm still waiting to help me
buenos dias, posiblemente yo no me he explicado bien. la imagen es lo que provoca al imprimir la pieza. la pieza de calibracion
el problema es que el eje x no hace bien su recorrido. quiero saber si es posible por estar mal el motor o por ajustes.
lleva mas de un mes comprada y aun no la he podido usar. el mayor problema es que llevo desde que la arme asi. primero porque mande un correo a los correos de contacto de la pagina web y no me respondieron. segundo porque he realizado lo que me dicen y sigue sin funcionar. tenia otra marca pensada antes de comprar la impresora 3d pero compre la k8400 por recomendacion de unos ingenieros y amigos pero yo creo que puede ser suerte que me haya tocado una impresora mala despues de tantas recomendaciones, porque la diferencia de precio entre una marca y otra es bastante considerable y sigo esperando que me ayuden
OK first thing first, you need to align the X and Y axis. You can find the procedure on the [color=#408040]Wiki[/color].
Once correctly tune this printer works like a charm.
[color=#0080BF]Mr. Raby .
We saw that the problem was constant, we returned to dismantle the shafts. And we turned to follow the assembly instructions . Building it with manual measurements .
The problem persists
We have looked to measures with a caliper and are all perfect[/color]
Other solution?
[color=#BFBF40]Señor Raby.
Nosotros al ver que el problema era constante, hemos vuelto a desmontar los ejes. Y nosotros hemos vuelto a seguir el manual de montaje. Construyendolo con las medidas del manual.
El problema persiste
Nosotros hemos mirado con las medidas con un calibre y estan todas perfectas[/color]
¿Otra solución?
You have to do it following the Wiki not the manual. The measures are not correct.
Tienes que hacerlo siguiendo la Wiki no el manual. Las medidas no son correctas.
[color=#0040FF]this afternoon I’m going to do a video for you to see exactly what happens
I translate if anyone knows to fix in Spanish[/color]
[color=#8040BF]esta tarde yo voy a hacer un video para que vosotros veais exacto lo que ocurre
lo traduzco por si alguien sabe solucionarlo en español[/color]
Just take a hamer and knock those XY LINEAR BEARING CLAMP outwards untill it runs smooth… Just as simple as that… The numbers in the manual are TOO SHORT! Besides if you read the manual correctly it says “The distance should measure about 32,8cm. Slide the pieces back or forth until the distance is correct.” This means its NOT exactly but around/(about) 32,8cm make it more like 33,2cm… You just need to hammer tap it until it fits perfectly…
Raby’s wiki explains it perfectly and saved me a BUTTLOAD of time!
So once again thank you Raby.
Using a hammer to fine tune some plastic pieces imo is a bad idea Don’t get me wrong “raby” .) . Very good manual, too bad I seen it after going through my own “hammer time” with those axles.
Some people might use the wrong amount of force and break something.
I used the back of a screwdrive and I can’t stress enough to used VERY LITTLE FORCE. Remember the case is PLASTIC. A small tap is enough as “jeafke” says in his post. Imagine hitting your finger with it with enough force to feel it but not hurt .)
Definitely an axis misalignment. Tune your printer as explained in the [color=#408040]Wiki[/color]. (Si no lo entiendes en Ingles, Google translator te lo traducirá bastante bien o me puedes mandar un mensaje). You shouldn’t heat the head with the top fan not mounted (you’ll burn the PEEK tube).
And it looks like that the glass plate is upside down with the glass part on top and the Buildtak under???
LOL are you printing on the glass side of the buildplate? Or why is it that reflective… Dude losen up those pulleys, move the head by hand untill it runs smoothly by hand. One axle a time, this should get you a kinda running machine which you can print the align guides with. Just first get the damn thing running smoothly by hand first before making me have goosebumbs with that nasty rattle… And OIL THOSE RODS!
Looking again: The small belt of the stepper on the far right of the video is WAY to lose imho… Pull it a little down and angle the thing a little so it gets pulled to the reverse side of where the long belt runs.
It seems the buildtak sheet is not applied to the sheet of glass. You can remove the white backing of the sheet and it will reveal an adhesive so you can stick it to the glass surface.
Don’t get me wrong “raby” .) . Very good manual, too bad I seen it after going through my own “hammer time” with those axles.
