Re: Heatbreak und Düse in Einem - 8 Jahre zuvor
Das ist doch kein Heatbreak mehr! Der Sinn des Heatbreaks ist es, dass der Übergang von der warmen zur kalten Zone mit möglichst wenig Material (dünnwandig) gefertigt wird. Das sieht mann bei der Version von ganz oben aus VA. Dazu kommt dass das Material an der besagten Stelle möglichst schlecht Wärme leiten sollte. (VA beim Original) Deswegen auch der Name: Heat- Break, der Wärmefluss vom Hotevon Yellobello - Extruder, Hotends & verschiedene Materialien
Re: MarkForged Kinematics vs Hbot vs CoreXY - 8 Jahre zuvor
Quotebrazenrain Wait a second, the MarkForged's config still requires both motors to move purely in Y Off course, but the "X" motor only turns to clear space to allow the Y movement to happen. I don´t like the design either. woo already said enough. the prototype has very expensive linear rails to compensate for this "off centric" momentum - ladden movements.von Yellobello - General New Machines Topics

DRV8825 Vref question - 9 Jahre zuvor
Hi! I am having trouble with my 8825´s because I can´t get them to work properly with my stepper motors. I have 5 clones and 1 original one with the Vref on the via. Before I checked the voltage, I found out that by trimming the motors, there is only a very thin slice on the pot dial which makes my motor working instead of ticking loud. So, I decided to use my multimeter and see whats going onvon Yellobello - Stepper Motors, Servo Motors, DC Motors
Re: AMIS-30543 drivers 
- 9 Jahre zuvor
Hi! Any news on this topic? I find it quite interesting what the drivers are capable of. I just ordered one to play around. Also the AZSMZ board is OS now. The AZSMZ is a very simple design / ripp-off of the smoothie-board...I think I would be able to design a modified version of the board with AMIS-30543, however I would not be able to write the code nor modify the smoothie ware.von Yellobello - Next Wave Electronics Working Group

Re: Wobbling - 9 Jahre zuvor
So, reducing the Amax together with loosening a little belt tension helped to get rid of most of my "dents" . However from time to time another dent occurs during huge prints. It could well be that my Y-belt might be grinding on the pulley. Need to fix this as well. Thanks for the help!von Yellobello - Prusa i3 and variants
Marlin DEFAULT_ACCELERATION vs. DEFAULT_MAX_ACCELERATION - 9 Jahre zuvor
Hallo! Ich verstehe gerade nicht wirklich warum es DEFAULT_ACCELERATION und DEFAULT_MAX_ACCELERATION gibt. In meiner Logik ist es doch ziemlich unnötig ein maximum anzugeben, wenn es eine standard-Einstellung gibt die sowieso immer genommen wird. Oder gibt es Fälle, in denen DEFAULT_ACCELERATION überschritten werden kann?von Yellobello - Software

Re: Wobbling - 9 Jahre zuvor
Hi! I just checked my Z-rods which are Tr8x8 and they are perfectly straight (rolled them over a flat surface). I also checked my acceleration of x and y and they were 5000 mm/s^2 which was the marlin standard setting. Lowered it to 2000 and uploaded the firmware again. When I have the whole thing assembled again I will update. Thanks so far!!von Yellobello - Prusa i3 and variants
Re: Skipping Steps in only one direction, Help pls - 9 Jahre zuvor
This can come from two issues: 1: Check if your corresponding axis has some resistance (mechanical) 2: Check if your stepper driver is calibrated correctly, either the stepper motor does not get enough current to drive the axis or the stepper driver overheats. do you cool your drivers?von Yellobello - Prusa i3 and variants
Wobbling - 9 Jahre zuvor
Hi! I have an acrylic frame i3 which I finished* today. The prints come out quite good, except one little thing: This looks wobbly, I know. But since this misalignment only occurs in Y-direction, I guess this is Y-wobbling?? ( I only knew z-wobbling until today, which looks different.) take a look at the other side: This looks way better!

Re: DIY Tiny OLED I2C full graphics controller - 9 Jahre zuvor
Quoten.glasson As Enif has noted earlier, the side facing encoder has an illogical response depending on if you are scrolling menus or changing numeric values. If you set the encoder rotation in firmware to suit the menus (rolling the thumbwheel downwards at the front to scroll downwards), then when you reach a screen where you change a numeric value the same downwards rotation increases the nuvon Yellobello - Controllers

Re: RAMPS for BeagleBone - 9 Jahre zuvor
Hey Charles, I like your work and I´d love to use your CRAMPs board, but the problem is known: It´s unavailable :-) So, I read about the option of using the RAMPS-FD board and directly wire it to the BBB. What do you think about this?

Hi, I have a hard time wiring the SPI display up... no datasheet for the sainsmart display seems to be available. The connectors are called CS,RST,DC,SCLK,SDIN,GND and 3,3V. SCLK is the clearest one and does not need any explanation, SDIN seems to be MOSI, CS seems to be SS. However, I have no clue what RST (Reset ? what does that have to do with SPI?) and DC are.

Re: General AZSMZ mini board topic - 9 Jahre zuvor
I contacted the creator of the board and asked why he did not put the board under a proper OS license.

He said that by releasing the schematics that would be suficient for studying the design.
