Hello onek, At last someone interested in the idea ! LOL That is exactly what I was talking about. I think it is a good idea to make something anyone can do only by purchasing some ready and easily purchased boards like arduino nano and uno, some cheap components and a master board that they can possibly make with DIY style (copper etching...etc.) . I guess it is worth the effort. I recently maby xdarko - Experimental and Hobby
Thanks! I will wire all X,Y,Z to UART mode that should be most efficient. As for the extruder I will use standalone OTP mode for spreadcycle enabling and get most of torque and velocity.by xdarko - Controllers
Thank you for clarifying this I've read the there's a downside in using software serial which is you cannot use multiple pins in the same instant. Does this affect negatively on the performance of 3D printing? There is another library called AltSoftSerial which tackles this problem. did anybody use it for simultaneous serial communication? What about unconnected pins if I use the UART communicby xdarko - Controllers
Greetings everyone, I am working on a new board layout similar to RUMBA but with integrated TMC2208. I am looking for a schematic that includes UART mode connections between the drivers and the atmega2560 IC. I stumbled on some articles considering this matter in a different way which is converting from the standard legacy mode to UART mode but I didn't help but notice when I looked into pin aby xdarko - Controllers
Hello guys! I decided to start a board project to learn more about board designing and was like, why would I start schematics from scratch if I have this big database on the internet providing me with so many board schematics and boards? Especially if am doing a board for a very common FDM printer design and nothing is special. A RAMPS can operate it just fine I just want it to be a single boarby xdarko - Experimental and Hobby
For the moment my primary concern is with firmware. Let's say that I have the necessary communication pins do you think that I can modify the Prusa Firmware in order to adapt it to my machine?by xdarko - Firmware - Marlin
Hi guys, Am very interested in the MMU 2.0 and willing to buy the kit soon. Only that I heard Josef Prusa saying that the kit is only compatible with Einsy board and Prusa i3 MK versions. Honestly I don't think that is impossible to connect the MMU board to another one like in my case a Makerbase board (MKS Gen 1.4) . Can you discuss the proper approach to connect any different board and printeby xdarko - Firmware - Marlin

So my printer was working just fine for maybe like 5 months with the board functioning perfectly. And recently it begun interrupting the print over and over again. After a few times of this, a part labeled S1G blew up. I think it was an overcurrent because my wiring was wrong as I only used one pair of screw terminals to draw in 12V for everything. So the screw terminal melted and the component bby xdarko - Prusa i3 and variants
Hi everybody, So I am working on a convoyer type XY core 3D printer that uses a Kapton covered belt ( Board: MKS Gen 1.4 based on ATmega 2560) . I need a way to modify the firmware in order to make it possible to print all the G-Codes loaded into the SD card. In other words, after finishing the read and execute process of a file (G-Code), it automatically goes to the next file and does the sameby xdarko - Firmware - Marlin
Hi everybody, So I am working on a convoyer type XY core 3D printer that uses a Kapton covered belt (MKS Gen 1.4 based on ATmega 2560) . I need a way to modify the firmware which is in my case "Marlin" in order to make it possible for me to print all the 3D files (which are converted into G-Codes individually) loaded in the SD card.

Quotemso797 Hey Guys, For the past year and a half, I have been working on a 3D printer that can automatically eject prints. Here is a quick demo of the printer. https://youtu.be/E_RvnqVHbnA I also configured the machine for infinite build purposes. I realize that their are a lot of technical issues that need to be ironed out But I think it's a cool design worth exploring. My goal is to fulby xdarko - General

Hello everybody! I am very confused with my problem so i would be most thankful if anybody would help me as soon as possible so thanks in advance! I just finished assembling a Prusa i3 rework, electronics: RAMPS 1.4+NEMA 17+NEMA 14(Z AXIS)..., Firmware: Marlin 1.6.6 with an a geared extruder just like in the photo attached . So it works just fine (had some calibrations first and had a little pby xdarko - Reprappers
Hi everybody! I am building a PRUSA i3 printer and am printing parts on the basis of making a box style frame out of MDF wood by a laser cutter but now...am considering to switch to aluminium profiles as an alternative way to simplify work (less cutting...) SO my question is...DO I NEED to print parts specially made for the single sheet style and purchase other hardwares (bolts,screws,nuts...) orby xdarko - Mechanics
According to reprap.org under the title "Choosing a Power Supply for your Reprap project" its written : "5 stepper motors, each run at up to 1.2A @ 4V peak per phase = 5 * 4 * 1.2 = 24W, times 2 to allow (conservatively) for driver losses and back emf during movement = 48W" So my main question is why multiplying by 2? why not 1.5 or maybe 3? is there a certain standard used here or what?by xdarko - General
