I have flashed blink, then the test code, then blink again, in some variations. If blink is flashed, the LED blinks. If another code is flashed, it blinks not or in another interval. We have working led test cycle when test code is flahed, and we can only connect to pronterface (but are able to connect, we have the right measurements for temps), if marlin is flashed. This proves that flashing anvon Bonscha - Reprappers
I have tested the electronics like we did last night, and have photographed and noted the setup and results. First of all, here is a pic showing our motor connector. It has been shipped that way, so I assume on motor side, the connection is okay. Also you can see the circuit diagram of the motor. How are we supposed to connect the motor to the board? I mean, which color on which pin? motor_diagrvon Bonscha - Reprappers
We have tried to troubleshoot the whole thing today. It has taken us from 6 pm to 1 am and we didn't get it working, but we have acquired some potentially helpful information. First, we have had a board with no jumpers preinstaled whatsoever. The faulty board had all jumpers set under the drivers, also the jumper next to the reset button. Second, we had trouble connecting the whole electronicsvon Bonscha - Reprappers
I just flahed the following test code and tried again in the shown setup (x-axis driver and motor only): #define X_STEP_PIN 54 #define X_DIR_PIN 55 #define X_ENABLE_PIN 38 #define X_MIN_PIN 3 #define X_MAX_PIN 2 void setup() { pinMode(X_STEP_PIN , OUTPUT); pinMode(X_DIR_PIN , OUTPUT); pinMode(X_ENABLE_PIN , OUTPUT); digitalWrite(X_ENAvon Bonscha - Reprappers
Here's a video, maybe you see if we do something wrong.von Bonscha - Reprappers
Didn't help, either... blinking like a fire truck, but no movement of the motor... I will post a video so you can look for possibnle mistakes I make while connecting etc... How can we troubleshoot if drivers or motors are faulty? (Tried on 2 motors and both didn't work).von Bonscha - Reprappers
Hello again. The second ATmega2560 came today, and we tried again! ATmega2560 is okay, connects via USB and is flashable. I connected it, waited for the drivers to install, then flashed it (using the most recent arduino software) with the RAMPSTestCode.pde. We have two RAMPS1.4 shields. One of it has a missing LED (the corner red one), which is why we have gotten a free second one. We mountedvon Bonscha - Reprappers
We had a not-so-well made plug which did wiggle a lot, so yeah, probably the motor has disconnected while powered.von Bonscha - Reprappers
It does not connect via USB anymore. I cannot flash another bootloader because it doesn't get recognized, also doesn't show any indication that it is working.von Bonscha - Reprappers
So it really should work just connecting a single motor to the boards and run this with flashed test code? Well, we fried the atmega2560 (doesn't connect anymore via USB ), the new one will be there in 2 days. On the plus side, we seem to have one excess driver and two RAMPS boards, so chances are we have backup when needed.von Bonscha - Reprappers
Hi, what do you mean with "power down"? Unplug the PSU connector? Can you give me a step by step how to check with a single motor if everything is working?von Bonscha - Reprappers
Hello, we just tried to test if the electronics and motors are working. We own the kit from banggood with an atmega2560 with RAMPS1.4 and the motor drivers, attached all of that and connected it to our computer. After installing the official driver, we were able to flash the marlin firmware without problems. Connection to pronterface seemed to work. We connected our PSU and one motor and nothinvon Bonscha - Reprappers
Hallo, gibt es jemanden, der uns ein komplettes Set für den Prusa i3 und den Extruder drucken kann? Eventuell noch eine Adapterplatte für den Extruder... Wenn möglich in schwarzem ABS. Würde mich freuen, wenn jemand Kontakt diesbezüglich aufnimmt. Genaue Teile suche ich dann gern heraus bzw. liefere die Dateien. Im Voraus vielen Dank!von Bonscha - Schwarzes Brett
So we will tackle this project as a team, 2 of us will do the metalwork on the frame and small parts while waiting for the electronics from China, and then we will try to assemble it when all three of us are together for christmas... We will build a Prusa i3 sheet variant. Nice-looking and seemingly easy to build and maintain. I have seen full build instructions on Youtube, which was very helpfuvon Bonscha - Reprappers
Hello Schufco, maybe you had the chance to take a quick look at the links to banggood. Waiting time and ordering in China are no problems for me. What interests me is if those parts are actually useable or if they are just cheap junk. In which case, obviously, I wouldn't order them. If anyone can confirm the quality of those items is okay, or give me a quick glance at possible downsides, that wouvon Bonscha - Reprappers
Hello, I just found out about budget builds of 3d printers and all this stuff. Before knowing there is a large community taking on diy 3d printer projects, I thought that you'd have to have lots of money for buying such a device. Now I really consider building a reprap, but I'm not sure which model, which components to use and for which things to look. I don't expect you to give me all info Ivon Bonscha - Reprappers
