Re: Melzi V2 board on Prusa i3- commissioning - 9 years ago
Hello all, a bit late compared to Richstuch but the baud rate was also the solution for me! When I set it to 115200 it works immediatly. @Enif: I think you are wright, I will try to reflash a new firmware as soon as possible (I realyy would like to know what is behind the control of the printer) but nobody can resists to print his first part before working on that kind of things . Thanks youby Weskrauser - Controllers

Hello, thx for your anwer Enif. Actually I bought my printer from aliexpress (Hesine 3D prusa i3). They are supposed to be plug and play and I do not know what firmware I have. I already asked to the seller and I am waiting for an answer. Baud rate is 250000 in repetier. In fact even after the lights turns off, I am unable to use it with repetier, I have a connexion error when I try to connect (by Weskrauser - Controllers

Hello, I have exactly the same problem. My power supply seems OK (fans can turn if directly plugged to it) but I have the same voltage drop on melzi board when I plug the printer. I can add that I can hear that the PC detects the printer (the windows noise), but impossible to communicate with repetier. Like Richstuch, I will be very grateful if you could provide me some informations on how toby Weskrauser - Controllers
