You should download a firmware. Edit and compile on computer, then onnect the board and computer, and burn it into the board.

Hi
Please leave your email address,
I'll send you one which we are using.

[buzmal]

hi please forward it to gmbuzmal@gmail.com

I have received the file but there doesn't appear to be a file i can open with ardunio to edit, it tells me i can only open .ino or .pde files and everything in the zip is .cpp or .h, some guidance is needed....

[buzmal]

hi thanks for the reply via email, the only thing i need to work out now is the z axis endstop positioning, but i will post again if any further hel is needed

[harry_chen]

Glad to hear that, good luck!

so i have got all the axis working and if i run the system the printer moves as it should, however the extruder isn't functioning correctly, I am using 3mm filament, and the video https://www.youtube.com/watch?v=EpHmXHF ... e=youtu.be will illustrate what is happening, if i loosen the top screw the motor will spin freely what can i do to fix this issues.

What is the filament you use and the nozzle's temprature?
Is the problem similiar to yours?
