The extruder stop working in print, in manual control with the lcd and by software control.
Try with temperature at 200c. Swap the motors drivers, and motors,everything is ok.
I measure the voltage at motor driver and everything is ok. I reload the firmware and have the same problem. It seems to be a recurrent problem as I can read in the forum.

I swapt the control board with a ramps 1.4 and the extruder is working now.
I notice on my GT2560 board there's a capacitor that had been manualy solder in serie with another capacitor. That capacitor is not on the original pic of the board on your website.
Is that capacitor for correcting a problem of design of the board ?
Who should I contact for a replacement part ?

Thanks

Hi, that capacitor is necessary, but we've improved the board.
Is the extruder motor moving without filament?

It moves now with the ramps 1.4 board. I did all the tests for 2 days and swapping boards was the last option and it confirm the the gt2560 was faulty.

Please contact the customer service.
