gt2560 neither extruder ports working
Hi there I have a geeetech prusa i3 pro B (or chinese copy) I was printing O.K until I turned up the pot on the extruder driver, I think I adjusted the Z axis end stop too low and the extruder couldnt get the filament out, but with the pot so high I think it stalled it. Now extruder wont turn or move,, I have swapped the plug to X axis and the extruder turns when x axis moved. I swapped the control boards with X axis still wont extrude. I have swapped to extruder port 2 with known working board but it still wont extrude..!!! Any help would be greatly apreciated…STU

You mean you plug the driver a4988 of x motor to extruder1 socket and extruder1 socket still doesn't work by " I swapped the control boards with X axis still wont extrude."?
If so,i'm afraid the socket has no output signal...

yes a swapped the driver board from a known working socket, but i also swapped the sockets to extruder 2 in the firmware and still didnt get any output from that socket either? i have proven motor, cable, and motor driver ...
