Hi, I have just upgraded my Geeetech Prusa Pro B i3 upgrade to E3D V6 + Titan combo which i purchased ready built designed for the printer. I have install and updated the firmware as described in the documentation but I can’t get the Titan to extrude, the V6 heats up well and I can manually push/extrude filament but a can’t see the motor doing anything. The motor came ready installed but I am thinking it may not be getting enough power? Has anyone had similar issues or can help? The main board is a gt2560 + do I need to do anything with the driver for the motor? I was thinking of swapping the motor of the one on my old mk8 to see if this helps but not certain how it will work with the Titan. Thanks
