I am trying to complete the Mark2 upgrade on a Ultimaker 2. I installed two new Bondtech QR extruders, new printheads and expansion board. I believe I have all the physical parts of the upgrade completed but am now trying to update the firmware. I am running Cura 3.4. As indicated on the Mark2 site I have done the following:
Download the Mark2 firmware from github. Connect you printer via USB. In Cura, select "Manage printers" -> "Upgrade firmware" -> "Upload custom firmware".
However once I locate the file hex file and push update it brings up the updating firmware window, disconnects the printer and sits there. What am I doing wrong?
Also when the printhead tries to home the fan runs into the right side of the printer and tells me the x/y switch is broke.
Any help you can give would be appreciated.
Thank you
