Seeking help to configure the firmware for the UMO I'm in the process of converting to use 1.75mm filament. I've upgraded to the following parts.
1. MK8 METAL EXTRUDER - https://www.banggood.com/3D-Printer-MK8-1_75mm-Remote-Extruder-Metal-Frame-Kit-For-Makerbot-Reprap-p-1070154.html?rmmds=search&cur_warehouse=CN
2. E3D V6 GENUINE NOZZLE - https://www.filastruder.com/collections/e3d-spare-parts-and-accessories/products/e3d-spare-nozzle-v6?variant=755000
Thank you for your reply. I will connect it to pronterface and take a snap shot and post it here. I agree with what you said about making firmware changes for the EStesp, thermistor type and graphic display. Hope to gets some tips once when I post the firmware settings.
