    Hi I encountered a bug when performing the E3D extrusion mod to my UM2.

    after getting everything installed and doing all the firmware changes, i noticed that now the retraction settings in the printer cap the retraction speed at 20mm/s. even though it automatically sets it to 25 mm/s. if i click and enter the function to change it in the printer, it automatically drops it to 20mm/s and prevents me from setting it any higher

    has anyone else experienced this? I've sent multiple requests to E3D in regards to this and had nothing in response, i find that very upsetting
