firmware bug with E3D UM2 extrusion upgrade

Recommended Posts

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.

just wondering where in the firmware i can find that setting so i can change it?
