On this page you will find the instructions for changing amperage on the Funmat HT Enhanced Extruder Motor, via the Drivers.
1. Start by opening the filament chamber on the right side of the machine
2. Remove the 8 screws holding in the panels on the bottom of the chamber
3. Locate the “E-driver” from the 4 drivers in the chamber
4. Use the chart below to change amperage to desired level
We have success around 0.7amps, but if you encounter under-extrusion, consider raising the amps back up. The motor should come from the factory set at 1.6 amps, so adjust the amperage up until the under extrusion ceases.
