Universal Controller Electronics Test Protocol
From Open Source Ecology
- Power supply wired, USB power supply, power to Arduino with RAMPS, LCD connected - LCD posts with correct machine name
- Plug in 3 endstops
- Plug in power supply plug assembly and connect to power supply
- Run signal wire to SSR, andFeed 5V from RAMPS to that signal line
- Plug in 2 thermistors
- Connect power supply to RAMPS, and feed the fan into the same power terminal
- Connect blower
- Connect extruder heater
- Plug in 5 motors and test Prepare-> Auto Home. The pattern you will observe is X moving until endstop triggered, Y moving until endstop triggered, and Z moving until height sensor triggered. If not triggered, it times out and moves until next step. Note X and Y move fast, Z moves slower. Test pass is when there is solid, continuous motion. Draw a line on the end of motor shaft to see motion clearly, as the shiny shaft does not look like it's spinning.
- To test extruder motor, plug motor into X axis to test motor only. This doesn't test the extruder driver.
- To test extruder driver, one way to do it is by wiring up the heater block and getting it up to temperature, and Move->Axis->Extruder by 1 mm in the LCD menu. Or, go into Cura and disable low temp lockout on extruder motor - M302 to enable cold extrusion, then run the Extruder through Cura.
