|
## 10. PRE-POWER-ON VERIFICATION
|
|
|
|
### Visual Inspection
|
|
- [ ] No exposed wire strands touching other terminals
|
|
- [ ] All screw terminals tight
|
|
- [ ] No pinched wires
|
|
- [ ] Polarity correct on all power connections
|
|
|
|
### Multimeter Checks
|
|
- [ ] No short between 24V+ and GND on Octopus
|
|
- [ ] No short between V+ and V- on any DM542T
|
|
- [ ] Continuity on all signal wires (disconnected from board)
|
|
|
|

|
|
|
|
## 11. FIRST POWER-ON SEQUENCE
|
|
|
|
### Step 1: Octopus Pro Only (no motor power)
|
|
- [ ] Connect USB to Pi
|
|
- [ ] Power on 24V supply to Octopus
|
|
- [ ] Octopus LEDs illuminate
|
|
- [ ] No smoke or burning smell
|
|
- [ ] Run `ls /dev/serial/by-id/*` on Pi - device appears
|
|
|
|
### Step 2: Flash Klipper Firmware
|
|
- [ ] Build Klipper for STM32F446
|
|
- [ ] Copy firmware.bin to SD card
|
|
- [ ] Flash Octopus Pro
|
|
- [ ] Verify serial device still present
|
|
|
|
### Step 3: Start Klipper
|
|
- [ ] Copy printer.cfg and macros.cfg to Pi
|
|
- [ ] Update serial port in printer.cfg
|
|
- [ ] Start/restart Klipper
|
|
- [ ] No errors in Klipper log
|
|
- [ ] Fluidd connects successfully
|
|
|
|
### Step 4: Test Without Motor Power
|
|
- [ ] `QUERY_ENDSTOPS` - all show correct state
|
|
- [ ] Temperature readings appear (room temp)
|
|
- [ ] No heater errors
|
|
|
|
### Step 5: Motor Power On
|
|
- [ ] Power on DM542T power supply
|
|
- [ ] All DM542T LEDs illuminate
|
|
- [ ] Test single axis movement at low speed
|
|
- [ ] Verify direction (invert DIR pin if wrong)
|
|
|
|
### Step 6: Full System Test
|
|
- [ ] All axes move correctly
|
|
- [ ] Both extruders work
|
|
- [ ] Homing works on all axes
|
|
- [ ] IDEX tool change (T0/T1) works
|
|
- [ ] Heaters respond (test at low temp first)
|
|
- [ ] Fans operate
