Step 10.28 — Set the FAN2 and FAN3 jumpers to 24 V¶
Step 28 of 80 · Chapter 10 — Wiring and Checkpoint #1
Parts:
- two of the jumpers bagged in Ch 09 · already on the bench
Do: Fit a jumper on Fan2 and one on Fan3, both in the 24 V position. Leave Fan0, Fan1 and Probe bare.
Check
Exactly two jumpers on the board, both on the 24 V pins, on Fan2 and Fan3. Count them.
What you're looking at
The jumper block from step 10.3, now being set. A jumper across a port's 24 V pins selects that port's output voltage. The diagram shows the end state: five headers, Fan2 and Fan3 fitted at 24 V, three left bare.
Caution
Rev D+ / LDO: on a Nitehawk build the hotend, part fan and probe all live on the toolboard, so the Leviathan's probe and Fan0/Fan1 ports stay unused — that is why they stay unjumpered. src · BOM
