3D Printing - G-code Fundamentals

You see this G-code line causing a print error:
M104 S-10
What is the problem and how to fix it?

ATemperature cannot be negative; change S-10 to a positive value like S210

BM104 cannot be used for temperature; replace with G1 command

CThe command is missing a wait; add M109 before M104

DS-10 means wait 10 seconds; replace with S10 to fix

Step-by-Step Solution

Solution:

Step 1: Identify invalid temperature value
Temperature values must be positive. S-10 is invalid because temperature cannot be negative.
Step 2: Correct the temperature value
Change S-10 to a valid positive temperature like S210 to fix the error.
Final Answer:
Temperature cannot be negative; change S-10 to a positive value like S210 -> Option A
Quick Check:
Temperature must be positive = fix S-10 to S210 [OK]

Quick Trick: Temperature values must be positive numbers [OK]
