Given the following G-code snippet:

M104 S200
M140 S60
M190 S60
M109 S200

What does this sequence do?

ASets bed to 200°C and nozzle to 60°C, waits for nozzle then bed

BHomes the printer and starts cooling fans

CSets nozzle to 200°C and bed to 60°C, waits for bed then nozzle to reach temp

DStarts printing immediately without heating

Step-by-Step Solution

Solution:

Step 1: Understand each G-code command
M104 S200 sets nozzle temp to 200°C without waiting; M140 S60 sets bed temp to 60°C without waiting; M190 S60 waits for bed to reach 60°C; M109 S200 waits for nozzle to reach 200°C.
Step 2: Interpret sequence behavior
The printer sets temps, waits for bed temp, then waits for nozzle temp before continuing.
Final Answer:
Sets nozzle to 200°C and bed to 60°C, waits for bed then nozzle to reach temp -> Option C
Quick Check:
M104/M140 set temps; M190/M109 wait for temps [OK]

Quick Trick: M190/M109 wait for bed/nozzle temps before printing [OK]
