OrangeStorm Giga Repair

The Giga lost calibration and dug grooves into the build plates.

Printer: Elegoo OrangeStorm Giga (opens in a new tab)
Problem: Lost calibration; froze during calibration
Fix: Proximity sensor swapped from an older printhead
Status: Complete

01The problem

It would freeze on calibration, preventing me from doing anything with the printer. Fortunately, that was after finishing the big Halloween crocodile (opens in a new tab) print.

02Troubleshooting

Elegoo’s excellent support talked me through testing a variety of things. One suspect was the proximity sensor on the printhead.

03The fix

I had an older printhead with a broken wire that wasn’t working, so I scavenged the sensor from it and swapped it to the current printhead.

Two printheads opened up on a cutting mat, with their orange covers, fans, and small tools around them. — Both printheads opened up

That did it! It’s back in business.
