Error stopped - Temp sensor bed

Recommended Posts

Hi

Tonight after a few weeks without any printing I switched from PLA back to ABS.

I then heated up the bed and initiated a new print. Once the bed and nozzle were at the right temp, the bed was raised to start printing.

But that's when things went wrong. As the bed was moving up it sounded like a missed step and I was instantly graced with a "Temp sensor bed" error.

I power cycled the printer and the print sensor seems to work and give credible figures.

Here's a video of the bed being raised and lowered. At 00:35 the weird sound can be heard (and again the printer goes in error mode). Surprisingly I've been able to lower/raise the bed a few times without problems. But most attempts (usually raising) fail with that weird noise.

 

Note: buzzing at 00:15 is unrelated to the printer . I just got a text on my smartphone...

Cables going to the bed seem fine and are out of the way when bed is travelling up or down.

Any idea where to look ?

Thanks

I've come to think that it might indeed be a simple connection issue. I've wiggled the cable on the bed end and have been able to move the bed up/down multiple times and run a 1-hour print.

The brief connection issue causes the printer to go into error mode. Maybe that brutal change somehow interrupts the code running the stepper motors for a few cycles hence what sounds like a missed step ?

Anyway I'll try check the cable tonight a bit more carefully.

Good to have the build manual. Thanks.

Hi All,

I've got the same error with after the SAME weird sound (at 00:35 in your video)

I've check the wire, the connector and every things OK but my Ultimaker say "ERROR STOP - Temp sensor Bed"

Can you help me ?

Thanks
