Issue with Tough PLA binding up after Firmware update

[jfrench3000 0]

Since running Firmware update our Tough PLA is binding up in Bowden feed. I have ran Hot/Cold pull and still having issue.

What do you mean with "binding up" ?

The tough PLA is getting stuck and the wheel that feeds PLA is just spinning, causing a half moon wear mark in PLA

My first idea is/was that your print core is clogged, but you have already checked that with hot/cold pulls. Another idea is that your front fan is blocked by some debris or not working at all. Check if the fan in the middle of the print head is working when you start your print job. The fan starts automatically when the print core heats up. This fan is needed to cool the upper part of the print core.

 

Another possibility is that your feeder tension is too high, the marker should be in the middle position. 

Or the feeder is dirty or blocked.

 

Check also the Bowden tube if you see any debris.

 

And software wise, it could be that you print too fast or too cold.

Print core is clean, front fan is fully operating, feeder tensioner is in middle position. Print temp is 200 C and speed is 70mm/s. If any other suggestions ill advise.

 

Thank you
