Problem with 1st layer calibration

Hi,

 I am hoping someone will know why my printer has started to do this.(see photo)

I had an issue with some jammed filament, which I sorted out, recalibrated and then started printing again, then all of a sudden, mid way through a print the nozzle lifted to 10cm off the bed and stopped extruding, 

So I recalibrated the Pinda with the zip tie, then went through the calibration wizard, and it was all fine and reset.

NNowthough when I print the 1st layer calibration it does what is in the photo.

Anyone got an idea why?

Regards.

Give the print-sheet a really thorough clean, dishwashing detergent and HOT water; then try again.

Cheerio,

RE: Problem with 1st layer calibration

Hi Guys, I an experiencing exactly the same problem except my nozzle only lifted about 1 mm off the surface. The end result looks exactly like your photo. HELP?

Please run a first layer Z calibration and show us the result *on the print sheet*

Cheerio,
