Parts coming away from the bed

So having issues with parts coming away from the bed on the sides.

think maybe the environment I'm printing in might be the issue, in a outbuilding/gym that's around 8c here in the UK.

note : I have to warm the machine up with a fan heater to remove the min error temp before I'm able to use the preheat function.

Printing in PLA using the default settings, calibrated Z level with 75x75 square.

PLA doesn't usually need an enclosure. You can improvise a temporary one to test whether it helps by putting a large cardboard box over the printer.  It is more likely to be caused by drafts than ambient temperature so a simple screen, or just being careful to shut doors/windows might be enough.

Cheerio,

forgot to mention, the bed is cleaned with the soap and water technique.

I was doing some tests so had 4 of these each in one corner of a mk3s bed so maybe because its moving between layers to each part the cold environment is causing issues because if I print just one part and the printer is concentrating on this then I don't get the issue,

Cheerio,

I think you're right about the enclosure, currently its in one but with the door open due to being PLA, I guess with the dramatic drop in  temperatures I need to account for this and close the door and try to keep a higher ambient temperature.

Thanks for taking the time to respond to my issue.

update: controlled the enclosure by closing the door and increased the ambient temperature seems to have solved the issue, thanks for the help

RE: Parts coming away from the bed

Also your other post saying you have under extrusion, well it looks like your z could do with coming down a touch.  That will also greatly effect how well parts stick to the bed.

Fix 2 things with one adjustment.
