Hi guys.

For about 4 months now im the not so proud owner of a winbo 3d printer (sort of a copy of the makerbot duo).

In the first few days, everything worked fine but than everything went sideways and no matter what i do non of my prints come out right.

When i print, it seems like the filaments just builds up around the nozzle and wont stick to the platform. sometime it does stick, but then the other extruder will just pill it off and make a mess.

Now, i level the print board more than 100 times, i watched every video on youtube about leveling - twice. i tried cheap masking tape on the platform and buildtech, i even tried some stick glue.

Every once in a while it will start a print just fine but than start to make a mess after a few layers.

i have been using only PLA. i tried to use 200c, 210. i tried to heat the platform to 50, 60 ,70 c.

one thing though - when i use a raft thing are much better.

I know its not much to go by, but ill add some photos later today.

Thank you

Tank out.
