Hi, An update - after leveling and playing around with settings several times, managed to get it working by setting initial layer to 10mm/s Regards,

Hi prb4, Thank you for your post and advice. I have the first layer set to 0.3mm. I also tried setting it to 0.4mm but it didn't make a difference. I tried leveling a few times - using a sheet of paper as the calibration card has been lost. Would you suggest getting the bed leveled closer still? I will try the "Leveling Rings" gcode when I get back to the office where the printer is. Thanks for the link! Regards,

Hello, I had been using UM2 without issue for a few months. However a problem has developed where: The Brim always prints really nicely and adheres to the plate very well (actually it is hard to remove); But the first layer does not adhere to the plate. Instead it then accumulates onto the hot end as the extruder passes back over the material. So all I get are blobs of plastic mess where the actual layers are meant to be. I always clean the plate and apply the glue stick before a print. I have re-leveled the bed. I am at a loss as how to get this machine to print anything now. Any advice or help?
