[UM2: Brim adheres but first layer doesn't]

Hi,

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

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!

[UM2: Brim adheres but first layer doesn't]

Hello,

I had been using UM2 without issue for a few months.

However a problem has developed where:

 

1. The Brim always prints really nicely and adheres to the plate very well (actually it is hard to remove);
   
2. 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?
