Second layer adhesion

[gbeeton]

I’m having trouble getting the second layer to adhere to the first layer using the dual extruder module.

Any help would be welcome.

That looks like severe underextrusion - I guess you need to calibrate your E-Steps.

Sure enough it was underextruding by 31%! After Calibration it looks much, much better.

Thanks for sharing you expertise!
