Hey all, my first post on here so please be kind, and I'll try not to waste your time!
I'm using the rev 3 ultimaker.
I started with ABS, and have moved on to PLA and I'm having some issues with printing the first layer of this 4-sided pyramid.
There seems to be quite a lot of lumps and blobs and so on and whatever I try doesn't seem to get rid of it. It seems like there's too much material squirting through the nozzle.
I've tried tweaking the temperature (190, 205, 210, 220). 190 doesn't print so well and the material stops extruding about halfway through the first layer. The others seem to be blobbing - 220 a little more so.
I'm printing at 60mm/sec.
I've change the E-steps around a bit to no effect really (all between 835-890 or so). Calibration is saying 97mm is getting extruded on a 100mm gcode hence the 890 setting.
Cable thickness is all set up properly and playing around a half mm either side doesn't seem to make a difference either.
Any hints/tips Ultimanauts? Might it be dodgy material? Or is there some settings I've not taken into consideration?
