Hi everyone.
Got a m200 last week on friday and since I have been doing 1/2 prints every day, 10 in total now..
prints are done in ultra-T most at 0.19 normal speed. 1 at 0.14 normal and one high speed. and some variations with random/normal seams.
I started getting burns after the third print or so. SO first thing I did was cleaning the nozzle before print (acetone cloth). and making sure during calibration there was no curl of filament before head starts printing. Also did a recalibration of heatbed and after 6th print I did the ABS-juice thing because I was getting warping.
here's the pile so far.. (I am giving it a try to remake mu paper led light in 3d print)
burns are already appearing when printing the first layers of object
and another one raft side:
this is burn at seam (seams were random but when random chosen seams only appear at every edge of pentahedron).
this is when normal seam is chosen:
and another one with normal seam:
out of 10, only 4 are 'almost' without burns.. the other 6 have very visible burns which are really visible because of white material and no intention to sand/paint.
Although I clean my head after every print the head is really dirty after print:
what can be the reason for these burns?
there's one thing I don't know if that's related.. because burns also appear with normal seam but when doing random seams the head has to move sometimes and I noticed that sometimes it makes this squaky noise: you can hear it in this video.

the noise only appears when doing a n movement of the head from left to right and this movement is caused by placing of random seams so it does not happen every layer.. I had to record 5 minutes of video to hear it again. Could it be that something is loose? and therefor also causing trouble when doing the normal seams (when head is never travelling that fast in x direction..
any opinions?
I think the burns are really ruining the otherwise good prints.
