Slicer seems to miss bits?

imo you are not well calibrated for the flowrate... it's not a problem of slicer

the second picture is a problem of 'not enought plastic'  ... you need to reduce the space between your head and the bed (use the z bed screw for a global move).. or ramp up your flowrate

the first picture is not a problem of missing part, but a probleme of 'too much plastic' (reduce flowrate) or the bed is not enough clean (use acetone) and the plastic did not stick well on certain zone... (where the plastic inflate) or the two...

it can be a speed problem but i will not put a bet on that...

for the  lumpy edges, it's a problem of too much plastic extruding...each 'line' of platic is made of 100% of one line and 50% of the next one... when the second pass over the first, the head crushes the two lines and if they are too many abs, it overflowed.. (the lumpy edge)

i'm sure it's a problem of bed calibration AND flowrate...

Making a new slicer config based on the original solidoodle ones helped I think. However...

I have been adjusting the flow rate on the fly with very interesting results. The numbered areas in the attached images are where I changed the flow rate.

I started with the flow rate at 100 (area 1) then turned it down progressively in each area to eventially settiling aroung 70%. Interestingly, when I was printing the same part with 0.1mm for the first 3mm of layers then 0.3,, layers for the rest *, I had to switch it up to almost 150%. The part is still printing so will let you know if I have to change the flow rate when it gets to the 0.3mm layers.

(*multiple layer height in single part fuction of newest slicer)

From memory...

zone 1: 100%
zone 2: 125% (I think, I definitely increased it)
Zone 3: 90% (Started to decrease here)
zone 4: 80%
zone 5: 70%
zone 6: 75%

I think you can get rid of this problem by following the extruder calibration instructions on Ian Johnson's blog.  I had similar problems resolved by doing this and have never calibrated x, y, or z.

I've tried levelling my bed a number of times and I'm pretty sure it's warped, especially when it's hot, so I have some glass on the way from here http://www.charlies3dtechnologies.eu/Gl … 55981.aspx

extrusion multiplier is set to 1. Is this the same as flow multiplier, if not, where exactly do I find that? I know flow rate and feed rate are different.

justsomeguy, do you have a link to that blog you speak of please?

yup, extrusion multiplier is 1.

I haven't done any calibration on this as yet. Do I NEED to calibrate it that way, or could I keep adjusting it on the fly with the flowrate slider in the manual controls of repetier? I turned it down for 0.3 layers but up for 0.1 layers

I have calibrated my extruder. when I told it to extrude 100mm of filament it only extruded 77mm. Giving me a multiplier of 1.33 correct?

Well I've just started a couple of prints in 0.3mm layers, with a solid fill. The parts 2 parts are a mirror image of each other created from 1 part so they should come out exactly the same in terms of print quality... but they aren't.

One of them isn't printing solid (1 density), and both are still getting 'missed' areas and lines.

See attached..

I think my print bed STILL isn't level or is completely warped? The more I try and improve this the more I get confused!

Ok, i'm back, ive calibrated the shit out of everything, updated to the latest version, and come to this conclusion...

Too much flowrate on the first layer only. If I do the flow rate at 70% for the first layer then back to 100% for the rest it seems to work.

I think theres a bug in slicer maybe?

Take a look at the attached image. The smoother one was done at 70% for the first layer
