However, I have reduced the extrusion multiplier, and also the extrusion width to 4.0, and maximum infill I use for solid parts is 90% density. These settings seem to be the best working yet for solid parts and general printing. I've tried the profile on 2 different printers, one with glass bed and cover, and one without both, and the results were more or less the same.

The finish of the first layer is pretty good too, but I've done better by manually adjusting the flow-rate on the fly. I plan to improve this profile further.

I have attached the config file.

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

follow this:

http://solidoodletips.wordpress.com/201 … libration/

you need to change the value in 'Default Axis Steps per Unit. ' for Z in the EEPROM (RH menu..)

to see if it's warp, put a piece of glass of the same side on the bed and see if the glass 'wobble'when you gently push on it on different zone...

or use something very straight (a ruler) on a the diagonal of the bed..

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!

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

The front control panel is a control of this - so if its .79, 110% on the front control panel is actually 110% of .79, not 110% of 1 - unless you've set the multiplier to 1.

If you've done filament flow calibration as per http://www.soliwiki.com/Calibration_of_the_flow_rate it'll prob be .79 to .85ish... 1 is way too high.

When you say your bed (kapton) is flat is this when it is up to temperature? also have you thought about making some fairly thin mix ABS glue and applying it as the first layer this should yield a smooth surface.

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?

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%

the good zone are 4/5/6 ... so it's too much abs in zone 1...

i don't understand your results... but your method is good...

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.
