Hello All!
I'm attempting to print small parts with some decently intricate features. Having a hard time dialing in the settings and would like to ask for advice from fellow high resolution printers. I've attached a snip of my settings, which I tweaked from Google research and trial and error. I'm still not getting enough extrusion from the nozzle - is this from an extrusion width setting? I have the height set at 0.05 or 0.06 when attempting this.
The parts I'm printing are for medical devices and generally a 1" by 0.5" by 0.375" in size. Very small features. Usually a 0.4 nozzle with 0.1 layer height is fine, but I'm wanting to push the limits of this printer with the MicroSwiss nozzles until we buy our production printer.
Thanks in advance!

Re: Using a 0.2 nozzle - FFCP
I think your extrusion multiplier is to high to start with for PLA 90 is a general start point for PLA.
I would go back to a .1 or more layer and get things going before going to very thin layers. Also you will need to slow way down on the small nozzle.
Micro Swiss may have some recommended settings.

You didn't list out much info for us to go on. What specific problems are you having issues with? Any pics?
I would do .08 or 80 micron layers minimum. Remember every full step of the stepper is 40 microns so try to step 40, 80, 120 etc. 40 is probably out of range, but 80 and 120 are possibilities. Use the highest layers you can to render all the features of the part.
Yes, start slow, probably 20mm/s, it is a small part so you aren't going to be printing fast anyway due to acceleration limits. Remember the area of a .2 nozzle is 4x smaller than a .4 nozzle. Extrusion mult is probably high, 90 is a good start for all filaments. Extrusion width is probably fine at .24, but you can try .2. Your under extrusion is probably speed related, or maybe temp related. There are a lot more settings than the pic you posted.

I'll second the fact that we'll need more details of your current settings and the exact issues you are having.
Small parts are very, very feasible with a 0.2mm nozzle. Here's an example of what I've been able to achieve:
Modern cameras are not very kind you may notice....but viewed with just the naked eye, this cement mixer looks pretty cool!
btw....its printed in eight separate parts and glued together.
