Ray - so the slow speed test do look much better - that's progress! How did you calibrate your extruder? I'm assuming when you say "flow at 75%" that's using your host program to regulate it?

Test prints
Because my printer is not printing very well -- cruddy -- compared to others I've seen
I want to solve the problems and understand the parameters in slic3r and RH


Sysguy
Using Repetier-Host and set feed and flow bars on GUI

Extruder calibration run 100mm extrusion and then calculate and adjust

I should set your test config to my PLA calibration!!!

Ray - if you have measured your filament and adjusted your e-steps, you shouldn't have to mess much with the flow in Repetier - I've had not-so-good results with that in the past.

Try doing a 20x20 cube, with flow at 100% in Repetier, and with your proper filament diameter in Slic3r, 100% infill, and with extrusion multiplier set to .95. Make sure you fan is on after the first layer.

I suggest that you concentrate on printing the single-wall object according to the instructions in the slic3r calibration wiki and get it to come out well with the correct extruded filament width before trying to print anything else. This instructions assume that you have the correct x, y, z and e steps per mm in the firmware and you have entered the feed diameter into slic3r with a starting value for extrusion multiplier of 1. Note that e steps per mm doesn't have to be exact. It can be within 1% or so and it will still be fine since the extrusion multiplier basically adjusts for this.

why are you using such high temperatures? PLA is usually printed at 185-190

How does a single wall object look like?

Test.config from SystemsGuy

viewtopic.php?f=33&t=1732&start=30#p18004

has ET temp of 225

He suggested I use it?
