L Nozzle Default Flow Rate 94

Postby Casale8 » Wed Nov 29, 2017 5:11 pm

I noticed that the default flow rate 94 for the N2 printer out of the box and any print is 94, no matter the setting I have from the idea maker software.

This has seemingly caused issues with Printing one of my materials.

Is there a reason for this 94 setting?

Hi Casale8,

The Flow rate should change when you change the material type on the printer. Please check your settings in ideaMaker under the "Printer" tab, then "Filament settings" and see the material of choice's flow rate. PLA will be preset to 94% and if you tab over to ABS it will be set to 100%. The printer should use these values when running the G-Code.

Banging my head on the wall. Thanks... I should have remembered this.

How does the gcode affect the flow rate as seen on the controls on the front of the printer? I'm slicing with another package and just using the gcode directly. As noted earlier, the printer defaults to a flow rate of 94 no matter what goes in the gcode. And each time I have to punch it up to 100% on the front panel to get desirable results.

The controls on the front of the printer read the code and give a value based on the ones prescribed in the slicer. My post stated "change the material type on the printer. " but that is meant to say "change material type in the slicer". The printer, for the most part, has no clue what is being run through it. I would ask to see if your slicer is also preset to default to 94% as well or if there is another setting you may have missed?

Ah, I need to add comments in the form:

flow rate for ideamaker is also known as extrusion multiplier to other slicers.

it's a separate setting that acts globally. in many slicers, you have different multipliers for different types and parts of the model (shells, infill, solids, etc)

no, I am telling you how the Filament setting for Flow Rate works in Ideamaker. it is how raise3d designed.

On your Filament settings, Flow Rate determines the default extrusion multiplier or flow rate of that filament, the parameters of the slicing profiles are on top of the flow rate set on the filament settings.

all the profiles for that given material use that flowrate for their settings.

if you are using PLA profiles, they will have 94% flow rate set.

To calibrate your flow rate, it is the same as calibrating extrusion multiplier.
set it to 100% on the filament settings.

load the sample model for the 20mm calibration box
pick a profile, such as Standard Quality or make a copy of one
set infill to 0%
set shells to 1
set first layer height equal to layer height
on the infill tab
set bottom solid fill layers to 0
set top solid fill layers to 0

slice the file and print it out.

using calipers, measure each side in two places and write down the results. you may want to not measure the bottom layers though.

add the 8 numbers you measured and divide by 8 to get the average.

new flow rate = old flow rate x (nozzle size / average of measurements )

old flow rate is 100
nozzle size is .4

once you have the first new flow rate.
change the flow rate on the filament and print the calibration box again.

take the measurements again and do the calculation again.

enter this new flow rate into the filament settings.

print the calibration box again but at this point you should be very close to getting your flow rate calibrated. It ultimately depends on how much time you want to spend on fine tuning it.

M220 is feedrate which applies to all movements
M221 is flowrate which applies to extruder rate.

Other slicers like to call M221 Extrusion Multiplier sometimes.

Marlin refers to it as Feedrate and Flowrate
Ideamaker uses the terms that Marlin calls it.

I'm sorry, but i don't understand which eight results i should compute to get the average. Could you please elaborate ?

don't mind, i could have looked it up to begin with ...


Print out a cube
(20mmx20mm would be nice)
in vase mode (single outline, no infill, no top or bottom layers)
set your extrusion multiplier to 1
set your extrusion width to equal the width of your nozzle.
Measure the walls with a caliper in several places (at least 8) and get an average.
Change your extrusion multiplier: new multiplier = old multiplier x (extrusion width / average measurement)
Repeat until you are happy.

I forgot to include "each side in two places" I fixed it.
