Extrusion Multiplier - How much away from 100% is to much?

Posted · Extrusion Multiplier - How much away from 100% is to much?

So this is a bit of a continuation of my other issues with over extrusion and first layer goodness.

Thats all been resolved I think.

After I calibrated my extruder steps/mm with no hot end connected, I then proceeded to set the first layer height, making it pretty close to that set in software (.3).

Thats all good now, then I printed a hollow cube to measure the the wall thickness to attempt to set the extrusion multiplier. With the multiplier set at 100%, I am laying down lines a tad thicker than the .4mm set in software.

So my question to you guys, How much deviation away from 100% is a sign something else may be wrong? Obviously in my other post I had to go down to around 30% to get proper width, thats how I found I was way over extruding.

Now I am at 93% to lay down a perfect .4mm +- .013mm. So is 7% deviation within normal ranges assuming filament size variations and nozzle diam, etc?

    Well when you dont have a scale that can read Sub grams, and all cura says is ~1g, weighing it is not really an option. There has to be a better way.

    I recently had issues with over-extrusion using ABS. My UM2 settings give ABS a 107% multiplier for ABS, but that was much too much on my new Type A Series 1 Pro.

    On the S1, even a 103% multiplier caused winkling and bumps in the prints.

    I'm guessing that this might be a difference between the UM2 remote-extruder with Bowden, and the S1, with 3" direct to the hotend.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
