Topic: S3D + Repetier = Bad Day

I was having issues with gaps in between parameter and infill in a print using Simplify3D, I had tried higher infill, slower speed, setting the extrusion to 150% and still the same thing. ssauntson recommended I check the stepper since I was using a different one. I marked 100mm of filament and told S3D it to extrude 100mm. It only extruded approx 94mm, we thought we should adjust the steps in the firmware so we increased to 510, it extruded the exact same amount. So with that I tried Repetier Host and it over extruded by approx 6mm. I reset configuration.h to original value, extruded with Repetier Host and it was almost dead on with 100mm.

Why would Simplify3D not extrude the correct amount? I have also created a ticket over with S3D but was wondering if anyone had any ideas. Can someone else try the same test with Simplify3D?

Re: S3D + Repetier = Bad Day

https://www.simplify3d.com/support/prin … eshooting/

Simplify3D includes a settings that allows you to adjust the strength of the bond between the perimeter outlines and the infill. This setting is called the “Outline overlap” and determines how much of the infill will overlap with the outline to join the two sections together. This setting can be found by going to “Edit Process Settings” and selecting the Infill tab. The setting is based on a percentage of your extrusion width, so that it easily scales and adjusts for different nozzle sizes. For example, if you are using a 20% outline overlap, it means that the software will instruct the printer so that the infill overlaps with 20% of the inner-most perimeter. This overlap helps to ensure a strong bond between the two sections. As an example, if you were previously using an outline overlap of 20%, try increasing that value to 30% to see if the gaps between your perimeters and infill disappear.

I would check the above setting  I am running 16% overlap in RH so 20% seems plenty high . but IMHO a very good place to look.

hope this helps

Re: S3D + Repetier = Bad Day

I have also tried that with no change, curious if you guys are getting 100mm extruded with S3D and Repetiere firmware.

Re: S3D + Repetier = Bad Day

sorry I am using slic3r , rh and marlin firmware. seems like changing the setting should help are you saving the change ? I have done that before forget to save a change config profile or save it only to realize I am using a different profile. 
I hope someone actualy using simplify3d can help. but if you are making changes and nothing is changing something is amiss.
And it could be operator headspace happens to the best of us.   I would be looking over the s3d support page and tutorials. you are likely missing something simple. Wish i could better help.

Re: S3D + Repetier = Bad Day

Set your wall count for multiples of your nozzle width. Then see what you get.. It's not an extrusion amount issue but a dimension issue.

Re: S3D + Repetier = Bad Day

The first picture looks more like mechanical backlash to me. The width of extrusion in the first picture looks just fine. Notice how the infill meets the perimeters on the far left and right in the first picture. This is what makes me suspect it's a mechanical issue and not a software problem. Did you print these in the same orientation in RH and S3D? From the infill lines it seems not. The second image is over-extruded, probably hiding the mechanical backlash in the print.

Check your belt tension, especially the Y axis. If I had to guess, your Y axis has a bit of lash. The circle on the right of the first picture meets the infill everywhere except 11 o'clock and 5 o'clock. If that picture is the same orientation as you printed the part in, the issue is your Y axis.

Re: S3D + Repetier = Bad Day

I have printed the same part several times and only RH/Slic3r had acceptable quality. What really concerned me was the 100mm test. I purposely told RH to over extrude, I did the same with S3D, the first pic was 150% extrusion override.

Re: S3D + Repetier = Bad Day

I'm someone who uses Simplify3d, but I just bought it and am not knowledgeable. <-- Very important comment wink

What I am curious about is the command your using on both RH and S3D to extrude the 100MM. If you were to write that to a file, you'd easily be able to see if the gcode was correct or not.

The only thing I can think of in S3D that would alter the expected amount extruded would be the Extrusion Multiplier not being set to 1.00 if your sending to a "normal" printer that uses gcode. My printer is not normal in that respect being a Makerbot mightyboard clone, so with those it is more of a job since you must change the settings gpx.exe uses.

Re: S3D + Repetier = Bad Day

I use s3d and I extrude 100 and I get 100.

Note however when you are printing you can adjust the value check your process and look at the extrusion multiplier.

if its less the 1 then you will print if its more then 1 you will print more.

The next thing is make sure your nozzle diameter and extrusion width are set correctly.

Looking at your photo it looks like this may not be set right.

one other thing to check is what you have listed as the filament diameter

if you preview your print first you should be able to see if the infill is touching the perimeter or not.
