No, the Flow rate or Extrusion multiplier is to compensate for different materials and temperature ranges. Where does the factor come from? Let's say we calibrated our nozzle for work at 200°C with PLA, so 100 mm extrusion are correct and want to print ABS. ABS behaves differently and we get bad prints. What is wrong? Well, they do behave differently in the ...

SHORT ANSWER You're not supposed to do the single-wall perimeter thickness test to calibrate Simplify3D. That screws up the extrusion volume. The correct volume calibration procedure for S3D is: Measure actual average filament diameter and input that Print a 100% infill calibration cubes If the print is over-extruded (top or sides bulging), decrease ...

Self intersecting meshes are considered dirty, yes. The reason you haven't had trouble before is probably that the software you were using was cleaning your mesh for you, behind the scenes. Generally speaking, these meshes can be cleaned without too much trouble by software like netfabb (https://www.netfabb.com/) which has a nice free version that I use for ...

In addition to the very detailed answers above, I would like to mention that the hardness of the filament plays a role too. Most feeders are spring loaded, therefore it depends on the hardness of the filament how far the teeth of the driving gear do sink in. The deeper they sink in, the smaller the effective diameter of the driving gear becomes. Therefore ...

I doubt this is a printer or filament issue. Rather, I suspect it might be related to how your slicer handles bridging scenarios (which basically is what laying down layers over infill is). You could try to: Increase the infill percentage and/or use an infill pattern that provides better support for the top layer (so that it isn't allowed to sag as much). ...

No, choosing a different filament type will not result in a different size (unless you use PLA that foams on extrusion, it increases size but then again all other dimensions would not fit either as it expands uniformly). The overall dimensions are defined by the coordinates in the G-code file which is based on the geometry of the model. If the printed model ...

Of course it can change size... but definitely not in scale you've presented. Filament as same as many other materials can subject something called shrinkage. It depends on physical properties of the material and as its name suggests cause the dimensions to shrink. Here is wikipedia article. The same happens to almost all plastics. But this phenomenon is ...

The infill percentage is a bit low. Even with infill percentages that are higher than 15% (I use 25%), a single layer on top of infill will not create a good top. It takes at least two and looks really good with three. The first layer is often patchy looking! If you're stopping your print after one layer, and have more layers to go, maybe let it continue ...

You could experiment with the 'cleaning' part of the startup gcode shown here G1 X100 Y0 F4000 ; move half way along the front edge G1 Z1 ; move nozzle close to bed M109 S200 ; heat nozzle to 200 degC and wait until reached G4 P10000 ; wait 10 seconds for nozzle length to stabilize G1 E10 ; extrude 10 mm of filament G1 z15 F12000 E5 ; move 15 mm up, fast, ...

The best thing you can do for a large ABS print is to have an enclosure heated to 50C or better. For example, see this, this, this, and other search results.

The picture is not very clear so this can be related to either: Overextrusion at the bottom layer (slicer setting) or an incorrect bed leveling (bed to nozzle distance too small), or this could be the effect called "elephant foot" that is primarily caused by printers with a heated bed. This issue is related to unbalanced printing parameters: heat bed ...

The first indication for print speed and temperature should be taken from the box the filament comes in. Generally it specifies temperature ranges for the hotend and the heated bed. Sometime, mostly online, more parameters can be found amongst which is the printing speed. Do note that temperature and printing speed are linked, if you want to print faster ...

You could mount your google drive using gdrivefs on your pi following this tutorial: https://www.raspberrypi.org/forums/viewtopic.php?t=109587 However, I have to ask: why send the file to the internet? Is your printer/pi on a separate network than your desktop where you are slicing? If they're on the same network, you'd be better off setting up a samba ...

Version 4 allows you to have multi-process vase mode prints -- do the vertical surfaces in vase mode, then switch over to normal mode for the horizontals. This lets you have the best of both worlds in the same print. :)


3

Any ideas what to do to prevent this from happening? You cannot prevent it entirely, but you can probably mitigate the problem by depressing the lever that squashes the filament against the hobbed gear of the extruder before starting to heat the nozzle. In bowden extruders, the long portion of filament between the stepper motor and the nozzle is subject to ...

What you are describing is not possible as a result of changing slicers, this must be an intermittent hardware issue. The slicer has no knowledge of the hardware layout of your machine (other than the build volume and gantry dimensions; if properly configured), it just creates slices of the model you present which are found in the G-code file as Z movements....

If the cad model was imported from Solidworks into Simplify3D. Push "Center and Arrange" button to place the model in the middle of the Heat Bed. There might be a gap between the object and bed level that is hard to see.


3

If you can, set your slicer to do honeycomb fill. Depending on the weight requirement choose maybe 10% - 20% fill. That ought to do the trick. It won't be solid, but it should be strong enough. What are you going to put on the platform?


3

Two things. First for a first layer from infill this is not unexpect. This is why you do 3-4 shells with such a sparse infill. Most of the time we also have the first layer at a slower speed. Often we will get to this point and the difference in flow can be contributed to the temp to speed ratio. Try increasing your temp, or decreasing your solid layer ...


3

That's one way to look at it, I guess. I think a more accurate way is to consider it an "ad-hoc calibration" where one realizes that their printer isn't extruding enough/too much and the EM adjusts the flow to extrude the correct amount. The underlying calculation, at least the main one, would be the steps/mm set in the firmware. If it's off, one fix is to ...

When using Simplify3D, you may try referring to their awesome troubleshooting guide: https://www.simplify3d.com/support/print-quality-troubleshooting/#holes-and-gaps-in-the-top-layers 3 reasons (from the guide) for gaps in the top layers: under-extrusion: you may try to increase extrusion multiplier to see if this helps low infill percentage: not likely in ...

Changing the Simplify3D start script to this will change the nozzle purge to the same length as what was on your SD card. G28 ; home all axes G92 E0 ; zero the extruded length G1 Z10 ; lower G1 E20 F200 ; purge nozzle quickly<---------Change E20 to E3, E is the extrusion length G1 E10 F60 ; purge nozzle slowly <----------Remove ...

What printer are you using? I had a friend who encountered this problem, at first we thought it was the slicer. Turns out, the wires for his extruder heater block and hot end fan were shorting, so whenever the extruder was turned on, it would keep heating no matter what the temp was set to. To test if this or something similar is happening, first unload your ...

It appears to refer to calibration factor called Width over Thickness. From Calibrate your 3D printer to print parts to fit Here is the list of necessary variables for this calibration to work, Carve/Extra Decimal Places (float) : change to 5 Carve/Edge Width over Height (ratio) : nozzle diameter/layer height Inset/Infill Width over ...

While using rafts with PLA is a good idea due to warping, PETG is a material that requires very little build plate adhesion. When I printed with PLA, I would normally use a two layer raft with a 0.3 mm air gap. With PETG, however, I only need a skirt. I recommend calibrating your extruder height so that when you slide a piece of paper underneath, you ...

When I started work on mine, the bed leveling and radius (Delta-only issue) were horrid, and my erstwhile assistant was fond of using a LOT of glue stick, which sort-of made things work, though in many cases with no first layer extrusion. As I sorted things out, I found an apparent bug (Repetier Host (Mac) and Marlin 1.1.0-RC8 firmware - not sure which side ...

The free slicers are catching up with Simplify3D, and are even overtaking it in some areas, so purchasing it may not make much sense to hobbyists. However, for professional print shops, where printers may cost twenty times as much (or even more), 150 dollars is nothing (especially since it is 150 dollars per PC, not 150 dollars per printer).

XYZPrinting printers use a .3w file format vs GCode on all opensource printer designs. I have used Simplify3D since the first month I obtained my Da Vinci Pro 3 in 1 which also has WiFi enabled. Simplify3D does not connect very well to my Da Vinci WiFi so a 25ft ActiveUSB extension makes the connection for uploading and monitoring the progress of the print....


2

To address the 'cheating or not' aspect directly. There are several other parameters (steps/mm, nominal filament diameter) which have a direct equivalent impact on the end result (at least ignoring small 2nd order effects like the retract distances). As a purist, you might argue that these could all be rolled up into a single calibration parameter in the ...

So as someone else on here mention, those settings shouldn't be for the model but for the filament. Sadly, you will need to test 99% of filaments to really figure this out. I have a modify tester, and on the description it tells you how to set your temp. https://www.thingiverse.com/thing:3347967 You can look at the remix if you want to grab the blank model ...
