It's a little more work, but you could generate gcode files with and without support and paste the later layers of the one without support over the later layers of the one with support and then save it in whatever Apple calls their plain text editing software.by IMBoring25 - Slic3r
The slicer could eliminate a feature like that primarily in two cases... If the feature is too small to be printed at a given nozzle diameter/layer height or if the STL is non-manifold, which Slic3r doesn't always do a particularly graceful job of repairing.by IMBoring25 - Slic3r
The auto-center function is not based on the maximum limits of the part. For something that's not symmetrical and so close to the build plate size it matters and you will need to turn off auto-center and align it manually. I think the setting is in one of the first couple of menus but don't have the software in front of me.by IMBoring25 - Slic3r
It was not clear from the original picture it's hollow. New theory... Your cooling settings are slowing down the layers starting where the base "disc" goes away and as the diameter increases the larger diameter naturally takes longer and speeds the print back up. It might be that something in moving more slowly is causing you problems, either minimum step rate or the resolution at which you canby IMBoring25 - Slic3r
For the holes, how much skirt are you printing to purge and charge the nozzle? For the roughness, it kind of looks like the pattern I get when my Z=0 is too low and the bottom solid layer perimeters get squeezed almost exclusively outward.by IMBoring25 - Slic3r
Kind of apples and oranges comparing UL-listed consumer products the core technologies for which haven't substantially changed since the '50s against products homemade partially from repurposed off-the-shelf components to provide capabilities that mere years ago were the realm of science fiction, in many cases for lower purchase price than the consumer products. I'm reasonably comfortable mine aby IMBoring25 - Slic3r
I wondered if that was what you meant. When you're configuring axis directions, you should always look at how the nozzle is moving relative to the print surface, regardless of which of the two is doing the movement. If positive Z movements move your nozzle and bed closer together, you need to either change Z axis direction in the firmware or reverse the wiring on the bed steppers, then make suby IMBoring25 - Slic3r
That line separates the nozzle and the bed by 5mm so the nozzle doesn't hit or scrape the bed on subsequent moves. The comment assumes it's the nozzle moving but in actuality it doesn't matter. As long as your Z coordinates correspond to how far away the nozzle is from the bed it's fine. The comment (which starts at the semicolon and ends at the line break) is ignored by the printer, so you caby IMBoring25 - Slic3r
I've seen this behavior and found it troublesome as well. The workaround I devised was to have one or more layers at the bottom of the bridge that omit every other section of the platform. Then it will alternate between a clean support-to-support bridge and an empty space. When it gets to the first complete layer, it will be bridging the previously-omitted regions from one clean platform sectiby IMBoring25 - Slic3r
I was on my phone and gave the most likely answer (especially when starting with a Sketchup file). Even had I been home I don't have Sketchup on any of my machines right now.by IMBoring25 - Slic3r
In the lower right corner Slic3r will tell you if the model is manifold. If it's not, Slic3r tries to repair the model, with usually poor results. With a .skp extension, it's a pretty safe bet you're not generating a manifold STL. If that's the case, run it through a more robust mesh repair program like Netfabb or Meshmixer (and for the long term, find a different CAD program).by IMBoring25 - Slic3r
Since neither power supply will run the bed with anything left over to run everything else, even if the board would handle it, it would probably be cheaper to get a good SSR than a new power supply of the power required. Do not even think about skimping on the SSR. The cheap ones fail a lot and fall "on.". Crydom and Auber are purported to be good brands. I use Crydom D1D40s on my machines andby IMBoring25 - Duet
If the gcode correctly commands Z = 0.4mm for both extruders, it's not a Slic3r issue and the most likely place to look is in either your firmware or EEPROM for a Z offset for one of the extruders. I can't be more specific without knowing what kind of electronics and firmware you have.by IMBoring25 - Slic3r
Do you have them in a single STL or are you loading two STLs? Are the STLs showing as manifold in the status bar?by IMBoring25 - Slic3r
Speaking of G10, is there a reason it waits until the specified tool is activated to implement active and standby temperature changes since I upgraded to the 1.17 branch?by IMBoring25 - Duet
I'm using Netfabb Basic (which they've apparently rolled into the main Netfabb, but the repair capability ostensibly remains after the 30-day trial of the paid features expires). I've also heard some say they use MeshMixer, which is free.by IMBoring25 - Slic3r
I would say it's not just possible but probable that the repair is responsible. I don't even try loading anything without running it thorough a mesh repair software first anymore.by IMBoring25 - Slic3r
G92 E0 just resets the indexing of the extruder to zero. You're slicing in absolute extrusion coordinates. I've never seen any compelling reason to do so. What is the F parameter of the last G1 command that has one up to the infill in question?by IMBoring25 - Slic3r
Do you have the native CAD file to be able to make a shell that consists only of that perimeter? If you load that STL as a modifier and change some meaningless variable (infill percentage?) you should be able to treat that perimeter as a separate solid and force it to be continuous.by IMBoring25 - Slic3r
With a traditional bridge supported on a lower layer, you have overlap on both sides of the bridge and all the bond has to do is resist being drawn towards the void as the bridged filament tries to sag. If you bridge within a layer, not only do you have what's in essence a point contact at each end (very weak), but the adhesion at those point contacts would have to directly support the full weigby IMBoring25 - Slic3r
I don't know if any of the slicers handle that gracefully without support material. There's no destination point for a bridge due to the hole. In order of preference: 1) Orient the part so holes in x-y planes touch the build platform if that doesn't cause other problems. 2) Design the model with the hole filled in layer 21 and: 2a) Backdrill through the rest of the layers where the hole is pby IMBoring25 - Slic3r
This is an easy thing to do manually in the sliced gcode file using a text editor once you know which commands to use for your specific firmware. In RepRapFirmware I use, at the point where I want to pause (you can search on G1 Z for the coordinate you want): G1 X* Y* (whatever puts the nozzle where I want it) M400 M226 M400 The M400s clear the buffer so the pause doesn't get out of order witby IMBoring25 - Slic3r
102% will usually not be an appropriate setting for extrusion width. It is computed against layer height, which is usually recommended to be no more than around 75% of the nozzle diameter, so if you're following that guideline you're setting extrusion width to just over 75% of the nozzle diameter or less. Extrusion width should usually be equal to or greater than nozzle diameter.by IMBoring25 - Slic3r
It took me a while to figure that one out myself. Your issue is a checkbox in the SolidWorks STL output options, something along the lines of "translate output into positive space.". That moves each STL so there are no negative coordinates and needs to be unchecked to retain the original (same for all parts) coordinate system.by IMBoring25 - Slic3r
Slic3r calls it "Combine infill every * layers."by IMBoring25 - Slic3r
You can put M140 S in the start gcode where you want it to start heating. You will ultimately need to pass an M190 to keep Slic3r from prepending its own M190 command and overriding what you're trying to do. Note that, if your machine is near its power limits, it may not be desirable to have both heaters in the initial heating phase (when they'll be drawing their most power) at the same time.by IMBoring25 - Slic3r
You must have a fairly large Pattern Spacing value on the Support and Raft settings. There's no real reason for it on this since the interface is with support material and you're not looking for a shear plane there anyway. You could probably even use zero with no ill effects.by IMBoring25 - Slic3r
Actually, the nozzle diameter might slightly change things because the manual says in the section about tuning dimensional errors in holes at that Slic3r tries to guess the cross-sectional shape of the extruded material, which could be different depending on how much squash is happening to get to a specified layer height and extrusion width. However, if you model the extrudate as a rectangularby IMBoring25 - Slic3r
Puzzling. I tried both the 5-gear version and the 6-gear version and they both sliced fine for me.by IMBoring25 - Slic3r
