Re: the temperature of the motors overheat the extruder unit

dinogoal, I'm running an N2+ so everything is a little different BUT - I did have some issues with heat creep initially and found that putting a simple shield between the heat sink/cold end and the hot block helped significantly - especially with long prints and with thin layers or small nozzles (wh...

Re: the temperature of the motors overheat the extruder unit

I (unfortunately) scavenged my heatsinks from scrapped PC's and Laptops - just trimmed them down to the shape of the motor - sorry... There ARE concerns about clearing everything but even a shallow (1/4" deep fins) heatsink can disperse a lot of heat - especially when the cover is off or open -...

Re: the temperature of the motors overheat the extruder unit

I can completely agree that the motors DO heat the factory extruder block quite a lot - especially on really long print jobs - I glued heatsinks to the backs of the stepper motors - no added fans (yet) and it helped a lot. Be sure to keep the fins vertical if you want the best convection cooling - l...

Wind Turbine

This is an item originally generated in OpenSCAD and posted in Thingiverse and I re-mixed it a bit for the larger capabilities of the N2+ platform. This one is nearly 200mm across and almost 300mm high. Printed in vase mode with a 0.60mm nozzle, it was reaching the point of being too unstable to gam...

Re: Drying filament under vacuum

I'm really intrigued by this information - My reading had suggested that the plastic materials needed to get warm to release the moisture and that a vacuum oven used the low pressure to speed up the process but there was no indication that it would actually remove the moisture by itself. It also sug...

Re: Optimizing for printing hollow/empty objects

I'm far from being an expert on this - I don't go into my g-code files or even use outside slicers, BUT... I have seen some REALLY crazy print files - Sometimes, there is a lot of "gap filling" happening where I see the head go back to an area that appears complete but it may make 3-5 more...

Re: Tramming/Leveling the bed

I have to agree with Vice Chief - I run a quick check at temp when I change filament types - especially when moving from one extreme to another. I am not sure if there is an answer to this - I have a friend who is very engaged in the heat treating and tempering of aluminum for what he does (which ha...

Re: How THIN a layers have you been successful with?

I have printed some 0.05 mm layer pieces in my post "Artifacts" and they are all remarkably smooth but show small issues so I got bold and tried to print a part that I really wanted to get a clean print with nice finishes because I have mostly finished playing with the design and wanted a ...

I'm not sure exactly what you are doing, but it might be of interest that there are a significant number of "filled" filament products - These range from simple wood powder fill, chopped glass to carbon fiber and even metals - there are even specific metal filaments that were designed for ...

How THIN a layers have you been successful with?

I have been trying to push the overhang limits w/o using supports - especially to finish the upper portion of round holes placed horizontally in parts. To try and manage that, I have been using a 0.6 mm nozzle and using thin layers to help with the staggered layers around the holes. I seem to be abl...

Re: Shells vs Infill

Re: Bouncing or jumping during infill

I may not have the completely correct answer but I suspect that the flow rate for your infill is too high - so the infill walls are a little taller than the actual level the head is expecting to print at. I have had the same problem many times but always got past it by decreasing the infill flow rat...

Re: Extrusion width in ideaMaker

As Vicky has sent a link for - the extrusion width is a setting - independent of the nozzle diameter in the printer settings How do the two settings differ or relate to each other? I was guessing that the value for extrusion width in the slicing profile took precedence (as you can set the two extrud...
