Re: Extruder Jam and stuck fillament Pro2

Happy to report that since replacing the fan with one from Jaycar and adding the inlet nozzle we have had no issues at all. I've attached the STL of the inlet nozzle if anyone is interested. Fan inlet cone.STL As mentioned earlier my original fan sucked the hot air from the head which apparently is ...

Re: Extruder Jam and stuck fillament Pro2

I believe I may have a fix for this issue. Based on the analysis from Jetguy, I too believe the problem is that the cooling is not good enough. PLA has a glass transition temp of just 60deg and past this temp, does not have the structural integrity to push the molten PLA through the nozzle. As I thi...

Re: Extruder Jam and stuck fillament Pro2

I have exactly the same issue with our pro2. The fan lasted 5mins before the majority of the blades simply fell off. This may well have something to do with the rated max temperature for the fan of 70deg. :? We've replaced the fan with a similar format fan but now the nozzle is continually getting c...

Re: Inefficient extruder motion in IdeaMaker

Yes circular infil for a circular structure is what I mean. The only difference between a model with full shells and no infill is the use of fillament, time and inibility to use 2nd extruder or different material although I'm not certain about that last point. I will try to post a picture of what I ...

Re: Inefficient extruder motion in IdeaMaker

yes that would make infill of circular items stronger and more efficient to print. An extreme example is a cylinder that has a 1.5mm wall thickness. For this I had to increase the number of shells (hence, no infill) so it would print in a circular motion. The time saving was hours.

Re: Inefficient extruder motion in IdeaMaker

Any advance on a circular infil?
