This sounds like a similar problem which I have had recently. The first few prints are usually okay but after a time the print will fail, the extruder drive is still visibly running but no filament is being extruded. In my case the problem was that the bolt which goes through the large extruder gear and holds the hobbed bolt was loose. This caused the hobbed bolt to move off line slightly andby RossHaddow - Ormerod
I've searched the forum but can't find an answer so I thought I'd put the question out there. I've printed the part shown in the attached photo and after measuring it discovered that the overall dimensions are within 0.1mm of the drawn measurements with the exception of the distance between the channels on the top surface. Why is this and what can i do about it. Are the channels suffering fromby RossHaddow - Reprappers
Thanks, time to do a bit of experimenting I think.by RossHaddow - Reprappers
I printed it in ABS. I did have to use support material for the inside to prevent the top from sinking. Perhaps I am being too picky about the finishby RossHaddow - Reprappers
Hello, I have printed a thin walled hemisphere for a wind speed indicator, please see the attached photo. I was wondering if anyone had and thoughts on how I could improve the surface finish. If you look closely the outer perimeter has gaps scattered across it. Is it possible to close these up or is this just a limitation of printing thin walled objects? I don't seem to have this problem with sby RossHaddow - Reprappers
I thought I would just confirm that this has solved the problem. Thanks for your help.by RossHaddow - Reprappers
Yes Greg Frost! That makes Sense, and I didn't think to try that either. I'll give it a go and see if I get an improvement. Thanksby RossHaddow - Reprappers
Hi I wondered if anyone else has had or knows of a solution to a printing problem I'm having with my Reprap Huxley. I've done a search through previous threads but couldn't find anything conclusive. The problem is more obvious on cube shaped objects. When printing a cube the final part appears to be tilted in the y axis plane. I've attached a photo of two cubes side by side to try and highligby RossHaddow - Reprappers
