Re: Filament suppliers

I've had 7 or 8 1KG reels from cd-writer.com. The black and blue ABS were a little "bubbly", however the last few reels that I have received are better sealed to help keep out moisture (one cause of bubbling). I also find running the plastic cooler helps a lot (either with a fan, or an extruder mod)...

Re: Platform heater repeated failures

I was hit by this one today. The problems are always worse when you've committed to an order ;) Just as pleppik found, the repeated flexing of the platform heater cable caused one of the wires to break completely. I'm assuming by the blackened insulation that it has been intermittent for some time a...

Re: Printing at lower temps for aftermarket ABS

I have been running this mod for about a week now and am really happy with the quality improvement it gives. However; One of the benefits I found with after market ABS was the stronger layer bond with running it at higher temperature. This is the only drawback I have found so far with using a lower ...

Re: Printing at lower temps for aftermarket ABS

Some details: As Julia pointed out, it is a 100 Ohm Platinum RTD. I used this datasheet for reference: http://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=6&cad=rja&ved=0CHUQFjAF&url=http%3A%2F%2Fwww.thermometricscorp.com%2FPDFs%2F100-ohm-plt-rtd-0.00392-in-C.PDF&ei=sSA0UODEEqmX1AXG-YGABg...

Re: Printing at lower temps for aftermarket ABS

Thanks for the inspiration! I received a batch of plastic that just didn't work well with the standard ABS or PLA settings. Having spent a couple of evenings making this mod, I am really pleased with the result of lowering the extrusion temperature! The buttons allow me to go between 180 and 260 deg...

Re: Infill/Perimeter

Olaf, Sure, no problem. I've only had my UP! for a few days, so no experience with text yet. The tip about closing the tops (bottoms too?) is great - that was going to be one of my next questions :) Maybe a tips + tricks sticky for the forum? Including the reference to Olaf's manual - I didn't know ...

Re: Infill/Perimeter

Thanks for the responses. To save other new comers the same pain, I have created some test prints. I found that the speed (Fine / Normal / Fast) didn't make a difference to the lines drawn, but it may affect the marginal results where it sometimes sticks and other doesn't. 0.4mm test print: Solid_Wa...

Re: Infill/Perimeter

Was there ever an answer to the infill not reaching the edges? I am trying to print a 2mm thick wall using .25mm, but both the inner and outer wall of the box have detached from the infill. A 1mm thick wall fuses ok, so is it possible to tell the UP! to print 4x 0.5mm lines rather than 2x 0.5mm + 1m...
