Re: poor binding layer to layer with ABS

Are you using an enclosure for the printer? ABS is very sensitive to temperature, and requires a very warm (hot even) air temp around the part in order to avoid the layer-adhesion problems like you're encountering. Drafts can also adversely affect the printing - so the best solution is an enclosure ...

Re: next single extruder for TAZ 6

If you decide not to undertake repair, don't throw that broken extruder out! Put it on eBay, or such like -- there's a lot of folks who'd love to rebuild it for a spare or just to have an easy way to change nozzle diameters...

Re: Lulzbot mini issues

I sold a mini six months ago -- and was really worried that the buyer would try the latest Cura, and that disaster would ensue as a result of the new software. I'll take responsibility for my packing and boxing of the unit -- but it would really really suck to have to accept a return from a buyer du...

Re: Taz 2 evolved to 4

If you're going to change the power supply to a 24v system, you'll probably need to change the bed as well. There are ways to get a 12v bed working, but at a minimum that means you'll need two power supplies (one a 24v and the other at 12v for the bed). With a heated bed as large as the TAZ unit, th...

Re: Mini bed levelling seems to be offset in Y axis

Start by checking the print head -- see if it's loose (it shouldn't jiggle, although the entire print head will flex a bit on the rods). Next check the bed itself, and the Y-axis limit switch -- see if they move in the Y direction (the bearings will often allow a little shift in the X and vertical d...

Re: Discrepancy with Cura 2.3.23

If you won't have a lot of force on the gears, then what you probably want to do is to favor hardness over toughness -- it'll lower the overall friction of the system. I'd go for basic PLA filament for that. The price you pay is that alignment needs to be more precise (no flex in the gears), more no...

Re: Moving Mini with Enclosure

I've had very poor luck moving the Mini with any part of that enclosure attached to it, as can be seen by the repairs I've had to make to one of the side panels on my Printed Solid enclosure. So I'd say remove all of the enclosure before moving the printer. Actually, I've had poor luck in general wi...

Re: ABS Filament Issues

That looks a lot like damp filament. Does it make and sizzling or hissing and popping noises while it's printing the bad area? If so, it's likely that your filament has absorbed moisture from the air, and needs to be dried out (search for various solutions to do this, ranging from a food dehydrator ...
