@nophead Thanks for the feedback, I can see what you mean now about the Y axis, although with the extra 30mm there I may still get away with it (not that it's a big deal, I'll just see what works at build time). That's very interesting about the 3.3v load, I hadn't considered it might affect the 12v rail, think I'll investigate that when I come to build the Sturdy, presumably the theory is that aby plankton - Mendel90
So I built an i3 (box frame), and it's printing great (within it's limitations), and I learnt a lot from the process, however I have this recurring problem... Whenever I think of an improvement or upgrade for some aspect of the printer, I invariably end up saying to myself, "well that's how the Mendel90 already does it"... it's very frustrating. I always knew the i3 would be a stepping stoneby plankton - Mendel90
I think I may be onto something. I've only ever seen it on >= 90 degree direction changes, but it seemed too random for the majority of mechanical causes. So I wondered if it could be due to temperature (the filament not being flexible enough to keep up with the nozzle on sharp direction changes), I just tried another print increasing extrusion temperature by 5 degrees and this time there arby plankton - Printing
I'm getting what I can best describe as occasional filaments that don't follow the correct path when the nozzle changes direction, I often see them around the perimeter of holes, but it does seem to be whenever the head changes direction (but only occasionally, not all the time). I printed the small cog from a Wades extruder this evening (see attached photo) which I think shows the problem reasoby plankton - Printing
OK, answered my own question, in Sketchup STL export I had the tick box selected for "export selected geometry only" (left over from a previous print), but I hadn't selected any geometry, so this presumably resulted in an empty STL file (hence only 1K, untick that and problem solved. So presumably this is a minor bug in Slic3r that it crashes if you try to load an empty STL file.by plankton - Slic3r
Not sure if this is a bug in Slic3r, or a problem with the STL file exported from Sketchup, but I made this simple calibration piece with a round and a hex hole in both vertical and horizontal planes, and a 1mm gap between 2 walls (yes, my gaps and holes are currently coming out too small), if I load it into Slic3r the program just crashes (closes). Anyone else seen this behaviour, any ideas whaby plankton - Slic3r
I've just been through something similar on my new build (a Prusa i3 box variation, RAMPS 1.4 and cheap Chinese steppers), so I'll describe what I did to resolve it. Symptom I had was occasional missed steps on X and Y axis (though not usually both in same print), usually happened after some minutes (not at the very start of a print), and some small prints were able to complete without problems.by plankton - Reprappers
Has anybody tried PLA from this seller on eBay UK, he's half the price of any others? PLA on eBay UK At that price I'm almost tempted to try, but my printer's only been printing for 1 week, it's far too early to risk adding potentially poor quality filament into the equation.by plankton - Reprappers
Thanks for the suggestions, in the end I decided to try what I had (acetone, and 2 part epoxy)... with no success, but maybe this will help someone else. The acetone was painted into the split with a small artists paintbrush, the repair looked and felt solid within 15 minutes but I couldn't guess if it cured at the same rate internally. After 2.5 hours I got impatient and tried re-installing thby plankton - Reprappers
So after 5 weeks of building (and waiting for deliveries from China), my Prusa i3 boxframe was finally ready to print this week. Bed levelled, all axis moving smoothly and calibrated, print bed and J-Head heaters tested, so I tried to load the filament ready to calibrate the extruder... and I broke the extruder! Probably a typical beginners mistake, I didn't realise the filament had come out ofby plankton - Reprappers
