the motivation came out while googling printer hanging problem (mains switching noise or spike) but it turned out i was brought to this little nice blog...

so to test the limit, i made the model comparing to our "dime" and produce. i believe her report is now obsolete (1 year ago) or she hasnt made a good tuning or wrong material. if you happen to know her, i'll be glad if you can pass the word and ask her to update her blog. the picture tells the story... at some degree, imho, my reprap is better than $35K stratasys (no contest there) well dont get cocky, this is after hours of firmware, slic3r and material tuning. but also be aware that, this is not my best tuning i think, i dont like the free abs i got with the printer (as used in picture), the short free sample whitish filament that i also got earlier (now exhausted) is better. glossier and more consistent output and nice milky like similar to stratasys material in the picture. i made an order for PLA material wait and see and try. until then...
