Try this in start G-code: M104 S ; set extruder temp M190 S ; set bed temp & wait M109 S ; wait for extruder temp Also read the tooltip for start G-code - if slicer detects M104 or M190, it does not generate any default temperature setting G-code.by ledvinap - Slic3r
Pri tisku ABS na vyhrivane sklo jsem zkusil pouzit Hercules (http://lepidlo.heureka.cz/lepidlo-herkules-30g/ , predpokladam, ze hlavni slozka je PVA) a zatim je to to nejlepsi, co jsem potkal. Sklo mam zdrsnene smirkovym papirem (asi to neni treba), lepidlo zastudena rozetru po skle do tenke vrstvy (zatim bez redeni). Podlozka ma 120C na spodni strane, na skle bude tak 90C, ABS tisknu pri 230C. Vby ledvinap - Novinky, nápady, nová řešení
Quoteradus QuoteRalf AFAIK nozzle diameter in Slic3r is only used to figure out extrusion widths. So if you set your extrusion widths manually anyway, you should be good, if you just set set your nozzle diameter to 1mm. NO! you a wrong. nozzle diameter used for calculate dimensions of model. My cube is 10x10 mm. If set nozzle diameter to 1mm then makes 0.5*diameter offset from edges of cube. Andby ledvinap - Slic3r

The problem is probably with 'avoid crossing perimeters'. Older algorithm does build visibility graph for layer from all vertices in layer (test all possible lines between vertices and build graph from all lines that do not cross perimeter) This is probably O(n^3) complexity (if all edges are tested in visibility test). Then dijkstra is used to find path in this graph. New algorithm does reduceby ledvinap - Slic3r

the Z or ZZ or -2Z suffix means that bearing is fitted with shield (http://www.skf.com/group/products/bearings-units-housings/ball-bearings/deep-groove-ball-bearings/single-row-deep-groove-ball-bearings/sealed-bearings/bearings-with-shields/index.html).

Hlavni problem je, ze slicer pocita s tim ze Z=0 je vyska stolu (tryska se stolu dotyka). Ty tam mas 0.1mm papiru, takze to nesedi. A slic3r podle tloustky prvni vrstvy pocita i mnozstvi plastu, takze ti zmena nepomuze. Pro nastaveni vzdalenosti trysky je lepsi pouzit nejaky presny valecek (treba 3mm tycku z CD mechaniky nebo nejake lozisko). Pak se najede tak, aby valecek prave sel protahnout poby ledvinap - Problémy
Maybe the bearing pushing filament against hobbed bolt could be the cause, but the ratio of rotation should be lower. Another possibility is problem with gearing - there is long period before same teeth meet (11 turns of big gear), this could explain long period of the problem.by ledvinap - Mendel90

You should probably post some photos of machine and belts. Maybe there is some problem with assembly.by ledvinap - Mendel90
Don't worry about Z travel time - it's a little bit annoying when first playing with machine, but you get used to it very fast. And as nophead said, the machine is heating up anyway during the travel.by ledvinap - Mendel90
Optical sensing is probably too complicated. Capacitive methods (http://www.google.com/patents/US4706014) can give direct cross-section measurement. Modern CDC (http://www.analog.com/en/analog-to-digital-converters/capacitance-to-digital-converters/products/index.html) should make this kind of measurement quite easy.by ledvinap - Controllers
If X and Y limits are 1mm outside of soft limits in firmware (I use same position in my version), then it explains perfectly described behavior.by ledvinap - Mendel90
The Z move after home is caused by Z soft limit being lower than home position. After first move the target position is clipped to soft limits so Z must move back a bit.by ledvinap - Mendel90
