I've taken all the suggestion here and seem to be having more luck, now that I have also set the extrusion multiplier to 0.9 Not sure why a lower multiplier would give me better top surfaces, but it does. Not even sure why it needs to be dialed back by 10% since it was calibrated to the actual intake within 0.5% I'm speculating that artificially setting the nozzle diameter low also needed a coby RobA - Slic3r
I've tried all the suggestion in the forum here and have no love for slic3r with my 0.5 J-head. No matter what I do, I have filiment gaps.... Any suggestions? Please? Otherwise I guess I'll have to try skeinforge and give up on slic3r. -Rob A>by RobA - Slic3r
I'm having the exact same issue. Slic3r -> pronterface ->marlin ramps 1.2, sells mendel, wade's extruder, esteps calibrated hot 0.5mm jhead at 180 (185 first layer) 2.83mm PLA onto blue tape.

I'm using the same combination and made some observations: - In the marlin firmware on powerup, it assumes it is at 0,0,0. This means you can move in the + direction off this origin, but can move below it, even if you haven't hit limit switches. - The home buttons in pronterface (I'm using the experimental windows build) will move the printer into the -ve space until it hits the limit switches,by RobA - Reprappers
Follow-up on this thread- Same experience as Haywire with the hot end I bought there I've had it running for less than three months and have had a failure with the barrel coming loose from the PTFE and teh PTFE softening... Not an issue with the hot end build quality, just an issue with the design - I don;t think I'd buy that style again... -Rob A>by RobA - General

WD-40 is classed as a "light lubricant", and is great on small items like hinges, locks, and toys. On heavy or fast-moving parts, the lubricating power of WD-40 is minimal. WD-40 will actually strip away any existing lubricant and leave your parts dry– metal on metal. (The linked page at WD-40 states "WD-40 gets under dirt, grime and grease to clean" which means it degreases!) from Quoteby RobA - Printing

OK - I've disabled arcs (by removing the flag from the command line), but the gcode still looks funny, even with the latest 0.7.2 when I preview in pronterface. I don't have another viewer for gcode, as it won't display at all in Rby RobA - Slic3r

I have a few questions with slic3r. I'm using Pronterface + latest slic3r driving marlin firmware are on RAMPS1.2 board. Mendel (not prussa). Printing PLA through a 0.5mm nozzle. First Question - I've got everything calibrated as per various sites... but slic3r seems to keep the filament too far apart, so top surfaces end up with spaces between the filaments.

Found the source of my problem... The vertical plate on the x-carriage lower part (that the the x-carriage belt clamps bolt to) was broken, probably due to over-tightening. This was causing that part of the piece to both rub on the rear x rod causing drag, and the belt anchor to twist when the belt changed direction. You can see the break and the wear on this part here: I cut this block off,by RobA - Printing
Thanks for your reply, joerlane. I printed another circle piece (15mm diameter) on a square base so I could reference it better. I also noted the head travel was counterclockwise around the perimeter. A bit of analysis gives me the attached. To me, it looks like that when X axis reverses direction, the carriage stops moving for a bit, than catches back up again. My belt is tight, setscrew tiby RobA - Printing
I've built a mendel, ramps 1.2, using the latest marlin, slic3r, and pronterface.
