Re: Support - anyone done the lion at thin layers yet? - 13 years ago
I suspect support needs to have some sort of 1 in 4 slope calculated into it or something.by se5a - Slic3r
Support - anyone done the lion at thin layers yet? - 13 years ago
I had a go at doing the lion (http://www.thingiverse.com/thing:7930) at .05 layerheight with support, this time the support was actually THERE which was great, unfortunately it was to small (just a single dot of extrusion) to be useful and came off the build plate after only a few layers. anyone else played with support yet?by se5a - Slic3r
Re: Jan's Hot End MK-II - 13 years ago
well my first attempt at making a hotend was a partial success, though it failed at the pfte-barrel join. used the same method Iceman uses here, but it extruded itself. I was using an 8mm rod (though would have been more 7.something after I'd filed the thread off it and put groves in it) going into a 20mm PTFE I used a 5mm hole and hammered the two parts into each other, then used a hose clamp.by se5a - General
Re: Stepper motors sure are complicated - 13 years ago
yeah those will draw a too much current for the typical setup (using pololu drivers)by se5a - General

Re: Is it possible to home just one or to axis every level? - 13 years ago
note that homing is probably not that accurate, and going to be a tiny bit different each time.by se5a - General
Re: Recycling HDPE plastic containers into filament - 13 years ago
if you could do a consistant 1x1 square section you might be able to get something working duno how well it would work once it got to the hotend, as I understand it the round filiment expands as it heats up blocking the hole in the ptfe and stopping backflow. another problem you're going to have with HDPE is it shrinks a lot as it cools. so it's not easy to print with.by se5a - General
Re: Moved to 0.3mm nozzle size - what software settings to change? - 13 years ago
you should only need to change it in slic3r or whatever. since extrusion steps is done on filament input rather than output.by se5a - General
Re: Hacks I'm not Proud of... - 13 years ago
Got one right here: focus is a little out, but I'm holding up some parts by placing bolt boxes next to them. while they print. Edit: fix sizeby se5a - General
Re: Idea for super smooth exterior surfaces after print wil it work? - 13 years ago
cyanoacrylate gives a nice shiny finish to PLA. applying it in a nice even layer could be tricky though.by se5a - General
Re: Prusa Mendel Power supply for Sanguinololu - 13 years ago
yeah that one is not going to cut it. you need something that will cope with waaay more current draw than that.by se5a - New Zealand RepRap User Group
Re: Cooling fan with RAMPS 1.4 - 13 years ago
somone in Australia sent it to me as a kit. umn Auzze maybe? I'll check if I can see if it says anything on the board the board says ultimaker ramps 1.4by se5a - General
Re: Cooling fan with RAMPS 1.4 - 13 years ago
I'm still in the same boat. keep us posted when you do find out what the problem is, and I'll do the same if I figure mine out. atm I'm just running with the fan always on and manualy placing the fan where it can blow on the part or not.by se5a - General
Re: Infils over empty space - slicing problem? - 13 years ago
Yeah I noticed this too, and even made a report on github which got closed, I wasn't able to be as clear as you as to what the problem was.by se5a - Slic3r
Re: Unnecessary retraction on Z move? - 13 years ago
think I may have fixed the blobbing, seems that the default acceleration settings were way too high. will print this object again and see how it comes out.by se5a - Slic3r
odd x/y flip? - 13 years ago
this is a little weird, could it be caused by an dodgy/noisy endstop? since it's only ever happened on the first layer, I'm thinking maybe not... still seems a little weird for an endstop to cause this. otherwise I'm thinking something with the firmware.by se5a - Firmware - experimental, borrowed, and future
Re: Odd problem with my Y axis travel. - 13 years ago
well if you swapped x and y that would have used a different pololu.by se5a - General
Re: What motors are better? - 13 years ago
It's better to look at the power output and current pull kthx says: ideal steppers are ideal steppers are NEMA17 size, rated 1.5A to 1.8A or less, 1-4 volts, 3 to 8 mH, 62oz.in (44Ncm, 4.4kg.cm) or more of torque, 1.8 or 0.9 degrees per step (200/400 steps/rev respectively), for example the kysan 1124090/42BYGH4803 or the 17HS8401 if all that is equal, then you're going to get more steps per mmby se5a - General
Re: Jan's Hot End MK-II - 13 years ago
if you want to test for strength, try extruding cold for a bit. then try printing onto of layers that have had too much fill. (so the hotend gets dragged through the layer below, which will cause it to flex side to side) if it can survive the above then I think you've won the prize for the best techniqueby se5a - General
Re: HELP! Brass Extruder Nozzle Rubbing on My Prints! - 13 years ago
yeah depending on your hotend, 205 is way high. I print PLA at 185 if you've calibrated your esteps that way they should be fairly close, have you also measured the diameter of your filament? measure it with a calliper in a couple of different places along the length, and also check whether it is round rather than oval average it out and use that number in slicer for the filament diameter. Iby se5a - General
Re: HELP! Brass Extruder Nozzle Rubbing on My Prints! - 13 years ago
try lowering the temperature a little, also try a fan blowing on the part. check your esteps too. print something with a couple of solid layers, after the third layer examine how it's printing, if there's too much try send an M92 Exxx ie if your esteps are currently say 700, send M92 E680 if your esteps are too low you'll start to notice slight gaps between the extrusionsby se5a - General
Re: Tangleball gets another RepRap - 13 years ago
oh yeah there's a bit of history, def get that up and running again.by se5a - General
Unnecessary retraction on Z move? - 13 years ago
slice and print the Twisted Bottle: at 0.2mm layer height it's fairly obvious at 0.1mm it's disastrous. when it gets to the bottle part, and it's not printing the lid as well any more, it stops, retracts, goes up a z level, extrudes and continues. at 0.2mm I get a little blob at this point at 0.1mm I get a large blob and had to stop the print it got so bad. the wait time at this point also cauby se5a - Slic3r

huh, interesting way to join the ptfe and threaded tube. I might have a go at that.by se5a - General
Re: Cooling fan with RAMPS 1.4 - 13 years ago
M107 does not work for me, on sprinter main or experimental. (the fan stays on)by se5a - General
Re: Slic3r and pronterface - 13 years ago
Just download the latest pronterface, it has slic3r included.by se5a - Slic3r
Re: Cooling fan with RAMPS 1.4 - 13 years ago
I also get the fan running contunuosly when plugged into d9 in ramps 1.4 I was suspecting a short somewhere, (soldered ramps up myself) but I can't see one anywhere obvious.by se5a - General
