Anemometer - 11 years ago
Hello, As I'm about to mount my sun blinds¹, I need an anemometer to protect them from wind (they will be automatically raised when the wind reaches a pre-defined speed). And I was wondering if I could not build my own wind sensor, as a classic anemometer... Does anyone as already done somthing in this way? I don't know yet if I will do it entirely printed, or if I make a mix of printed partsby fma - Let's design something! (I've got an idea ...)

Re: Feature request - 11 years ago
Michel, this is possible (and I often do it) with EMC2...by fma - Slic3r

Which app. do you use to see the gcode like that? This is nice!by fma - Slic3r

In fact, dimensions increase a little bit with the speed... Don't understand why.by fma - Printing
Printing issues at different speeds - 11 years ago
Hi, During solid fill layers, changing the speed has a strange effect: higher speeds seems to put more ABS than lower speeds. My 'normal' speed is 40mm/s. If I increase it to 60mm/s, I notice that the filament goes too far on the perimeter, and also put a kind of blob when reverting the direction. This leads to a higher layer at both ends. Decreasing the speed to 25mm/s gives me much better resuby fma - Printing
Re: G Code for Extruder Retract - 11 years ago
Just reset the E axis: G92 E0 and move it backward: G1 E-2 F1800 (here, 2mm, at 30mm/s).by fma - Slic3r
Re: Converting Slic3r Gcode to suit EMC - 11 years ago
Something like: #!/usr/bin/env python # gcode2ngc.py import sys # First line print "%" f = file(sys.argv[1]) for line in f: # Change extruder axis name line = line.replace(" E", " A") # S -> P line = line.replace(" S", " P") # Comment M82 code line = line.replace("M82", ";M82") print line.strip() # Last line print "%" should work.by fma - Slic3r

Great! Thanks for sharing all these tips and tricks!!!by fma - Slic3r
Re: Converting Slic3r Gcode to suit EMC - 11 years ago
A better way is to let Slic3r use E as extruder - it will allow you to load gcode file in other tools (viewers) - and to write a filter. It will also convert from .gcode extension to .ngc. I use this filter: #!/usr/bin/env python # gcode2ngc.py import sys # First line print "%" f = file(sys.argv[1]) for line in f: print line.replace(" E", " U").strip() # Last line print "%" To enableby fma - Slic3r
Re: feature proposal, set time of print instead of speed - 11 years ago
Another solution is to use emc2: it has a slider to increase/decrease the global speed. Very usefull for small layers, or, as you say, when it's time to sleep! I use that feature very often. Maybe this could be implemented in dedicated hardwares, through a little jog?by fma - Slic3r
Re: First try with Slic3r - what settings to use for Orca 0.2 - 11 years ago
And for a 0.5mm nozzle, what is the maximum layer height?by fma - Slic3r
Re: Printing strong objects - 11 years ago
Thank you both for these informations. So, I have some space between 220°C (and not 250°C, as I said in my first post) and the maximum usable!by fma - Printing
Re: Printing strong objects - 11 years ago
Thanks! How high can I increase the temperature, for ABS?by fma - Printing
Printing strong objects - 11 years ago
Hi, I'm wondering how to tune parameters (mostly temperature and speed) to print strong objects (ABS)? I often have problems between layers, which do not stick really well under load. I'm printing @220°C (not 250°C as I first said), perimeters @30mm/s, infill @60mm/s... Thanks for any tips.by fma - Printing
Re: Minimum Travel after retraction - 11 years ago
I think that Slic3r does not retract filament if the travel is less than this param...by fma - Slic3r

Re: Slic3r 0.5.7 - 11 years ago
I just printed a thing I designed, and it is really nice! This release is really good, and could be called 1.0. Congratulation, this is great job. Thanks for making such powerfull tool!by fma - Slic3r
Slic3r 0.5.6 - 11 years ago
Hello, I tried the new release of Slic3r, yesterday night, and found that the solid infill is not as good as before: there is too much gap between filaments, leading to a very sparse surface. It seems to be worse when the infill direction is not 0 degrees...by fma - Slic3r
Re: Installing Slic3r - 11 years ago
Just download the latest release from here: or or unpack the archive anywhere you want, and launch the executable from the bin/ dir.by fma - Slic3r
Re: 'skirt' feature - 11 years ago
I think G28 is OK. The problem is about vocabulary: home # reference...by fma - Slic3r
Re: 'Cool' feature - 11 years ago
Ok, I see! I will give it a try to see if it gives good results. Thanks for the tip.by fma - Slic3r
Re: 'Cool' feature - 11 years ago
I don't see any temperature related to the smal layers, in skeinforge... What param are your refering? Does the filament stick well if you lower the temperature?by fma - Slic3r
Re: 'skirt' feature - 11 years ago
Yes, my homing position is in the center of the print bed. This is easier to check if the object fits (I only have a small hot-bed, for now).by fma - Slic3r
Re: Slic3r is cool so far - 11 years ago
I will also try the 'lift Z' param, to see if it reduces the problem...by fma - Slic3r
'skirt' feature - 11 years ago
Slic3r first moves down the hot-end to the first layer Z value, then moves to the XY location. I think it would be better to first move to XY location, *then* to go down to the first laye Z valuer. This will avoid the little blob in the middle of the print area...by fma - Slic3r
