  1. I Still don't understand this method. How can you measure the length of filament pushed by the extruder by measuring it on the print bed once it's printed?
  2. How do you measure 50µm filament length? I mean, how can you take such precise measure from the entrace of extruder to a given length of filament? I use the caliper and a pencil but the trace of pencil is larger than 50µm.. You mean movement of the extruder? Nice point! I never thought about it.. But I think that if you change your nozzle diameter you obtain something similar to change your filament diameter.. I mean, if you tell Cura that you want to print a .40mm wall with a .44 nozzle you are saying Cura to lower the filament extrusion, and this is similar to tell Cura to print with a larger filament, isn't it? Wow! Madness ;)
  3. What I usually do is set the correct filament extrusion length and steps/mm measuring with a caliper the length of filament extruded by the machine at printing temperature. When I'm sure that when I tel my printer to extrude 100mm it extrudes 100 mm with less than 1 mm error I save my steps/mm into eeprom so these will be my correct steps/mm for that particular extruder for all my filaments. Then with a given spool of material, exmple PLA 1,75mm orange, I perform a thin wall calibration, that is a cube with single wall shell @known wall line width (ex 0.4mm) no infill and . If with these settings I obtain a wall 0.44mm thick I'm in overextrusion and I assume that this kind of filament is alwais printing like this if I don't correct with flow or filament diameter or extrusion multiplier or whatever it is called. So in this particular case 0.40/0.44 is 0.91 extrusion multiplier in S3D word or 91% flow in cura. In my case using Cura I correct the filament diameter (1.75mm) in material management that is the opposite (0.44/0.40)*1.75mm=1.92mm Are these wrong settings for you?
  4. Yes, but as I said above that works on profile level. What I mean by multiplier is something relative to material (filament) setting. Let's say a given kind of filament always overextrudes. It is more reasonable to have an "extrusion multiplier" at filament setup level not at profile level. What I usually do, after fine tuning steps/mm for the extruder, is to print a sigle wall/well know thickness hollow cube, I measure and compare what I set as wall thickness and what my printer executes. With this I have a ratio between the real and desired thickness, that is an extrusion multiplier. This is good for a given kind of filament printed at a given temperature with a given speed, but I'm lazy so I consider it for my filament @print temperature. Then in S3D I used this ratio that is coupled with a given filament. In Cura there is not this option, so I change filament diameter, that is the same.
  5. Yes but that works on profile level. What I mean by multiplier is something relative to material (filament) setting. Anyway if you change the filament diameter in filament settings you achieve the same result as a multiplier variable
  6. System specs for you? I'll try with my sister macbook air as she will come and see me. It's last year model..
  7. The problem was with both mac os el capitain and high sierra. So I think much of the problems are by cura itself.. It's a pity. I'll get stuck with Idea Maker Thanks Pietro
  8. The problem for me is after program charging. Any click on GUI halt cura for at least 7/10 seconds Each time. Then layer view is almost unresponsive. 🤐 What happened after 3.4.1? That is the last version that is working fine I saw that development moved to a newer version of QT. Could this be the problem?
  9. In my case I just installed osx high sierra. All other slicers are working fine (S3d, idea maker, Slic3r PE etc.)
  10. I can confirm, cura starting from 3.5 version is unusable on macbook air 2011. I just installed the 3.4.1 version and it's a lot better. Normal cpu usage during slicing and rotating view specially in layer view.
  11. Hello Cura 3.6 is unusable on a macbook air 2011 I5 1.7Ghz 4GB RAM 256GBSSD with mac os high sierra just freshly installed.In Solid view if I don't do anyting CPU stays at 3-4%. As I click anywhere it jumps @150% making any selection/option really slow.In layer view once the stl is sliced CPU is 120% all the time. This was also for cura 3.5.x In 3.4 I think it was better
  12. Hello @Deneteus I just downloaded and installed Cura 3.5 Now I'm using Ideamaker as my preferred slicer I tried to slice the same stl with the same settings where possible Ideamaker makes my gcode 47600 lines while Cura 3.5 makes a 68600 lines one. I like the way Ideamaker slices my stl and travels/movements seem to be ok I must check what this new Cura version makes but the gcode volume seems to be a little too much..Bie
  13. Hello after the release of Cura 3.4 I tried another shoot. I attach gcodes for the same stl, two pieces in a single build plate. I made slicing settings as similar as possible (wall thicness/lines, top bottom layers, infill percentace/pattern etc.) Cura gives me 7.24 h print time, S3D 4.32 h If you open both Gcodes with notepad++ you can see cura's one is 343272 lines while the one generated by S3D is 138115 (less than half)... Is this normal? Thanks Pietro gcodes.zip
