Well, i'm getting pretty decent 1st layers it seems and i did another one of those hollow cube prints with 2. and besides a lot of people are printing with. Ps i also tried raising and lowering the global z offset +0.04mm and -0.04mm which REALLY cuts it close if in fact my feeler gauge is. i guess what i'm looking for like you said is to find the one or two settings i can always change or look at first, then move on to the next thing if needed. So that's when i started wondering about changing the extrusion multiplier and if that's a good thing or bad thing. I did also try 5 degree increases in temperatures up to 210 anything above that the pla gets pretty goopy and stringy. but i did try multiplier of 1.00 and set my esteps 107steps/mm and my 1st layer actually turned out well. 9 to 1.05 to see if the 1st layers were any better and they weren't so maybe i needed to go more than 1.05. I did try changing the extrusion multiplier from. 06mm from the surface and i have mesh bed leveling with marlin turned on and set it manually with that same gap using a feeler gauge. That's what has lead me here - i know my nozzle is just about perfect (?!) gap. the brims/skirts are always guitar strings! there are gaps between the lines it lays down as bottom solid infill. Ok, so my first layers since getting simplif圓d have always been questionable. and at what speed - does that make a difference? i know my printer came with a preset extrusion steps just like the xy and z axis movement steps. However then i tested the extrusion of 100mm of filament - but even in that there are variables - i assumed the best approach was through the nozzle at a certain temp. ![]() So yeah, calibrating esteps on xy and z seemed really crazy to me because wouldn't the mfg of the printer know that already and program that into the software?! i mean, it's visible right there in my config.h file and on the printer's control box interface. so this is why i'm just starting to now understand things - i'm making one change at a time and then printing ha! Of course, what I've said here is purely my own opinion based on my six years of 3D printing. Then only change one setting at a time when trying to tune your settings. The same would go for the esteps for the filament feed.you might as well drill the nozzle out with a larger drill as an alternative to changing the esteps!!īottom line.learn what the slicer settings actually do.and what the effect of changing them has. You are essentially adjusting the x, y or z mechanical dimensions of the bed in relation to the dimensions the slicer thinks the bed is. Tweaking the esteps is totally unnecessary.and in fact I would say is a really silly thing to do. My experience of filament has shown that the diameter of the filament I use is very, very consistent.and consequently, once I have settings tuned, I never have need to adjust either of these two settings.even on changing rolls and/or colour. Thinking technically about the extrusion multiplier.the value is used to adjust the overall calculation of the amount of plastic extruded throughout the whole extrusion process.and it is one of two values that do so.filament diameter being the other setting. Having said that, I only work in PLA and I always use plastic from one supplier. I have, however had on a few occasions needed to adjust the temperature.but purely to ensure a particularly complex or small part needs printing. I've never had cause to even think about changing the esteps. ![]() I've hardly had to make many changes to the extrusion multiplier. I tend to partially.but not completely agree with this. I also wonder if extrusion multiplier affects overall layer height, or setting higher esteps for that matter? so over time and height in a tall print the errors could add up and not be good! although is there some thoughts on using a bit larger nozzle size in the slicer? 4mm and i have its size set to manual and. 84 on all 4 sides - it's consistent great! my nozzle is. 9 extrusion multiplier and 107 esteps which i judged by the many 1st layer tests i've done. 9 for pla and my machine profile is OK? it seems like you can fudge it between esteps and extrusion multiplier?Īs far as temps, i see that makes a big difference too, but not as much as extrusion multiplier or esteps. In otherwords, maybe setting the esteps and leaving the extrusion multiplier set to the default of. i do this under the scripts tab in the start gcode.Īlso, should i set extrusion multiplier to 1.0 when i am using the esteps? i used the macihne control panel to extrude the 100mm of filament so not sure if that took into account the extrusion multiplier? i started getting pretty great results with the esteps cranked up above what i had calibrated, i calibrated from default of 95 to 103, but then turned up to 107. I'm beginning to understand that extrusion multiplier, esteps and temperature are really tightly related! i have done a ton of 1st layer tests.
