Dear yellow shark,
thanks alot for your info. I am using ultimark 2 , I don't where to set the temprature in cura, do you know where to set the temprature?
As far as I kknow you set the temprature on the machine itself and if so, then how can that relation between layer height, print speed and extruder temp can exsit. I mean yes you are right there should be such relation but what would be that? is there any refrence say for ABS material?
thanks alot for your answer
Hi Cura does not calculate the print speed, you tell it what speed to use. OK I will stop there a sec. If you are using an "eazy" setting or whatever they are called, I have never used one, and you select "fast" I am assuming Cura uses a pre-set speed - maybe I am wrong and it does calculate.
But if you are setting the settings yourself with the basic and advanced tabs and the expert settings then the principle is as follows. You select your layer height and print speed and from this Cura calculates the volume of plastic per second (or whatever the time period is) to be extruded. What you also have to do is set the extruder temp. to ensure that for that given volume, the filament is molten/viscous enough to be able to be pushed through the nozzle. If it is not you will get under-extrusion. So you can see there is a relationship between layer height, print speed and extruder temp. You learn this by experience and by asking the Forum when it goes wrong! Some filaments can cope with a reasonable margin of error, say 10c+, some are quite sensitive and you need to get close. Also to get excellent results you need to get close too; a couple of degrees either way is probably OK but a 5 degree error could affect quality.
