question , i,m using a simple trick to go on after fail with printing after ouhrs. 8 out of 10 time,s it go,s quit good ,and no los of my ouhrs printing . got a hal sensor part for the filament , when stuck ore not delivering filament after a adjustible time , it take with the webcam a pic from my cura from the pc screen and stop the 3d printer with printing . im reading the height that it has printed , into cura i save the g- code and open it with words and go to the height point where it whas left . i copy it and make a new g-code prog . then i start the printer again , you need a 100% solid end stop , no wakkeling ore half loose micro switch , this way you get the starting point real good again . starting the printer with only the first layer to print with a 25% speed to flatten nice the top from the last layer, it smooth out more the printing and getting a little thicknis here and there, but always better then lost a 20 ouhrs print . my question then now , is there a simpler way to go on when print is failing ? is it a option for cura to ad a plugin for...... , start from line nr ore layer nr ....... ????
