To resume an interrupted print, it is necessary to load the area “Press” the gcode of the print in question. Once this is done, you need to physically measure in millimeters the height from the printing surface of the point where the printing was interrupted. Once measured in the area “Press” you have to click on the item “Resume Z print”.

In the window that appears you have to enter in “PosZ measured” the height of the object so far printed and previously measured, and then click on “Calculate”. In “PosZ where to start printing” it is necessary to select from which of the proposed heights to start printing again.
Once this is done, click on process and then click on "Start print" in the Print area.

Our advice is to equip your 3d printer, with the end of thread sensor.
This sensor automatically stops printing, and you can pick it up exactly from the point of interruption.
