How to build a great first layer The first layer for 3d printing is very important. With bad first layer, the whole printing will fail. Here are some tips may help us make better first layer. 1.   Build plate leveling    Keep a good distance between nozzles and build plate. Too close, the nozzle will scratch the plate; too far, the first layer won’t stick to plate. We could put an A4 paper on build plate, and then move the nozzle on it. Pull the paper out without damage the paper and strength. Test: print a model first to check if first layer is ok and if the print could be finished well. 2.   Set 5 ℃ higher for the first layer    Higher temperature will fully melt the filament and make it stickier. This helps the first layer stick to build plate well. Based on our experience, 5 ℃ would be good. 3.   Slow down the print speed     Slow printing speed will reduce the strings when nozzles extrude filament. We suggest 30%-50% of the normal speed.

ZLiftDistance: the lift height of Z axis, you could set the value at lift the mm value after printing. 2. Introduction 2.1 Grammar Operation calculate ： +, -, *, / Variable value is calculated by [[]] Final value is calculated by up-mentioned character with {} 2.2 Uplift process Uplift process: Gcode after every layer in resin setting. G1 Z{[[LayerPosition]]+[[ZLiftDistance]]/2} F80 [[WaitForDoneMessage]] G1 Z{[[LayerPosition]]+[[ZLiftDistance]]} F800 [[WaitForDoneMessage]] Notice: The meaning of first line is using F80 speed during the first 1/2 uplift distance. The meaning of third line is using F800 speed the following distance. 2.3 Descend process Descend process: Gcode before every layer in resin setting G1
