Today we’ll see Canvas basic slicer settings. 

Inside Project Settings you’ll find:

  • Layer Height;
  • First Layer Height (%); 

Layer Height

A layer has a height and thickness. It’s made thanks to various movements, that are coordinates written inside the Gcode. They define the 2D (X & Y) section of the object. 

Important: the layer height shall never be bigger than 3/4 of the nozzle. 

With a higher layer, we risk the delamination, which means some layers would not blend in together well. 

For example, with a 0.4 mm nozzle the layer height limit should be 0.3 mm. 

The higher your layer is, the more careful you have to be with the extrusion speed. 

What is the extrusion speed?

Good question. It doesn’t exist inside the slicer, but you can verify it yourself. By looking at the pulley that drags the filament, we can understand how much the engine turns and we can also estimate whether the printer finishes or not. 

For example, if the extrusion speed is too high, the printer will struggle with its work, because it undergoes too much effort. 

Instead, if the extrusion speed is correctly managed, the printer will work just fine. 

Create a Gcode, where the layer height is 0.2 mm and the speed is 50 mm/s. This is the limit speed a Hotend can bear. 

The temperature should be set according to the type of material, but keep in mind that if we set maximum speed, we should add another 15°. (PLA, set 230° instead of 210°) 

Here is why: the filament going throughout the nozzle faster than before needs to be more liquefied. 

The quality of the print depends on the layer height. The more the layer height is, the less the quality you have. 

The faster your print is, the lower quality your object is. 

For example, setting a 0,006 mm layer height means extremely high quality, but at the same time, the printing speed shall be really slow. 

Layer height does not affect mechanical performance nor heat resistance.

First layer 

When the printer starts, almost everyone leaves it be. It’s completely wrong! You should always check the first layer, it’s one of the most crucial parts. 

Keep it higher, like 120%, because it needs to be a little more abundant.
