Currently, for my printer profile in Simplify3D, I have 3 "Auto-Configure for Print Quality" sub-profile (that we can choose at the right of the material:
- Fast (with layer height of 0.3mm)
- Medium (with layer height of 0.2mm)
- High (with layer height of 0.3mm)
The parameter which varied with the "Print Qualatity" are :
- Layer height
- Top solid layers
- Bottom solid layers
- Skirt layer
- Infill percentage
- Support infil percentage
I would like to make the First layer height a parameter that can varied with the print quality. By exemple, for the medium quality, a layer height of 100% and for the high quality 200% (for the same man profile) : is there a way to do that ?
Currently, if I change the layer height on high quality, the parameter is also passed in medium and fast quality.
Thanks
The first layer height can be the same as the whole printing model however you can set different sizes and speeds; it is recommended that layer height should be 75 % or less than nozzle diameter, this means that for a nozzle of 0.4 mm the max height is 0.3 mm (if you are a master you can use higher dimensions)
The first layer with a height of 0.3 mm with a speed of 70 mm/s will have less adhesion than printing at 50 mm/s. Also the same height and speed of 70 mm/s at 210 °C will have more adhesion than at 195 °C. So printing at 195 °C with speed of 50 mm/s could have the same adhesion than 70 mm/s at 210 °C. This depends on the quality of your PLA
On my prints I have set the prints at 195 °C and 55 mm/s with a height of 0.20 mm, then the whole print uses the same temperature at 85 mm/s with 0.25 mm of layer height. With other PLA quality I have to set 210 °C first layer at 50 mm/s, and other layers at 200 °C with 70 mm/s. So adjustments are based temperature and speed once you have determined the smoothness of your prints
