Here is a summary of what each item means in the setting menu and how it can impact Moai printing:
When you click setup from the main screen
it will take you to the main setting menu:
X Size and Y Size
Both have to deal with the size of the scanning area. This is where you adjust when your print size is different than the STL file. 90 is the default value, and when you increase the value, the scanning area for the X-axis expands.
X / Y axis in cura
X / Y axis on the printer
X Deviation and Y Deviation
Both have to do with the position of the scanning area. By increasing the X value, you will move toward to front side of the printer. By increasing the Y value, you will move toward to right side of the printer
These have a default value of 100. DO NOT ADJUST THESE TWO VALUES UNLESS your scan area is outside of the plate surface area. This should rarely happen, and you should contact us before changing any values here.
This deals the slight delay in which laser is firing. It will be removed from menu shortly and please ignore this value. The default value is 50.
Z Motor Speed
This deals with how fast the Z-Axis is moving. The default value is 30. There is little reason to change this value as it does not affect print quality.
PM Motor Speed
This has to do with how fast the vat is tilting at layer change. The faster PM Motor speed is, the stronger the force is applied to separating layers. Earlier Moais have a default value of 80 while newer Moais have a value of 65. 80 would work, but 65 should give nicer layer lines.
This takes you to the following menu:
This changes the laser power output level. 61 is the default value and works well with our Cura profiles and Peopoly resins. Higher value means higher laser power and vice versa for a lower value. A higher laser power means quicker curing and slightly larger laser spot size and vice versa for a lower value. The recommended way to figure out exposure settings for resin is to use our Cura profile for 100um layer height, set laser power down to 51 to use the ring gcode file to test. Increase laser power if the print fails to stick to the surface and decrease laser power if over-curing happens (The resulting ring have closed holes on the top and side and very loud popping noise during layer change). Once you find a laser power that works for test ring, our Cura profiles for all layers should work for this laser power setting for this resin.
When setting this value, please wear your protection glasses as the laser will fire and you can visually inspect as needed.
X/Y Speed Set
This deals with how laser and galvo work in conjunction. 4 is the default value, and please keep it there. Other values will likely not print at all and only cause headache for you.
Z Reset Position
This value defines how low the build plate moves down when printing the first layer. It is frequently used value for leveling. The default is 188. Leveling guide can be found here.
When you adjust this value and set it by double click. The build plate will drop down to the Z reset position you just set. This is needed for leveling. When you finish, just turn off the power and the build plate will go back to its default position.
PM Reset Position
This value defines how much the vat tilts. The higher the value, the longer distance the vat will move to separate the layers. Default is 100 and you can lower it to reduce separation force and increase overall print speed. It is not a frequently adjusted value.
This is another value that deals with layer separation. When the vat tilts during layer change, the build plate lowers slightly to help reduce separation force on each layer. The default value is 180 which translate to 1.8mm movement and works well. You could experiment it in conjunction with PM Reset Position.
