So, some folks have questions about how they can make certain changes in their prints. I will answer the most frequently asked questions below.
The following all apply to v1, v2, and v3 of Repetrel.
How do I change nozzle sizes?
There are two places where we consider nozzle size:
1. On the head, we use the number you have for nozzle diameter to make our flow calculations. See Flow Rate for details about how we determine how fast to spin the motor so that you get the proper volume per second of deposition. This image is for printing with a 14# (fourteen gauge, or 1.6mm ID) luer needle:
2. In the recipe, we use the extrusion width numbers to determine how far apart to place each bead of material. We expect your extrusion width to be 10% wider than your nozzle diameter (to allow for a nice sandbag-shaped cross section). This image is for printing with a 14# (fourteen gauge, or 1.6mm ID) luer needle:
This applies to everything we print, from PLA to Porcelain to PEEK.
Please note that we do NOT use any other variable relating to nozzle diameter. Not Bridge Flow Ratio. Not Nozzle Diameter. Not Extrusion Multiplier. All of these variables affect the E values in your gcode. Which we then ignore.
