We often get asked how we calculate our flow rate.
The flow rate is calculated based on the following parameters:
- Nozzle (extrusion) width, as specified on the head (or, optionally, in gcode); should match the extrusion width in your recipe and gcode.
- Layer thickness (height), as specified in your gcode. Width times Height tells us the Cross Section of your print path.
- X/Y/Z distance to move from current position, as specified in your gcode. Cross Section times Distance tells us the Volume to be printed this move.
- Print speed, as specified in your gcode. Volume divided by print speed tells us how many nl per second to dispense.
- Pulses/nl, as specified on the head (or, optionally, in gcode). Pulses/nl times nl/second tells us how many pulses per second to dispense.
- Feed Rate %, as specified on the head (or, optionally, in gcode). Feed Rate % is a direct modifier of your other calculations; 1.00 = no modification; 0.90 means 10% less flow, etc.
