Change speed and flow during printing

LDM printing, by its nature, involves working with mixtures that can vary from each other with different characteristics of consistency, humidity, homogeneity, rheology.
This requires greater flexibility in the printing process.

For this reason, WASP printers allow you to vary in real time significant values for the success of the process during printing.
Changing these values will change the reading of the gcode in progress (without changing it).
Changing the flow and speed values to print at their best is not to be considered a mistake or a “fallback” but is part of the fine-tuning of each dough and is therefore a recommended practice.

The main values that are changed to improve the process are:

FEEDRATE: During printing, you can turn the control knob to increase or decrease the speed in real time. This allows you to vary the print speed as the gcode runs. Here is some important information about speed adjustment:

  • The default value is usually set to 100%, which corresponds to the speed stated in the gcode.
  • Increasing the speed to 200% means that the gcode will run at twice the speed, while reducing it to 50% will mean that the gcode will run at half the speed.

It is important to note that changes in speed can indirectly affect flow proportionately.

FLOW: You can also adjust the flow while printing. Here’s how to do it:

  • Go to the Fit menu.
  • Select the “Flow” item.
  • Turn the dial to vary the flow value and confirm your selection.

The default value of the stream is usually set to 100%, which corresponds to the flow declared in the gcode. For example, setting the flow to 200% means that the extrusion speed will be doubled, while reducing it to 50% will halve it.

These options allow you to adapt the print in real-time to the specific needs of the material and body used, thus improving the printing process and achieving high-quality results.
