Calibrating the Nimble Sidewinder V2

Because of the gear ratio inside the Sidewinder V2, There are a lot more steps per millimeter than your usual number.

Note

Start with 1800 steps/mm with a 1.8deg stepper and 1/16 microstepping

The Sidewinder has a nice flat surface you can use to set the ruler on, when measuring the filament, simply place it on top of the “ears” of the breech block. Use a light coloured filament, place it in the breech, heat up the hot end and start the process.

• Measure 100 mm on the filament, by holding the filament against the ruler while the ruler stands on the breech block ears.
• Mark the distance with a permanent marker.
• Extrude 50 mm using the firmware controls.
• Measure the remaining length to the mark made.
• Calculate the new number of steps/mm using the following formula:

Note

New steps = current steps * 50/actual mm extruded (50 being the 50 mm of filament you wanted to extrude.)

• enter the new value in your firmware settings.
• Do the whole sequence again, to confirm that the steps per millimeter are now set correctly.
• if not, recalculate and re-confirm.

You have now set the extrusion rate of the Sidewinder correctly and have the nozzles set right. You can now start Using the Sidewinder.
