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.
