#Hemera retraction settings drivers
We have a guide on the VREF values for the most common stepper drivers on the market currently that can be found here:.In order for Hemera to operate effectively at the correct torque level. The Hemera stepper motor in all likelihood has a different current rating than the previous motor your printer was using.Check you have adjusted your VREF/ configured the correct amount of current the motor is being provided.
Also, make sure before you do the E steps Calibration that you have activated relative mode.ģ.If you are entering the E step value via Gcode make sure you are following up with an M500 command in order to ensure the new settings are being saved to the Eprom.In order to get an ideal step per mm value, you will need to fine-tune these settings, a 100mm extrusion test is the best method of doing this.Whilst we state an E-steps parameter of 409 steps per mm, be advised that this is based on a microstepping value of 1/16, if you are using a different microstepping value your E-steps value will be different.If you are not familiar with which settings you need to change please see: Firmware modification is not an optional step, in order for your Hemera unit to work effectively you must make the outlined firmware modifications.
Here are a few quick troubleshooting steps before contacting support in regards to issues you may be having with Hemera.
