Hello and thank you for choosing the Creatr for your printing needs.
In the following solution you will be instructed on how to calibrate the offset for your Creatr Dual hot ends.
If you can`t find the sticker with the offset values on the printer please install the firmware with the default values and then follow the steps below and adjust the hot end offsets.
1. The first step is to download the gcode you can find attached to this solution.
The gcode is set up so that each extruder will print a square. To calibrate the extruders you need to adjust the offset in the firmware so that both extruders print the square from exactly the same spot and make sure they overlap.
2. Once you download the gcode, connect the printer to Simplify3D and run the gcode. Make sure to use two different colors for each extruder this will make it easier to spot any deviation that has to be corrected.
3. After you run the gcode, disconnect the printer from Simplify and open Arduino 1.0.6 and load the firmware and start adjusting the offset until the two squares overlap.
How do you determine what needs to be adjusted? Please see the following image:
After running the gcode from Simplify you must disconnect the printer from Simplify before you adjust the offset in the firmware and try to upload it from Arduino so as not to have any errors.
Thank you for reading the solution and for any other issues please do not hesitate to contact our Leapfrog Support Team.
We wish you happy printing!
