Basically the Z Arduino driver will be interpreting the 5mm moves to a 360deg cycle on the motor, that's the logic I have tested, right now I only have one feedback on my Motor (optical sensor when the needle is up) but with my setup right now of only one feedback, I get inconsistencies on the needle position hence I'm planning to have 2 feedbacks, speed and position of the main motor so I can control the power being given to the Z drive.
Nice work! Do you have a video of it running? How long did it take to do that "G"? I did something similar to my sewing machine using a stepper to drive the sewing machine and have noticed that my NEMA23 can drive it but it is super slow compared to commercial Embroidery machines.Now am re-designing my Machine drive to use the internal motor but I will have to provide speed and Indexing feedback of the needle in order to run it properly.
What my design on the Z axis would be using another arduino to control the motor and accept the Step/Dir outputs from the main one, so that it would still be compatible with the inkstitch.
