1- To use Commercial Cruise controller amount ranges from 450~ 600 US dollars
2- To make a cheap encoder out of mouse wheel, install it on the sewing machine wheel, get the degree (Angle between Needle Insertion to needle comes at just top of the hole) and use this feedback in our postprocessor...This will ensure that the X-Y movement of the table will only happen if the Needle is outside of the hole.
3- Remove the Machine motor and replace it with a stepper motor.
As this project is DIY and low cost so OPTION-1 is rejected... For Option-2 i will need help from the gurus here for producing a macro/postprocessor that move the table (X-Y) only when the needle is outside the hole..Its just the as of drilling operation...All the needle feedback will be recieved through the encoder..
Any Thoughts???
