fI have revisited the fucking machine and decided to improve my latest model as much as possible. I am surprised at how good it is now. All the annoying little bits of stutter and hesitation are gone. I decided to dump the three knob encoder and replace it with an old fashioned analog version. Much much better. The new version has simple potentiometers to set the speed stroke and offset values. This interfaces with the joystick encoder much better and allows both to operate much more smoothly. Of course the code to run the new version is totally different. Right now, I only have a version for my cable “unstoppable” machine but adapting it to other machines is just a matter of setting a few limit variables to work with different motor to motion ratios. I will be posting details if anyone is interested as well as the new code.
