Manual work on the machine continues as I had to make changes to the design. The ball bearings are now adjustable to minimize backlash in linear movement:

Creating a prototype for a simple to build machine is no easy task and it's not cheap, since you have to build many parts twice or even more often...

With the price money I have ordered a bunch of electronic parts. The first run will be done with the printer motors and sensors, but the frame will also be driven by bipolar stepper motors. The idea is to give you a wide variety of motors and sensors to make your own build. Making it easy for you means more work and money to spend for me, but time will tell if it is worth all the effort...
