Hi, I am planning to convert an Emco Unimat PC (the last of the Unimats that also has stepper mounts). I have bought the original Emco shaft encoder for the main drive (5volt optical sensor) and was planning to also buy the original Emco CNC conversion kit (still available for about 820€, although it is almost 20 years old). However I am now thinking of instead going for a more flexible set-up with Mach3. I therefore, search advise on:
1. Were to find low-height steppers. They need to have a torque of 20 oz inch and can not be much bigger than 60mm in diameter and 30mm in height. Any tip on were to find such steppers in Europe is appreciated.
2. Advise on driver boards for these steppers. I need a portable compact solution (my kitchen-table is my workshop...). I was thinking of HobbyCNC or the cheap eBay DB6560´s - but after reading about the 6560's it seems that they are a no-go. Other advises?
3. How do I hook up my shaft encoder, is it possible to use the homing pins/function, in for example the HobbyCNC board?
For those not familiar with this Unimat, more info is available at:
