[QUOTE="Nena, post: 311009, member: 7861"] I use high precision steppers, but the Harmonic Drives are more precies; the motors have a encoder but i want one extra encoder on the shaft of the cutting head to position it exact while i use the Harmonic Drives. If the motors are running at 3000rpm the Harmonic Drive is running at 60rpm. I do not loos any steps but i can set the HD at a absolute position. These HD's cost about AUD $2500 eatch. The motors +/- AUD $300 each. I dont think any dust will come in the housing. The bearingholder will be vacuumshut and the complete housing will i do wil 12-22mm plate. And all plates are sunken into the other plate for straight building. [/QUOTE]
