I just finished the 3 axis chopper board. The kit is very well made and includes clear instrctions. The performance is great. I replaced a l/r driver with this and went from 40 imp cutting and 60 ipm rpaids to 125 ipm cutting and 180 ipm rapids. I was able to move at 210 ipm but backed it down so I will not lose steps. I run the board in 1/8 mode with 2 degree 150 oz 1.4a 4.5 volt motors. coupleled to 5 tpi 5/8 ball screws.I use a 34 volt 20 amp linear power supply. You can see a pic of my router in the pictures section. I would recomend this to anyone who is comfortable soldering a kit togeater. |
