Marchant Dice router no thrust bearings?

[gavztheouch]

Hi Web Goblin,

If you grab the ballscrew by hand can you get any play in it by trying to move towards and away from the stepper?

Yes lots, prob over a mm. :(

If the shaft is bent and directly affecting the stepper then it will eventually knacker up the stepper motor as well.

I know its only a matter of time before it knackers the motor. I actually completely rebuilt the machine last week, had the ball screw in the lathe to check the runout on the ends, straighten it out as best I could. A new coupler would help matters as most of the runout is in the coupler. Actually I thought to myself Ill get some oldham couplers, then I relised I couldn't because the coupler needs to be ridged to work as the motor is holding the screw in place, pretty crap huh.

I know merchant sell multiple routers like this a week I find it stange that they don't support their ballscrews. If they did I think they would have quite a nice product
