    At the moment my 3m long ball screws in Fixed/Fixed config are without a glitch. Though as i said somewhere, when i start machining very fast like more than 12m/min then the rotating nuts start to heat and heat the screws. I think the fact that the gantry is ~200kg and moves with such high acceleration plus the speed , helps that. Which is cured by additional greasing prior to that. Otherwise no problems till now.

    I think one of the biggest problems when DIYcnc is not locking the bolts with a thread locker. Now i lock any bolt on a machine. Not only the obvious that need that. That is also valid for the shafts and the pulleys. A must do , i would say.
