I've had a nice week in the sun doing nothing but think about CNC(sad eh?) So having sorted out a speed issue with kind help from Jazz, I was presented with another problem. Severe vibration on the gantry axis. This was caused by loose bolts holding the rail to the rail support(these were from chai). So having stripped down my gantry completely and trying to tighten the offending bolts, this is what I found:




Nearly every bolt had been stripped during assembly in china. So were basically doing nothing. My bad for not checking first. But after having re-tapped the threads and properly putting in new bolts. Everything is hunky-dory again......Phew! Suppose you get what you pay for in this game. I really wish I had dumped a few extra hundred quid and gone for profiled rails though. Maybe Santa will will bring me some along with the new spindle Ive requested from him
