We just purchased an old Sheffield Cordax Discovery D-12. and it was working fine at the company that we bought it from and for few days it ran perfectly at our premises, all of a sudden the machine ran away and gave the error. We got an Mp-176 error. We clear the error but it still keeps returning. the weird thing is how the machine moves when we power the servos up. Video is included. and that is a code that comes on the board in the machine. Does that have any meaning??
Those D12 machines use a torsion spring for the Z-axis counterbalance - the type you find in a tape measure. Mabe the spring broke or the cable came loose. It has happened to me, but I can't remember what error it was giving me.
Also check that there are no covers rubbing. It is always nice to find that a problem is something simple like a loose/crooked cover. Though, you can normally hear when it is something wrong like that.
You might also consider greasing the linear guides. That may not be the problem, but since you bought the machine used, who knows how long it has been since that has been done. The carriages should have grease fittings on them. Sorry, but I don't know what type of grease you are supposed to use.
For troubleshooting, it might also help to E-stop the machine and move the axis' around by hand to see if there is any extra resistance or noises made when moving in certain areas. This is also a quick way to see if something is wrong with the Z counterbalance. Moving the quill up and down should take about the same amount of force.
