Jimbo, and at least one more, shared chopper's IP address. They have all been shut down.

On page one it was mentioned that if your using backlash compensation in Mach it could perhaps lead to these errors. chopper never cooled down long enough to see the post or say if he used the backlash setting in Mach or not. Mach surely couldnt get it right every time, different cut paths and so forth. Just guessing here but it does seem like he is pushing things to hard/fast on his table. Perhaps the torque curves of his new motors/belts come closer to "his" ideal cut force/speed.
Coming from someone who has the 7.2's/30pinion (all still new not in action yet) I am once again concerned about my motor choice. Because they are still new Im thinking of getting 20 pinion now. Gerald wondered if maybe the 30's were putting to large of a load on the gearboxes with the weight of the MM gantry.
So maybe.... *crossing fingers* if I break them in with 20's they might last longer? Who knows we shall see.
BTW backlash does not accumulate. *had too...*

Hay now, lets beat this dead horse.:D I think there's a easy to understand explanation using our virtual machines as an example that illustrates how backlash works in reality.If instead of .0005 backlash, lets just use a whole number as the example,say 1cm for the metric people.
In this model, we home the machine at 0,0, we then send the x-axis to 30cm.
The dro reads 30,but the bit indicates 29 because of the loss due to 1cm BL.
Now we send the x-axis back to 10 -- the dro reads 10, and now the bit is at 10.
The action back and forth of the x axis is backlash, followed by correction each and every time. It is the same for all three axis.Chopper, I know you got booted:( but If your reading this,in order for your cumulative error theory to be correct you would have to debunk this simple principle first (not easy).I'm not piling on,nor am I a political person,In fact I was impressed with your build job--excellent.You have some good ideas, but the debate is won by weight of substance not by personality.

Ron, there is no merit in pursuing this "debate" here. The days of arguing whether the earth is flat or round are long over.
