Brett,
I use .005 as the value for my lathe and personaly never had a problem. It was probabaly back a year ago that ya'all mentioned that it affected the speed at which the backlash will be implemented.
This problem came to light when two frends were having problems with the their backlash and described the axis
movement ( of course i said, what?, no way) but once we got playing with the settings the problem surfaced
then the nature of it was understood to some degree. So still curiuos i duplicated it today at home.
What can happen to the unknowing, is that if they use some random Shuttle Accel value, and gradualy work their way down to a faster speed, like 10 down to one and happen to hit a range of numbers that cause a problem,
then good grief, hours later they don't know what the heck is wrong. Just imagine coupling this with say the curent threading problem yet to be addressed and you would need to have a crystal ball to to even explain what
what's happening.
I quess until it gets addressed, folks should just make note of what is posted here, and don't use a value like 5, .5,.6, or some range around those and make sure that they are not skipping steps.
If your using the SS, since it dosen't have backlash implemented yet, all this would be transparent
/ you wouldn't even be aware of the problem.
Good that your trying on the mill since maybe it's only a problem with MachTurn. Don't know.
