Your fellow machinist is in trouble my friends, so I have been practicing machining some 3d profile; I using steroform as my material and trying to machine simple 3d geometrical shapes like pyramids, cones etc. So I have tried machining this pyramid cone file a couple of times; 4 times specifically. I have succeeded only one time with no mistakes, and other 3 times with a simple error cut on the top of the cone.(@ different place every time neither the same size or lenght).
In your opinion what could be causing this:
Some other information that might be helpful
; My zaxis was behaving badly prior to this and the motor usually slows down while I was machining and lose its positioning, while the other two axis worked fine. Thus resulting in improper cuts on a big scale. I have got a new driver for z axis; but seems like the problem has only been minimized to a very large extent. Expect these small mistakes that the machine is making.
Also was running at 45000 kernel speed which took me to 250 to 300ipm @medium accelration, the for the step pulse & dir pulse i got [1 - 0] for all axis (don't know what that means).
I have took the kernel speed back to 25000 and machined @ 225 ipm for the last piece i machine, but still got a error in the machining piece (a small cut at the top).
Z axis mechanically seems to running fine.
