Hood,
1 The whole morning I have been testing the lathe for real,, on some pieces of metal (don't know any specifications, its not to hard, that is all I know, could be steel 37).
Mach3 is so much better than my old program!
Sweat on the forehead. One mistake with the jog cycle. Made a 10mm step on the z-axis, and by mistake I also made just before on the x-axis.
So I tried to cut 10mm in one cut. The toolholder was not to tight, so it was pushed aside,,, the insert broke.
That leads to the question: is there a way of having different jog cycle steps for the z- and x-axis, so you will never use the one for the z-axis on the x-axis?
2 Also had i strange thing with a program wizard.
The program showed a F 42 value, but the feed read out showed it was in real 66 mm/min.
Could it be caused by the feed override which I did before on the manual screen? I think not, because for as far as I know, it is not possible to change the feedrate while a program is running.
3 Once I read on the forum (and I think it was your message) about the feed and speed values. Could you give me a guideline on this subject? I have been testing and trying, but it would be nice to have some sort of guideline on this. I know it depends on a lot of things like the construction of your lathe, the power of the steppers, the size of the toolholder and so on,,, but a rough guideline would be nice.
