Hi, just starting to get to grips with mach3 for both turn and mill. I have a boxford 15tcl converted by another guy called cncdoctor (cheers Jonathan) and it works fine up to a point as does my Sieg X3 cnc converted mill (thanks to spg tools Hinckley) but two questions....
1 It appears that mach3mill and mach 3turn interfere with each other when you try and run them on the same PC but controlling both the machines via a switch box. The steppings for whichever is started up first seem to stick; so I start mach3turn and the steppings are 407 for the x and 800 for the y but if I then start mach3mill the movement is wrong and it appears that it does not pick the steppings up correctly and as it is 800 on both x and y the x axis is out of step, conversely if i start them the other way the boxford is wrong. Why does not mach3 pick up the correct settings from the XML file. I am starting the program from the launcher?
2: In mach3turn the Strue speed readout seems very wrong. I have set the pulleys for the correct speeds (320 - 3000 rpm) and to be honest they look pretty good, however the Strue speed dro is stuck at ~350 rpm when running at 1000rpm spindle speed. I have tried changing the ratio but that just makes it stuck at some other arbitrary figure, for instance, if I set the ratio to 1 @1000 rpm then the Strue readout is ~60. What am i missing as I understand this is need for thread cutting.
Thanks for your help in this
Tony
