Yes, i can only agree that cost of machine itself (i paid ~100.000 USD for it 1,5 years ago) makes all the previously mentioned cost positions look ridiculously small, but my business is doing so bad, that available cash flows are almost non-existent, so i am stuck with looking for creative solutions, not those that are provided by industrial manufacturers. That is why i have chosen EMC instead of new controlling system from MEFI (creator of previous DOS-based system) or any-one else. Another reason is that I have come to conclusion that building by myself is better from terms of maintenance and support. My machine was produced in Czech Republic. Both - hardware and software (controlling system). I have been trying to contact those companies with different questions on how to solve some problems - machine is not new and different issues sometimes come up. My experience - there is no such thing as customer service in that country. When i contacted manufacturer of servo drives and asked for specific settings, their guy promised "to do it tomorrow". When i called a week later to ask for the reason of delay, it turned out, that my guy is on holiday and his colleague explained that my guy [quote] "probably had more important things to do". Very similar is situation with PTV - manufacturer of the machine. There is no way to get some support from them, I have tried to contact them several times with questions about spare parts and how to do certain things in mechanics to improve accuracy. I have come to conclusion that some kind of retards are working there. So, returning to the essence of this discussion - how can i implement in EMC tangential tool control for tilting the head? Prefferably with A and B rotary axis :) Viesturs ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
