Bts-100 with tosnac 70m V 01_E1 is reading the program and trying to goto postion but seems to goto correct position 1 out of 3 times . Position is random after that and does not repeat itself according to the program. This condition happens on all 3 axis xyz. It would seem the machine is going to a safe positon and not doing as the program states. Any help or suggestions on this matter would be appreciated. Thank you for taking the time to read this.
