Hi CNC Community - Great Forum - I'm new to posting here & newish to CNC (so please treat me gently !!)
I have acquired a Defiance CNC machine as a project, which is in great mechanical condition, but the control side is not working. The machine was probably one of the last before Defiance went under, and I understand it has never run for long without issues and has always been unstable (hence the condition).
I've managed to get all almost everything - spindle and tables to work, it just will not get past the initial toolchange homing sequence no matter how hard I try. All the sensors on the changer mechanism are working and trace back to the board OK, so my ignorant guess is that the PMAC program is a bit messed up, and I really do not want to try to understand the Delta Tau PMAC, it looks way too complicated for my brain capacity.
Anyway, as a project, and a steep learning curve, I intend to enjoy the coming winter months in an attempt to run it under EMC2 from a PC and retire the old on-board computer, DOS based Evolution software and PMAC, but keep everything as is from the opto board outwards.
The servos and controllers are all yaskawa, the spindle invertor is Saftronics. The encoders are on the leadscrews. There are a load more I/O connections, but they are all fairly logically put together and understandable.
SO, sorry for the preamble, but the real question is what is the best interface board between the PC and the machine with EMC2 for me to play with ?
Has anyone got any similar retrofit experience, or bad or good experience or recommendations on matching motion control boards with EMC2 for servos ?
