Hello,
I've got Hitachi Seiki HT20 SII CNC turning machine. Today I've tried to send some programs to memory via RS232. All works ok, so I cleared all the memory and tried to send longer program, about 560 lines (generated with CAM). And there is a problem, the memory is not enough for this program. It's a big problem for me, because I often turn complicated combinations of radius, and using CAM is only option. Moreover, I think 560 lines is not a long program, sometimes I use few thousands lines.

So the question is - is it possible to extend the memory? Or use some external?
Please help me
