How did they do $80k worth of repairs without completely replacing the control system with something current? I think I would be contacting my attorney if they promised that you could run large files and have not delivered when spending that kind of money. Where abouts are you located? I have a large CNC router similar to a Komo (moving table/stationary gantry/multiple heads) and I replaced my controller for around $2500 with one that can do whatever fits on my hard-drive. They should have taken care of you already, but if you can't get your work done due to file size limits, it's always possible to update the electronics yourself (it's not as hard as you probably think). I found this item on eBay. 31 I believe its intended to mimic a tape reader enabling larger files. But I have heard that tape is also limited to 1000 lines. This may only be a temporary fix if at all. Does anyone have any experience with this?It varies a bit from controller to controller, and without the manual I can't say 100% for sure, but in most cases you will be limited to whatever the RS232 port is capable of doing. If you can drip feed, you can probably run a fairly good sized file. If the RS232 port is basically locked out, you may not be able to use it at all. I used to have a machine with a NUM 750F controller (similar level of industrial build to Fanuc, etc.) would only allow the RS232 port to transfer files into memory and had the drip feed function disabled. In order to unlock the drip feed function, I would have had to send the controller back to NUM and they would change it somehow to unlock that feature, but wanted several thousand $ to do so on a controller that was already 25 years old at the time. Point is, you could buy it and it could work, or you could buy it and it could be useless. Where abouts are you located?
