Hello, first of all congratulations for the content you are sharing, I have been able to see many things and learn from them. THANK YOU !! I just got a Kondia K600 machine with TNC155 control, I'm not a professional, it's a hobby and I'm fixing it and starting it up and one of the things I'm stuck with is that I can't load programs of more than 1000 lines... you could you help me ? I have seen in some video that there is a way to have a computer connected and run... but I don't like this option very much... would there be any possibility of expanding the RAM capacity?
Hi and sorry for the late response. I've read from some Heidenhain TNC1xx PDF manuals that the controller checks the available memory, but I'm uncertain that it could be upgraded (hard coded limit of 1000 lines per NC-program). On my spare TNC151 there are a lot of unpopulated ram "sockets" on the ram board, not sure what would happen if I populate them and add the companion TTL-logic to it. I use my TNC155 in dripfeed mode (no limit on how many lines of code) and I quite like it. I make my programs with altered Fusion360 post processor and use TNCCremo to send the file to the controller. It all works well enough for me. Once I made my NC-program on my main machine and saved it on a bad USB drive... Emergency stop was quickly pressed as the TNCCremo pushed some bad bytes through serial and TNC155 did not check the sanity of the code... Now I use the TNCCRemo directly and save my NC-programs to the same machine that is connected to TNC155.
I have bought some suitable RAM's from Aliexpress but at this point I have not tried to populate my spare TNC151 with more ram. There needs to be some more glue logic to handle it.
What the Fusion360 post processor likes to do is to make everything a tiny linear movement. That eats up quickly the program memory (1000 lines) No problem if one uses the drip feed but those kind of programs don't fit in the memory of TNC1xx controllers. Also tiny movements make the mill feel sluggish, which it isn't.
I have this ever going project going on to reverse engineer the whole TNC1xx controller and replace everything as a drop in replacement with modern components and a lot, a lot more computing power, but it all takes time as a one man show.😬
@@JyrkiKoivisto hank you very much for your answers!! It is a pleasure to contact someone who wants to help !! :-) Right now I'm postprocessing with Fusion360, and I've adapted the postprocessor to my Kondia milling machine from 1986, I use it as a hobby... I'm not a professional, I've had to do a lot of fixes and study manuals to get it up and running. . I also use the drip with the TNCRemo but that forces me to have a computer connected... I've seen your videos and they're amazing!! congratulations on the job. I don't know how to write you an email and thus avoid filling this video with comments...
