I'm completely lost ...
I continue to have trouble drip feeding my Heidenhain 151B. Note that I have no problem communicating from PC to controller, and vice-versa, when the controller / TNCServer on the PC are configured as follows:
* Heidenhain 151B controller is set to EXT mode (baud rate has always been set to 2400)
* TNCServer (running on PC) is set to FE (see attached picture of TNCServer set to FE mode)
* Machine Parameter:
M71: 515
MP218: 17736
MP219: 16712
MP220: 279
MP221: 5382
MP222: 168
MP223: 1
MP224: 4
Also, I have no trouble communicating when both the Heidenhain controller and TNCServer are both in ME mode.
My symptoms are that I get a "BLOCK FORMAT INCORRECT" error (see attached picture) when drip feeding a large program, screen says TRANSFER BLOCKWISE, a large program. Specifically it gives this error on line 1221 every single time regardless of whether I am running the program during transfer or not.
Running a program of less than 1221 lines behaves fabulously.
From reading other posts, I see that the Heidenhain controller should be set to FE mode. When I do this, the TNCServer simply says "stopped" as soon as I attempt to either upload, from the PC running TNCServer, or download from the Heidenhain controller. In other words, FE mode (reached by pressing the MOD key) on the Heidenhain controller doesn't seem to work.
What in the world is it doing? What should it do? What should I do to drip feed this (and other) large programs?
Thanks again!
