Oh Blimey I bought a CNC Lathe !!!!
vtsteam:
Well, 9 bits either way. Maybe it's just looking for the even parity. and character bit 8 is bothering. Fingers crossed it will work tomorrow. I like your persistence awemawson. :beer:
awemawson:
OK Parameters loaded into the controller :ddb: :ddb: :ddb:
I still have some odd handshake error on the RS232 as at 1200 baud (the preferred set up in the book) I was getting 'overrun errors', but slowing it right down to 300 baud the data is in and done: Phew that was a struggle.
Still need to get the parameters into the three rotary axis (Main Spindle, Opposing Spindle and Driven Tools) and also into the servo amplifiers (X - Tool In/Out, Z - Tool on long axis and V - Opposing spindle on long axis)
I suspect that some of the Input/Output cards aren't working, as it's reporting a 'Safety door open' alarm, but the microswitch for it is being triggered.
Loads more to discover about this mammoth, meanwhile just in case some other hapless fellow happens across this thread trying to get a TX-8F controller Initialised I'll attach a scan of the scruffy page that got me over the last hill:
vtsteam:
Good work! :thumbup:
awemawson:
Lots of things happening now!
I got in touch with the chap I got it from to see if he knew where that document came from, and he casually mentioned that he still had the Optical Tool Setter and Zero Tool and did I want it? YES PLEASE :thumbup: It matters not a jot that I had already acquired a 'scope tube with eye piece and objective lens to make one!
Here are pictures of it in the box, it's Zero Tool and mounted on the machine
awemawson:
... And yes he had a few possibilities for where that document came from. To cut a long story short, I am now in touch with the author of the document who has been able to give me lots of very useful information regarding hardware and firmware compatibility.
However he tells me that I cannot use the replacement 10 slot controller as he asserts that the Input /Output addresses don't correspond and I would need different firmware to re-address the various I/O cards.
So yesterday I re-built the 6 slot controller using what I knew to be good cards (prints in Traub speak) from the 10 slot. That little pesky battery backed RAM card is different between the two controllers - you remember I recently got one (MC462A) for the 10 slot that got me out of trouble, well now if I am to use the 6 slot it seems I need an MC465a - it's basically the same thing but sits on the system bus not the rom bus so not interchangeable. I actually have two of them, one which was original to the machine totally locks everything up and the machine will not boot, the other reports a 'bus error' and displays what looks to me to be a cpu register dump. With no card installed I'm back to the Z58 BRAM error - argh!
Some picture to hold your interest :wave:
