Hi Hood,
Thats correct, but I still need to 'throw' the 'close to run' relay to energise the spindle in either direction. I agree that I could have M4 as a valid output linked to the reversing relay, and M3 to a phantom output, say 57 or 91 etc, but I still can't 'close to run'
Hi Angel tech,
The Triac is a very early model with the electronics underneath. In fact, well probably, it is the very first Triac ever to have an ATC as the tool changer control has serial number 001.
I have moved the electronics into a seperate wall mounted enclosure, away from any nasty coolant, made various circuit boards, all fully opto-isolated, for datums & overtravels, step & direction, two lots of output relay boards, each with 5 relays, and am curently working on a board for the inputs. All of this is for the fun of it as I have no use for the machine when it's done ...the rebuild is the hobby and I have had to learn about everything i've done at every step as i have no electronics training. So, for example, when doing the boards i had to learn not only about optoisolators, transistors, and Zener diodes, and the correct choice of resistors for each choice of these items, but also how to produce pcbs using Circuit Wizard and Press n Peel paper which forced me into picking up a clothes iron for the first time in my 42 years ...very scary!
Just out of interest I checked back on the Denford forum and my first post, asking whether I should buy the machine or not was posted on the 16th November 2006. Sad or what?
http://www.denfordata.com/bb/viewtopic.php?f=47&t=553I have been a member of this site since buying the Triac and everytime I have asked for assistance it has been provided freely and willingly, and I have never been asked for anything in return. So, sincere thanks to everyone who has helped me so far, and hopefully I will be also be able to repay the favours to any Triac newbies out there. Please remember though, my comments are experiences not expertise.
