Denford Triac Euro Card, 2.1 Eprom or USB Rack card

**m_c** · 14-12-2016

I've just seen your posts over on the Denford forum. I wonder if Denford still have the file for programming the EEPROM, and if they'd be willing to make it public. I'm sure I've read somewhere they no longer have the ability to program them themselves, but I'm sure somebody with a suitable programmer could be found, although new chips may be a problem...

KMotionCNC requires a KFlop, which is Dynomotion's motion controller. I'd like to say retrofitting a Denford was straight forward, but it gets quite involved depending on what you want to achieve.
Once I get mine up and running, you'd be more than welcome to visit.

I can see ways of copying the EEPROMS with a USB device but its hard to tell if mine will be any good for that purpose. Denford wont release it as long as they can sell people USB upgrades as an alternative.

Will need to look into the KFlop vs Smooth Stepper posts. Is there a uk supplier of the KFlop?

I have converted a few denford machines (in the easy way) but the triac will be a different beastie with the atc. i will probably need to use an ethernet controller with all the inputs that will be required for the ATC, my normal breakout boards dont have nearly enough. Have wanted to get one for a while but cant justify the spend at the moment.

Just get a CS Labs IP-S or A device and be done with it. That is what I did.

Lol, if i could aford that option id already be on it after reading your thread. I bought my triac after reading it! moving that thing off a luton was a nightmare!!

Ah cool. Wasnt sure if you had seen the thread. Good learnings from that.

My machine today is basically nothing like before. It has the same hardware and uses some of the power / switch gear but other than that, is very different (for the better). To replace it with a newer version will be £10K+.

10+k for the whole machine or just the controls ??

Sorry, I meant the cost if I was going to replace the machine with something similar in the market today. You would be looking at a Chinese Syil or similar. 8 ATC, Flood Coolant, Servos for X Y Z and spindle AC Servo etc with MPG (not wired in yet). To replace the machine would not be cheap I think.

Plus, you can see how rarely these come up and how quickly they are bought. I will sell this once my new machine is built but if I have space I may chose to keep it longer term, very capable little machines.

Glad to see you got it finished

Ye, I need to tidy some wiring but thanks to you and many others on this forum for the advice.

The ATC isn't that much of a problem. At the basic level, it's just 4 inputs and 3 outputs.
The far bigger problem are the home sensors, as for most controllers you need to change them to newer NPN/PNP type, but I'm sure if you know a bit electronics, you could make up an interface board to convert the NAMUR signal to something more usable.
Plus you need a controller capable of handling the 24V logic, unless you want to drop all the controls to 5V (I really wouldn't recommend that option!).
And just for good measure the carousel index sensor is 5V (I swapped mine to a 24V version).
