Denford cyclone conversion

[m_c]

Analogue controllers rely on the servo encoder to know how far things have moved (I'm assuming you'll have encoders fitted given your machines age, but there is a possibility of having resolvers fitted, which are a nightmare to use with any modern controller).
The controller is continually adjusting the analogue output to maintain position based on the encoder position.

Provided your servos have encoders fitted (there should be another multicore cable on the rear of the servo), a KFlop and Kanalog will work.
The KMotionCNC software is pretty basic, but it does the job.
The biggest issue you might have with a KFlop, is most of the config and any custom coding is done using C programs. It does mean you need to understand at least the basics of C, but it also means it can be programmed to do some quite advanced controlling.

I did have a quick search of the Denford forums last night after posting, and see Duplomatic turrets appear to have been used on newer machines. I think the biggest issue you'll have with the turret, is figuring out how to control it. I couldn't see anything.
I've just done another search, and found this document on the linux cnc forum - https://forum.linuxcnc.org/media/kun...50-1412-en.pdf which seems to suggest Duplomatic supply their own control board, so I'm going to guess they don't publish exactly how the turret operates. And if you don't have that controller, you could have a major problem.
I'd start by asking on the Denford forums, and emailing Duplomatic (https://www.duplomaticautomation.com/), to try and find out about the turret, as without a functioning turret, a Cyclone isn't much use.

Decided to go with close loop steppers 4nm ones from stepper online they arrived the day before I came on holiday so only rigged them up on the bench but they appear to be fast and powerful

I got the spindle running on a 4kw inverter and it seems fine
The turret is starting to be a concern as I don’t have the controller card for it and duplomatic have not responded to emails
Do you think it is something that could be done with an arduino? From what I have read the outputs from the four sensors are 24v so some form of voltage shifter would be needed to get to 0 to 5 volts as needed by the arduino

There is a ucn controller card on eBay in America but it is over £300 shipped to the uk then likely plus bay and import tax so not particularly the way I would want to go

I did some custom code for a Duplomatic on Arduino - heres a vid of it on a 'bench' - the connectors simulate what the duplomatic would be doing.



Personally, if you didnt have the closed loop steppers, Id be doing servos. I dont think Ill ever do another retrofit without servos in future.
