Denford Triac VMC with ATC Conversion / Fix

Have a look at this video my friend adam did on moving a mill...

Yea I noticed your garage was far to clean and tidy, time for some rearranging and much needed workshop space ?

Thanks. Garage is a mess actually. I think the pics paint the wrong image ;p

OK, up early, cant sleep. Some of many questions:-

Current plan is to use the CS Labs IP-A controller. Gary from Zapp (and JazzCNC) seem happy that this should work based on the info shared. Let's assume it does but I may have a drive or motor faulty (I cant test them at present), what do I do then? These motors / controllers look to be too pricy to replace like for like. If I get something that uses Step / Direction, I need a different controller? Also, if I am looking at 4th axis for later, how do I plan to take that into account? I dont want to buy and IP-A and S model, the costs are too high and I dont know if you can use both together.

In terms of other considerations:-

Convert to single phase. The coolant motor can be wired for this, problem solved. It looks like someone has fit a newer 24V PSU as per the pic below. Will use this for 24V logic.



I need 110V, not for a lot though, if needed, can fit a transformer for that. There is also a 15Volt feed that comes from the 110V line to supply power for the Axis Drive Logic, I assume I need this for the retrofit?

The remaining 110V items are a mix of relays and solenoids, mainly for the pneumatics for the ATC. I am missing all the solenoids and the pneumatic ram for the left/right of the ATC. i2i (thanks very much for your time yesterday), may be able to provide the details / measurements for a replacement.

There is a board where the X Y and X axis connect, do these breakout anywhere that allows for wiring to the new controller?



There is then the terminal strip however this doesnt seem to cover all connections, mainly power (wire 31 / 32 etc)?



In terms of connections needed to make this work, missing anything below?

E Stop
X Y Z Axis input / feedback
X Y Z Limit Switches
Spindle input / feedback (forward and reverse)?
Spindle Enable?
Coolant stop / start
ATC controls, carousel up/down (relays), Drawbar solenoid, Door open / closed (is this used?)
Do I need air pressure / lube float / guard contact (not sure if thats the main door or something else)?
Feedrate / Spindle override?
X Y Z Overlimit (wired via estop)
Carousel switches (in, out, up, down, sensor)

Phew, anything else?

In terms of things to get:-

Controller
PSU for 110V potentially, this is currently having 400V as its input, so need to replace this with 220V input
Missing actuator for Carousel left / right
Missing Solenoids (all)
PC - have a number of older machines, will make something from the bits
Monitor, want to use the existing arm / base if possible, ideally touchscreen
Mach 4 (possible?) or Mach 3
Possible buttons for common things (Stop / Start etc)

Anything Ive missed?

Is there any easy way to test the X Y Z drives / motors considering I have no real way to power anything on the 110V rail and 15V Axis PSU?

Thanks in advance.

I assume this is what I need for the missing solenoids?

110V, 5 way? If not that specific item, something similar? It looks like the previous ones were DIN rail mounted from the pics showing what might have been there before ...

Chaz i2i offered help I strongly advise you to take him up on his offer. You can't beat someone with actual experience of the machine your converting.
While Gary and Me have plenty of experience we don't have any on what's inside that exact machine. i2i Does and will know exactly what you can keep and what can be disguarded.
He's say's it's an easy enough conversion so I suspect he knows how to connect to any existing Motion controller built into the machine so you may not have to buy one at all.!!

Do your self a favor and speak to him before doing anything.!! (If you haven't all ready.)

Edit: Regards Moving it. !hink like an egyption.!!!. . . . They moved stones the size of your house with levers and logs.!!!

I have, extensively. We had an hour long call yesterday.

His view was that the machine should be retrofitted and that the existing controller is a waste of time.

Where he does not have experience is in the area of the CS Labs IP-A / S systems. This is where you / Gary come into the picture :-)

Ill post some pics a bit later once I have drawn them of what I believe the connectivity might be between IP-A and the current wiring, but I am not sure on this and will ask for feedback / guidance.

Thanks

Does this look like I can feed with 220V instead of 3 Phase to get 110V?


I suspect so but ideal to get some confirmation - saves me needing to get a 220 / 110V transformer.

Ok understand. When I get time i'll take a look at your schematic and Drive manual to see if I can make sense of what you'll need.

My suggestion is to break the conversion down into small parts and not try to eat the whole elephant in one sitting. SO
First concentrate on getting it moving and whats required to do so. Then deal with sundries like ATC and spindle, coolant etc.

There's more work to the ATC than you probably realise because as well has pneumatics you'll need ATC M6 macro writing to suit the controller so it can control the pneumatics and position axis etc in sequence before it can be used correctly. There will be ATC M6 start macros floating around you can use but still 99% chance if you find one it will need modding to suit the IP-A or controller your using.

Coolant etc is easy stuff that is just switched ON/OFF using relays/contactors etc controlled thru outputs and can be added at any time.

Give me a ring if your unsure.!
