Gallery / Warco Super Major Vario 5Volt Supply Upgrade
« Last post by Joules on Today at 06:01:13 PM »
My mill has just turned a year old and finally out of warranty.   One thing that has annoyed me from the start is the awful 5v supply they fit for the digital tacho.  In effect they cascade 24V, 12V, 5V linear regulators it's an awful arrangement all mounted in a plastic box.  They run hot (note:- they are not bolted down so they don't all fry at once) and on occasions glitch and freeze the tacho.  On my todo list was swap out this crap for a far more efficient step down switching regulator, these things are cheap, very efficient and so run cool, but they expect DC in not 24VAC.  When you rectifiy 24VAC though a bridge rectifier you get 33VDC out, so pretty close to the upper limit of 35V for the regulator.

I use a lot of these in various projects and the beauty is, you can set them up on the bench prior to install.

Now rather than just rip out and throw away the whole boxed PCB, I decided to make use of the old board.   First off pull all the regulators, some track cutting and then parallel up the capacitors, not pretty but it will all live inside a steel case.  The regulator is held on the PCB with 3M double sided tape.  I am not expecting heat issues as the 3A regulator is supplying less than 200ma.  Once the PCB was modded, time to mount it back in the case.  it wouldn't be a Joule's project without some 3D printing, so the mounting plate for the board is 3D printed, the PCB is screwed onto it and the mounting plate.  The mounting plate is stuck with 3M double sided tape inside the control cabinet.   Better to have some air flow as I do plan to run the 5v supply to other areas of the mill for future mods.  Install complete the mill was run up and tested for any glitching, nothing it just works, those caps are doing a good job smoothing the 24VDC coming off the bridge rectifier.

Despite my dislike of the old PCB it has actually turned out OK and made a neat install that saved me the time of designing and making my own PCB and keeping my scrap parts to a minimum.

I think this is cross drilling jig Grand Tourismo :lol:

One feature I haven't seen before is locating with a key slot. This has keys to index object into V. Can't figure when I would need that feaure.

Number 2 is a cross drilling jig. It is a mid-range item. The smaller version is a mildly-piqued drilling jig. Its big brother is an angry drilling jig.

Hello everyone, how can a new language file be implemented?
Regards
Implementing a new language is rather tricky. There cannot be any special, non-English characters in the translation.
Also the individual strings have to be rather brief. Apart from that, some binary patching is more or less required to get it done.
What language would you like to translate the controller firmware to?
Feel free to PM me to discuss options.

Cheers,
Benedikt

Tools / Mystery MT2 test bar and mystery V-block kit
« Last post by PekkaNF on March 17, 2019, 10:13:20 AM »
One local measurement manufacturer went liqudation and all tools and products were auctioned off.

Few mystery item trickeld me down.

1: There is a relly nice MT2 test bar, but I don't recognize the use of the another one. It has cylindrical part that has two narow grooves lengthvise 90 degrees appart. It looks like a setup tool or measurement tool.

2: There is a relly nice V-block set. it has hold down clamps and various keys to index the prism - or part in the prism.

 The mystery feature is a hole in the middle of the V-block. There are matching bushing and pinst to it. I guess the V-block locates round object to measure/hold and axially there is hole location or such feature with these lapped preicision parts.....that simple or something way more sofisticated?

Appreciate feedback

I have managed to find the original article I read on how to do this on facebook. It includes a schematic of the VSO output and the location of the capacitor to be removed.

Glad you got it done as it seemed rather a marathon, but I seem to recall you had other projects, interruptions and life in general to contend with along the way.
Looks Good, Sounds Good so congrats.
