Over the last few weeks off and on I have been working on an idea for an info-graphic. https://a360.co/2XZg1u0[ NO LONGER VALID] (as of now it is complete with maybe a tweak or two to go). The viewer linked just above allows manipulation of the model in zoom and orientation and if you click on a wire it will highlight it so you can look at where it runs to and from.

Some of the wiring diagrams out there for CO2 Laser systems are average at best and some online information from sellers is just plain misleading or even wrong. So I started the project above to try and put some of those things into the past. The file on the 3D viewer is free to use by anyone for personal use and I expect anyone using it as part of their commercial businesses to give proper attribution otherwise enjoy it :) If anyone wants a particular model from it I will consider that on a case by case basis.

It is based in Fusion 360 and represents over a dozen custom models either created from scratch or heavily adapted from existing ones, two of them started out life from https://www.furtherfabrication.com/ in their basic form and were then remeasured and changed. Those models are then linked and added to the overall model which is where joining all the bits together and placing them goes on. As part of that Fusion allows bringing in manufacturers parts when available so things like relays, filters and some pneumatic parts are those. There are a few compromises made for keeping it cleaner looking such as omitting separate power supplies and the negative limit switches. Happy to answer or talk about specifics in more detail if anyone is interested but maybe here? https://rdworkslab.com/viewtopic.php?f=111&t=3901

Currently is consists of 17 specific Custom Linked Models, 150-200 individual sketches and over 1000 bodies. What this means is it needs a good chunk of processing power to build and create it but the online viewer can be used with my lowly Intel Atom Mini PC.

The model also allows for stripped out or individual sections to be rendered out to make them clear for discussing the various parts involved in a Laser System. The plan at this stage is to do this with explanations of each part and allow discussion or questions about it. This Emergency Stop Render will likely be the first such topic here with Renders like this.

This can be done with the online model by RIGHT Clicking on the part which gives you a series of options including HIDE this part. Makes it easier to drill into the model as a reference or even just to highlight a part or concept to others using the Markup Feature. The Easiest way to take a Screen Capture on Windows systems at least is to use the "Print Screen" button on your keyboard then paste it into your favorite image processing software to edit it or save it (https://www.irfanview.com/ is great for this).

and with the bits removed for easy viewing of the relay bank

and for good measure a Random markup of the Air Assist Solenoid from the other side of the model.

Wow... just wow. I just spent 15-20 minutes of the life I have left marveling over the share. I say again that this is a great contribution to the forum and to humankind as a whole. Thanks Gene

This is the way lasers should be... the ones I have touched are much simpler of course.

It has been an Epic but along the way I have broken part of Fusion and found a bug for them to fix so I guess that is a win for others. Learned a heap of new tricks to add to the bag for future Projects and also I think I finally am getting to terms with managing the timeline and an order of operations in Fusion so you can make a change to an earlier item and not have it break something else later.

As to the model and a few of the choices/compromises I made.

The 6445G Controller seems like the most likely candidate we will see from now on and into the next few years on 'most' new machines. Basing it on the older 6442 didn't seem sensible and picking one of the others such as Trocen etc would just be dumb IMO as they represent a much smaller number in the market.

Basing it on a nominal 100W style of wiring layout means it needed a Cooler and it made sense to block one in to show the alarm but it also made sense to block in an optional flow switch for those with either a bucket or a different cooler without the alarms.

The Stepper drivers I have shown are not a recommendation but are one that will do the job and are widely available. When I get to the stepper section I can expand on some of the others and the labeling they use as there is no real standard. The Motors are a blob and are not that important other than to show.

Initially I was going to just show one power supply for simplicity but went with the more typical two. One for the Controller and accessories and a dedicated one for the Steppers (could be 24 or 36V) I will expand on why in a separate thread.

Why a Z100 Power supply? I have spent a lot of time deconstructing Chinglish meets Swahili :roll: to try and get to the bottom of what is meant and this is one of the more modern offerings and it actually feeds data back to the 6445G controller to display both Current and Output Voltage on the display. It will be nice not to have to feed any conductor hooked up to the HV side of the Laser power supply anywhere near the control panel and the user and also losing the clunky analogue mA meter.

The Bank of Relays instead of switching from the Auxiliary control panel? For similar reasons of safety only having low currents and in most cases LV DC switched here is much safer (if you spill a Coffee on it :shock: ) and is just standard industry practice. It also becomes an issue in the 110V parts of the world as you are switching much larger currents than the rest of us so the switches need to be larger to cope.

That's all for now at least Coffee first then some Gardening in the Sunshine to replenish the Vitamin D after to many hours staring at a screen.

Just for general knowledge... the 6442 controllers will also read out the current, etc if you have a compatible power supply- they also have the CN0 connector. The Bodors I worked on had Reci power supply and the current could be displayed. I still think that clunky old mA meters are easier to keep an eye on personally.

I'm simply blown away by your illustration. :o I have been looking at the world from an 8x11 sheet of paper and falling behind the dimensional realistic view of 3-4 dimensional drawing. You are my Einstien :D :D :D for the week...
