If they are not moving, just holding zero position,  a classical Galvo amp (~5 mm mirror size) draws about 160 mA positive rail and about 120 mA negative railm and needs 12 to 24 volt rails for maximum performance. .When they move, if tuned for full scale marking or laser show speeds, they can have 6 to 8 amp peaks during acceleration and deceleration. A good galvo amp puts minimal energy into holding position, probably  600-800 mA DC  for full scale deflection to one side.  You'll have two of those.  The 40 mA difference between rails at idle is the position sensor LED drive.  You will have an X and Y axis on this system so there are two sets of idle currents.

I doubt  they are using Class D, its often very difficult to close a DC feedback loop as needed with the galvo, around a commercial IC based  Class D amp.

For those who do not know, low inertia galvanometer scanners are one of the fastest precision controlled objects on a the planet when they have either a capacitive or optical position sensor and a good PID loop with notch filters.  Bandwidth can approach 7.5  KHz for very small angles on the latest systems.
But for this application they don't need to be anywhere near as fast as laser-show galvos.

they came to their senses and realized their product was illegal as designed. so they announced it will now be downgraded to IIIB and have an enclosure.

watch their backers lose their minds LMAO!

This update posted after the one you mentioned is even more hilarious :)
Take a look at the letters from Kickstarter linked in that post. They have until Wednesday to persuade their backers to switch from the tiers for a "free-air-cubiio" to the shield one. All perks from backers that did not switch will be canceled and refunded by KS.

Someone linked to https://www.tomtop.com/others-216/p-e2565b-eu.html in the comments.

What extra shielding would be required to make this safe(r) as there is only 1 piece of "shield" on it  :palm:

So funny how they all don't get that they're wielding a freaking dangerous weapon when using this thing. Whining about how they can no longer put it on a skateboard, then say that the $99 illegal Chinese import can do just that... yeah well, try holding that Chinese company liable when you blind yourself (or someone else!) with it :palm:

"Kickstarter is forcing us to do these changes."

no, the fucking FEDERAL GOVERNMENT is forcing you to.

if you sell the original class IV laser with no enclosure in the US, you will GO TO PRISON.

jesus, these people are seriously retarded.

The following is an example of a someone who should not be allowed around any tools or machinery lest they recieve a Darwin award. :palm:

Please consider having the laser operational when the metal plate on the shield is removed, so that it can still work on bigger flat surfaces. Full spectrum laser in the US have a machine that does this, so that you can engrave on large items, so as something on a larger scale is already being sold around the wold, their surely should be no safely issues!!!!

The company is Taiwanese. They literally have no clue that there are actually (*gasp*) regulations in place for laser
products, since down there pretty much anything goes.

Cubiio company is in Taiwan ... So not a whole lot of difference there.

The thing that hits me hardest about this is that Kickstarter is stopping people from getting what they want. However, they don't lift a finger when people get defrauded by other groups. Kickstarter has a wonderfully screwed morality and set of ethics.

He doesn't realise the simple fact that Kickstarter is forcing this rule on Cubiio because the product in its original form would not be permitted to be sold (even imported) in most countries, and thus the creator could not deliver rewards (not that they could be able to deliver what they're promising either)

Well, I am not sure that even the Cubiio team actually realizes this. The KS letter talks about "fulfillment risk" (aka not being able to deliver) but that it is because the product has no chance to pass any certification and be legally sold in the US or Europe is not mentioned anywhere. The Chinese stores like AliExpress or Banggood are full of dangerous contraptions like this, so they could be feeling unfairly singled out:

So while that backer may be clueless, I wouldn't blame him for not understanding this. It is not him (or her) who should know that!

Some of those dodgy-looking home engravers look like they might be halfway-decent for making circuit boards on. I've been using a milling machine, but it's so finicky only about one in three boards comes out right. I usually use stripboard unless I really must have SMD parts.

They usually sell these cheap (and crappy) CNC machines as "engravers", because a bluray diode in a casing costs peanuts and hey, extra feature!

Yes they do.  They're just in denial, due to a million plus dollars being on the line.

So while that backer may be clueless, I wouldn't blame him for not understanding this. It is not him (or her) who should know that!
Yeah, fair enough - but if you back a Kickstarter you're responsible for doing some research and critical thinking.
Even Cubiio linked to the AvE video (that rips it a new one) in one of their updates.

Maybe this whole KS is just a scam to get AvE more viewers!  Dave should think about this  :-DD

Here's a video review of another cheap laser engraver from Bangood:



The safety problem with that thing is downright spectacular, as is demonstrated.

Yeah, no crap given about safety. Just bolt a laser diode to a gantry and call it an engraver ...

I wonder if most bakers will get it, if it ships. Customs may take it out and destroy it.
I've heard of that kind of thing happening before:

(first 2 mins)
Could be fake, but still more realistic than a laser cube.

I cannot help noticing that all these bullshit projects have repulsive "i-Apple-Smart-Fad-Connect-Online" style aesthetics and nomenclature. We are now in the Stoner Age.

Did they really just make an IGG? https://www.indiegogo.com/projects/cubiio-the-most-compact-laser-engraver#/

After all, they think people are stupid and would not notice.

Someone posted it on the Kickstarter comments and asked if it was theirs.  They said no, and they would ask IGG to shut it down.  Looks like they did.

It'll be the usual case of a scammer cloning a successful campaign on another site, hoping to get some easy cash.

Looks like they have added a three axis accelerometer to. "Enhance" safety.
