3:24 The reason that doesn't work is because the buck converter is designed to produce a DC output. There are feedback circuits inside the converter that try to stabilise the output at the set voltage regardless of changes to the input voltage. It's not just due to the capacitors.

Another excellent tutorial Michael. Not a conventional electrical drive solution but innovative. Not using a TTL or analogue control and modulating the 12V supply is actually much safer. The LASER I've got is LASER ON when control is open circuit which is not a safe situation at all. I'd also recommend mounting on the left side of the hot end shroud rather than in front. That goes hand-in-hand with some 3D printed X and Y Stop extension prods and reducing the bed size. The idea is to ensure that the LASER remains over the print bed as that's a safer place for it. I'll give the software you've identified a go. Pretty much all the software I've found either doesn't manage X/Y position on the bed very well, is not intuitive or just goes crazy at times. I've also found that a lot of LASER software doesn't work well with marlin (or ender 3) and it can hang, and hang in the on state. Not knowing where the LASER is going to be and the potential of it hanging is not good obviously. Lightburn was closest to bug free software I've found but even that had comms issues and X/Y placement issues. I'm using 2.5W and have found vapour and fumes in a well ventilated room was not as big an issue as I expected. Light wise, getting technical info on cheap safety glasses I found difficult and where you can get the info or Australian Standards the prices are silly. I found making an effort to match wavelength of interest, do a pass through test on the LASER you're using and never look directly at the reflects light was the best way to go. As you've already suggested, excluding others from the area is wise. Safety wise, positioning has been a much bigger concern that vapour or light. ABL is very useful as it avoids having to focus on the work piece. One good feature of Lightburn is it can step down the Z axis on vector burns which means it could possibly allow 0.5W LASER to do multi-pass cuts as well. Not seen any adverse effect but the hot end shroud doesn't appear to be a great magnetic shield/keeper so the LASER mounting magnets are probably effecting the hot end fans to some extent.

For anyone with requisite coding and electronic skills, the solution to the 24v/12v PWM dilemma would be to find all the fan speed commands in the G-code, halve all the values and re-compile the g-code. An RC network of suitable time period, paralleled with a 12v zener diode would provide the correct drive and stop anything bad happening to the laser.

Hi bud, look I'm gonna be honest. I'm not 100% sure on your pwm control circuit. These things are typically 5V TTL input for power control. I see you've used the negative on your fan (presumably because it's switched low side by a FET). But due to the switching nature of a buck regulator, it uses ground reference for the output voltage regulation with a resistor divider connected to a comparator from that out voltage pot. By removing the ground reference (with the low side switch for the fan) you basically allow the buck converter to free float and effectively run 24V straight through. You'll have 24V transients going into the fan header until the regulation catches up through the feedback circuit.... This is why you have a delay when the laser power is set to 0. Better ways for this circuit is a resistor divider set to 5V with a 5V zener to protect the input to the TTL rising above the set value. Alternatively, use the 24V fan circuit with a 1K resistor into an opto isolator and use the output to toggle the buck converter to a TTL own signal into the control unit for the laser. Either way... I don't feel confident in the pwm control wiring you have. It might work. But I'm not confident it won't have long term problems or wierd issues like your having for power control.

Buck converters are literally intended for supply line conversion. Not as a signal level converter.
@TeachingTech5 жыл бұрын
After wiring the buck converter in this way, I've had zero issues. The issues shown at the end were from before setting it up this way. I appreciate you taking the time to post such detailed feedback. The laser according to the tiny info on the product page is meant to be powered from 12v. It has some on board components above the diode that may be handling the ttl. The way I see it the buck converter should be supplying a steady 12.5 volts at the output terminal, the pwm is switched on the ground pin and independent to this. I don't have a scope to verify but with a multimeter it never exceeds 12.5v.
@RamjetX5 жыл бұрын
@@TeachingTech You're pwm'ing the supply volts to the laser? Doesn't that laser have a TTL pwm input like most others do? Edit.. nope it does not. In this scenario, pwming the supply is all you could do. That said, the buck regulator will still be throwing in 24V transients into the laser on loss of ground reference. It's pretty risky to the health of the laser driver module. If you have an oscilloscope, you'd be able to see the buck converter lose regulation and produce these spikes. Using an external supply rail and a typical heated bed external FET is a more reliable and preferred design for this application. Come to think of it (whilst I'm having Macca's late lunch), caution should also be taken with the low side switch for the fan also. It's expecting a low power rating. Larger laser probably shouldn't use this circuit directly as you've wired also. That current is being handled by the transistor on your mainboard 3d printer PCB. If that pops. You have no fan either. Not taking a dig at you, love your content and big fan of your work.

Michael, as cool as this is, I think there are many serious safety things that you have not mentioned. Certain materials will produce not just smoke, but TOXIC gases if they are etched or cut with a laser. PVC is one of those.... and you're engraving right above a PVC 3D printer bed!! The $2 safety goggles that come with these cheap kits are also often NOT sufficient, and sometimes they don't even match the wavelength of the diode... encouraging the attitude of "how cheap can we do it" really is inappropriate for something with as many safety hazards as this.

Great project inspiration! I went ahead, crossed my fingers, and purchased the cheaper, higher-powered laser with the TTL-level input. As suggested in some of the electronics channels on KZfaq, I used a resistor network across the 24V fan, thinking it would drop voltage safely and instantly down to TTL levels. And it did. What's more, there is no delay turning on the laser, because there is no buck converter. And I did not have to unplug the fan. In fact, the fan speeds up cutting of cardboard. I have to use many passes at high speed to avoid flame out. Please never leave unattended.

I would use the DC-DC converter to get 12V from 24V, then a resistor voltage divider from the fan PWM to control a MOSFET that is powered from the output of the DC-DC converter (12V). The output of the MOSFET circuit will feed the laser PWM. The goal is to preserve the sharp rising and falling edges of the PWM square wave that directly impacts the sharpness and accuracy of the laser power and the engraved image.

I know your comment is a year old, but did you ever find a solution? I'm using the exact same setup, ender 3 conversion and lightburn. Wanted to used a rotary axis as well.

so as i understand, you removed modulation with stabilizer... i was trying to understand - i got ender 3 pro and 500mw laser 12-24v... also i got skr mini v2, so by default there no pulse modulation visible..... also in marlin configuration firmware files - you can define fan will be with pwm or not, i think - its 2288 line FAN_SOFT_PWM

First off very good and informative video for an upgrade I can see myself trying in the future, big thumbs up, but can the same wiring technique be used to power a pwm fan? the reason i ask is because i have an ender 3 v2 and want to use noctua a4x20 5v pwm fans for the hot end and part cooling and your is the only video that seems to show a way round this, sorry if this is going off topic but any help would be appreciated

Can this kit engrave glass? We need to put Names on drinking glasses as a present. Don’t want to do it by hand…

please if someone can help i cannot find a solution. same laser wired the same way to my ender 3. the only difference is the buck converter that came with mine is not adjustable. if i set my fan speed (laser output) to anything below 50% i get -12v.. so 0% is -12v, 25% is -6V, and 50% is 0v.

Wow, 3 hours for only one layer is crazy. I won’t be laser engraving anytime soon.

great tutorial, thank you! just one question. is this compatible with the Creality 4.2.7 board with out having to install the buck converter? thanks for the reply

Will that work with a 8 bit 3d printer mainboard? For example... will that work with a Sunlu S8?

Does your laser have separate power for the cooling fan mounted on the actual laser module? If so, what did you connect this to?

Do I have to remove the spade connectors to the power supply if I want to switch back to normal printing? Or can I just remove the connector to from the cooling fan port and plug my cooling fan back in?

In some videos they connect directly to the 24V supply, Can we do it with this laser? or we must use regulator? Also Can we seperate the fan cable to 2 pieces?

You can get laser modules in 12V and 24V versions. You only need the buck converter if you're using a 24V printer (like the Ender 3) with a 12V laser module.

Hi, In this video you covered the 2 pin laser and mine is 3 pin 2.5 W laser and I am not sure about the wires, there is ground, pwm and 12v, I have a Cr10s so 12v I'll plug into hot end fan positive, then should I solder ground to the part cooling fan buck converter out negative or should I take it from the hot end fan too ? and pwm pin should propably be the lovered voltage from the converter right ?
