Sovol 40W Engraving Laser Module (5W Output Optical Power), CNC Laser Head Kit with Eye Protection Design, for SV Series & Ender Series 3D Printers and CNC Engraving Cutting Machine

Here are some of the parameters I came across when utilizing this laser with my Ender 5, but if you remedy the issues below, or work around them, then this laser is a great budget value so far.Laser creates a Dotted Line: - Be sure to run the power at 255 (ie 100%). Anything lower and the fan control will Pulse the laser creating a dotted line instead of a smooth line. - The laser Power port should be connected to the K1 fan port on your Ender, instructions are correct in this regard.Scorch issues: - This laser is quite powerful, so much in fact that it will likely scorch wood during engraving if you run your laser speed below 1000mm/s - I found I have to move the laser at 2200mm/s or faster to prevent sooting at 100% - You can use a PWM signal generator to lower the output, see belowHow to modulate laser power: - If you wish to modulate the Power of this laser, I recommend purchasing a PWM signal Generator with adjustable frequency and duty cycle (I used a DROK PWM Pulse Frequency Duty Cycle Signal Generator) - You'll want to buy a JST 2.54mm 2 wire plug to connect the PWM signal to the laser PWM port. - The Signal frequency should be around 10-20 kHZ for a smooth cut, lower frequencies will start to create a Dotted line. - The Main power on the laser should still be connected to the K1 fan port on your Ender.Mounting - Ender 5 with BLTouch: - Mounting on the Ender 5 is difficult if you have a BLTouch installed, as the laser can hit the front support bar if your cut exceeds 200mm on the Y axis. There is a very small tolerance if you print a bracket for the laser and mount it just above the bar clearance and remove the magnetic red shroud.

Make sure your printer is 24v and the power output at full fan speed is 24v, connect the long cable to the laser power port (not the TTL) and the other end to your controllable fan port making sure that positive and negative going from your printer to the laser are wired correctly first. If you are plugging it into your motherboard's controllable fan then that's all you need to do. As for other printers, I can't say but for mine that's how it works. Just be careful and ensure the correct polarity. I'm not responsible for any damages on your end just wanted to share how I got mine working.

Installed this on my 3d printer. I need firmware and software to even test it. The information provided on the sheet of paper directions is wrong. The links on their website don't work. Tried to contact the company through Amazon and they never answered. Tried on their website and they never answered. So if you'd like to follow with your 3d printer and then never know if it works and then have to go back and take your 3d apart again to uninstall it, then this is the product for you. Can't give you a review on how good it is since without firmware, who knows.Stay away from this product and company.

So as everyone said the laser has 0 instructions on wiring. However I did a bunch of messing around and I believe I have the answer.TLDR: 24v Power needs separate line/power adapter. PWM needs to be 3.3v max. Use voltage divider to step down proportionally what your printer fan voltage is.The laser is 24v which is the power in. If you plug 24v in without anything into the PWM you will have full power laser. Most people plug the laser (Power) into the 24v Fan of their printer but that will not fire on the cooling fan for the laser 100%, it will pulse the fan in relation to the laser power. So you need to have a separate 24v power and a separate PWM wire.Here's the part no one else has figured out. The PWM is max 3.3v I tested it on my power supply and at 3.3v, for the PWM the power reached 100% (~40w output). So you need to convert your printer fan voltage which varies and controls the power, from 0-24v to 0-3.3v. (I have a 12v printer and with the same solution I am running this laser pretty well)What I ended up doing is using a voltage divider with a few resistors (look it up online) which stepped down proportionally the voltage from the board to the laser. If there is a better method I would like to know, the voltage divider is sort of janky.

As soon as i opened the box and held the laser I knew it was what i was looking for ...To make sure I wired it all up using the videos they provide on YouTube for my Ender 3 printer. That was simple enough for me but if you doing the same make sure you know if you do or dont need the jumper wire and install accordingly. anyway...I hooked it up, plugged it all in and put on the glasses then turned it on... I was holding one of the boards and tried the power out put at 25% for a few seconds and then 100% for a few more seconds... in any case you can see the results in the images I provided.I am not including anything done with computer having motor control as this was just a laser but I am glad i bought it and find I am becoming a fan of sovol pretty quick as I enter the 3d printing and small laser cnc world...

The media could not be loaded.  So far been really good.. Had received a faultily unit at first but company quickly replaced and got me up and running with a new 1.. Works well at 50% power and has not giving any problems. Only removed the laser shield because it cause to much smoke to be trapped around laser beam..

Funciona y cumple con lo descrito.

Update from my past review if it's not simply replaced with this. From what I can tell so far this laser is more than what I thought I was getting. The power is there as it cut through the practice boards provided and I was successfully able to engrave a hockey puck at 25%. For the Ender 3 v2 you connect the laser to Fan 1 on your mainboard. You have to disconnect it every time to reconnect the fan, I did not use the splitter as I was concerned that I would forget to disconnect the laser when 3d printing (personal preference and maybe I will get more confident with time). You attach the laser to the Ender 3v2 with a clip you 3D print off of Thingiverse. I use Lightburn software, and selected Marlin in the setup and there was a LOT of messing around to get the right settings. This is expected as you have a 3d printer from one company, a laser from another and software from yet another. That's a lot of variables. After much research I discovered that Marlin is not the best firmware for lasers but it's what we have with an Ender 3v2. In Lightburn you need to mess with the speed and laser intensity as well as white movement (when not burning). You MUST also use Absolute Coordinates or else you risk burn failure. It took a while to figure out that one and I almost gave up due to multiple failures. I was initially only able to burn very slowly but with trial and error I was able to get it sped up with decent burns. If you are getting this for an ender 3v2 you are a hobbiest and should be used to expectations of fails and required tinkering. I doubt it will work well right out of the box but these comments should get you in the right direction. The problems I experienced were not the fault of the laser, but with the fact I was moding an Ender 3v2 and it required software tweaking. Do not expect much specific documentation online for this laser on the Ender 3v2 but information about other setups can provide clues on how to proceed. Overall I'm very impressed.

Funciona muy bien.

gut durchdacht

Did not fit my laserI could not hook up to my system without having the wires sticking out of the controller box from the side which would give me a chance for an electrical shock.

Solo funcionó el ventilador, la use en dos equipos ender 3 pero no hizo nada, tuve que regresar el producto y compre otra diferente.
