I have one of their giant 140 watt c02 lasers. It broke in under 30 hours of use- just quit working mid print and omtech ran us through a hellscape of unhelpful customer service- where they DIDNT retain claims so we had to start from SQUARE 1 every day. It still is sitting unused and unfixed because we spent ~$8k on it and cantbafford to randomly throw parts at it to see what broke- OMTECH left us hanging. Ive never been so disappointed and upset in a company. That was a huge deal for us.
FYI, the Omtech machines so not meet UL/CE requirements. The electrical cabinets are not finger safe, the back of the key switch and E-stop gave un-insulated AC connectors on screw terminals (which you can get to through the main top cover. The machine I have works, but it's not the safest thing.
I have the previous generation model - same size and wattage. The autofocus on mine uses a probe that seems to work perfectly so far. The new sensor version seems like it is more complicated. I also had issues sometimes with cutting through certain parts in plywood. I found that if I use better quality plywood my results are much better because I think some cheap plywood has more internal knots / voids. For the air assist, get rid of that aquarium pump model and use a larger compressor - it will work much better and your cuts will be so much cleaner. I am using a kit I purchased from Laser Artifex that is great. For the issue with clearance between the wall and back, I designed a super-slim 90-degree output and just 3D printed it - these are really easy to make in Shapr3d. Also, I have found that trying to filter the smoke through a HEPA and charcoal unit is unnecessary. When I switched the filter unit out with a direct to outdoor vent I found it worked a lot better - hardly any smell even when cutting acrylic and no need to replace the filters which get used up very quickly. The filters also drastically reduced airflow so you can get by with a smaller inline fan. All-in-all, I have found Omtech to be decent with customer service. I had a question about how to set the power dial and they responded quickly (it needs to be set all the way up to 100%). And they sent me a free rotary attachment after I purchased the laser. I have maybe 400-500 hours on the machine and have not had any issues. I only wish it had a camera but I'll get around to ordering a lightburn one soon.
Be careful handling the honeycomb, they love to get their corners out of true square over time, then that can jam up the z-level as you move the z-axis. As long as those corners remain true, you're all good to use it. Regularly clean the belts with a silicone lubricant, that will prolong their life. Be ready to replace the E-Stop and sometimes the primary key switch if it has one, the E-Stops on our machines usually develop a short after 1-3 years of consecutive use, but it's an easy and cheap replacement, basically a slow burn consumable. USB connectivity is fine as long as it doesn't get jiggled too much. I'd disable the material height sensor, and use some form of NPN-NO sensor mounted to the laser head. That way you can swap focal lenses for different focal lengths without as much hassle, just use a metal billet on top of the material to set the z-focus. If you want to swap lenses, basically shorter focal length is good for high detail engraving, longer focal length is good for deeper cutting and for working on surfaces that are far out of being uniformly flat (we do an annual lasering of pumpkins that a 4-inch focal length lens is great for). Those would be my basic recommendations after many years of laser cutter building, maintenance, etc... I'm sure you'll start hacking your machine at some point, can't wait to see when that happens!
@ModBotArmy Gantry based. I look over 10 lasers 5 blm lt8.2 4k lasers 3 blm lt free 3k lasers 1 trumpf 6k trufiber and we just got a 4th lt-free with a 4k watt rating and a rotating pallet system for our fixtures
@@ZeroAnkoku yeah co2 has a pretty large jump still from k40 to next size and power up. Sounds good. Could be neat to check out one of those smaller galvos.
I had the genius idea of painting them black first 😂. One of my family members has been a successful artist for decades and I remember as a kid him showing me that he would do that. I think I must have forgotten why over the last 20 years but yeah lesson learned. For lasered ply/wood I will go light first.
The previous models are a lot cheaper - AF2435 is $3700 and it has panel pass-through on all sides so you can use larger panels. This is the model I have, though I paid $5k 18 months ago 😕

Welcome to the "Big Boy Laser Club!". The Omtech Pronto 40 is an amazing machine!
That thing is an absolute beast!
Welcome to the big boy laser club 😁 I'd recommend looking at a BOFA fume extractor inline with your exhaust fan as well!
The sign came out sick dude 🤙🏼
Thank you 🙏. I was really pleased with the finished result.

Very nice! I work with 3k, 4k, and 6k watt fiber lasers all day everyday at my job 😁
Holy cow, lol I’ve never used over a 60 watt. That’s intense. Are they galvo or all gantry based??
@ModBotArmy gantry based and we have 5 axis fiber lasers as well check out blm lt-free line of lasers they are sick

Was excited until I saw the price tag; let me know if you end up reviewing something more affordable like the Xtool F1

NICE!
Great review but you completely missed the single most important part: Can it be mounted on a shark?
@5:05 You mean pneumatic cylinders. Hydraulic implies liquid operated which those clearly aren't.

Frinkin LAZERS 😂
Paint the parts white before painting them with light colors.
Some colors do not cover well and need a white background, especially yellow.
