    Did you get your water flow sensor working? Which one did you buy? I have been looking for one but not sure which one is compatible. Thanks.

    I went to the diagnostics screen on my controller, and there was already an input showing for a flow switch. A little detective work located the switch hidden behind the water / air connections panel. it was wired up by twisting the connections together and covering them with electrical tape. I did a proper solder and heat shrink job to fix it. I have tried pulsing the laser without the water on and it wont do it, and gives a warning "no water flow" on the screen.

    I have had a Redsail X700 since July of 2014 and had great results. However I did buy it directly from Redsail in China. One thing that I do know is that if your laser does not have the Laser Tube Extension on the right side of the unit, it cannot have a 60 watt tube in it. The 60 watt tube is about 1150cm long and will not fit in the laser case without the extension. By looking at the picture of your X700, I can see that there is a plate covering the opening that the tube would have to stick out of on the right side, so you would either have a 40 watt or 50 watt tube. In addition, the Y Stepper motor is mounted in the 50 Watt version of the machine in such a way that it would block the attempt to put a 60 watt or larger tube in place.

    The X700 does not come as a 110v unit. Redsail only offers it as a 220v unit. The control board will run off 110v as it's low voltage power supply (which controls the stepper motors) has a voltage regulator that works from 100v to 240v, but the laser's high voltage power supply will only work correctly off of 220v single phase. If you plug the unit into 110v, the system will operate, but laser output will be dramatically lowered (you should see a plasma from one end of the laser tube to the other, if you don't then check your input voltage to the laser HVPS.

    A few things about 220v, most of Asia uses 220v single phase as does much of Europe. In the United States our 220v is two phase. So it is necessary to use a single phase 110v to 220v converter to properly run the laser. The blower that I received was the very large commercial blower and that draws the most amperage of the total system (laser, exhaust blower, chiller, air pump) and if you run it at 110v it will run slowly while doubling the amperage drawn, melting switches, plugs, just about anything. I ordered and use a 5000 watt converter to power the blower and the chiller. I have a second 3000 Watt converter that I use to run the laser itself. I have a third 3000 watt converter that I keep for backup, as not all 110v to 220v converters are created equally, and it is really a bummer if one burns out during a high use period.

    When it comes to converters, the more time the laser is continuously in operation, the bigger the converter, in terms of watts should be. In addition, most of the 110v to 220v converters that I have seen, have both 110v outlets and 220v outlets on their from panel. It is easy to mistakenly plug a 220v device into these units 110v outlets. This will lead to low laser output, and melted parts in both the laser and the converter. Remember that there is a fuse in the input power receptacle of the laser (which is hard to find, but it is there). Finally, many converters have input voltage selection on their back panel; make sure it is on 110v input and not 220v. The power plug that you will receive with your X700 looks like an US 110v plug, trust me, in the rest of the world, they use that plug for 220v too. I do not have any experience with the new exhaust blower that mounts on the side of the X700.

    A few thoughts on the laser tube. It is impossible to soldier to the points on the tube as the connection points seem to be a nickle based wire. in order to soldier to these points, they would have needed to be copper plated first ( a trick that is used on the leads for space rated transformers using nickle wire). What Redsail really means for you to do is to wrap the wire of both the laser HV and Ground leads arounds the connection points/posts, soldiering them in to sort of a ring (they will not soldier to the posts, but they will make a tight connection), then use black electrical tape as an insulator. If you have High Voltage arching, you will be able to hear it during test, and you should check your connections and tape ( I have never had leakage using vinyl electrical tape myself).

    A few thoughts on the air pump. First, throw it away. Then go buy a compressor from California Air Tools (pricey, but very quiet). You need a good volume of air not only to keep the lens free of debris, but also to exit the nozzle of the laser head to help with engraving and cutting. This is particularly important with cutting. With the air pump, you might not be able to cut through plywood. With a compressor providing 20 to 30 lbs of air pressure, you will cut it in one pass, assuming that you have correctly aimed the laser.

    A few thoughts on upgrades. I have upgraded my X700 to a RECI 100W tube and power supply and have been very happy with the results. I am able to cut 1/4 inch plywood in a single pass with this setup. I did not convert my machine to 110v at the time, but if you replace the cooling fans with 110v models and put in a RECI 110v HVPS, it would then have be converted from 220v to 110v. I have included a pic showing me installing the RECI tube in my X700.A warning about the redsail x700 60w machines on ebay right now.-1-recitubeinstalled-jpg

    I want to add water flow protection and that setting is behind a protected screen.
    Luckily there was a quick youtube video on changing from Chinese to English

    BTW its not RD8888
    What is the Youtube vid for changing Chinese to English?
    Thanks,

    For you guys that bought these machines on ebay shipped from California, is it correct to assume that they have already cleared customs etc and that there are no surprise importing costs? I don't care that the output of the laser tube is lower than advertised, the cut area is so much larger than the next cheaper machine it is very tempting.

    Are all these red 500x700 60w machines Redsail or are there copies as the one I am looking at looks identical but no mention of redsail
    comes with the big grey blower fan

    As far as I have been able to determine, there is no US distributor of Redsail Products. On eBay, Redsail uses CNCCheap as their direct sales arm. All Redsail Lasers have a big Redsail Symbol on the front of the Laser. Check what the ebay "Brand" says, if it is not listed as Redsail, it is not Redsail. I have purchased 2 X700's via CNCCheap in the last year and have been very happy with them. The current Redsail does not come with the big gray blower, rather is has a low volume blower attached to the exit vent on the machine. I supplemented this with a 6 inch vent blower on my latest machine and have been very happy with the noise (db level) of this new setup as opposed to my first X700 that came with the gray blower. The gray blower is very loud and pulls more watts than the laser itself. Hope this helps.

    Thanks very much for your instructions here and good feedback to our machines, yes, CNCCheap is the only one exclusive Redsail Laser distributor on ebay, no any offices in US now and US ebay resellers, they are selling imitation with Redsail Brand, they produce same color and structure, but not Redsail machines. Attention, please, all customers.

    All Redsail lasers are selling on ebay by the exclusive distributor CNCcheap just will be shipped from China, no any machines in California.

    Is the machine shipped to my door or would I have to pick it up at a seaport? What is closest to Cleveland Ohio?

    n0kjf, I'm not affiliated with Redsail so will need to confirm with them if you're planning to buy. The shipping you pay to Redsail is shipping to your nearest port. If you want it delivered to your door it will be through a 3rd party and *I think* you need to arrange it yourself. It's possible that the customs broker could help you with that too. I ordered one a few weeks ago through CNCCheap but I'm picking it up. We did discuss shipping it to me, but LA is not far so I'll just be picking it up.
