I will sell you my redsail 3040A for $900 all it needs is a $200 board.

Update...

To begin with, I was told to "Earth" the unit by Redsail so I got to looking... ...should explain what I seen...


I did "earth" the unit and to my surprise, the main power converter is NOT grounded to earth from the 110. This may be ok over the pond but a BIG :nono: here in the US. Needless to say, I brought that up to standard.

Then I went on to "earth" the machine...
Earth means simply the SHORTEST route to GROUND. This I did and the Y motor stop sensors stopped working, this tells me that there is an improperly filtered or open ground in that circuit probably in the PCB design it's self so I disconnected the earth knowing that it will NOT solve my before mentioned problem with printing. I then began looking very closely at the circuitry and stepper driver circuits, all there is ok. There was a jumper connector to jump several circuits from one board to another and this plug on the secondary side was HALFWAY PLUGGED IN. This is only SLOPPY manufacturing in my opinion, Sorry Leo but SOMEONE NEEDS TO SPEAK TO THE PERSONNEL IN MANUFACTURING ABOUT A QUALITY ASSEMBLY JOB. I feel that since I paid a lot of money for a product, it SHOULD BE ASSEMBLED IN A QUALITY ENVIRONMENT. If most of the machines have the same version PCBs that mine do, earthing WILL cause erractic problems in the 5volt circuitry. Be aware...


This should be taken to heart in China, you could have an EXCELLENT machine worth MUCH MORE than what I paid for it only IF:

#1 and FOREMOST- Control your quality and inspections CAREFULLY.
#2 Do away with the TROUBLESOME "keydog" that is needed to operate the software / use a product key instead.
...and #3 Upgrade the software to be more END USER FRIENDLY, NOT programmer friendly.


:edit: I forgot to mention, my machine is lasing BETTER now in the engraving mode than regular cutting...

To ivirscar
Glad hearing that the machine runs fine and sorry for what happened. We will try to find the reason, it is very important for us. Please check the email, thanks.

[Tashammer]

this is totally off topic but i have been getting such a buzz (again) about the way the all the folks in this thread and many others work together, argue together, sulk together, solve and assist others solve problems. What a gas!

Da Jia Xin Nian Hao! to both Leo's and all of us.

Hi. I wonder if someone can help me. I recently purchased a budget 40w machine. Much like the common machine you gys have been discussing. I set it up and pushed the test button but was hearing a wierd crackilng noise coming from where the circuit boards are kept. I discovered that one of the wires had come loose, which I soldered back on and this seemed to fix the problem.

I then pushed test and the machine began to whir like it was testing the laser. I wasn't too sure wether to look however incase the beam hit me in the eyes! After it stopped whirring I hit the test button again. But nothing happened, the ammeter doesn't even flicker! Does this sound like the tube could be gone? If I test the positive and negative end of the laser tube with a handheld ammeter will this verify that the power supply is ok and the tube is shot if I get a reading? Getting a bit worried as I haven't been in touch with the guy since?


Thanks in advance.

I was looking at the HX laser website and found their short movie is quite impressive even though their english is not as good as it should be.

The way they teach you how to set up their machine is acceptable but not very good. - anyway this is the best you can find on the web at the moment if i am not wrong.

Normally if you have a cracked tube it is not advisable to start up the laser.
The high voltage supply might get damaged when it is short circuited by the water.

The best you can do now is to order the tube and the laser power supply.
Replace the tube first and then test if you can start up the laser.
If you can't start up the laser, you now have to replace the laser power supply and then start up the laser again.

Hopefully you have a blown fuse on the laser power supply - please check the fuse on the PCB. And DO NOT forget to replace the tube first before you power up the laser again.

DO NOT forget about all the safety precautions that you have to take while repairing the your laser machine.

Lastly i hope your request for help in this forum is genuine and not to discredit others.

I think China companies have done a good job of discrediting themselves already.

I think China companies have done a good job of discrediting themselves already.

It is true, what you have said.

What i mean is that, there are some "members" which i think create stories about failure of their laser machine.

When you tried to help them, they are unable to prove that they have the particular machine and hence it is frustrating to type on a keyboard for 10 mins to answer in a good faith. - i might as well go surfing the web or watch "my tube"

DON'T. The voltage involved here is far in excess of the capibilities of most voltmeteres. You should not even think about trying to measure this unless you have the specialist high voltage equipment required. The voltage in in the order of 20000 volts with a decent amount of current. This means an arc will jump in excess of 2 cm and will kill you. Testing the power supply needs a high voltage probe that looks like this. Do not attempt to test the high voltage supply unless you know exactly what you are doing.

Hi,

Please rest assured that my questions are legitimate and that I am not out to discredit anyone. I just wanted to get info from you guys just incase I got no response from the company that I bought my machine from. I read these forums before purchasing my machine and was led to believe that some companies can lose interest after making a sale. I have however been in touch with this company and they are doing what they can to help me which is great

Thanks for all your help so far I have had a fantastic response from you guys and think that this forum is priceless for someone like me with no prior knowledge of these machines. However the danger of the price and availability of these machines without any knowldege on my behalf has been brought to my attention by the last post of PaulC who may well have saved my life. Thank you!

The company which I bought this machine from are very helpful at the moment and are taking me step by step through what could have gone wrong so I will keep you posted.

This well could have been caused by the cracked laser tube which I believe was done during transportation (no fault of the company) as the water cooling tubes had water residue in them, which would say to me that the company which sold me this machine had kindly checked that it worked before sending me it.

This is trial and error with me at the moment so thanks for your patience. I can be PM'd if you have any info for me or would like to check if I am legit.

thanks for all your help.

The HV probe as suggested by PaulC is a must for checking high voltage.

Please make sure you follow the instructions that come together with the probe - especially the earthing for the HV probe ... when you are using it.

Also make sure the earthing on the engraver is also done properly.

Hopefully you have already ordered the laser tube and the power supply in for the repairs.

Hello Mike,
Welcome to the zone. Are lasers your primary interest or are you like most of us here, interested in almost anything.

Hiho chaps (and Ladies if applicable)

I'm looking for opinions and experiences in using/buying these China made laser machines.In particular does anybody have any recomendations of what far eastern company to use? they all seem to be much of the same price wise for a 40W laser so does the company selling make any difference? also can I ask about the china Ebay sellers? is that a good way to buy (I can't find any distributors in the UK)I'm looking to buy ten machines for short term production work and ten the same will make it much easier to oversee.
Any advice welcome from experienced people or owners of these things.
Many thanks for reading.

Could I please respectfuly ask though that any manufacturers reading this DON'T bomb me with offers of machines or prices etc,it will not achieve anything and will simply result in me blacklisting you from being a potential seller no matter what deals or prices you offer.

I did note that somebody commented on the command of English displyed in the Videos on utube,sure it's not fantastic however you really wanna hear my Mandarin Chinese..now THAT is BAD

best wishes from the UK

There is a guy representing Red Sail in England.
Read back through this thread. I think his name was Neil.
I would seriously talk to him.
Support is the biggest issue with these machines.
So many of them don't work on arrival.

Thanks Paul,

I'll see if I can find him
