I too purchased a redsail RS3040A

I did not find tech support that bad, in the end they helped me resolve most of my issues with the laser, although I did have to make a few of my own modifications to the machine to get it to work to the standard I expected.

The software is OK but could do with english support in the help files, although I did get great help from tech support via a webcam to demonstrate what was happening.

At first the cutting lens would move sporadically, even when pressing the test button. In the end I figured out it was to do with earthing the machine. I did earth it as suggested by redsail, but in the end I moved it closer to the distribution board, added a few cables inside the machine to earth the chassis to a better level and hey presto it stared working fine. and used a 2mm earth lead from the distribution lead to the laser. For some reason at higher powers the laser would go back to not performing until I placed the thicker earth lead on, I assume the high voltage from the laser PSU was finding an easier way back to ground.

The mirror adjustment screws where of quite poor quality, in fact 3 of them snapped. solution drill the old ones out, and tap new holes in the 3 main adjustment mirrors and place new brass screws in, now I can adjust the machine perfectly. As for the machine meeting CE standards, I would say no. The water cooled pump needed to be wired inside the machine instead of outside of the machine with its dodgy looking plug. We also made cut off attached to main lid to turn the power off should it be opened, and are considering placing a timer on the main power switch so that the laser will power up after 30 seconds to avoid tube damage from overheating.

The only consumable I've had to purchase so far is a fast blow fuse on the what I figured out to be the control curcuit for the lasers High Voltage PSU.

Given the price of the redsail machines I can not fault them too much, given my experience with the low end unit RS3040A I would suggest you perhaps try to make a trip to China to see the unit in operation (The price of the machines will justify the expense of a trip to look at various the Lasers from manufacturers in China)


Also replace the FAN if you have a RS3040A - the fan with any serious length of ducting (over 5m from my experience) will start blowing fumes from the back of the fan, not nice if you are engraving rubber stamps, or cutting materials you should not be like vinyl.
