    Angry Ruida RDC6442G problem

    So, here is another problem got on my laser machine...

    In the middle of a cutting job, i looked at the machine lcd, to see job time... screen frozen... ok, i said... let the job finish, then, reboot the cutter... happend once or twice... after 20 minutes i did that... machine rebooted ok, but the controler LCD all white... weird, but wtf... it's made in china, so ****s happens... power off, wait 10 minutes, and power on again... and still in the same condition...

    The laser works ok, but the LCD is all white... no image, no nothing... just a white light... the buttons are working, the laser is working, but no image on the "wonderfull" full color lcd...
    The controler is a RUIDA RDC6442, on a laser engraver used about 300hours in 10 months... 3rd bad problem i get since i bought it...

    Question is: i can change just the front panel? or i can find a better controler even if it's more expensive?
    do i have other better alternatives for controllers than ruida ?

    the rouida controler is mounted in a 1200x900 laser engraver with a 80w RECI tube...

    Thanks in advance for any construcive advices

    Hi Michael

    you can change the panel. it is not a big problem

    Ruida is as good as Leetro controller.
    it is not necessary to change another controller

    its not the reboot, try wiggling the connectors - the quality of parts is such that the contact is intermitent . i didn't have ruida controller , but it seems it is quite common issue. after i find a good position display stays connected for some time.
    the consolation here is that the front panel is not nessesery to run the job and machine can be commanded from PC . its anoying, but works

    thanks all for your answers...
    for the moment, i made it work... some isopropylic alcohool, a tooth brush and it's ok for the moment, but i don't think it's a permanent fix...
    Nolan, what is THE BEST controler for a laser machine and what it can do better than ruida?

    Hi,
    I bought 50w laser machine made in China and it has the RDC6442G. I have used it just for 3 days and it started giving problems. It shows the files in the memory but no pictures and and after few minutes,it shows 'No device connected'. The led number 14 flashes. Do you please have any solution to the problem. I have contacted the seller but no solutions and I even ordered another controller and still the same thing happens.You can check my Youtube videos to see. I have done the factory reset after making the video but still the problem remains.Please help.



    Regards

    Pillar

    according to our testing, we think Ruida controller is best one in China, if you need to buy chinese controller, Ruida is still a good choice...
    for us, we will testing the controller stability before we sell it to our customers, but we still can't 100% promise that it doesn't have any problems in future, what we can do just reduce the defective percentage.
    Have a nice day.

    Hi,
    Thanks for your ideas. I have everything checked, they are all ok.Everything works fine but it's just that it does not display the programs and does not run them either.

    Hello Pillar,

    please be aware, that a hardware controller has only a limited space of memory available (i think the RDC6442G has 128Kb). It could be that you simply run out of memory what might causes a problem then. (do a factoryreset on the controller and try not to fill up the controler anymore)
    If the machine is hooked up to the computer directly you do not need to store your laser files directly on the controller, instead you could fire them directly from the computer.
    Another solution would be to work from a UBS stick that usualy has GBytes of memory today.

    best regards,
    Walter

    I have this controller installed in my laser engraver and I have a question regarding the LED indicator lights. The pdf manual doesn't describe what the led indicators are telling me. My led indicator light 14 is blinking and will not allow the laser to fire. Can you tell me what indicator led 14 is signalling please? Thank you for your assistance.
