LaserUser.com Forum (formerly RDWorksLab)

I'm totally with you on that. I sent them another two emails for follow up, one just a few hours ago. We'll see what they say this time.

So the PSU folks got back to me and told me to check two settings:

This phenomenon may be caused by the following reasons: the first reason is that the manufacturer's parameter selects the radio frequency tube mode, and the second reason is that the idle light emission/outside light emission is turned on in the user parameters.
Suggestion: The factory setting selects the glass tube; the user parameter turns off the idle light emission

Neither suggestion changed anything-- settings were already set to the recommendations.

So the only new data I have is that I attached a Cloudray LCD Current Meter to the laser PSU. I did a sample cut to see what it would read. When the laser should be firing (and IS firing), the meter reads 9 mA. When it's traveling and should not be firing, it reads 8 mA. After the cut is completed, if I press frame, it frames properly but also burns a very faint travel line and the current meter reads 1 mA.

I'm between adjusting the potentiometer on the laser PSU and it being a controller problem. The only reason I'm not convinced it's the PSU is that I had this problem before I put the new PSU in.

I've ordered a new controller. It arrives on Friday and we'll see if that changes anything. Other than trying that (not so inexpensive) test, I'm at a loss.

Update for any other poor soul who searches for these symptoms and finds this thread:

Three more exchanges with the PSU folks (who have been responsive and did their best to be helpful), I tried every test they asked me to do... And then I tried a variety of other tests...
... then I installed a new controller, wrote it over with my backup controller file and VOILA... Fixed.

I took the cover off the old controller. My husband says he sees a bad solder joint. I don't know that I can actually tell or not. I'm just glad it's fixed. My pocketbook? Not so much. C'est la vie.

Great to see that you have been documenting your efforts and results, and of course the resolution, some poor soul is going to be so grateful to you at some stage for sure.

Hi Guys,
Yes your post may come in handy, I have a friend who has a similar problem. If he presses frame 3 tines it will get through 3mm ply, so not so faint but similar. his also fires when going to origin. It was working fine than just started doing this. I have a spare controller , so I will hook it up tomorrow and see if it fixes it

Did this fix the issue on your friends last as I am haveing the same issue mine fires when I jog it from the Pc or when it’s moveing to the Origen or any rapid move
