Wavy Cuts and Bad Etching

[waltfl]

hi there
just post the file and let me try it.

I have tried both of your settings and it didnt change a single thing. I have looked at the voltage to the controller and it is spot on at 24V. The Controllers and laser both have correct voltage. This problem has to be a bad controller. I am attaching a photo to show many more failed attempts at cutting with this to show that is it not consistently the same bad. If there is a way i can fully Reset the controller and/or Fully Flash the Firmware on this please let me know.

I doubt it that is a faulty DSP controller. But if you want to, you can send it back for me to test it. If is defective, I'll ship you a new one for you. But if not, you need to pay for the return shipping cost.

Send me order# and I'll issue you a RMA#

Tried that Falling makes the cut A whole lot worst.

Try changing the pulse from falling to rising in the motor section.

Do you want the Corel Draw File or the Laser Cad Output file.

I am running LaserCAD V6.71 but see in he forums that someone asked about LaserCAD V6.81. Also is the firmware correct on my controller(attached is photo of screen). Also is there a factory Default that i can go to that might fix this problem?

The OS is current. Even if it's old won't give you any trouble like that

I am at a loss of what could be the issue. I have done everything you have said as well as looked for any wires that could be interfering with each other. The machine had no physical problems before but now that i have pulled old controller and installed the new one it does not work at all.

You may not believe that this week two customers returned two DSP one said that it was not engraving well and another one said that the card made the machine running abnormal and not responding to home switches. A replacement card sent to the customer for testing and ended up the same and the customer confirmed that it was not the card issue. The second case was not even a case as it ran good on my testing (just tested it 20min ago). I couldn't duplicate any issue the customer had reported. Just let you know that in most case it won't be the DSP card but it is always the 1st place to be blamed. The defective rate of the DSP is lower than 1%. From my experience, most issue were caused by other components on the machine. Pulley, drivers, motor, wires, USB cable, DC power supply, grounding, shielding,...

As I mentioned, you can return the card for testing. The card can't be 100% defective free. If it is defective, I'll replace it with a new card. If not, you just pay for the return shipping cost. What you need to do is to send me a job file and I'll do some test on my machine. Then, I shoot you either a video or picture to verify.

Please no hard feelings...
Personally, to me it does not look like a card issue. It would be very hard to believe that the controller would interpret data that way if it was faulty. It looks like mechanical issue to me. Firs thing I would go after, would be the head lens and make sure it is not lose and vibrating while head is moving. Secondly I would check the head for play in the slides or roller or whatever it uses for motion mechanism. Belts and tensioners, motors and bounce mirrors. And lastly I would check for stepper drivers compatibility and correct settings. I had a similar problem long time a go and my problem was the head focusing mirror was lose.

This may not be your case but it is worth to review and hopefully you find the problem eventually.
Please make a video of the machine while processing a file and let us see it to analyze it. Take care and good luck.

I have looked the machine over very well today checking mirrors belts bearings slider rails as well as to see as slop in the X and Y axis thay wont move a hair. The Motors as well as there controllers are matched and worked on Monday with the old controller that i had installed. I have made a video and posted it here for you.

Hi there
first try: turn your air assist of
second : check your nozzle it looks like that your beam gets interrupted from hitting something inside the nozzle or head
if you watch the beam circle you see how it gets interrupted.
check if the beam hit the head mirror dead on center.
this is for sure not a problem of the DSP.
don't let you foul if it worked with the old sometimes things like this can happen even without changing parts I was there.
the most reason I found was not perfect aligned beam, lens was loos, or the beam did hit somewhere inside the air assist nozzle
I hope this helps maybe

Hi lasergoodies,
I reviewed your video over and over and I still fall in the conclusion that there is a problem with one of the lenses. If you look closely the head does not follow the crazy wobbly lines, instead the focusing mirror inside the nozzle is moving and directing the beam to the sides after bending a corner.
I'm sorry this is happening to you and I truly know how frustrating it can but hopefully we can help to get you going soon if you are willing to do more test for us.
A better way to see if the mirror is lose would be to decrease the speed to a very low setting like a 5 or so. Also reduce the laser power to around 8% to prevent over burning. If you don't mind making another video while running the test and submit it to us for review.

Thanks everyone that has helped with the problem i went and took all of the lenses mounts out of the machine and made sure every bolt and pin was holding it tight as well as took the head off of the machine cleaned and tightened all of the bolts i put it all back together as well as aligned the machine to find that it is working great and dont not move a single bit.
