Re: Lightobject new DSP laser controller card

For K40 yes it is 300x200
What micro stepping are you using?
What UM?
Again, you better post screenshot of your seeing. It will help me trouble shooting better

Re: Lightobject new DSP laser controller card

Did you set up the work area correctly?
If 'UM' is too far from the correct value, the range of work area could be affected in multiple scale

We used the T9 on our 2500x1400 and 900x600 machines
It can't be hardware issue

Re: Lightobject new DSP laser controller card

Hi So I'm pretty new to Lightobject, so forgive me if I am posting to the wrong forum. I bought the T9. I am doing a lot of engraving work of pictures and this looked to be the best solution for my K40. After a ton of debugging with tech support, the machine is alive. I am having 2 problems now. 1)...

Re: Lightobject new DSP laser controller card

I just talked to the manufacturer and they could provide either 1.4M or the2.4M. I tried to get something in between like 1.7M but not available. They sent me 50x cable for spare but you need to install it manually

Now they are working on plugin for the controller like the Inkscape

Re: Laser Head Question

I'd to use 50% alcohol(91%) + 50% acetone Then use a cotton ball (better to have de-grease ) or quality lens clean paper. Do not rug the lens but apply pressure gently with your finger and move in half circular motion. Do not over-lap with the same cleaning paper or cotton but use a new one. So, one...

Re: Laser Head Question

Yes it did. If you rug a little harder on the lens or mirror with a cotton ball and alcohol, you will see scratches.
If that happen, beam spot may be diffused and cutting power will be affected.

Re: Laser Head Question

Sorry but I have to disagree of using a toothpick trying to touch the lens. The coating of the lens is easy got damage. Even smoke on the surface of the lens will affect the output cutting power! Simple way for us is to fire laser at lower power and find the tiniest spot. Or, you can burn a line in ...

Re: What Stepping Motor Driver Should I buy ? U-axis . . .

We changed it to 3 phase motor because all our laser machine are now using 3 phase. I will have to correct the item description, thanks for the info

Re: What Stepping Motor Driver Should I buy ? U-axis . . .

You can get 3MD560 or 3MD580, any 3 phase motor driver capable to supply 4A or more current would be fine

Re: 3MM Baltic Birch Ply

Strange!
We tested it before shipped

Could you download a simple file like a square box?

Check the memory of the card and remove all files then try again

If it doesn't work, check connection of wires in the controller because it may got lose during transportation

Re: 3MM Baltic Birch Ply

Try 6mm/s on each corner see if it cut through. If it does, then try 7mm until if can't cut through then tuned 1mm/s less to ensure that it cut through everything on your project Remember that the sample must at least 25mm long rectangular but not small circles like because it take time to speed up....

Re: Raycam and Rotary on U axis

Look, I didn't promise anything here. I only made suggestion to the programmer what feature(s) should be added to the software to make the card be more powerful. I made a wish list and posted on this forum if you remembered. Again (same old..), I was not the programmer and I made no guarantee how ar...

Re: Raycam and Rotary on U axis

BTW, I don't think you have to swiitcj the UM fromY to U. You only need to do one calibration for the U axis and stick with the same UM regardless what size of the cylinder object to be used. On the LCD there is a setting where you can just input the diameter of the object and get the rotary to work...
