Im currently working on a project that requires cutting thousands and thousands of little pieces from a roll material using a 40w galvo laser from Haotian.
Up till now, the material was supplied in sheets which i made a rotary table jig to process these materials, however it will now be supplied in a roll format
I have an idea of using the Rotary chuck to wind the material and use repeat marking to process this material.
I was wondering if any members here have tried this? And wouldn’t mind sharing their setup.
It would basically mimic machinery such as these but on a much smaller and economical scale
If you search the Forum for conveyor, you will get a pretty good idea on what has been accomplished so far.
Considering neither your machine nor Lightburn were designed with this in mind, be prepared to experiment on your particular setup. From what I have read, it can be done with a little effort.
That’ll work (with a bit of effort), and similar workarounds have worked in the past when pairing grossly dissimilar NC and CNC (router/lathe)- and automation protocols together.
A few lines of code at the end of the work cycle moved the toolhead somewhere on the work area, and tapped a switch or tripped a light fence.
What ever task that switch activates and performs, has to have a somewhat intelligent feedback to the CNC machine in turn, to start the next machine cycle safely.
This is mass manufacturing automation type of a situation, so something will go wrong, sooner or later, so best to cover ones behind as thoroughly as possible.
While mechanical switches are virtually foolproof when chosen correctly, with lasers I’d probably choose a photosensitive device that the (low power) laser beam hits at the end of the work cycle.
With photosensitive devices, one can have as many different “triggers” for various tasks as one wants.
Something like that will also work with any type of laser the photosensitive device is sensitive for.
Visible spectrum diodes are obviously very easy in that regard, outside the visible spectrum the selection might be more limited.
If the laser power can’t be dialed down (CO2) or attenuated (with filters) enough for a reasonably priced photosensitive device to last more than a blink, a thermal device most likely works for that task as well.
