Hello everyone,
I am at a factory that has a no-name Chinese laser. It uses LaserCut 5.0 drivers. The laser is a 60 watt, glass tube, air, and stepper driven.
I have some leather that I cannot cut no matter what settings I use.
The types of leather we use are vegetable tanned (tooling leather), oil tan, and chrome tan.
The veg tan and the chrome tan cut fine.
The oil tan, whether it's 1.5mm thick or 2.5mm thick, will not cut. The laser will blister the surface and that's about it. If I do multiple passes then sometimes it will make it all the way through but not without significant damage to the leather.
After searching the forum it seems to me that I might be able to do something with the PPI. I know what this on the Universal we have but have no idea how to adjust it on the Laser Cut software. I found something called Pulse Unit and something else called PWM. I think the Pulse Unit is the PPI but it requires some calculation and I am not sure how to do it.
Here are two screenshots - any help will be rewarded with heaps of karma points going your direction!!!
