Hi all
today i attempted to engrave onto anodised aluminium with mixed results. i engraved a gradient so that i could see the marked/unmarked parts and get the optimal DPI for my machine (boxford BGL 690) i used the settings in lightburn for anodised aliminium as a starting point. the mage came out but with a usb microscope i was unable to see anything remotely usefull (see image 1)
i also tried a conventional microscope with no joy, i was hoping to see a line of dots and unmarked area’s to refine the dpi settings
as i had a stack of cards i thought i’d just try one with an image and see what happens. i set the dpi for 300 with a line interval of 0.8
when i start the burn from the machine it works ok
also the asign function for anodised aluminium no longer gives me any settings? do you have a setting as a starting point for this?
cheers

It’s mechanical… check both pulleys, usually a grub screw holds them in. Good solid mechanics are a must… so check over anything that needs to move that it’s movement is secure…
I did the test, spoke to an engineer who said it might be the auto focus catching it, I used a lump of wood routed out 1mm to hold the card so it might well be that! Will have a look tomorrow
Will check the grub screws as well
I used the assigned setting for anodised aluminium, 300 i think
