Hi all,

can anyone help solve why this cut occurs ?
it was a pathcut of acrilic 3 mm with 11 mm/s 75% of 80 watts power (with i believe is too slow and too powerfull for 3 mm acrilic) . why this dots occurs? if i slow down the machine they dissapear. Could it have anything to do with frequence ? what is the frequence ?! i still have no help of the chinese factory (they say they are in a sales event). Have no software manual, and there are TOO much variables in the software windows...

Thanks a lot... we will take good care of your president tomorow...

the problem..

187223 187224

the software configurations, that could be the cause ?! (pulse frequence ?! pwn frequence ?! what are those??)

A laser cuts by drilling holes basically. The frequency tells the machine how many holes to punch in a given area. It appears you have your pulse frequency set to 0. The photo looks as if the frequency is too low. I do not know how your frequency settings relate to mine, but Epilog recommends 5000 as the frequency setting for acrylic. That might be an overkill as I can get a pretty good edge with 500. Start with 500 and go up and see what happens.

thanks a lot...

this could be very related to the DPI settings i alwayes read abaout in this forum... i will check by starting with 500.

if anybody has more information, i would thank a lot.

DPI is not related to vector cutting, only raster engraving.
