Dear madam, sir I am user of K40 laser and I am using Moshilaser software with Corel Draw X6. When I draw object (with exact size , e.g. 20x20mm), then when I burn this piece I would like add some fixed offset to reduce kerf . I tried to set FixedAdd (I tried values from 0.5 to 5mm) to add this size to burned shape. But this solution does not work. Can you help me with my problem ? Thank you so much. Best regards, Attila Csontos Slovakia, Europe.
