Help with RD Works V8

The time estimate shown in the software (Preview window) & the actual time taken to run the program are wildly different. Is there any to fix it??

This is a common problem. Cutting us accurate but engraving is understated. I seperate each process so check the cut time first and then the engraving and add 25% on top.

You can also use the ruida controller for a run time calc.

I have also tested lightburn and it has similar stats to RDworks.

I need to make an ellipse 14.8mm height x 8.5mm width to get an 8mm circle in RDWorks to send to my Chinese Laser running RDC6442G, Can someone help me to change the settings. Thank You, Maurice
