Lines in engraving

Post by closeracing » Sat Jul 08, 2017 2:08 pm

Can anyone tell me how to get rid of these lines? I am now using Corel photo and RDworksv8. Resolution is 1500, frequency is 70 lines per inch,net graphic dithering. I've been struggling with image quality and would sincerely appreciate any and all helpful advice. Thank you!

Interval must be equal to 25.4/DPI of your photo
For example for a 300dpi photo must be 0.0847.
Also not use net graphic use dot dithering.

Blondie123 are you using RDworks? If so you might try changing your cut and sweep parameters to the settings in these photos. It seems to be working for me.

Also do not use net graphic for dithering. Use an outside program like photograv if you have it or try dot graphic in RDworks. Net graphic is responsible for the lines, improper sweep parameters are likely the cause of poor quality

This is my first day on the forum and I though I would hello. I bought a micro mill I am converting to CNC and was told this is the place to be. I look forward to bugging you guys with novice questions.

Hi everyone ,

Does anyone know how I can detect Double lines in an TS model?

I guess SelDup or SelDupAll is not the wright way for TSshapes...?

Is there any way to remove the lines which correspond to margins, etc. from around text when in full page view?
