So true. Spindle speed and runout are very important. I have good results at 20krpm but feed rate is limited by the spindle speed. 30krpm would be better. > 2.

Maybe I never found the right material to print on. I only tried a couple times. ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
