Had a good day today cutting four flat signs with the niece. She drew a flower in inkscape and we did a line following operation set up with krabzcam. And a .25 in bit.
. Next two were a computer drawing from a friend. Traced the bitmap in inkscape. Pocket cutting with Krabzcam
25 in spiral upcut bit. . Went very well krabzcam is cool. I learned how to edit the svg lines there to make enough space for the bit to get through some tight parts. Cut twice in particle board from old furniture.
Finally switched to a 60 degree .25 in v shaped bit. Typed a friend s business name in inkscape. Converted text objects to outline paths. Uploaded to krabzcam. V operation cut very cleanly. Tiny wobbles and visible distortion on circles. Not much. Very clean and fun engraved words. 3 mm deep. Took an hour. Took three passes. Could probably go deeper in steps. . Made a dumb mistake and didn’t set z properly. On the plus side the .25 upcut spiral was able to cut all the way through 18 mm IKEA particle board in a single pass at 400 mm per minute. Zoom. Going to redo it tomorrow.
Take aways from today.
Fast fold up frame continues to work really well.
Letters about 2 inches high cut great with 60 degree v bit and v cut in krabzcam. Fast low setup time and fun. Cut looks good cutting in reused plastic coated flat pack particle board .
Fun and fast for a kid to draw something then trace it with cutting
Trace bitmap of a computer sketch with pocket cut worked great.
Changing tools bits and setting z are still hard.
I can probably cut deeper and faster than I think. 18 mm particle board at 400 feed rate worked in one pass
I need to understand more about the different stop buttons. I keep getting stuck in situations where nether z jog or release tension work
Tomorrow trying the frame vertically letter engraving again with the v bit. May try beveling edges using a simple follow path operation before switching to a straight spiral upcut.
