Hey all,
So i am still trying to get this 4896 Zenbot CNC figured out to produce good quality cuts, i am currently using a Yonico 33210-sc 2 Flute Compression bit, i was using Amana 2 flute compression bit but was still getting same results and i am only getting 8-10 sheets of 3/4 melamine cut before it seems the bits go dull. Currently im running a Hitachi M12vc 2 1/4 Hp router and running at 100IPM at 11k rpm, a few questions i would to get help answered:
1. Since Compression bits are made to cut 3 directions should i be cutting the 3/4 MDF in one pass? Reason i ask is if i make three passes no matter what i only using the first 1/4in of the compression bit which would dull it very fast i'm guessing?
2. When cutting im getting rough cuts in certain areas, mostly corners are not
rounded it leaves hump before curve? Possible something to do with where the cut starts and stops? I noticed there very small wavyness to the cuts if you look close there not smooth
Inside Cutout as well leaving hump.
3. When i make my dado cut on the line it starts and makes a little swerve before starting?
4. I am not familiar with doing the ramp cuts and things, i currently have it plunge and start?
5. Circles are more oblonged than circle? Any advice on that?
I have been trying different things for a few months now to get it running smooth, time to try and seek advice from everyone. I have been looking around the DesMoines Iowa area to find assistance to pay someone to help but not much luck on the wood cnc machines.
Thanks
