Next Wave CNC Shark HD3 Accuracy Problems
Posted: Wed Jan 27, 2021 2:32 pm
Hi everyone!
So I have had my HD3 for five years now. I have not used it much. I mainly make gifts and signs, etc. I have the latest vCarve Desktop software and the Control Panel 2.1.
Anyways, I have been increasing frustrated by the quality of the cuts/finish especially in flat areas which exhibit significant tool marks in what are suppose to be flat areas. Strangely 3D images cut very well, gorgeous in fact. I just need to get flat areas to be flat. I posted my concerns on the Vectric Forum first https://forum.vectric.com/viewtopic.php?f=2&t=36565
To test the accuracy of my HD3, I created the attached vCarve file. I created large .10 deep flat areas on the left and right with a 1/4" End Mill. I then created nine boxes in the left area with the 1/4" End Mill starting with .11 deep, actually .01 below the large .10 area, then .12, .13, etc down to .19. The right area uses a 1/16" Tapered Bull Nose for irregular shaped areas, each .01 deeper than the previous. Note that I recently trammed my machine and flattened my spoil board and the results were excellent. The large flat areas on the left and right were smooth with very light tool marks, but strange edge conditions that I cannot explain.
I have attached the vCarve Desktop CRV file and the 1/4" End Mill TAP file converted to TXT and 1/16" Tapered Bull Nose TAP file converted to TXT. The photos are in the subsequent post since it appears only three attachments are allowed per post...
As you can see the results are horrific. I understand that the HD3 is an entry level machine that uses a plastic carriage, but I was hoping that shallow areas would be cut accurately but this appears not to be the case. Even the .01 deep areas show tool marks, progressively getting worse as it gets deeper. I suspect something is wrong with my machine and hopefully someone will be able to either suggest how to fix this or what, if anything, could be wrong with my HD3 OR suggest hardware improvements that would increase the accuracy of the HD3.
Thanks for you help! I have asked Next Wave to comment on this and sent a link to this post to Scott at Next Wave.
