It was cut using a 1/8” two-flute up cut mill at feed rate of 1000mm/min with speed “2” on my Carbide ER11 router. The length/size appears to be good. Dog bones and inside corners didn’t come out clean, but it will fit on the gantry brackets as-is.
I’d check the core for wobble and whether the endmills are the diameter they say they are. The holes and corners seem to be way off. The struts should have a good fit for them to be really effective.
Thanks for the advice. The holes actually cut really clean. I use Carbide Create for the CAM and the holes were cut using 20% ramping at only 300mm/min feed rate. The outline was cut at 1000mm/min which I thought was reasonable, but maybe I’ll try to slow things down and see if it comes out better?
Or…maybe I should try again using Kiri:Moto instead of Carbide to make my tool paths? I do everything on Mac computers, so Estlcam isn’t a good option for me without buying additional software.
When you say “check for wobble” what do you recommend I check specifically? Thanks again.
Thanks for the suggestion! The mounts for the router were tight…but when I put a socket on the core nuts to check how tight they were on the top rail they were completely loose. After double checking everything I cut a test rectangle and circle and they came out to <1mm accuracy. I’ll continue to fine tune everything when I get the strut plates cut and installed.
I then made a test piece using an end of the front strut plate, and the fit appears to be good. These photos are showing it on top of the existing temporary plate and hardware:
Any last thoughts before I cut the plates and attempt to install? My biggest fear is taking the machine apart and having the plates not work and then having to re-install the temporary plates to cut and try again. Thanks for the help!
I’m using Carbide Create for CAM on a Mac. Keep in mind the photos of the test strut plate are me holding it on top of the existing temporary plate and hardware. CAM settings were for 1/8” two-flute up cut mill with feed rate of 700 mm/min and 2mm depth of cut.
