Surfacing test on pine wood was successful. Used a smaller 1 inch surfacing bit. I also straightened up my gantry a few months ago with dial indicator recommended by Winston. I also adjusted the stepper motor steps, which I didn’t test. But overall really happy, there are absolutely no lines at all on smooooth baby’s ass surface. Used 25 percent stepover and used rhinocam to for 2.5D facing operation. Offset the top surface by 1 inch with .01 cut depth. only 1 pass, 18250rpm (dial3 on carbide router). Had to set the datum on machine manually, couldn’t use the edge detection tools because of the surfacing bit.
This will be helpful especially for the warped hard maple neck blanks I purchased. I think I have like 20 of them. I’ll surface those next.
Bad news though for the frets slots in Rhinocam. The Shapeoko machine doesn’t support R modifier commands when using the G2/G3 arc commands. Unfortunately lining up the I, K modifiers was a failure, they just wouldn’t line up correctly. I even contacted Rhinocam, said exactly the same thing. Not sure if I can accurately model with I and K modifiers, it kept getting offset crooked, even got mismatched arcs errors in Camotics. So all is not lost, I can still generate the segmented linear code from rhinocam.
Other good news, I had to edit the Rhinocam post processor, the main issue was it being locked to 10000 rpm. I edited the min/max and also tried to mimic the syntax from carbide create.
I uploaded below just rename txt file to .spm and paste into C:\ProgramData\MecSoft Corporation\RhinoCAM 2018 for Rhino 6.0\Posts\Mill
The good news is the post processor can be changed from g90 absolute to g91 incremental. I could have done this in Gcodewizard but really happy it is a cool function in rhinocam, was trying find the command somewhere, haven’t ran a test cut just compared the coordinates from both files and it looks like they changed to relative, could be wrong though. I’ll run tests. This would allow me to make doublesided projects easier. Only having to setup from 1 axis and able to use tape to workhold pieces to allow better cuts along profile. Overall, really happy with Rhinocam, right now I am using an older not legit version but will purchase the full version from them once I start getting rolling. The new version has gcode editors built in a few new features but I still should support them but it’s 2750 a year or 5000 for pro version. It works so great with Rhinoceros.
