I’m a new owner of the shapeoko XXL and have been tinkering with the software. And noticed that in carbide create 4.0 when setting up my material I only have 4 to choose from. Aluminum hdpe MDF and one other. But looking at videos and tutorials I see that there are loads of materials in this drop down list.
I have tried reinstalling and to no avail I still only get the 4 materials.
Any advice on how to fix this?
This is the result of Carbide Create changing from calculated feeds and speeds to a curated set of feeds and speeds which are still being tested/developed, and are being released with updated versions as they are ready.
For speeds and feeds with a 1/4" endmill please see:
(there’s a row matching dial settings to RPMs at the bottom)
There’s an interactive version at: https://public.tableau.com/profile/willadams#!/vizhome/Carbide3DCNCFeedsandSpeeds/Sheet1?publish=yes
See https://www.youtube.com/watch?v=S9bceJxpqG0 for concepts on this and see the series #MaterialMonday: #MaterialMonday on YouTube for specifics.
You should test feeds and speeds in a piece of scrap using the technique at: https://precisebits.com/tutorials/calibrating_feeds_n_speeds.htm
Another consideration is Climb vs. Conventional Milling and tooling engagement — where possible avoid slotting and add geometry and cut as a pocket (Adding geometry to cut as a pocket with a finishing pass ).
Extensive discussion at: Origin/consistency of chipload recommendations and https://shapeokoenthusiasts.gitbook.io/shapeoko-cnc-a-to-z/feeds-and-speeds-basics with a spreadsheet for this at: Speeds, Feeds, Power, and Force (SFPF) Calculator
I love the idea of the tool library and the control it gives us. But I don’t like the fact that we are on our own to to figure out speeds for hardwood until this version of the library is available. I would have like to see your version 1.0 published and then tweaked as necessary rather than all of us coming up our best guesses. Perhaps you should have kept the old method as an option until all materials are available.
Any idea when other materials will be available?
Build 451 is posted right now with those added.
