Questions about changing plunge and feed rates, just wondering what a good maximum is for bits, i notice when i change the rates it increases the project speed which is great, but what rates should i expect that things will start messing up or bits breaking
The rates that Carbide3d has calculated are supposed to be middle of the road for the material selected. You can always change them but what is the big hurry. If you are in a production environment I can see saving a few seconds per widget. If you are just making hobby stuff the risk may not be worth the reward. There is always a risk/reward to every change you make. The only way to evaluate what will work or more importantly not work is to try it. There is no one answer because there are a lot of variables. Some of the variables are the wood type used, even the same species can be harder or softer than the trees harvested around yours. There is your aversion to risk. So the values that Carbide3d have put in are safe and will work. Anything else and you are on your own including using their suggestions because every variable makes a different outcome.
So if you want to go faster you will need to increase in increments until failure or you are satisfied with the results. I have found that Carbide Create estimates almost twice as much time as actual carving. When you load the gcode in Carbide Motion it gives an estimate but that estimate is for cutting and I dont think it includes the retract time, rapid moves, changing bits and going to t he BitSetter. So even what Carbide Motion says I would estimate about 20% more time but again the only way to be certain is to run the job and time it. If you are making the same thing over and over you also have to add up your time to remove the project, replace the blank for the project and the time to hit start.

Yeah something i will have to play with for sure, was just wondering what speeds you wouldnt recommend changing them to like 100 feed rate and 80 plunge rate
Plunge rate is usually less critical for project time (if it is you got likely retract height wrong) and often not great to tune too much… end mills are optimized for horizontal not vertical cutting.
The feed rate there is often room… what I do is start conservative and use the speed controls in carbide motion to go faster… if it works/sounds well next time I go faster in the tool paths themselves.
