In Fusion 360 … I am having a had time finding out how to adjust settings such as lead in radius, lead out radius, whether or not to use tabs, and what to use for heights. I am cutting with a razorweld 45 and we have a crossfire.
Some of the problems we have are getting the torch to fire and start to get a smooth beginning and ending of the cut. Also, we are not sure if some of the heights in the program are messing up the mach3 postprocessing … causing our torch to fire weird (starting and stopping, not cutting all the way through, etc)
My question is … how can I set myself up for success when cutting on the fusion 360 side of things?
Hey Cody!!
Well, your lead-ins and lead-outs are a function of starting the cut on a part a bit away from the toolpath you’ve selected and “easing it into” the line you are trying to cut… Usually the smaller the cut out will be the lesser your lead-ins/outs will end up being due to the space available in the “waste”… You can play with those numbers when generating a cut path as you see fit. The bigger radius you choose and shallower angle you choose make that transition more gradual…BUT, you may not always have room for all that.
You would use tabs if you are making a cut that you don’t want to fall out as the cut completes. Possibly avoiding a tip up getting in your way for a later cut… I guess another reason to use tabs would be to help things in place while the cut continues. Though, most of the time you take care of the small stuff before the big cuts or outline thus keeping things where they need to be…
Unless you already have “THC” or a “Z-axis” the height you cut at is determined by the plasma cutter and how it best cuts. Most are using the “small shim” provided with the table… Doesn’t always work for all… The small shim would be a good place to start…
Starting and stopping on cuts could be a number of things… Tell us a little more about your setup. What are the settings you’re using now for pierce delay… material you’re cutting…Amperage…Air pressure…feed rate…etc. etc…
The “not cutting all the way through” could also be a variety of things… But, amperage at the cutter and overall cut speed could be culprits… Are you getting a complete “pierce” at the beginning of the cut?
Do you have some pictures to show as examples??
Maybe some others will chime in with thoughts as well… You’ll get 'er goin!!
