The Pass tolerance in the FUSION360 CAM operation "pass" menu MUST NOT be left at. It would be great if you could provide some feedback so that we can release it as soon as said you had issues with arcs? Note that there are properties for G53 positions to be able to set a tool change position.Īlso you have the option to activate your fourth axis (which can be mounted along X or Y). Together with Stepcraft we have made a specific uccnc post processor for stepcraft machines which is available here: CPS instead of.TXT as this forum will not let me attach at.cps !!!!!!!!!! WTF You can just put this post processor in a file anywhere, an in fusion, Post, click config file,m and Open from, and point Fusion to the folder, then you will be able to select this file from the option menu, Insteadd we manually zero'd x/y/z where we wanted them, clicked home all, normally moved the toll close to start point ( in that direction ) then clicked play We also disabled the first of the G28 commands as it would sometimes change our offsets, and go to the wrong part of the machine to machine parts. I normally run with soft limits off, as we use the center of the rotation axis as the Z=0 value as it is simple to place a sketch point in the center of your stock to select as the origin for z=0 I always view the A commands before they occur, and at the end of the last one, to make sure the machine isn't doing stupid stuff positioning wise. Above the A command, look at the last position for X/Y/Z, as this is where the tool will be, when the 4th axis is rotating to the new position, which you may want to manually change depending on what you are rotation on the A axis, Ie maybe move X left by 200, rotate, and then let the head continue with the passes. Once the Post has completed, view the post and search for A. In the post, between the two operations, there will be an A command, which is A axis. The CPS file attached, has the 4th axis enabled, which just means, if you create a single setup, and say two operations, If the second operation you click on the second menu, tool orientation, and move the Z axis to where you want the tool to come down from ( ensuring the Y and X axis are correctly assigned as if the part is rotated in the 4th axis ), then highlight both completed operations and ask for a Post. You need to set this each time you create a CAM operation when you check what parameters you have, and I increased it to 0.02mm without issues, if you see tolerance listed anywhere in fusion, it cannot stay at. ![]() 001mm, you need to increase it or else you will have an ARC error when you load the part in the UCCNC program. Some notes about how to ensure your CAM operation worksġ. I have attached the latest one I have, that is setup to be able to use the Stepcraft with or without the 4th "A" axis. ![]() ![]() Select your downloaded post and finish the process.I can see a number of people are requesting a Fusion Post that works with Stepcraft.Select the "Setup" buttom and make your selection "Use Personal Post Library".Add necessary toolpaths and start the post processing command.Navigate to this location: C:\Users\username\AppData\Roaming\Autodesk\Fusion 360 CAM\Posts.Open Inventor HSM, put toolpaths on your part then during the Post Process command select your downloaded post.Paste the downloaded post in this folder.Navigate to this location: C:\Users\Public\Documents\Autodesk\Inventor HSM\Posts.From here the process of getting the new post into either the Inventor HSM or Fusion360 library varies. Once you find the post you're looking for, click download and the file will download to your broswers download location. Also, you can simply type in what you are looking for! ![]() Here you can choose searching options based on machine type (milling, turning, cutting), machine vendor or look at the most up-to-date versions. Thankfully Autodesk has a searchable online library of posts that can be easily downloaded and added to Inventor HSM or Fusion 360.įirst, browse over to /hsmposts. Autodesk Inventor HSM and Fusion 360 come loaded with a lot of options for the post processors, but the post that you need may not be included in this library.
