OK, it really was moving the cross slide over by the diameter of the part instead of the radius. I didn’t find an option to switch it over to radius so instead I changed the setting for the X axis to .1″ per revolution instead of the .050″ per rev that it really is. Seems to work fine and as a bonus, the DRO for the X axis in Chilipeppr still reads out the diameter for me. I even was able to make something with it today!

bracketracerMemberI had a chance to run it with the changes. Just cutting air, it moves like I expected it to now, no blue swirly tool paths in the corners so that looks much better I think. Almost ready to try making something but I would swear that it’s moving the cross slide over the diameter of the part instead of the radius. I had to leave for work so I’ll have to check it out later.
Thanks for the help!
bracketracerMemberOK, so in the “fanuc turning.cps-Generic FANUC Turning” post processor I was using in Fusion 360, line 35 reads “allowedCircularPlanes = undefined; // allow any circular motion”. I switched “undefined” to “0” and it gave me a Gcode with no G2/G3 codes. I already had smoothing turned off and make sharp corners turned on. Haven’t tested it yet though.
bracketracerMemberMy plan is to keep it simple and make the spindle the Z axis and the cross slide the X axis. I tried to air cut a simple cylinder shape this morning and I really thought it was going to work until it came to the edge of the cylinder. It was at that point that I was able to understand what the “I” codes and the “K” codes in the Gcode did! LOL. I should have Googled those ahead of time I guess! I’m not sure why the post processor added those since the tool path in Fusion’s CAM looked correct. It made a little circular flourish at the corner which would have left me with a cove-shaped corner if I had material chucked up instead of the sharp corner I drew.
I need to work on the carriage slide of this lathe also, it’s new and a little tight so it stalls the Z motor often. I have the motor removed and laying on the bench while I learn the programming.
bracketracerMemberYes, that is my post over there. I was hoping to hear a success story since I couldn’t find one on youtube. lol
