Has anyone figured out how to configure the Fusion post processor for the 8L when you have a tool approaching from X- (the far side of the part)? I made a gang tool plate that puts one of the tools on the X- side, and then configured the tool in Fusion to be “Turret” 103 according to this Autodesk help article, but the resulting Gcode only comes out in X+ coordinates, and in the Gcode comments says “; Tooling: Quick Change Front Tool Post”.
I’m guessing that the standard 8L postprocessor for Fusion doesn’t know how to handle anything on X- nor Turret 103.
I think I figured it out. As I suspected, the cps file was hard coding to the front Quick Change Toolpost. To enable gang tooling, make a copy of the .cps file, then change line 725 (according to my cps file) in
function ToolingData(_tool) {
from:
var turret = model == “8L” ? 1 : _tool.turret; // 8L only uses a QCTP on the Front
to:
var turret = _tool.turret;
Then in your tool definitions in Fusion, you can set “Turret”=3 for X+ gang tool, and “Turret”=4 for X- gang tool. (3 and 4, not 103/104, if you look at the code.)
At least I think. No guarantees implied, your mileage may vary.
In Mastercam you go into tool properties and change the tool orientation. When the program brings the tool in from the bottom instead of from the top the software automatically post code from X-. That is how I post code from the quick change toolpost positioned below the part and turret tools above the part in the same program for the 15L.
I’ve confirmed that my above change to the Fusion post code for the 8L has the desired result. It works great now. There is no provision in the Fusion post processor for tool orientation.
I am using the generic fanuc post processor. I edit the posted code by removing all of the non Tormach compatible speed and feed codes at the beginning and the go home g codes at the end. I replace them with the Pathpilot speed and feed and go home codes.
I was hoping to find a Mastercam post made for a Tormach, if not that is what I was going to do. Could you let me know which Fanuc post you are using? That would give me a good starting post. I have compared some post with the gcode Tormach generates from conversational and what Fusion post out. Looks like the s commands are different and I am kind of worried about trying threading.
