Hey folks, I'd rather not recreate the wheel here. I'm hoping someone else has this CNC machine or a similar grblHAL machine with a 4th axis that can help me out. I'd love to get a working 4 axis machine standardized for the Fusion machine library. I am using an older PP that allows me to create the gcode I want. I haven't tested it as I'm still building the rotary Y axis trunnion, but the gcode looks solid. I also have taken the Altmill 4'x4' 3D model and tweeked it for the machine building in Fusion and it looks great! If I use the generic machinesimulation.cps Fusion file for the machine I have built in machine builder, it simulates my CAM perfectly. In short: - I can output good looking gcode of my 4th axis rotary CAM for the Altmill using grbl6axis B axis.cps, which I found on a forum. - I can simulate fine with a 3D model of the Altmill I built in Fusion's machine builder space. - I'd like to marry the two into an Altmill multiaxis cps file that works for BOTH CAM simulation and post processing gcode. I've tried editing the grbl6axis B axis.cps as per instructions here: https://www.autodesk.com/support/technical/article/caas/tsarticles/ts/6gt1MMvoyp6qGZzNScavq1.html But, I'm not savvy enough to navagate the javascript between the two files. I don't get very far before encountering the now dreaded "invalid post processor" message when trying to apply the cps to the machine. I've attached an image of the Altmill with 4th axis trunnion setup for clarity and the grbl PP I'm using to get clean gcode. Any help would be much appreciated. Cheers!
