It has been a while since I have posted an update to my Masso G3 enclosure build and 1F CNC modifications, but I now have something to share that may interest others.
With respect to the electronics, I have made my homing sensor cables, and added a relay module which at the moment uses the ES (Estop) signal from my controller and two of the relays to trigger the disable on my two drivers. I have also installed my second new driver which controls the 4th rotary (A, sometimes referred to as C) axis. I also installed an IR sensor to home the new rotary axis.
Hardware updates include the designing, printing, and assembling components for the tangential knife I created. The mechanics work well, and it configured easily with my Masso controller.
The final step, which I just today completed, was finding software to create the proper lift and motion direction angle. I learned that Sheetcam (used by many torch CNCers) had a Masso tangential knife PP. I was able to get a temporary evaluation license from Les, the creator (very supportive and helpful), and began experimenting. There were a number of PP to choose from, and today I must have got all the settings to work together because I successfully cut a paper silhouette (I am happy - it has been many hours of work from concept to creation).
I am attaching some pictures of the controller and tangential knife for those interested in a few visuals. Please note that 1) my 1F and controller are still in the testing phase, so please ignore the wiring that has not yet found its final path through wire duct, and 2) the file I chose to cut is, I feel, too detailed for this particular knife (I have plans to build an oscillating version with a narrow blade - but that will be much later).
