I found an oddity with the 304 CC build after successfully using the workaround for the path names. I’ve successfully used my MAC with the Nomad through many versions of CC but after 304 two different anomalies manifested:
After successfully cutting with the first tool and then changing tools the RPM of the Nomad changed to a value different than my manual input value. I think it changed to the automatic RPM for the selected material (just my guess). I had set the speed to 6000 RPM and the speed was closer to 1000 (my guess). If I end the job, go back to CC and write over RPM and Feed inputs, disable the successfully cut path, and resave gcode it works well for the previously failed path, until the next tool change. I repeated this process on three different projects. Once a path works, through this process, it will work the next time I run it.
Unexpectedly the Nomad stops while the spindle continues to rotate. This happened while moving to my project and when cutting on the project. I thought it was just a random glitch and restarted the machine and all went well for awhile. When it happened a third time I was very frustrated with the need to restart and, as though just looking at the machine would help, I noticed that the spindle was actually moving very slowly…at 10 mm, barely noticeable…I had not noticed that before. I can recover from this event by pausing and then quitting the project and resaving gcode forward from the point of failure. The 4th time it stopped I was more attentive and again the velocity was 10 (mm).
I use the Nomad at a public library and I am the primary user and patron-caretaker for the CNC; I only had a few hours to experience these anomalies this past Saturday. A couple of factors that may impact my experience:
- I built the projects at home with CC 303 (MAC laptop) and then upgraded to CC 304 before milling (using my MAC laptop on the library Nomad). I really have enjoyed seeing the new improvements to CC and look forward to each new version.
- The library replaced the previous USB cable because it seemed to cause glitches…and it’s a public library so the ‘new cable’ is likely not new.
- I’ve experienced glitches with the Nomad over the 18 months I’ve used it and restarting Carbide Motion or my MAC (rare) has fixed what I would call typical events…but the shift to a fixed speed seems odd and the RPM change, coincident with CC 304.
- I am a newbie, self taught. I really don’t know more than what I experience.
I am going to go back to 303 (if I still have it in my downloads) and I have an old 290 build on a windows machine (both seemed more stable than 304). Still think you guys have built an awesome product…thought I’d share in case it helps pinpoint needed fixes. I am pending receipt of a power switch from Carbide Support; several variables going on, I know.
