Not sure if it's hardware or software

Hi everybody,

So I just upgraded my hot end to the V3b with the core for the 19V machines. At the same time I upgraded to the new version of Simplify. For a second I was able to successfully extrude and control the machine, but now Simplify seems to freeze after a few seconds, or immediately following two commands sent via the control panel. Anyone else ever run into this?

The only time I've gotten a lock up on S3D has been on my laptop. But its either because the video card can't handle it or not enough memory. Locks up when I hit the "Prepare to Print" button. Sorry but that's all I can contribute, not likely to be your issue.

i have never had it lock up either. only appear to lock up during slicing if my support grid accidentally get dropped to some crazy low level. it takes forever to do the slice. other than that though i have never had an issue. check your normal things like the baud rate is set correctly, reset the rambo board then try to reconnect.

I upgraded to the correct firmware and then reinstalled simplify. That did the job.
