I noticed that the rotary module immediately loses origin after pretty much anything it does. I can do the origin assist, then immediately do a carve, but if I have to cancel it and try to restart it, home, or simply “go to work origin” the rotary simply forgets where it is. Attempted to do a rough pass with an 1/8" bit, then used the built in bit assist to change to the straight groove v-bit to do a finish pass. Did a run boundary aaaand… the rotary module just spun. Checking the control the rotary says it’s at some thousands/millions of degrees. If I try to set B manually, it then forgets X/Y and I have to break down and just do the origin assist again with the new bit. However; this poses issue as now there’s absolutely no way to be exactly where I was in relative to my previous carve.
Another question that comes up is this; if the rotary module doesn’t actually have a ‘home’ position (via limit switch or other) then how would say, power panic work? This is a very serious limitation for those who don’t want to spend days letting the v groove carve EVERYTHING, it’s senseless, slow, and excessive wear on a bit they only give you one of.
Anyone else experience this? Is it a fluke of mine or is it by design?
Edit: with further testing, it seems the rotary module is just that far out in degrees for whatever reason. I did a test where I loaded a bit, set the origin, and made a top mark to compare. Then changed the bit, using bit assistant. Afterwards I homed the machine, and the rotary module said it was over -10300 degrees. So I decided to just let it go, tapped go to work origin, B said 0 degrees and began spinning… And spinning… Somewhere between 5-10 minutes before it stopped at the correct place.
Tapped home again, it rotated back about 120 degrees, back up to -10k… Go to work origin, same thing. It had to rotate back those 10k degrees despite only rotating partially during homing. Though it seemed to return to the proper place, just takes awhile. I’ll do more testing.
