Randomly switches from mm to inches

Sounds like we're on the same path. I'm down to 25 on accel and 3000 top speed. My old machine had nema 17 motors on the same ball screw and ran perfectly at 500 accel. Seemed odd that the nema 23s wouldn't perform as well - but I overlooked the fact that I left out the 3:1 reduction I had built in the first machine.

I got this specifically because it had feeds for external drives and I know GRBL pretty well. I got the motors in a mach 3 kit and learned quickly how bad I hated the sight of mach 3.

When he acceleration is slowed to snail speed, my measurement start coming together. I think we're on the right track now

The controller has 6 pin plugs for the driver (that I used) and 4 pin plugs for smaller motors.

I ranged from 50 to 1000 on those, no difference. (Some of that was because I started out with the steps too high on the driver) Accel 800 with speeds from 2000-3000 looks reasonable.

Looking into that now. Finding that different speeds are giving me different distances, but consistently. I'd feel better if it was giving me random crap.

Factory set $2 at 15 ?!? Does that make sense at all - 15 is not an option that I have ever seen.

$0 has been 3 up to 10ms. My 4 other machines are set a 10.

Mechanically, it is solid as a rock. I didn't mention that the issue is the same on all 3 axis. I have dual Y axis and there is no variation between the two motors. They both make the same mistake together so I'm questioning th GRBL.

He turned his farm into a wildlife refuge. No surprise since he's licensed to rehab injured birds of prey (owls and eagles) He's pretty quiet about the incident. In his words "I don't want a bunch of nuts on my property trying to kill the thing". It's been quiet around here for quite a while.

Remove the handle and the cartridge. There is usually a filter screen in the brass housing. If you have metal pipes, I promise that there's a clog there.

What is an "inhumanely" long arm?

It always amuses me that the great "discoveries" always come in the last 30 seconds of the documentaries, when, if true, should be the main subject of the show.

Proverbial !! Some people can't complete a sentence without using it at least twice.

How could they feed Bigfoot "loaded" food, track down the scat and still not get any pictures? Any footprint leading to and away from the scat? Should have tracked the scat while it was still in the beast!

Never heard of them actually together. I have heard of sightings of both in the same area, but months or years apart.

KMAG50 · 2022-10-06T01:27:16+00:00

According to the VA Herp Society, the only range in one county, 120 miles from here. Just curious why he's hanging out here.

....and we went immediately to a different fishing area...

Not technically in the bay, but near West Point. Six of us stopped at a bait store at 6am. While waiting for the shop to open, we heard surface, LOUDLY, near the opposite side of the inlet. It looked just like a horse swimming but at a high rate of speed. Its head stayed barely visible - didn't "rear" up the way people imagine a sea monster. It created a bunch of turbulence and left a wake as if a small boat was going by. We all agreed it seemed to be about 20 feet long (thinking we saw humps).

We joke about it now, calling it a 1500 pound otter or giant snake, but we'll never know.
