Five minutes in, I switched to 1080. Your 50K cycles would be a half for Brymen and what I am doing but still, what is up with this meter? There is no way I would have expected to see these results after sending you those original pictures. Impressive indeed.
I expected worse too, but that's what we got.
I don't know what serial number I sent you, but it would have been around a similar date, so likely exactly the same switch and contacts.
If these were the production parts, I would like to try and understand why such a dramatic difference. I wouldn't have guessed it had more than a thousand cycles on it but for all I know, UEI may have cycle tested it. Looking back over the pictures, it appears the contacts are what was wearing. Even looking at the last few that they sent, it looks like something was still going on. Strange.
Looking at the video and the large gap in the fingers that rotate the knob, are you sure you are getting the full stroke of the switch? It looks like it may only rotate 90 degrees. Still even it that was the case, I would have still expected that area to have a fair amount of wear.
Just scratching my head.
I’ll add to the head scratching. Or let’s just say thinking out loud.
I agree with Joes counting as this is only a half cycles since a user will turn on, then off and that’s a full cycle. Just like they charging cycles on a battery, charge and discharge for a full cycle.
My questions thinking out loud would be around the way the PLA adapter is mounted to the stepper motor. Seems to me and knowing PLA (it looks like PLA) the part will wear some and if a set screw was used the adapter on the motor will start to slip. I’m not a big fan of PLA for mechanical use from personal experience when I first started doing 3D printing.
Maybe something a little stronger on the adapter with something that also has a little flex like a nylon mix filament. The nylon will allow a little flex without breaking the part, and you can over turn the switch just a little past the off positions. My thinking is most people always turn past the off point, they only let go of the switch because the switch stopped them. I’m not talking crazy over shoot on the switch with massive torque, just a little to replicate real human usage. If you set the controller to over shoot with a PLA part even if it’s made with 100% fill, it will start to stress crack, break, or give away on the tolerances of the whole for the set screw and slip.
But I guess that’s why I’m wondering how the part is held into the stepper motor?
It’s a nice rig, but just might benefit from a few little tweaks?
