This is a Miller MRV2 6 axis welding arm, and i'm having a heck of a time finding any sort of documentation or manuals to start figuring out how to get it working again.

That's an ambitious project! I hope you post your progress... As far as documentation goes, you need to contact Miller. They will literally hand the book over to you. They're awesome for stuff like that. Skip the google searching, go right to the source and ask the horse.

Awesome, thanks for that info. I'm definitely going to give them a call and see what i can get. I'm much more experienced with chinese DC steppers, so these AC servos are a bit new to me. Absolutely worst case, I'll strip all the AC out of it and replace with DC motors. I want to get as much info as i can before i start making changes though.

This is a clean copy: https://www.militarynewbie.com/wp-c...-Machinery-Repairmen-NAVEDTRA-14161_14162.pdf

Didn't think to look.
A good, properly bookmarked, copy is in the Downloads - Military Manuals
Chapter 5 Offhand Grinding of Tools and Selection of Carbide Tooling and other chapters are also uploaded as single files
Found them when I was looking the proper place to upload a copy.

Check @macardoso he’s got an extensive thread on here about his robot arm.

As well as the purpose of the arm, I'm curious as all get out what it's lifting capability is. Manual use with joy stick

Well I bought what I through was an er32 collet set for my mill. WTF is OZ25?

To top off my pain and suffering on this, the draw bar threads are incorrect. NMTB30 is 1/2"-13 but this stupid set is M12*1.75

I'm going back to the seller, they did clearly mark it as NMTB30, so this one isn't my mistake. Maybe I can get somewhere with eBay...

A new mouse for 3D modeling use

I’ve been looking for a wired mouse that fits my claw grip, preferably one with an interchangeable cable and no logos or RGB lights. I went to a local computer store where they had 50+ mouses on display and this one felt so good in my hand, that I had to buy it:




It’s the HyperX (Kingston Technology Corporation) Pulsefire Haste 2.

While there is nothing I can do about the ugly logos or the fixed USB cable, at least the RGB lights can be disabled using OpenRGB

I also got a heavenly steamed pork neck bánh mì, but that’s a completely different story

…at least the RGB lights can be disabled using OpenRGB

Well, they could be disabled if only my machine supported a newer version of glibc.

To solve this issue, I tried to perform an in-place upgrade from RHEL 8 to RHEL 9 using Leapp, but it turns out LUKS encrypted partitions inhibit me from doing so. I guess I’m stuck with the RGB lights then.

I remember someone making a claim that 2024 was (finally) the year of Linux desktop
