The TIG idea might help on the bulges. I have a stud welder for pulling out dents and it has a "shrinker" attachment that pretty much does the same thing. Its been very inspriging to see how this CNC evolves...life has held up my build but I hope to incorporate many of your ideas!
The "Frankenstein" monitor arm reminds me of my shop worklight; The foot was the caster base from a gas-lift office chair. The column is the telescoping handle from a floor polisher, complete with quick-release cord storage. The light is an Anglepoise office lamp. All of the above were rescued from one dumpster, during an office refit where I worked. I later added a small table to lay tools on. My big mistake was lending it to my son... I won't be getting it back! 😡 I have since completed the Mark II version which also has a shop-vac with dust separator, and a 6 socket powerboard. Good to see your machine ready to rock again.
I would use a really thin cutoff wheel to make a radial cut right on the bulge and let the two side overlap a bit, then weld it. Your machine looks 100x more professional than most home build CNC
you could snip that warp, then weld it back. my hunch is that it will be a pain to get that perfectly flat and true unless you can un-stretch the material
Yeah there's not much hope for it besides applying heat and hammer. Regardless, I'm not taking it off again If I gotta take it off it's going to the bin! :D
Along the warped edge, it makes me want to just bolt a bar of stainless on top to flatten it down. Something like a piece of 1/4" bar bolted where are your screws secure the sheet metal. If you did it on all three sides of the frame you could flaten it out and still get a good seal with your cover. I don't remember what control software you are using. It doesn't look like Mach 3, unless you have a different screenset. It looks really nice.
Tried this a day or 2 ago with a piece 1/4" about 3ft long. Didn't seem to make much difference. The bulge that's got oxidation on it, I tried heating it up and squishing it with the 1/4" flatbar which seemed to help a bit. I think at this point I gotta get more destructive with probably the TIG torch and try flame straighten hacking it. :D
I tried linuxcnc in the beginning but it kicked my butt and I had to go to Mach3. I bought a touchscreen, but it's not compatible with XP, so now I'm trying to find a 32-bit Windows 7 install disk to get it all to work. Looking forward to seeing your maching make some chips!@@BryanHoward

Quick spot heat and quench with wet rag.

Hi Bryan good to see you got it back together. it would even better to see you making some chips again Cheers Bill
Absolutely!
Hi Bryan, I'm curious as to what control software you're using. It looks like a very clean interface that I saw on your screen?
CNC is run by LinuxCNC 2.9. The LinuxCNC interface GUI is called "Qt Dragon HD". It's Running in a realtime version of Debian 12.

Running linuxcnc 2.9 with qt dragon hd. version 2.9 more than anything is important to me because Python 2 must die already.

This thing is a monster. Did you weld the whole machine
Yeah, Most of it is covered in past videos too.
