This mill is sold under many names like Jet 350020, Grizzly G0705, rong fu, central machinery, etc...The closed loop board was taken off a maxNC and uses high quality U made pacific scientific steppers. The spindle is controlled by a solid state relay. The conversion was done about 15-20 years ago. Interesting is mach3 these has a configuration for this and I got it working. Look at the similarities below. https://www.amazon.com/350018-230-Volt-Milling-Drilling-Machine/dp/B000051WSL?crid=3SC7K5D6JTO94&keywords=jet+round+column+mill&qid=1655317125&sprefix=jet+round+column+mill%2Caps%2C120&sr=8-27&linkCode=ll1&tag=fintechcomm0f-20&linkId=bbaa13833c393aa60b0864c4fd804881&language=en_US&ref_=as_li_ss_tl

I scored this on offer up for $35. I have about $65 into it. I was happy to get a unique American made craftsman. This think is heavy duty cast iron. This thing cut through steel like butter.

I finally had to pull the plug on my Crypto mining operation. I mined for years profitably until recently. In CA there is a multi tiered power. The more you use the more expensive it gets. In other states the more you use the rates go down. The only thing that thrives here is homelessness and crime. Just kidding, I need the extra power to run my new CNC stuff.

I finally got my VFD hooked up to my 1966 Hitachi lathe motor. The bearings sounded like they were shot. I was surprised I was able to find some replacement bearing for $10 each.

If you don't want to watch video and troubleshooting process then the problem was a corroded AC pressure switch connector. My wife's Cadillac AC became intermittent and stopped blowing cool air at idle. The problem was the AC condenser fan was not turning on and created a high pressure situation. The high pressure situation caused the system to open the emergency pressure relief valve. This in turn created a low refrigerant issue. I traced all the wires back to the source and tested fuses and relays. I was able to find the GM dealer software on the internet and was able to verify the fans were indeed working. The ECU was not being commanded to turn on by the AC system. I traced it back to the AC pressure switch. Once I found the switch, located under the front grill I found the corraded connector.

For about a year I've been dealing with random reboots on my RX 5700 XT rig. Non of my wires were burnt or hot. When I changed over my GPU's to a different rig and power supply it became very apparent that the RX 5700 XT draws allot more power from the PCI riser then my Nvidia cards. I had burned wires and GPU's going offline within a week. I directly soldered 6 pin connectors directly to the power supply board.

I feel like the XT bios is just a way to scam more money out of existing hardware. There is no difference in the hardware. The XT bios allows for more overclocking and higher power consumption. I've been wanting to do this experiment for awhile. I wanted to know what would happen if I put a non XT bios on a XT GPU. I seemed to pickup a few megahash and save about 15-20 watts of power.

I'm always lookout for local deals on GPU's. The got this from a guy that said it would crash in windows idling longer then 5 minutes. I thought it was weird because GPU's usually overheat and crash during full load. I took the risk for $150. I figured I might have to replace the thermal pads or repaste the heatsink.
