My Controller will not boot up. On 7/26/24 I ran 5 projects without any issues. Later that day I started another project. On the second pass on a guitar body the machine stopped, and the screen indicated that the controller was re-booting. I started the project over and about 25% into the first pass the machine stopped again, the controller was re-booting. At that point I shut the machine down for the day. Today 7/27/24 I started the machine it took a long time before it booted. I ran the first phase rough cut on the guitar side 1 with no issues. I properly shut the machine down and after lunch went to start it up again with no (zero) luck, the machine did not boot. I checked the power into the machine, and it has power to the CPU but it does not start and the CPU cooling fan does not run. I have the X-50 Journeyman 32x48. I need help ASAP ---

You may have a clogged up power switch. It’s been reported before. You can take it apart & blow out the sawdust (if you search here you should find the post). Or you could jump (bypass it using a wire on both sides) the switch to see if it powers up correctly and just replace the switch if jumping it works. Lots of them on Amazon. ---

Jim thanks for the thought. I have checked the power switch and it is working ok. Bill ---

Hey William, there have been reports with failing contacts on screw terminals / on their wire ferrules between the internal Meanwell Power Supply and the AVR Mainboard. ---

Some of the BB controllers have inline fuses: See here > [@Location of the Inline Fuse in the BB Controller (non Elite)](https://forum.onefinitycnc.com/t/location-of-the-inline-fuse-in-the-bb-controller-non-elite/7096): > > [Fuse specs: 6a 250v, 5mx20mm](https://amzn.to/3TSsNaa) Some older controllers do not contain an inline fuse ---

Also it’s summer so how hot is your shop? ---

Thank you for your information, it appears that the power supply unit is not functioning as necessary as the output Volts are less than 1V. It should be 36 Volts. I am ordering a new power unit today and hope this will resolve my issues. I have checked the one inline fuse, and it appears to be good. Yes, my shop is hot as heck, but I have good air movement with a large exhaust fan and floor fan. ---

Same issue with my 3yr old machine. And after the $577 replacement, the new controller’s power button will will not turn the controller off. These little issues with Onefinity increase my purchase ‘regret’ level. ---

That’s because it’s an on button and not an off button. Turning off should be done on the software fly out menu, just like a computer.

> [@GreenButterfly](#): > > the new controller’s power button will will not turn the controller off The controller is a computer. Just like any computer, you shouldn’t just power it off - using the software to power it down is the proper way to shut down so it can clean up open file pointers, etc. ---

Thanks Jim Good advice, and will follow. IF support pointed me to another $10 part that was needed to be added to the controller.
