Power Supply for Carver King 1

[sean1981]

In search of a power supply cord for my machine.  

I believe the original model was a YU2405 and the pin size was 5mmx2.5mm. 

Does anyone know if the universal power adaptors at Best buy could work? Or if you've purchased a replacement, where did you buy it? 

I was hoping to be able to get it today from a store. 

Thanks in advance.

sean1981, welcome. 

Your question is somewhat vague.  You mention "power cord" but then refer to "power adaptors" and a model YU2405 with jack.  The 120VAC power cord is detachable from the power adapter/brick you reference, which is a power supply, thus the confusion.  But I'm going to assume you are looking for the entire power adapter unit.

The model YU2405 is a 24VDC @ 5Amp unit.  Best to contact MillRight Support <[e-mail]> for a replacement, they are usually very reasonable on replacement parts. Alternatively, here is a compatible (YU2405) one I found on amazon www.amazon.com/SHNITPWR-100V-240V-Converter-Transformer-5-5x2-5mm/dp/B07PWZQ4MB

I'm not in the shop right now so I can't check the V/A of my CK1 power brick, of course you want to be sure of the specs before you replace it if MillRight is not the supplier. I'll check my unit later today and if it's different I'll post an update here.

As I recall, just FYI, this power supply powers the CK1 motors and drivers, where as your computer USB 5VDC powers the Arduino grbl controller.  So if UGS is not talking to grbl, its not likely a 24V power supply problem, it's likely a USB connection problem, something with USB port on your computer, or Arduino board has failed.  If UGS talks to grbl just fine and grbl behaves as if CK1 is operating normal but no axes move, then your likely on the right diag path; but measure the output of the original supply if you have a volt meter and resistive load available. If not, $20 is worth the easy swap of a new power supply. Usually these switching power bricks have internal short circuit and overload protection, so if they work once they work forever (until you find one that doesn't of course

Good luck with it.
