Do I have to use the external Power Supply?

I have upgraded my stock K40 PSU with a Cloudray 50W PSU. Given I have a little more headroom, do I still have to use the external power supply?

Also, would the Laserboard be compatible with Cloudray’s 50W PSU?


You sure do need the external power supply. Given that most 50w LPSUs don’t have a 24v out option.

You’ll have to give us a hint as to what the LPSU is though if we’re to help you with the compatibility. Although nearly all are compatible.

This is the PSU:

Thank you for getting back to me so quickly. :slightly_smiling_face:

Yeah. That’s a decent LPSU and is compatible but it doesn’t have a 24V out and I wouldn’t want to use it for powering the controller and steppers etc even if it did.

Chris’ responses are spot on.

And although the LPSU’s look different on the outside, I think the connectors will be the same/ similar, so you should find this resource helpful:

Thank you, I really appreciate it!

Thanks for this. I’ll take a look now. :upside_down_face:

I just purchased the LaserBoard. Looking forward to installing it.

Thanks again for all your help.
