I sort of "split the difference" and got this one for $250 - https://a.co/d/gJoQYTo (Beelink EQi12-/1220P/16G/500G with Windows 11). Single core Passmark is 3400 or so, so there's some headroom available, and it outperforms the 1235 on the more ...

Re: DOA!!! Not a Happy Bunny < bricked firmware?>

I installed with Windows 11 and everything worked fine. I suspect there's more going on somewhere. Glad you got it resolved!

Re: DOA!!! Not a Happy Bunny

Does the Beagle Bone have a heartbeat if removed from the Centroid board and powered via the mini USB?

Re: Acorn or C86ACCP

It sure looks like the left side of the C86ACCP may not be seated all the way on the Acorn board. Any chance it's something as simple as that?

Re: Z-Axis Brake with Clearpath Hard Stop Homing

Are you using the program in Centroid's tech bulletin to do hard stop homing? It looks like homing should only start after the first enable signal from the controller after everything is powered up. Centroid's preferred configuration can be found here: https://www.centroidcnc.com/dealersupport/tech ...

Re: Z-Axis Brake with Clearpath Hard Stop Homing

The brake should normally be released any time the axis is powered, i.e., as soon as the controller is powered on and a control signal is sent to the motors, applied again in an E-stop condition, and released again upon subsequent axis movement. The axis doesn't have to move for the brake to be ...

Re: WMPG-6 High CPU Resources on MPGClient.exe

Looks like the WMPG-6 is a WixHC unit that shows up as a generic HID-compliant vendor-defined device in Windows. It shouldn't need its own separate drivers, or consume a lot of CPU absent a whole ton of activity. I wonder if you have noise/interference at 433MHz? Or maybe batteries in the MPG are ...

Re: WMPG-6 High CPU Resources on MPGClient.exe

N150 PassMark is 1911, which exceeds the required 1500 and is pretty common in really low end NUC-type devices. If it does end up a hardware problem, this NUC has dual Ethernet, Windows 11 preinstalled, and an i3-1220P with a PassMark of 3300 for $250: https://a.co/d/9IsRJXu

Re: Centroid CNC Software Licensing Upgrade Announcement


I like the new pricing option, if new functions are something worth for your work pay for them, if not enjoy bugfixes for free.

That's not a bad way to look at it, as long as big fixes don't get stuck in higher level releases only (e.g., a bug introduced in 5.2 should be fixed in a ...

Re: Choosing the correct VFD

Yaskawa, Hitachi, and Delta are all good brands, while some "store brands" like Automation Direct's DuraPulse have also been good. Check out, for example:
