Has this issue been resolved, if not - please contact us via https://ooznest.co.uk/help/ for further assistance

Has the issue recurred since? If not, maybe just a temporary power glitch from the utility company or similar. If it does keep recurring, the PSU may be damaged, if its in warranty - contact us via https://ooznest.co.uk/help/ otherwise if not under warranty anymore we offer replacement power supplies here https://ooznest.co.uk/product-category/self-build-solutions/workbee-cnc-machine/workbee-replacements/workbee-replacement-power-supplies/

With the information provided, I can't directly assist. The error message - that states "response too long, see console" was asking you to view the Console tab to see the actual, longer, in detail error message. Without that message we cannot know what the actual error was. Next time it happens, follow the error message's advice and click the CONSOLE tab - then view what the actual error was. It should be quite descriptive and tell you what went wrong - but if you need help understanding the message, feel free to reach out via https://ooznest.co.uk/help

1.8" tooling is a lot less rigid than 1/4" for example, so the tool itself is likely to deflect or even snap. If you can, try clearing the majority of the cut with larger, more rigid tooling - then use the 1/8" for cleanup of smaller features With the 1/8th" tool, we'd recommend a feed of around 600mm/min with no more than 1/16th" depth of cut. For slotting (where tool face is 100% engaged) try not to exceed 0.5-1mm depth of cut. That lowers the radial engagement forces and helps with tool deflection/breakage Remember: Increasing DOC [Depth of cut](axial) → linear force increase Increasing WOC [Width of cut] (radial) → exponential spike in load - slotting engages more of the tool, than say skim pass, or using a trochoidal type toolpath (Fusion 360) that limits engagement. The machine is capable of much more, the endmill choice is the main limitation here. Larger tooling will be more rigid and more effective
