Hi Elliot, we're sorry for the delay. This kind of issue is often related to the Y-axis lead screw or coupling on the near side. If the spindle feels loose, it’s worth checking that the lead screw is properly secured in the flexible coupling and that the bearings and mounting points are tightened correctly. We’d also recommend ensuring both Y-axis motors are wired and configured correctly, as they should move in sync rather than one pulling the other. If you are still having this issue, please contact our technical support team via https://ooznest.co.uk/help/. Hope that helps!

Hi Lloyd, Sorry to hear about the issues you are having. If you go to Control > Console you can see the full error. We have made a guide on solving the Outside Machine Limits error here: Outside Machine Limits Troubleshooting Give that a read and let me know if it does not solve your issue. (Please note if you have an M3 error, this error is not the reason why your job is not running. The M3 error is just trying to set the speed on a spindle. But with the WorkBee we use manual speed control router heads.) If the issue continues, reach out to us directly so we can help you further: https://ooznest.co.uk/help/

Hi Ezra, Sorry for the delay in our reply. If your G-code file is loading successfully but no toolpath is visible in the preview, this is usually related to how the file is being displayed rather than an issue with homing or probe calibration. We recommend checking that the correct visualisation settings are enabled in the G-code viewer, such as ensuring the preview mode is active and that the view is zoomed appropriately to fit the workspace. It’s also worth confirming that the file you’re using is one of the provided project files from our website and hasn’t been modified, as these are set up to display correctly with the recommended software. If the issue continues, reach out to us directly at https://ooznest.co.uk/help/

Hi Pete, It sounds like the machine may not have the correct size set in the firmware. Please check this step in our guide: Step 3 – Set Machine Size — it’s easy to miss during setup. If you've already done that and the issue continues, feel free to reach out to us directly at ooznest.co.uk/help and we’ll be happy to assist!

Hi Ralph, Mounting 2 vertical 20x60 extrusions onto 20x20 horizontals with free-moving gantry plates is absolutely doable. To help you choose the right gantry carriages, we’d need a bit more info—like where you want the carriages positioned and how they’ll be used—so we can recommend the best option. Please send us a rough sketch of your project at help@ooznest.co.uk As for locking them in place, you can use sliding extrusion nuts in the slot with M5 screws and aluminum spacers to build a simple stop. While we don’t currently stock hand-operated knobs, you might find “M5 knobs” with threaded studs from local or online hardware suppliers, which would replace the M5 screws for easy manual adjustment. I hope this helps and looking forward to hearing from you!

Hi Phil, Glad to hear it's now sorted. Feel free to reach us if you need help with anything else!

Hi Ted! Yes, you need to factor in post-processing. The Duet Controller uses RepRapFirmware, which requires G-code with full modal commands on every line (e.g., G1 X... Y... Z...). FreeCAD may not have a built-in Duet-compatible post processor, so check the FreeCAD forums or consider using another CAM tool to generate compatible G-code. Learn more here: http://docs.duet3d.com/User_manual/Machi... I hope this helps but let me know if you have additional questions.

Hi Phil, Thanks for reaching out. Based on your description, it seems the Z-axis limit switch might not be functioning correctly. Here are some steps to help you troubleshoot: (1) Check Limit Switch Status: In WorkBee Web Control, navigate to Settings > Machine Specific > Sensors. Manually press and hold the Z-axis limit switch. The status should change to 'Triggered'. If it doesn't, the switch may be faulty. (2) Inspect for Debris: Sometimes, dust or debris can prevent the switch from operating correctly. Clean the switch thoroughly and test it again. (3) Verify Wiring: Ensure the limit switch wiring is correctly connected and not damaged. Refer to the wiring diagrams in the assembly manual for guidance. (4) Test the Switch: If after cleaning and checking the wiring the switch still doesn't respond, it might need to be replaced. If you've gone through these steps and the issue persists, please contact our technical support team at https://ooznest.co.uk/help/ so we can better assist you.

Hi Josh! It sounds like your machine is out of square. Even if the X and Y gantries seem perpendicular, the overall frame or gantry may still be skewed. Double-check that the frame is square by measuring diagonals, and ensure the gantry is equally spaced on both sides when moved front to back. Also check for any mechanical play, calibrate your steps/mm, and make sure your spindle is trammed correctly. These are the most common causes of inaccurate or out-of-square cuts. If you need further help, please reach out to us at https://ooznest.co.uk/help/ so we can better assist you.

Hi Robert, Your workflow is solid! Roughing with a flat endmill and finishing with a ball-end is standard. If you want more detail, consider adding extra finishing passes with gradually smaller ball-end bits. Avoid v-bits for finishing as they’re meant for engraving. Instead, look into tapered ball-end mills, they’re stronger and great for fine detail without breaking easily. If you're finding smaller bits are breaking, consider adding an intermediate finishing pass with a slightly larger ball-end bit (e.g., 4mm). That way, the final small bit only needs to handle the fine detail, not heavier cleanup, which can cause breakage. Hope that helps refine your process! Let us know if you anything else.
