A Tale of Two Days, Terminal Warfare, and Why You Should Never Touch the Wi-Fi Settings (Plus an 8x4 Setup Guide)
Hi everyone,
I’ve just emerged from a grueling, two-day technical wrestling match with my Maslow 4.1 following the latest firmware update. Now that the sawdust has settled and I’ve successfully achieved a glorious 0.37 calibration fitness score, I wanted to share a few hard-learned lessons, a massive warning for new users, and a feature request for the developers.
1. THE ULTIMATE WARNING: Step Away from the Wi-Fi Mode Settings!
If you take away nothing else from this post, let it be this: Do not change your Wi-Fi Mode to “AP Only” in the settings. During a bit of standard troubleshooting, I swapped the mode. The firmware instantly trapped itself in a catastrophic boot loop, completely dropping the Maslow access point from the face of the earth. The UI was gone. My laptop couldn’t see it. The machine was booting up physically (fans spinning, standard startup sounds), but the radio was completely dead.
To fix it, we had to go full-on “computer hacker” mode in Linux. It required installing native serial monitors (tio), tapping into the hardware pins via USB, and fighting a firmware interface that aggressively rejected shorthand commands with cryptic error:3 codes. We eventually had to blind-type the exact full path syntax: $WiFi/Mode=STA>AP followed by $System/Control=Restart just to force the access point to broadcast again. Save yourself the terminal warfare—leave the Wi-Fi settings alone!
2. The Firmware Update: A Tale of Missing “Out-of-Square” Tolerance
Before the most recent firmware update, my Maslow 4.1 calibrated quite happily on a massive, out-of-square 12\text{ ft} \times 7\text{ ft} frame bolted directly to my workshop wall. It was brilliant, versatile, and highly forgiving.
However, the new firmware update appears to be wholly intolerant of out-of-square anchor points. It completely threw its toys out of the pram trying to run the math on my old rig. This strict intolerance ultimately forced me to abandon my large wall setup entirely and opt for a much smaller, dedicated 8\text{ ft} \times 4\text{ ft} benchtop frame. While it works beautifully now, losing that massive cutting area is a real shame and feels like a step backward for user-friendliness.
3. A Suggestion for the Devs: Bring Back the Math Flexibility
If the previous firmware could happily calculate and compensate for a slightly skewed or out-of-square anchor setup, it must be mathematically possible here.
My suggestion for a software revision: The dimensions calculating software could be updated to implement a Skew Compensation Factor or a secondary calculation pass. If the initial rigid geometric matrix fails due to out-of-square anchors, the software should fall back to a triangulation algorithm that treats the four anchor points as an irregular quadrilateral rather than a perfect rectangle. By allowing the software to calculate unique vector offsets for each corner based on the actual measured distances (rather than forcing them to conform to a strict orthogonal grid), the Maslow 4.1 would become infinitely more versatile for real-world workshops where walls and frames are rarely perfectly square.
Quick Guide: Setting up a Fast 8x4 Benchtop Rig (UK Supplies)
For those trapped by the new firmware constraints who need to set up a rigid, compliant 1800\text{ mm} \times 600\text{ mm} cutting grid on a standard 8\text{ ft} \times 4\text{ ft} sheet framework, here is the quick-and-dirty setup guide to avoid the pitfalls I hit:
-
The Frame: Build your base using standard C16/C24 structural timber (47\text{ mm} \times 100\text{ mm}) to ensure absolute rigidity. Ensure your sheet material sits completely flat.
-
The Software Safety Trap: When you first boot up after a reset, the UI might throw a terrifying “Low Z Position” warning, locking out your Z-axis because it thinks the bit is buried in the floor.
-
Dismiss the warning.
-
Click Define Z Home on the right panel to snap the readout back to a safe 0.00mm.
-
Head to the Settings tab and temporarily toggle Soft Limits to OFF. This gives you full manual control to drop the axis to the bottom of the frame for anchor setup without the software blocking you.
-
-
Running the Grid: Use a standard 3x3 calibration grid. Be prepared for the console log to shout a few yellow warnings at you under the hood (like Retraction force exceeded limit). Don’t panic—during calibration, the sled is pulled into extreme corners where belt tension naturally spikes. Clear the logs and trust the final score.
-
Locking it In: Once you get a tight fitness score (anything under 1.0 is great, my 8x4 hit an incredible 0.37!), remember to immediately scroll down and hit Save Configuration so it writes permanently to your maslow.yaml file. Turn your Soft Limits back ON before cutting.
-
Mind Your G-Code Origin: If your CAM software (Easel, Carveco, etc.) is set to center origin, physically jog your sled to the dead center of your plywood sheet and hit Zero X and Zero Y in the Maslow UI. Your on-screen preview crosshairs will snap perfectly to the center of your design.
-
The “Clunk” Fix: If your router sounds rhythmic and clunky when changing directions, your clamp is slightly loose. If it bottoms out before fully gripping the router barrel, wrap a thin shim cut from an aluminum drinks can around the router body before tightening the clamp. It stops the rotation instantly and smooths out the cut.
A massive thank you to the community members who helped keep me sane over the last 48 hours. Hopefully, this saves someone else a massive headache!
Cheers,
