I’ve had my SV08 Max for a while, and I keep running into inconsistent first layer issues specifically when printing parts that use most of the bed area. ### Problem I didn’t get a chance to grab photos of the failed first layer, but the behavior is consistent: - One part/area of the bed has excellent first-layer “squish” (fully opaque lines, cannot see the bed through it). - On the **right side of the bed** , the first layer becomes **see-through** and I can clearly see the bed between lines / gaps. This makes me think it’s a **bed leveling / gantry leveling / mesh** issue rather than slicer settings. ### What I’m printing with - **Filament:** SUNLU PETG HiSpeed (Black) - **Bed temp:** 75C - **Nozzle:** (see attached settings) - **Slicer & profile:** (see screenshots) **Attached screenshots:** 1. Bed mesh heatmap / visualization (after leveling) ### What I’ve tried To remove thermal drift as a variable, I did a long heat soak: - **Bed at 75C + nozzle at 150C for ~30 minutes** Then ran: - **QGL** - **BED\_MESH\_LEVEL** Even after that, my **mesh heatmap still looks very “off” / uneven** , and it matches what I’m seeing in the first layer (good in one area, too high or too low on the right). ### Z-offset / filament gcode To make sure this isn’t a Z-offset inconsistency between starts, I have this in filament gcode: `; Filament gcode` `SET_GCODE_OFFSET Z=-0.07 MOVE=0` What’s weird is I can dial in a Z-offset that looks perfect on one side, but it will still be under-squished and gappy on the right side. ### Questions 1. What are the most common causes of a **right-side first layer under-squish** on the SV08 Max even after heat soak + QGL + mesh? 2. Does this sound more like: 3. Anything specific I should check or run (commands / tests) to isolate whether it’s **probe accuracy vs mechanical vs mesh application**? If there are any recommended diagnostic prints or commands, I can run them and report back. ---

Try adjusting your mesh area to end 10-15mm further from the edge. ---

I didn’t even know you could do that. Is that a parameter you can adjust in the console when doing a “bed\_mesh\_level”? ---

See the [bed\_mesh] section of printer.cfg ```auto [bed_mesh] speed: 400 horizontal_move_z: 1.5 algorithm: bicubic mesh_min: 13,15 mesh_max: 476,490 probe_count: 60,60 fade_start: 0 fade_end: 10 scan_overshoot: 4 ``` The parameters mesh\_min and mesh\_max are X,Y coordinates for the rectangle that gets measures. As far as I can tell Sovol uses stock Klipper [bed\_mesh] settings. > **[\[bed\_mesh\] - Configuration reference - Klipper documentation](https://www.klipper3d.org/Config_Reference.html?h=overshoot#bed_mesh)** > > This document is a reference for options available in the Klipper config file. ---

I changed the x, y to 486, 490 and I got these errors when running bed\_mesh\_calibrate. !! Move out of range: 505.390 15.750 1.500 [0.000] !! Move out of range: 505.390 15.750 1.500 [0.000] ---

You need to decrease the size of the mesh. Try > [@cardoc](#): > > ```auto > mesh_min: 13,15 > mesh_max: 461,490 #Was 476,460 > > ``` Be sure you are in the [bed\_mesh] section. ---

Maybe just me, but I had similar experiences. And then I had bed heating issues so I took the heater out and inspected it. all of the screws holding the heating element to the bed plate magnet were slightly loose. After warming the plate and re-torquing all of the fasteners from the center out, I was able to eliminate the bed heating issues and the un-even bed mesh. May be worth a look on your unit. ---

My bed mesh looks EXACTLY like your photo and I have a mesh range of 0.5. Did you find the solution for this problem? Someone told me the extruder might be the problem but I only printed petg and its under 500h ---

@mooseprinter did you ever find a solution for this? i am going through the exact same problem now.
