3D Printing Forum

Using a Makerfarm Pegasus 8 which in turn is Using Marlin Firmware 1.x, trying to improve my accuracy and was wondering if there is a way to tweak my setting for the manual leveling process.



When performing a manual bed level, when i turn the knob the x carriage moves up or down at .5mm increments (I think) is there anyway i can lower the number to .25mm or .1mm.



Perhaps I'm being anal, but I like to be as close to possible when running the process.

Thanks

Are you looking for
#define MBL_Z_STEP 0.025 // Step size while manually probing Z axis.

Perhaps, is this line already in the Marlin Config.h or am I adding it? Conversely is there a way to do it via Pronterface and gcode commands?

I found it in all versions of marlin 1.1.x that I have programmed for My 3D Printers.

I do not know of a way maybe, someone else will know.

If its of any use I redesigned an Auto Bed Leveling Sensor Mount. Unlike the 3 part assembly thats on Thingiverse, my one is only a two part and fits the linear bearing housing perfectly.

If I get the time I guess I should upload the files onto Thingiverse as its easy to fit and adjust.

You can also post a picture here.

The print beds on 3D printers aren’t always perfectly flat. Sometimes you can get lucky and get a pefectly flat surface to print on, but considering the materials the bed is made out of and the constantJT whatsapp heat cycling, it’s more likely that you’ll have to deal with at least some warping.

Mesh Bed Leveling
There are few options for compensating for a warped bed, but I chose to use Mesh Bed Leveling because it didn’t require any extra hardware or tools.

This does require building a custom configuration for Marlin.

At a minimum, enable mesh bed leveling in Configuration.h:

SNo4 Proximity Sensor Mount here

I have designed a mount for Omron TL-W3MC2 attached, was looking here could not find my post so re-posted link

Specifically, you have to make sure the frame is rigid, especially the portion that supports the Y axis guide rails, and use a flat plate.

I will suggest you adjust the probe points, select the bed leveling method, and give access to the configuration. I think this will work enough.

When manually leveling the bed in Marlin, fine-tuning the leveling increment can make a significant difference. Start by adjusting the screws to get the bed as flat as possible. Then, use the leveling increment feature to make small, precise adjustments. This allows you to dial in the perfect level without overcompensating. Remember to check all corners and the center, ensuring even spacing between the nozzle and the bed. youtube vanced

The manual bed leveling feature in Marlin firmware enables the surface of the print bed to be adjusted. By modifying the step size for every manual leveling adjustment, the "Leveling Increment" comment allows for more accurate height adjustments to be made throughout the bed leveling procedure for the best print quality.
