Hyperfine bed leveling?  

Google Spreadsheet

So while printing squares and writing down values of Z live and measuring with a micrometer.. blabla.. it becomes a lot of numbers to keep track of on a sheet of paper. So i started doing it in a spreadsheet.. Then while printing i started setting up that spreadsheet to make things easier..

Maybe someone else would like it as well ? 🙂

Not a lot of fancy things going on:
1) It highlights the top 3 results in each "section" (Green, yellow, red) -- Because i lost track after a while myself..
2) Displays the best numbers on a grid similar to your print bed viewed from above
3) Auto calculates the offsets based on your numbers. (I think its the right direction?)

HFM-firmware for MK2.5 ?

I searched the github and I didn't find a firmware for the MK2.5 upgrade 🙁

Hi, i will try to get it done this week. It will be 3.1.3-HP with Hyperfine Bed leveling and PINDAv2 fix.

Re: Hyperfine bed leveling?

Updated the source code to fix the bug, checkout the Github for more information.

Can you post on Github what you have tried to reactivate Dcodes?

Now you're asking a lot of my Github skills, hehe, i know where to click downloads but thats about it, I tried the following:


// Configuration.h:14
define FW_DEV_VERSION <x>

// Uncommented this line ^


https://github.com/3d-gussner/Prusa-Firmware/compare/v3.1.3-HP...MK3-private_build Is this the change you are talking about? Would you advise to download and run this firmware instead of the Pre-release hex?

Hi,

fixed the hex file, so if you want give it a try checkout this: https://github.com/3d-gussner/Prusa-Firmware/releases/tag/MK3-v3.1.3-HP

Re: Hyperfine bed leveling?

I am also waiting for 2.5 hyperfine firmware .

I updated the changes from private and built this source code the same day as my post. I have not experienced any issues as of yet, but I have not been doing longer prints using this firmware. Been busy most days, and i'm still working on levelling out my bed.

Re: Hyperfine bed leveling?

Tipping my hat at those who worked on this Hyperfine Bed Leveling. One thing I noticed is that my bed level correction numbers are no longer as extreme as they were with the original method. It seems that for some reason, the mesh bed leveling is doing a better job on its own now with hyperfine. I had already modified my firmware to allow +/- 99 on the LCD and I was maxed out in two areas and not able to get the 5 points perfect at a .2mm layer height. I now have 9 points perfect at .15mm layer height! Awesome job people, and thank you!

Glad to hear that it works for you. May I ask which firmware did you use, MK2/s,MK2/sMMU,MK2.5 or MK3?

Added this GCode to the firmware as well (M666) https://github.com/prusa3d/Prusa-Firmware/pull/542
Made it easier to start at a consistent pinda temperature, might be worth looking into.

Thanks for the update, i saw it also being pulled but also bit modified.

Re: Hyperfine bed leveling?

Have any one try to do temp. Calibration with this firmware?

Re: Hyperfine bed leveling?

Add this code to Marlin_main.cpp:
SERIAL_ECHOLNPGM("Bed leveling correction finished");
mbl.upsample_3x3();
SERIAL_ECHOLNPGM("Upsample finished");
// ----New Code----------------------
for (uint8_t i = 'j'; i < 'x'; i++)
{
float correction = 0;
if(code_seen(i))
{
correction = (float)code_value();
int intCode = (int)correction;

// Make sure both coordinates are 0-6 and the offset isn't larger
// than 0.1mm
if(xval < 7 && yval < 7 && fabs(offset) < 0.1)
mbl.z_values[yval][xval] += offset;
else
{
SERIAL_ECHOPGM("Invalid coordinates or offset: ");
SERIAL_ECHOLN(correction);
}
}
}
// ----End New Code------------------
mbl.active = 1; //activate mesh bed leveling
SERIAL_ECHOLNPGM("Mesh bed leveling activated");
go_home_with_z_lift();

I am new to 3D printing and firmware mod. Where do you put this code/ in the beginning or at the very end?

SERIAL_ECHOLNPGM("Mesh bed leveling activated");
go_home_with_z_lift();

It says where to do that:

in file: 'Add this code to Marlin_main.cpp:'

find there: 'SERIAL_ECHOLNPGM("Bed leveling correction finished");
mbl.upsample_3x3();
SERIAL_ECHOLNPGM("Upsample finished");'

Add after that : '// ----New Code----------------------' and following until '// ----End New Code------------------'

Your change should then be before 'mbl.active = 1; //activate mesh bed leveling
SERIAL_ECHOLNPGM("Mesh bed leveling activated");
go_home_with_z_lift();'

Re: Hyperfine bed leveling?

Any chance we can see the original post updated with a full update as to where we're at with everything?

I'll work through reading all 34 pages tonight, but an update in the original will be helpful for other users who are just coming across this thread.

For example, G80,G81, Are those custom codes?
Which set of firmware is the most up to date re: hyperfine bed leveling?
MK3 3.2.0-rc1?

Hopefully I'll have github figured out before too long.... lol

You are welcome 😉

Re: Hyperfine bed leveling?

Maybe i am off a bit or skipped the info on this thread but how do you interpret G81 outcome?
I would like to add G80 abcdefgh to my starting gcode cause i need to offset the nozzle more than 99.
I get data in 7 rows and 7 columns and i don't know how to work with that.

Much appreciated

My God... now we are using Satanic commands!
