Rambo Servo Setup for Auto Bed Leveling for Noobs

[sniffle]

Check the zennmaster videos on youtube... There is an option in the cobfiguration.h to allow going below software endstops and the x y or z can become negative in value.

i have entered my probe offset but now it wont compile
give me an error

This report would have more information with

enabled in File > Preferences.

these are my offsets

here is also my endstop settings
can someon have a look over,

here is my current config h file for reference
Configuration.h

[printbus]

avrdude is the tool used to program the flash memory inside the MEGA2560 processor, so that's where something is going wrong. Have you tried to upload from the Arduino IDE a second time? Have you previously been able to upload OK?

i have done it many times just fine, but just recently its been giving me these errors, every time now.

[sniffle]

what is the error it throws when you try to compile it?

edit: nevermind i cloned the git repository again and dropped your configuration.h into it. I know what is causing it, I had the same issue. Give me a few to test an idea, and i might be able to give you a fix and If it works for you i'll try to push a fix to the main branch as well to permanantly fix it. I'm at work so i wont be able to test it... you'll have to be my guinea pig :-P

[adamfilip]

Sounds good, thanks for your help!

[adamfilip]

Do you remove the manual adjustment springs once abl is working?

[sniffle]

The issue is in the grid point checking algorithm, that checks to make sure we aren't going to probe outside the bounds of the print surface. There is a preprocessor check that says you can't compare floating point numbers, and that is what is throwing the error. I may get Roxy in on this one sice i don't know C that well.

you can comment out that entire block of code, and it will compile/run but it may go out of bounds and the only way to do so is to manually press the endstop

I'm actually running Roxy's version of the firmware right now. I need to get this figured out...


I left my springs, I just don't adjust them anymore.


and speaking of roxy in case she reads this...

Roxy here is a link to the code in question as well as the error

ok i commented out that section and i flashed the firmware
I was able to home all axis but when i try and autolevel the prob tried to find Z off the table to far over X
