Auto calibration and bed leveling G30A 多點多次自動校正

平台校正, 始終是3DP diy玩家的夢靨, 尤其是 deltabot類型的機種, 除了平台還有三軸連桿運動帶來的高低誤差等問題, 網路神人多, 而且大方不藏私, 造福大眾,已不是欽佩所能形容的.


由RichCattell改寫的 marlin firmware, 增加了許多自動校正功能, 而這些校正在手動的情況下是很難達到的. 目前的版本是 1.0.4 , 在此向RichCattell的無私奉獻致敬, 以下是他的校正功能部份說明:


A new version (v1.04) of my Marlin firmware update (with auto-calibration update)  is now available at the following location:

https://github.com/RichCattell/Marlin/releases

I thought I would start a new thread with some instructions for its use as I have had lots of questions about this and the old thread is getting quite long and hard to search through!

This version has a much improved auto-calibration function which will hopefully be able to cope with many more printer configuration errors than previous versions were capable of resolving.

The auto-calibration can now automatically adjust the following printer configuration variables:

·         Delta Radius

·         Diagonal Rod Length

·         Software Endstop Offsets

·         Z-Height Correction

·         Tower Position Error Correction (independent Radius and Radial position adjustment for each tower)

All of these values can also be changed manually if desired using the M666 command .

除了原本的G29功能外, 透過G30 A 指令,經過數次Loop自動偵測上述校正項目後, 首層列印已完美呈現, 不再高高低低, 完全改善手動校正無法達到的精準度, 當然前提是你的組裝也不能太2266, 如果依照組裝說明與要求完成的機器, 配合神人的韌體, 不能說無敵, 至少也打通任督二脈, 因為沒有最好, 只有更好:-P
