Mendel auto bed leveling with an inductive sensor (No.4) : Marlin setting
auto bed leveling with an inductive sensorのためのMarlin Developmentの設定。
気前よく、プログラムを公開している、The current Marlin dev team consists of:Erik van der Zalm (@ErikZalm), @daid にとても感謝。
環境
- 3dプリンター：RepRap Mendel
- プリンターのマザーボード：Arduino Mega 2560 ＋ RAMPS 1.4
- Extruder：MK7，0.4MMのコピー
- パソコン：Windows 7,
- ファームウェアー：Marlin.
- Auto bed leveling sensor：NPN inductive sensor
before start!
You need to measure dx, dy, dz for this setting. Where dx is the distance between the extruder and the inductive sensor tips along x-axis. And dy is the same but along y-axis. The dz is the distance between the extruder tip and the heated bed when the z endstop is triggered. The other ward, the printer move this dz distance deeper to the heated bed when printing.
Well I hope the following figure make sense to you. It is noted that the direction x or y or both are not important and it is not necessary to match with yours.
My case, dx = 33.5mm, dy = 0mm, dz=0.5mm.

以上、誤字脱字の心配をよそに、
By the way, I bought a PNP type sensor so I gonna replace the NPN type to it. That case I do not need 12V to the sensor....
