Geeetech 3DTouch auto bed leveling sensor for 3D printer
« u: Svibanj 24, 2017, 07:46:02 poslijepodne »
Omogućava 3D printanje čak i na podlogama koje nisu u potpunosti iznivelirane, pogledajte YouTube video:
t=4s

Dolazi sa isprintanim nosačem za Geeetech i3 Pro B printer, ali je moguće isprintati (besplatni download) za veliki broj kompatibilnih printera:

3DTouch is an auto leveling sensor for 3D Printers that can precisely measure the tilt of your print surface. It can greatly improve the printing precision of your 3D Printer.
 
3DTouch features simple, smart and precise. It could work with nearly any kind of bed materials, such as glasses, woods, metals and so on.
 
The main functions and controls of 3DTouch are the same as most auto bed leveling sensors, which consists of a RC servo and a micro switch, thus, 3DTouch can be used on almost every 3D printer control board.
 
By using progressively designed solenoid and hall sensor, 3DTouch can integrate high precision in such a simple structure. To make it more user-friendly and to bring you more enjoyable printing experience we add many smart functions such as self-test, false alarm, alarm release and test mode for M119.
Features:
1 Simple
3DTouch can be easily applied, since it has a small and simple structure. Gathering information & firmware setting will be an easy task, because 3DTouch works as usual auto bed leveling sensor.
 
2 Smart
Self-test: The push pin is operated three times to test when the power is on
Alarm: The LED light blinks if a problem found on a self-test or on an operation
 
3 High-precision
3DTouch’s Standard Deviation in repeatability is around 0.005mm, at that precise.
If you choose 3DTouch, your 3D printer will be high-class masterpiece, giving you an enjoyable experience.
 
4. Innovative Solenoid: Ultra Power Saving
On idle state, while the push-pin is whether pulled out or retracted, there are not any electric current flowing on solenoid, and standby electric current in the whole device is below 15mA on average, whereas on working state, while the pin is moving in sudden about 100ms, under 300mA flows in the device.
Low power consumption even further drops joule heating, preventing from heat problem.
 
5 Technologies
3DTouch consists of Atmel ATtiny13A, solenoid, and a push pin.
 
6 wide Selection of Bed
3DTouch does not uses either optical, nor proximity (inductive/capacitive) sensor.
3DTouch is controlled by Hall Effect, providing high precision. Thus the bed material can be selected freely.
 
7 Optimized structure:  Larger Build Size
3DTouch is a small and technology-intensive one. Build size can be set larger than other existing auto bed leveling sensor.
3DTouch uses existing RC Servo motor signal intactly, so just plug 3DTouch on the same pins after removing servo motor.
 
Please note that:
3D touch auto leveling sensor is not plug_and_play; you will need to do some modification to your
firmware and for some control board,

Zadnji put kada sam ovo gledao cijena je bila oko 40$ što mi je bilo previše. Sada sam slučajno na AliExpress-u naletio na cijenu od 20$. Evo link ako koga intresuje.

Update sto se tice ovoga.

Postoji BLTouch koji je u biti orginalni senzor na ovaj fazon i kosta oko 48$
Također ima gore navedeni 3DTocuh koji je kineska kopija i košta 20$.

Ja sam narucio ovaj 3DTocuh sa Aliexpressa. Nakon prve instalacije senzor nije radio kako treba. Ispostavilo se da kinezi koriste obicni wire heat shrink da ogranice koliko ce igla ispadati. Na mom senzoru nisu to uradili kako treba pa je igla ispadala previše, solenoid nije imao snage da je povuce nazad. Ja sam dodao još komadic heat shrinka i nakon toga sve radi super.

Marlin 1.x je jako lako konfigurisati da koristi senzor, bukvalno odkomentarisati jednu liniju u konfiguraciji, sve ostalo je spremno.

I za kraj najvažnije, senzor radi odlično. Pošto imam Prusa i3 sa pleksiglas ramom, uvijek sam imao problema sa prvim layerom. Cini mi se da kako se bed zagrije da se sve malo pomjeri. Sa ovim senzorom sam prvi put otkad imam printer uspio naštimati da mogu pokrenuti 10 printeva za redom i da svaki uspije bez ikakvih problema. Prije ovoga sam koristio induktivni senzor, ali mi on baš i nije bio pouzdan.

hvala na informaciji, ni ja nisam imao sreće s induktivnima...
