3D Touch Sensor:Auto-levelling for Geeetech 3D printer

[pes0001]

Thanks for the reply. I am using 1.0.2
Where to download newer version?

[edautz]

You can use the stock Marlin. Release versions are found here: http://marlinfw.org/meta/download/
There is also a Marlin github available with the latest sourcecode. My printer is running by Marlin 1.1.3. It runs fine.

You have to configure Marlin and compile it for yourself, see the Marlin site, this topic or numerous other topics for the configurations details about setting up and configuring Marlin with your specific printer settings.

Ok so I upgraded to marlin 1.1.4.
got another gt2560 board.
downloaded the marlin sw for the geeetech using the 3dtouch.
Did not work off the bat. set the #define servo0 pin from 11 to 32. this allowed me to send m280 p0 s10 /90/120/160 and that worked.
Using the 3 pins in Zmax (ground, signal,12vdc positive.) Zmin has white wire to outside edge of board as per instructions. (turned around flashes fault on 3d touch)
the problem I am having is that when I send a Zhome, the Zaxis goes up probe goes down then Zaxis continues up and does another probe.
It is as if it sees something in the sensor path.
IF I send a G29 it will not move the Z axis down and probe but moves it about 50 to 75mm up then probes in mid air.Here is a partial copy of my config .H file[/size]

I think you should check if the Z min connection is OK. And you can use the M119 command to check the Z-min statement. if the Z-mn connection is OK, you should reverse the Z direction of the movement in configuration.h file.

[pes0001]

inverted the z axis stepper to true.
Axis now moves down but probe will not go down, so nozzle crashes into bed.

Decided to swop out the 3Dtouch with another one.
Problem solved, had to change the z axis stepper back to false.

Wonder if they will exchange the 3d touch.

geeetech i3 pro c und auto levelling
hat jemand die marlin dafür `?
wo es feritg schon ist

komme damit nicht klar was ich und wo eintragen soll
Geeetech i3 pro c and auto levelling
Someone has the marlin for it `?
Where it is feritg already

Is not clear what I and where to register

[edautz]

You can find Marlin here: http://marlinfw.org/meta/download/. You have to configure it and to compile it for your printer and to use auto bed leveling. You can find enough examples in this forum and on the Marlin site.

[dj3d]

habe gesagt da ich davon keine ahnung habe wie man das macht

I said that I have no idea how to do that

[edautz]

This is a forum and not a course to setup and flash Marlin for newbies. Go to study the Arduino IDE and Marlin documentation to find out and to get the basic knowledge you need to get the job done.

danke für solch ein spruch was keine hilfe ist
hast wohl was dagegen das jemand geholfen wird

Thank you for such a claim which is no help
Have probably something against the someone is helped
