Geeetech

Trying to set-up a GT2560 A+ board and a Geeetech 3D Touch leveling probe. The instructions on the site show an earlier GT2560 board with a combination of 2 pin min endstop plugs and 3 pin max endstop plugs whereas the A+ board has only 2 pin plugs for all endstops. My question is; where does the three pin brown-red-orange wire plug go? Power(red) and ground(brown) could be moved to an unused fan plug but where does the orange signal pin go?

According the directions you have to remove the 2pin plug from the GT2560 board and solder on the 3 pin plug that is provided with the level sensor. If you look closely you can see that the 3rd pin is location is on the board but ony 2 pins were attached at the factory.

Unless you have the 2560 Rev A+! If so it has the 3 pins already on the board!

Please help me, my printer Geetech prusa i3 pro B take probe only from middle of the print table !! How do i set up to take probe from all four corners of the table ?! thx

Have you made the changes in the Firmware for the number of probe points and the locations on the bed to pull them from?
Here is a link to the Wiki page with the settings you need to change. http://www.geeetech.com/wiki/index.php/ ... re_Setting

Hope this helps.

Has anyone got this working with the GT2560 A+ revision board ( that already has the servo pins next to the temp sensor sockets).

The link referred to has the wrong pin assignments for the A+ servo. It also has probe positions for a i3 style machine not a tripod.

I used the NUMSERVO, ENDSTOP, ENDSTOPANGLES as per the document.

The servo of the A+ board is on pin 11 . ( not 32 as suggested)

I had to reduce the number of calibration points to 4 as I was getting an error during compilation that the probe area was outside the probable area.

I can get the touch sensor to move/reset using the M280 commands. I can also see the Zmin input change from triggered to open if I force the sensor into the error condition ( lower it and then hold it retracted till it starts flashing. When I try to G29 auto level, I get a new error "? probe is out of range".

Would love to hear from someone who has got it working on a dual extruder G2S with the GT2560 A+ board.

thanks in advance.
