Thank you William,

I now have a problem with getting the 3D Touch to work now I have all the wiring done.
The voltage I have at the sensor is as follows:

[Orange 4.87v Red 4.61v Brown 0v]
[Black 0v White 5.02v]

I have altered the original Marlin Firmware from the website:
PI3A Pro(for the upgraded kit using lead screw).zip
As per the instructions on:
https://www.geeetech.com/wiki/index.php ... ing_Sensor
and when I try “Verify and Compile” on Marlin Arduino 1.01 I get the following errors:

Marlin_main.cpp: In function 'void servo_init()':
Marlin_main.cpp:571: error: 'servo' was not declared in this scope
Marlin_main.cpp: In function 'void deploy_z_probe()':
Marlin_main.cpp:1286: error: 'Servo' was not declared in this scope
Marlin_main.cpp:1286: error: 'srv' was not declared in this scope
Marlin_main.cpp:1286: error: 'servo' was not declared in this scope

Marlin_main.cpp:1605: error: 'servo' was not declared in this scope
Marlin_main.cpp:1708: error: 'servo' was not declared in this scope

I had to make the adjustments in Configuration.h and pins_ULTIMAKER.h

I have included on Google Drive, the original Firmware file:
PI3A Pro(for the upgraded kit using lead screw).zip
https://drive.google.com/file/d/1auraAh ... sp=sharing

And the modified Firmware file:
I3PROA_Marlin.zip
https://drive.google.com/file/d/1yPFwaD ... sp=sharing

Please help as this is starting to get frustrating.

I am having a problem with getting the 3D Touch to work on my Geeetech I3Pro A

I have used the command lines tests and no faults noted :(

The voltage at the wiring feeding the prob is:
[Orange 4.87v Red 4.61v Brown 0v]
[Black 0v White 5.02v]

But when the 3DTouch is connected, it does not light up or work.
The voltage at the solder points on the 3DTouch are:
[Orange 1.76v Red 1.19v Brown 0v]
[Black 0v White 1.77v]

I have also checked the original voltage checkpoints and the voltages have dropped there too
Any ideas?

I had to make the adjustments in Configuration.h and pins_ULTIMAKER.h

I have included on Google Drive, the original Firmware file:
PI3A Pro(for the upgraded kit using lead screw).zip

And the modified Firmware file:

Please help as this is starting to get frustrating.
still not working :-(

My pin.h file does not have the settings in so I updated the settings in the pins_ULTIMAKER.h file. my pin file contents are

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

Post by derekoh » Mon Feb 26, 2018 12:33 am

Help! I've purchased a BLTouch from Geeetech and am trying to install it on my i3 X Pro (with GT2560 Rev A+ board).

I've wired it up correctly, and it lights up and does the couple of test lowers/raises when I power on. I've made all the changes to the firmware and uploaded that. The light does come on when I push the pin up, and goes off when I pull it down. The M280 P0 S10/90/120/160 commands don't do anything, and M119 is showing Z_MIN always "open" (If I disconnect the wires from the BLTouch, then Z_MIN changes to "TRIGGERED". If I then touch those two wires together it will switch to open), so it's not a wiring issue.

Any ideas what could be wrong?

In the configuration.h I setup the following:

#define ENABLE_AUTO_BED_LEVELLING
#define AUTO_BED_LEVELLING_GRID
left/right/back/front - all defined ok

G29 moves to the various positions and tries to test (but grinds into the bed because of the Z_MIN issue)

in pins.h (under the Ultimaker section):

#define Z_MAX_PIN -1
#define Z_MIN_PIN 30
#define SERVO0_PIN 11 (as I'm using the 2560 A+ board)

Any ideas?

Hi!

I have the 3D touch sensor working but I'm having leveling problems.

[img]https://lh3.googleusercontent.com/QSOSF ... 23-h917-no[/img]
The two pieces have been printed at the same time but in different parts of the bed. The left one on the center and the right one at the right of the bed. I don't know what can be wrong, any ideas?

Thank you!

Am I the only one having calibration problems? I can't print large pieces as the left part and the right one are differently calibrated.

I got my new Geeetech 3DTouch Automatic alignment sensor so I put it in the video in the second layer the needle falls down if I pushed 2 things so soon and is about 4 layers to the needle pulled up.
I can not figure out why the needle goes down the other way up the press, thank you for your advice and help

Has anyone yet got the 3D Touch working on the Aluminuim Geeetech Pro A with the GT2650+ board?
If so please could I have a copy of your firmware as this has been doing my head in for 6 months now!!!

I've purchased a Acrylic Prusa I3 Pro B printer, built it (with multiple nights of cursing an swearing ;)) and am now trying to add the 3D touch sensor. I've got it responding to commands after finding out the GT2650 A+ already had the 3 pins necessary and i didn't have to de-solder the zMax port!. But when it's doing a G28, the X & Y axis home and end-stop, then for the Z axis, the bed centres properly for the sensor to strike the middle of the bed but the hot end just strikes the print bed first and it carries on driving into the bed. The pin on the sensor is down and extended but its not long enough to make contact with the bed first before the hot end. As a result if i don't stop it the motor would continue driving the hot end down. If I put something in the way to strike the pin first the sensor seems to work as expected and the z-min is established. Is there something else i should be adjusting on the extruder, or printing a new bracket with a bigger spacer?

The image shows what i mean. You can see the pin is down, the hot end is touching the bed but the pin is still over a key's widths away from the bed so its never going to strike it first. The following image shows what i mean.

Hi, try to adjust the hight of hotend to decrease the distance between hotend and extruder carriage, then relevel the bed.

Hi,

Thanks got it working and had a few prints going but then noticed extruder motor was dropping steps and looks like it was too low to the bed.. re-calibrated several times. Then did several G29's in succession without changing anything. The Z readings were +- .3 mm each read so no wonder some times it was choking the extruder. Also during two prints the pin randomly dropped... Completely fed up with it and going back to manually levelling the bed for more consistent reliable results.. Can't say as i rate this piece of kit at all. Waste of time and money. :(
