Latest stable Marlin for Geeetech i3 Pro B

[NiklasO]

Hello,

Here is the latest firmware for the i3 Pro B.
As of writing: 1.1.4

It is configured for BL/3DTouch with the ORIGINAL mount.
If you are using any other way to mount the sensor, you need to change the following values to reflect yours:

Code: Select all

#define X_PROBE_OFFSET_FROM_EXTRUDER 4  // X offset: -left  +right  [of the nozzle]
#define Y_PROBE_OFFSET_FROM_EXTRUDER -44  // Y offset: -front +behind [the nozzle]
#define Z_PROBE_OFFSET_FROM_EXTRUDER -1.4   // Z offset: -below +above  [the nozzle]

How to find your offsets, look at "Part 5" here:
http://www.soliforum.com/topic/4714/aut ... -level-23/

If using GT2560 A+, set SERVO0_PIN from 32 to 11 in pins_GT2560.h.

If you don't want BLTouch, comment out the following three values in Configuration.h:

Code: Select all

#define BLTOUCH
#define AUTO_BED_LEVELING_BILINEAR
#define Z_SAFE_HOMING

Thanks!

Good job!

Thanks for your great job.

Maybe this is not the properly site to write this but i try this firmware and others and my 3DTouch from geeetech doest work. When the printer is turned on it does the self test and it extends and retracts but when i want to do a bed level, it doesnt extends so fails all the time.

I dont know what to do. I have a GT2560 Rev A+ so i change the SERV0 pin has you say and nothings works.

Thanks for your time.

Flashed fine on my Pro B without probe (after making the changes above and entering my Z/E steps).
Will test a print later.

Thanks for this NiklasO

Thanks so much for a fantastic firmware. Great with new features etc, compared to official old Marlin firmware.

I have few minor issues, and so far I have not been able to track down if this issue originates in the printers firmware or in my slicer.

1:
From time to time the printer does not print the file on the SD card. Printer heats and autolevels. From there it does nothing. Only percentage completion rises with about a percent per second. No movement or extrusion. At one file I started the print again, and then the printer started printing correctly.

2: Autolevel. The default mesh autolevel was creating values that where height was incorrect, and I was unable to print, despite calibrating height several times. Changing to 3 point calibration solved this. Also this makes the calibration much faster.

A tip for other users: I have the GT2560A+, but had to change the SERVO0_PIN to 32, in order to make this firmware work. (I initially changed this to 11, but this didnt work, so I had to change this value back to the original).

hmm, my auto home seems to send the head to the center of the bed when homing Z (after homing X & Y correctly)?
Please note that I am NOT usiung the 3DTouch.

My Settings:

Code: Select all

// Travel limits after homing (units are in mm)
#define X_MIN_POS -15
#define Y_MIN_POS 5
#define Z_MIN_POS 0
#define X_MAX_POS 200
#define Y_MAX_POS 200
#define Z_MAX_POS 180

And this:

Code: Select all

// @section homing

// The center of the bed is at (X=0, Y=0)
#define BED_CENTER_AT_0_0

// Manually set the home position. Leave these undefined for automatic settings.
// For DELTA this is the top-center of the Cartesian print volume.
#define MANUAL_X_HOME_POS 0
#define MANUAL_Y_HOME_POS 0
#define MANUAL_Z_HOME_POS 0

Any ideas how to fix it?

That's right. Adding it to my post.

Support for GT2560 has been merged in to Merlin dev now. Just need to wait for next release to have official support.

Hello and thank you for the firmware.

What should I do with an echo:SD init fail error.

My board is hanging on echo:SD init fail and the LED will not power on. I'm using a GT2560 A+ board and made the following changes.

SERVO0_PIN from 32 to 11 in pins_GT2560.h
comment out the following three values in Configuration.h:
#define BLTOUCH
#define AUTO_BED_LEVELING_BILINEAR
#define Z_SAFE_HOMING

Here's a photo of the LCD/SD card board.

Hi,

How did you add the "change filament" and statistics of the printer (how long time/Much filament used etc) to the Marlin FW? Is this a custom fork? - Reason I am asking is that I cannot find anywhere references to this in the Marlin FW.
