Which board in Marlin?

[AFewSkroosLoose]

This is my first time in Marlin. Under board choices, there is GT2560 RevA and 2560 RevA+. I have GT2560 Rev B which is not an option.

Do I use RevA+ for use with BL touch (more similar to revB, yes?)

Also, is there a diagram or picture of RevB board anywhere for reference for all connections and what they are exactly for?

Thanks.

Hi


I won't help you when choosing the controller board.
Just because I don't know them practically.

I can show you the place where you will get the schematic diagrams:

• Rev B

• Rev A+

If you can, wait with the purchase. Currently in development is the next version: GT2560 v3.0
Controller will have very interesting possibilities, many connectors with planned different functionality have been added.

Hey,
I just got my brandnew A10 yesterday and looked on the GT2560
it says rev 3.0! I'm a complete newbie... so what are the new features?
I want to update my firmware soon - it is still 1.1.8.
I will post news as soon as I know more
cheers

Hi


In order for you to enjoy the new features of the controller board, they must first be programmed.
When the firmware is able to use the hardware, you will only be able to use it.

A few things that attracted my attention:

• filament detector

• Led lighting

• 3d-touch

funny. my printer came with a filament detector and it's already working
even tho I'm running marlin 1.1.8. so that is already implemented.
what also surprised me was that my version of the hotend cage had already a BLtouch
mount preinstalled. so I better be careful when updating the firmware...
I guess I will lose some features if I don't manage to set it up.
Quite surprising that Geeetech isn't communicating much about what it is
implementing and which version of GT2560 goes into the newest A10.
are there any other forums to find more info?

If you want to use 3D Touch, remove ''//" of this four definitions :

Code: Select all

00653 : //#define BLTOUCH  
00887 : //#define AUTO_BED_LEVELING_BILINEAR
01024 : //#define Z_PROBE_END_SCRIPT "G1 Z10 F12000\nG1 X15 Y330\nG1 Z0.5\nG1 Z10"
01047 :  //#define Z_SAFE_HOMING

modify:

Code: Select all

00732 : Z_CLEARANCE_BETWEEN_PROBES  0

to:

Code: Select all

00732 : Z_CLEARANCE_BETWEEN_PROBES  5

Then upload the firmware.

that is exactly what I wanted to know

I will post my experience.

Are you sure about this? Y330 seems to be out of range.
