Hi,

Just discovered that since GT2560 V4.0, no offset option are available :
- no menu item : Prepare / Set Home Offsets
- no support of M428 GCode
- no support of M206 GCode

Any chance to convince development team that giving the ability to define in a permanent way offset (especially on Z) is ...

I believe that I have completed the challenge :)

Still the need to solder 2 connector on the board and assemble one plug for the second Z stepper (option Z2 has is dedicate A4988 driver : DUAL Z in Marlin)

Also discovered the two last pin values to obtain a full map of available pins (see above ...

UPDATE : Pending issues SOLVED
-> SD Card reader on LCD WORKING (replace pins_GTM32xxx file by updated one available on the google drive)
-> Mixer WORKING (but sure to apply u8glib library update as described below)

I wish to really thanks InnerBushman and Vertabreak ...

I'm currently replacing the GTM32 pro by a GT2560 RevB.

Why downgrade the board performance by regressing to a 16 bits ?

To be honest, I'm more looking for versatility (be able to print and laser engrave) than speed/performance.

Why the revB ? Because the connectors are mainly compatible with the ...

Hi,

Thank you for your fast answer.

Yes the printer is a M201 with a GTM32 pro VB board. I tried two version of FW (1.03 and 1.04) without improvement.

Numerous test with a lot of M and G command (delay waiting etc..) in interactive or SD card execution without finding any solution.
At the end ...

Dear all,

I'm trying to synchronise the start/stop of an engraving laser.

The code looks like the following :
M107 P2
G28
G0 Z50
G0 X127.6479 Y140.893923 F1200
M106 P2 S100 ; Laser ON
...

What is happening is the activation of the M106 P2 S100 (laser ON) just after the G28 (home completion ...

Nice the red color "(GTM32)" definitively help to understand the difference / border line between the two boards

Have a great day

Hey !

Firmware page is maybe a little bit cryptic :-)

Thanksfully a between bracket "(for GTM32)" is supposed to make the difference between the pro and the "not pro" (too bad, the not pro seems to be more powerful than the pro. :lol:

Just assembled my brand new M201.

Trying to challenge mu i3 pro C which is working like a charm but with a limited printing volume.

Everything worked as expected untit I tried to upgrade in V1.0.5.

Board is the new/last GTM32 VB.
-> connecting, putting jumper, loading and verifying FW loaded in ...

The profile which seems to be the most compatible is the Raise3D N2 Plus Dual

You still need to make the "size/setting" adaptation

Hope it helps
