Geeetech

Hi!

I have a Geeetech a10m with latest GT2560 V4.1 board. This board comes with integrated A4988 drivers a no option to put other drivers on it. Also, drivers are "integrated" onboard with no regulator on it. This is the board: https://www.geeetech.com/gt2560-v41b-co ... -1180.html

With this in mind... wehat can I do to adjust current on this drivers? i want to chage extruder and I need to increase the current.

Thank you so much!

Sorry, because the driver is integrated, vref cannot be adjusted.

WHAT!!!!

It must be any way to do it! even with GCODE!

What kind of shit board are you selling right now?

My stepper is skipping steps because low current. If I cannot chage the current value i need you to change the board from a v4.1 to a v4.0

What about GCODE commands like M907 M908 M909 and M910 ?

Can't we set the current with this?

No news about this?

same problem here... the problem isnt the current is the frequence used... but for modifying it we need the oiginal marlin files (folder)used by geeetech for create the firm... if any could help.. ( i ve already try to make a new firm, bu machine crash many time....)
