Geeetech

Hi all,

apologies if this has been posted before.

I purchased a GT2560 rev A+ control board from your Amazon shop however on installing this as a replacement to a defective board, and loading the marlin firmware I am getting a "G28 Z forbidden" message when truing to home the z axis also the Z position is displaying 5. when I enter a m119 Gcode I get the following result: X_min open, Y_min open, Z_min open. my printer is a Geeetech pruse i3 pro b with Bltouch auto bed level.

the marlin firmware is the latest and was working perfectly on my previous board.

I think there is a way to clear the EEPROM memory in marlin - maybe some bad config values?

I think so that the author share something about Forbidden error which comes on our computer or tablets screens due to some wrong commands. But now we have some amazing websites which helps us for solving our problems. One of the best HERE website is sharing here for buying water filtration systems.
