Geeetech

Hi

I am having problems with my G2S printer
Last night i updated the firmware on my printer via arduino and nothing special there.
The change was the name shown in the display from Geeetech to my own name.

But after the update and all looked good the printer have started to do weird stuff.
I have uploaded the original firmware again with 0 changes but no luck.

when ever i click "home all" in the printer menu the stepper motors starts to move VERY VERY slowly in one or the other direction and i have to reset the printer
I have tried to udload a repetier firmware i once used that also worked, it does sort of work and the motors run ok when i try to home it here but that firmware / config is something i did not want to use as i could never get it working 100% okish and went back to the stock firmware that i have been running until last night.

any idea why the stock firmware makes the motors do what ever the *beep* they are doing..


Video of the issue can be seen here, turn volume up to hear the stepper motors go very slow.

Hi，from the video, the motor does not rotate. This should not be a firmware issue.
You can swap the motor wires or drive to see if they have problems.

The motors are rotating just very very slow

if i upload the repetier firmware they move like they should.
that firmware how ever have a problem with the extruder and other stuff how ever there is nothing wrong with the motors or wires to the motors.

when i upload the standard firmware that always worked for me it goes back to the problems with the motors.
i have tried to just wait and see what will happen and at some point it will get the endstop and stop, then it might print from the SD card like everything is ok then if i stop the print and make it go home it will start over with the slow movement of the motors
and control from the computer is impossible as it will also result in the slow movement of the motors

here is a copy of the firmware i am using and always have been using when it was working

OHHHHH!!!! *BEEEP** ARGGGHHH!!! CRAP!!

Is it possible that the board could have been damaged by a wrong firmware.
I just remembered that i when i created the repetier firmware that i at first selected a board that where RAMPS 1.4 compatible.
when i uploaded the firmware the beeper on the board started to beep loud and the stepper motors started to go down in small jumps.

i turned off the board and uploaded the correct firmware and after that the standard firmware and not its at a place where it wont work with the standard firmware for the printer and runs really buggy with the repetier firmware.

but should the board not clear it self completely when you upload a standard firmware again ?

Seems like i have fixed it...

Thanks to all the information on your forum WOOOHOOOO!!!

needed to clear the EEPROM with GCODE M502 and all is well
