Re: Help Fixing a Sanguinololu After Mistake
It's hard to tell from the photos, did you have the stepper driver installed when the arcing happened? Or was it also burning without the stepper driver?

Yes, you have to replace the firmware on your sanguino. There is an upload button in the arduino ide tool bar (arrow pointing right), that sends the new firmware to the board.

You need Arduino 1.x. Make sure you install the sanguino 1.x patch from here. You also need the LiquidTWI2 library, as described in Configuration.h. If after this you still have compile errors, post...

Yes if you want to home to max you need to use a max endstop and change the homing direction. Just change the pin definitions in pins.h to swap the MIN and MAX pins.

Thank you very much! It is now homing correctly to the top. However my X axis stepper is stil going only one way
View ArticleRe: Sanguinololu homing/end stop problems
In order to be able to home the Z-Axis to MIN or MAX you need 3 conditions: either MIN_HARDWARE_ENDSTOP_Z true and Z_MIN_PIN > -1 and Z_HOME_DIR-1 or (MAX_HARDWARE_ENDSTOP_Z true and Z_MAX_PIN >...

Is it possible that something happened to your power supply and the motors are not getting enough power? Can you try a different power supply and check that the power cables have good connection?

so i tried a new power supply it was a 250 watt 12volt-14amp and the motors twitched just as much as with the other power supply:(
View ArticleRe: Why are end stops NO instead of NC?
The idea of NC endstops is that a broken wire is detected immediately. If a connection breaks using a NO endstop would cause the homing routine to smash the axis against the limit and never stop the...

I assume your stepper drivers are good, you mentioned they worked at some point, it would be highly unlikely they all burned out at the same time. Since you have temperature reading and host...
