Servo Jumping On Initialisation

The dreaded jumping servo problem has arisen again - just today. All servos in the robot are HDD. The servo on port D0 now jumps after connecting, to about 35 degrees instead of 90 degrees. If I move the servo manually when turned off, the centre position is still 90 degrees, so the sprocket has not shifted. My INIT script has not changed. That...

Default File Storage Address For BLOCKLY Files

Hi DJ, just a brief question: How can I change the default file address for storing / loading BLOCKLY files within ARC ? I need to store and load them in / from my central server, since - over the time - I am working on three different computers and always updating new software versions on these three plus the server is simply a time consuming mess...
