What Could be wrong?

i have this problem a while ago wherein i cant program the picaxe 28x1..

when i plug in the battery(4.3v) the servo jerks alittle bit so that was an indication that the battery is workin...

 

but i cant program it...

 

i tried to put 5volts the servo doesnt jerk and still i cant program it...

 

i tested the programming cable its fine....

 

 

but after 8-10minutes... it suddenly works! what could have been the problem?

 

hope that doesnt happen again..

when in doubt…
Reset the board but ALSO close the program editor and then reopen it, this usally works for me.

Also to make sure are you
Also to make sure are you using the same power source for the servo and the board? If you are using multiple power sources tie the grounds together or it won’t work.
