[GreenKeys] Printer won't align model 15

[Ralph Mowery]

One other thing are you sure the printer is a 60 wpm and not some other speed ?

 

When you say 22 second delay I am sure you mean 22 milliseconds.   Also that 22 delay per bit I am sure you mean that each of the bits are 22 ms and not a bit, then 22 ms and another bit and a 22 ms delay.  Are you keying the loop at around 100 volts or more ?  The printers do not like to work correctly with a much lower voltage.

Dear all,

 

My printer won't seem to align itself to the datastream it is being sent no matter how I adjust the speed adjuster on the side, what do you recommend I do to trouble shoot it? It prints perfectly fine when it is printing to itself. I currently have it hooked to an Arduino which is sending out RYRYRY in Baudot. To eliminate the question of is it the code, it is currently has a 22 second start delay, 22 second delay per bit, and a 31 second ending delay. That is currently being run through a solid state relay capable of switching at that speed. I know it can do this since it works with the keyboard when moving locally. Furthermore, the letters it prints are always the same depending on the speed setting, (although wrong) so it's not like there's a mechanical issue.
