The following message appears when running qtpyvcp, is there a way to get it fixed?

try to set servo period 100000 higher
tune your system to get a better latency

Are you using a parallel port?
If not, you should remove the line containing BASE_PERIOD.
This and the reply before will not fix the issue you are having, sorry i can not help with it.
