Really weird because your documentation clearly shows pin 16 as an output pin so EStop cannot work, yet it does ?

Something like this would be good.

Say 30mm x 30mm, Stepover 0.5mm, Feedrate 20,000 (not inverted)

Certainly a mystery.
Could you possibly post a picture of the result and a copy of the test image you are using please ?

You could well be right here.
Increase your stepover so you can study each individual line of the images produced.
Because the plugin operates in duplex mode (bidirectional) then if each image is produced by alternate lines it would indicate too great a delay in firing the laser after receiving the Mach trigger pulse.
(Not sure I have explained this very well).

ntlaser,

Do you have "Sherline 1/2 Pulse mode" checked in Ports and Pins ?

The only enabled inputs are Probe and Estop. Probe on pin 10 and Estop on pin 16.

Vicrider,

There seems to be some confusion regarding pin numbering - at least I am confused. 
EStop has to be on something other than pin# 16 because that is not an input as far as the one parallel port setup is concerned.

Found this one in my Mach folder - I have no idea of it's origin.

I have been following with great interest and you really don't need any help because you are sorting it out just fine.

( hint:  if you reduce the acceleration in motor tuning or use 'exact stop' mode instead of 'constant velocity' in general configuration it may help )

Even a plain threaded rod with nuts won't have 1/2" backlash.................something is loose.

Rich,

You have to think outside the box.
An axis which is tight in one direction only can loose steps in that direction and then be 1/2" out when it returns, nothing needs to be loose.

Could it be that there is some tightness or binding in the threaded rods which is greater in one direction than the other ?
