Initial comments...
On your motor tuning page you have no pulse width set for your step and direct.... Are you using a motion controller or the parrallel port?
Your machine is in inches, and you have a X, Y and Z set at 5833 steps / inch, and the machines maximum velocity set at 160 inches / min.... so, i'd suggest
changing your machine kernal speed from 35kHz down to 25kHz.... given 5833 x 160 / 60 = 15.5khz (maximum step speed).
I'd also suggest changing the step and direct pulse widths to 5usec (which would be 100kHz and seems to work with most stepper drivers quite well).
I'd also suggest changing the lookahead on the configuration page to 200 (2nd column from LHS).
The 5833 steps per inch is confusing me a little .... as I'm not sure how you worked it out as it does not seem to align with either a metric or imperial pitch (unless you've got gearing on the machine)
either (1 / 5833) x 200 = 0.034287673..... (bit of an odd number... indicating it may be a metric leadscrew pitch... but)
5833 / 25.4 = 229.6456929133 .... again... little odd number
1 / 229.645.... x 200 = 0.87096908
so maybe a metric pitch of say .... 1.75mm threaded rod.... (on 1/2 stepping mode) ... still a little off
If it is 1.75mm pitch threaded rod... it should be 5805.714285714.....
[I've never done it... but if you have metric leadscrews, it may be beneficial to set them up as such, and then add a "G20" code to the initilisation string on the config window and also prefix your code with a G20 code so that the machine will appear to be an imperial machine and it will do all the correct math internally with minimal rouding errors ... maybe worth a consideration / comment by some of the more experianced about as to whether this would work]
