Stepgen spindle

Hey folks, longtime listener, first time caller.I have a small 3 axis mill which I've built, for the spindle I'm using a 1kw servo motor with a 94 tooth pulley stepping down to a 40 tooth pulley on the spindle. I've been trying to set this up as Stepgen controlled but the speed of the spindle is being limited. I'm a bit of a luddite when it comes to this and was hoping someone might be able to give me some idea of what my settings should be. I'm confused by how the top two figures come out of pncconf as low numbers the max_velocity and max_accel are usually 50ish or less after I open the ini file which then makes the servo rotate verrrrry slowly. 

The servo has a max rpm of 3000 so my final spindle speed should be 7050. Currently the tach on the servo driver shows that I'm getting 1190rpm but it won't go higher than that. 

- Should it be possible to run a Stepgen spindle at 3000rpm? 
- Is there any advantage to running an analog output instead? Thanks for any help, Giles 

I know how axis the ini settings are in revs per second rather then minute.
I bet pncconfcsets thecspindlecascrevsxper second too. 50 rps is 3000 rpm

P setting seems wrong to me for stepper. Shpuld be Like 1000 or so.
Peter could give you better advice there.
Also what mixrocsteos is the driver set to?

Actually, for a step/dir driven spindle I would set P to 0.
The FF0=1 will forward the commanded spindle speed
directly to the stepgen velocity.

If you set the stepscale to 1/60 the steps per turn of the spindle, the spindle
will be scaled directly in RPM.

So I did more looking into the servo driver and found that the factory settings for the steps/rotation were set at 10k. Same for the encoder. Could that explain why I was getting much slower than expected rpms out of the motor?

Pretty hard to guess...

can you post your hal and ini files?

Thanks, so here is a google drive with the Hal and ini files. drive.google.com/drive/folders/1m6BoVFtY...yYu1d4vq?usp=sharing
