Hi All:
New plugin is online. Bugs we're working on now..
1) Jogging is not decelerating properly when jog speed is changed. This affects things liek the shuttle jogging,
thats number 1 on priority, and we'll get it fixed up soon.
2) Spindle control, there is none, we'll fix that up too.
New plugin has FRO from 100% to 0%.. and homign and limits appear to be fine..

Jogging now working after version upgrade, was using Ver 2.0061 now using 2.62A
Got my homing working with the PlugIn posted last night.
Axis directions OK on Y and Z but still problems on the X. (Had to change Dir Low Active setting to get it moving correctly)
Axis speed is showing up in the DRO as almost twice the actual speed, ie if I do a G0 it will show as 4000 something mm/min instead of 2400mm/min, could be due to not having motors tuned?
Up/Down arrow keys for axis movement when on motor tuning page still dont work for me so cant tune motors.
If I jog one way then the other before the axis has finished decelerating the motors will stall (steppers) This could be the decel bug mentioned by Art above.
All in all a vast improvement over yesterday, keep up the good work Art and Greg :)

Good, at least joggin is OK.. at least on yours, we're working on a fix fro smoothness of decel..
Direction is wrong on X?? Hmm. OK, Gregs looking into that one..
Axis speed is perfect here.. What controller frequency are you using, and axis max frequency??
We're aware of the stall, that will be fixed shortly, the tuning however will probably never tune while in the window,
the system cant move at the new numbers till it flahses the new information to the SS, so thats one thing that wont work.. tungin has to be by trial and erro at the moment..
Thanks, Good reports,

my frequency is 45Khz and 64Khz in SmoothStepper config.

well got mine working, found out that if you had turned off the device selection that pops up in the beginning, you are unable to load the SS. I reenabled it and now mine is working good.
So, note to you that may have turned off your device selection and then tried to install the SS, go and reenable the dev selection.

The X direction wrong is not a hard bug. Mine runs in correct direction (i.e. as PP). Accidental change in Ports/Pins perhaps?

Got mine yesterday, work fine.
Started the 3d test this morning with a 250 000 small segments line program. The first show the same performance as the Grex, slow and jerky, second test, we raised the look ahead to 200 lines and it not change so much but a little better..
Does the CV settings affect the performance as much as the parallel port set-up??
But the unit seems to be reliable, i'm running windows, web, email, 3d programming stuff etc... while the unit is running!!!
More testing to come...

Thanks for the report. There shoudl really be no difference from a printer port. The ss doesnt suffer form any lack of transfer. Make sure the Setttings page has CV angle and CV distance turned off, inadvertanlty the install turns them on and CV will suffer..
If you can, zip your file and send it to me so I can test here as well, we wont tolerate any 3d segmentation issues in the end, because in theory
the SS should be as capable as the printer port in all programs..

Well, the CV angle and CV distance are turned on, i will run the file again!!
It's a five hour file!!
I sent it to you by email in zip.

I have run a VCarve Pro file with lots of small segments and it is very smooth. Originally it struggled with G00 and G01 with a delay between them (same on PP but a shorter delay).
Art has fixed the delays in but systems in Mach3 2.62
The video at
http://www.castlewoodconsultants.com/Misc/PulseEngineCompare1.wmv
shows the code on PP and SS with and without the delay. It is streaming but being full motion at 24 frames per second so you can judge the motion takes a whlle to download - whole thing is 512 Megabyte. You need sound to hear the machine in action.
I have since doubled speeds but not yet videoed it.

A nice to have would be a way to change the FRO rate for each position of the outer wheel. from 0-7 positions i currently have 0=0% 1=2%,3=4.2%,4=20%,5=100%,6=200%,7=420%. the high percentage especially anything over 100% is not usable In my case, can we adjust the percentage values ??
