I'm not sure if this is a smoothstepper or Mach3 problem, but here goes.
I'm bench testing a servo spindle with a G320 for my lathe using step/dir, all seems fine except the accel and decel. I have them set as low as possible, which the motor tuning graph shows 4 seconds but it accelerates to speed in a second or less and decels instantly faulting the G320. Actually it doesn't fault and reset, but the G320 just shuts down and I have to cycle the power for it to start up again.
In motor tuning, I have Steps per set to 1000 (250 cpr encoder) and velocity set to 3400, the rpm checks dead on throughout the range tested with a handheld tach.
I'm using the smoothstepper with the v015ogb plugin, Mach3 R3.042.021, Geckodrive G320, HomeshopCNC 850 oz/in servo.

Sounds like your "current" pot on the Gecko is set to low, and your clipping your Gecko on Accel/decel.

You need 015ogd for Step/Dir spindle with servo

Hood:
I'm using the ogb (OGB) version which is the latest on the ss site, is there an ogd (OGD) I missed?
poppabear:
I have the limit pot at max. However, it is a 72v servo and I have only a 60v PS, would that cause it?
Thanks,
Tim

Ah OK I was testing for Greg with a Servo Spindle and had a few Beta versions and then Greg gave me the OGD version, just presumed it was on the site. I will email it to you but use caution as although it works fine for me it may not for you.
