Thanks,
A most hopeful thread that says it all.

No support for multi tooth thread mill cutters in the new version, was in the old version.

Also Mill Wizard is a program registered to Artcam, confusing and possibly in violation of the name ?
If you search for Mill wizard you get 10 hits up first for Artcam

Hood,
i was under the impression that the ab channels weren't working on the SS for threading ?

Will run first thing in the morning, midnight here and the bloody workshop is haunted anyway.

Last report of the 2HP motor geared for 600 rpm plus Hoods large spindle motor lead me to thing it's down to feed back from spindle speed.

Problem is most small modern machines use electronic variable speed of some description, unfortunately a reduction of speed will not give an increase of torque like the older pulley / gear driven machines.

Well my spindle speed sync is definitely ticked.

Hood, Your machine is probably the worse one to do any testing on. With 25 Hp at the spindle driving thru a mechanical gearbox it shouldn't alter speed by a tenth of a rev when threading. What are you using for an encoder ?

Has anyone other than Steve Blackmore tried using a normal encoder with Channel A and B on the Smooth Stepper ?

Rich,
Can you clarify that this test was with the smooth stepper and on one index pulse or from an encoder, if so how many count encoder ?
I was of the understanding that the SS was threading OK and it was just the parallel port that was having problems.
