Re: Spindle Motor Recommendations

Hi Jim, I really like your 2hp mod. The PM motor is really disappointing where it bogs down so much. Are you still liking the conversion to 2hp? What about the fitment of a power drawbar, still enough room? I'm pricing out doing the conversion to 2hp. Can you send me the part numbers of the bearings...

Re: Using TT-1B for Z-ref

I just happen to stumble across the release notes for V4.64. There was a fix for the z-ref with a similar error to what I was seeing. Updated from V4.5 to V4.64 and it didn't fix it. So I went to the wizard and the yes for z-ref in Tool Touch off was set back to no. Changed to Yes and it worked. I t...

Using TT-1B for Z-ref (Resolved)

I installed the TT-1B to my Acorn. It works great for measuring tool heights in auto measure mode, except for Z-ref. I changed the option to yes to measure z-ref. Put in the TT-1B height. When I select setup,z-ref,auto, it says it cant find the probe. It finds it to measure the other tools. Centroid...

Re: PM-728 Conversion to CNC Teknic Drive Faults

No more drive faults on the Z axis. Will do the Y and X today.

Got the detail I needed from your pictures. Thanks.

I'm also a car guy. Doing a restomod on a 1936 Ford 5 window coupe. This machining stuff keeps getting in the way of finishing the car.

Re: PM-728 Conversion to CNC Teknic Drive Faults

Thanks Marty and Jim! The E-stop does reset the drive fault. The far left jumper was the only one I set to 'soft'. I changed the others to 'soft'. ooops! One other question: The wire from Acorn H1 IN5(Drive Ok Signal) to C86ACCP NC(Fault) or NO(Active)? 'Drive Ok Signal' active high or low? Not as m...

PM-728 Conversion to CNC Teknic Drive Faults
