Keith, I have a Vectrax 10x50 mill to which I added a Route66 4-Axis kit, and a Babin Machine rebuilt and CNC'd Hardinge HLV in my lab at the university. I'm currently working on rebuilding and CNC'ing a Hardinge TFB for home. I'll be painting it in another couple of weeks and I post some pictures o...

If you are running only the Centroid software on your controller PC (as recommended) there are some further optimizations you can do to the PC beyond the Windows 10/Centroid Configuration video . The Windows operating system runs a lot of additional programs called Services in the background. These ...

Look into Fenner Trantorque couplings instead of keyways and setscrews to lock your pulleys onto the shafts. Setscrews loosen and keyways develop slop leading to backlash. Trantorque couplings will not slip and will stay backlash free. Your local bearing supply house should carry them and you can ge...

Dean, Newark has a screw terminal 12,000uF@350V cap in stock that might work: http://www.newark.com/nichicon/lnc2v123mseh/aluminum-electrolytic-capacitor/dp/27T9721?categoryId=800000005280&searchView=table&iscrfnonsku=false I can't get to my cap to easily measure the to easily measure the te...

Pages 9 and 11 of the Oak manual shows Analog I/O being referenced to Analog Ground, however the Axis Headers do not have a Analog Ground pin. So, where to I reference the Axis Header signals Analog In and Analog Request? Do I use +24V Return or +5V Return? In appendix C, the Yaskawa Sigma V cable s...

I just wanted to confirm and document that using the Oak AXIS3/4 as encoder inputs pulling 5V power from the PLCADD connectors works without issue. The PLCADD connector housings are JST #PADP-12V-1-S and the crimp terminals are JST #SPH-001T-P0.5L, and the AXIS connector housings are JST #PUDP-30V-S...

CNCSNW, I don't know why I didn't notice that. I had originally intended to hook it up in velocity mode and noticed the microflex drive had multiple modes and I remember seeing the Oak board had multiple modes, just didn't bother to check if the multiple modes matched. Sorry for wasting your time. I...

I have two ABB Microflex drives and motors that I will be connecting to an Oak controller on a small Hardinge lathe. The Microflex can run in positioning (step/dir) , torque/current (0-10V), or velocity (0-10V) modes. Which mode will give me the better results? Will it make a difference if in the fu...

Thanks, Keith. Can't wait to see the new Centroid DIY website. My Oak board should be here soon and I'm looking forward to jumping in.

CNCSNW, I was thinking of using the PLCADD connectors for picking up +5V, not for using them for the intended purpose of adding an expansion board I'll just figure out the mating connector when my OAK board arrives. I did not realize I could use the MPG encoder inputs. Would you mind sharing your OA...
