I made my own cables between the Oak and Delta ASD-A2 drives. Some pictures are in my latest addition to this post. I used the wiring diagram shown at the end of the Oak installation manual as shown below. Capture.JPG I made two changes. I did not link delta pins 9 and 10 (DI 1 and DI 2). I just con...

Time for another installment... I have battled and cannot seem to get rid of the oscillation while machining parts. So, I made a snap decision to replace the motor drives, and by extension the motors. Like I always do, I underestimated how long it would take but the job is almost done now. Fitting t...

i've done several delta oak installs, i like them, simple to tune and configure and they have load meter feedback for CNC12 to display. Cool, I did miss the load meter not working. Especially on my little machine! The current monitor output of the DYN4 could bee used as a sort of load meter. I used...

great, where did you end up buying them? info to follow.. https://www.centroidcnc.com/dealersupport/tech_bulletins/uploads/264.pdf https://www.centroidcnc.com/dealersupport/schematics/uploads/s14845.r1.pdf Thanks, I hadn't seen those documents and would have just worked it out! I got them from Alib...

ASD-A2 motors and drives are on the way...

Cool, thanks.

rigid couplings are a big no no. use typical cnc couplings like these. https://us.misumi-ec.com/vona2/detail/221302600297/?HissuCode=EKL/60/B/12.7/12.7&gclid=Cj0KCQjwjN-SBhCkARIsACsrBz5TuE7kgMLz23NamMpIh9Ui7Pu2EcNfh_-9iW4_QS-JM0iUNcLWvYMaAhJYEALw_wcB or china version https://www.amazon.com/Flex...

maybe from alibaba? https://www.alibaba.com/product-detail/Genuine-Delta-AC-Servo-Drive-ASDA_62378205644.html?spm=a2700.galleryofferlist.normal_offer.d_title.1ce07af2iWqkvU I don't know much about Delta drives, but them seem to be recommended in many places. My spindle drive is delta and it is awes...

sorry for your frustration, score some Deltas (Delta's are lovely with a 10 minute tuning job with Oak) and return those DMM's to DMM. DMM have offered a refund. I just don't know if I have the time and patience to upgrade to delta drives. Plus I can't find anywhere to buy them that is not really e...

Did you resolve your issues, could you share cure? Thanks Bob I did find the root cause of the issue. The problem is the DYN4 servo drives. They overshoot slightly and oscillate. They cannot be tuned to remove this. To be better the gains need to be so high that they lose control on rapid moves. DM...
