Hello all, I am looking for your thoughts or advice. I purchased the 4hp in November of last year. Avid responded very quickly after I sent documentation of the problem, here is part of the response: Hello Brian, Thank you for your patience. I spoke with the team and we were able to find a 4 HP sp…

I used a new collet from avid and for the test I used a .25 pin from a precision pin gage set and a .0005 DTI dial test indicator reading was taken .5 down from the collet and in the mouth of the taper on the spindle

Bryan have you tried to check the runout of the inside taper of the spindle? If the taper is not machined on center it may cause the problem of if the taper is flat on one spot. Just a thought.

Yes I did mike, I posted a link to the videos I sent to avid I used a .0005 DTI and a precision pin and compared it to the other machine which was dead nuts. How did your build turn out?

Build is complete, squared and trammed this weekend. I need ot get dust collection set up and spoilboard. I looked at the videos you posted, do you get the same runout on the bad spindle in the bore? I coud not tell from the video, looked like it did not repeat the same runout on the bore, if thi…

Nice detail in your product! I know that took some time to get down. So you are past being referred to as a “noob.” :rofl: I have to ask, did you mess with your max acceleration in the configuration any or are you just setting your speeds and feeds correctly?

the runout at the taper was .004 slightly less than with the pin in the collet which I would have expected. I’ve got a new one coming, but it spins smooth no grinding or unusual noise. I think it would be ok for slab flattening not so much for 3d work.

Thanks for graduating me up to “noob +1” status… lol I run the Avid profile with ESS 278 to allow for some laser features. So no Accel changes. I set my tools to run at 100 ipm 12k-18k rpm depending on bit size.

Have you been able to compare the inside of the spindle shaft and the outside of it with no nut on? Just curious what those results look like.
