Hey, i noticed you had a problem where the wave generator popped out on your smaller drives, this is because it does not have a shaft with a bearing the way you put it together. The flange you received with these ones normally holds a motor for direct drive and the bearing of the motor is used to keep the wave generator in :)
@@whyf16uy Get yourself a proper 3d printer :) helps a really long way! (Internals here are all printed from Polycarbonate Carbon fiber. (i actually have a second diy mount that can carry 5kg and is all 3d printed)
I like your philosophy about going to max size 😁 This is something I've always wanted to do, so it's great to see that it is possible to do without having a full machine shop. With regard to the guide curve - do you think it would be possible to smooth that out with some PEC stuff? You've most likely said it already but my memory is not so good - what software are you using in the controller and as the driver interface to the computer? And I really like the picture 😊
I'll look into the PEC stuff, definitely need to try a few things. I use OnStep with the MaxESP4 board and use NINA to control. If you look at some of the previous build videos I go into a lot more depth.
Those harmonic drives look like real monsters I wonder what load capacity your mount can take now? The old CGE pro I use has NEMA 17's & I've never had an issue with them slewing the RASA around & the dual rig I'm currently building, with it having 30KG of counterweights to balance it all it seems to handle it fine although the real test will be when I'm imaging with it. Congrats on your 1000 subs to clear skies
Well they should hold a lot.They are HUGE. I guess I'll have to look for a C14 🤣. And if I'm not mistaken you were my first subscriber, so I couldn't have done it without you.
Well I really have no clue what I'm doing but I just pulled them tight and held the motors while tightening them down. I tried to get just enough tension so they wouldn't slip but not enough to cause any lateral tension on the pulley's axel. If that makes any sense.
@tubedude54 alliexpress the link is in the description. Depending on the size of the drive determines the shaft size. I believe the 17's were 10mm. If you look at the schematics of the drives it shows you the diameter.

Very cool. That must be so satisfying to have the skills to do this
Haha I don't know if you'd call it skill. More like 8th grade shop class level. 😄
Very cool! I can't wait to see the focuser :)

Makes sense. My redneck solution seems to be working so far.
@@whyf16uy always good, i received my stain wave 17s today and am now designing everything in cad :) less redneck way
Sweet, I just don't have access to milling equipment or I'd try something better

Amazing work. Thanks for the link to the harmonic drives. I've been hesitant to buy as i didn't want to get the wrong thing.
Glad I could help!
Excellent video, thanks for sharing your work
Thanks for watching!

How did you tension your belts? I'm currently in the process of making my own harmonic mount but I'm just not sure how to tension them.
Well I really have no clue what I'm doing but I just pulled them tight and held the motors while tightening them down. I tried to get just enough tension so they wouldn't slip but not enough to cause any lateral tension on the pulley's axel. If that makes any sense.
@whyf16uy Ah ok, hard to tell in the video but how have you connected the pulley to the drive? Is there a shaft?
@Zegery yes I bought a 14mm stainless rod and just cut it to length. One of my original build videos probably shows it better
brilliant. clouds do suck.
Have you ever thought of building and selling your mount?
It's only worth it if you do it yourself
Did you get these on ebay also or if not where? Also the wave generator, does it come in different shaft sizes?
