.....and another Heavy one!! :) 🇬🇧
Hey guys,
For those who've seen this post before, skip to the end: I'm starting a NEMA 23 upgrade! 😁👍
Technically, my CNC isn't new. I completed it a month or so ago and have been tinkering and trying to make it better and more rigid.





Profiles are 1000mm by 1000mm and I have 820mm by 790mm of workable surface.
Running off an Arduino Uno + CNC Shield + Raspberri Pi running CNC js, which I can run and send gcode to from any browser/device connected to my Wifi network.
I also made some changes to the router holder assembly to make it more rigid. Didn't have the original models, so made them from scratch in F360 using Thomas' printed models for reference.
Also changed the top of the gantry in order to get rid of the GT2 belt and run the Z-Axis lead screw directly off the Nema17. With the original design, my motor kept slightly budging forward under the pull of the belt. If anyone is interested, I can share the model. It's pretty much plug-and-play.
On to my question: I opted to use these collet extensions for the makita in order to get all the way down to my work surface without having to prop up my stocks when milling. However, I'm getting a LOT of oscillation and vibration due to the 1 1/2" length they're are adding. If I could get a 1" extension, that would probablty fix the issue. Problem is, I haven't been able to find one at all. It does seem that @Topsie is using a shorter one that could work for me. Could anyone direct me to it?
Cheers!

Yes, i was desapointed at beguining, but after i couldn't imagine without
I know right? It has a odd learning curve until everything just "clicks" and it becomes super intuitive.
Exactly that.........yet i don't know how to navigate in freecad without it
lol
