It is the NEMA 23. Available on Amazon and other places. https://www.amazon.com/dp/B00PNEPW4C?ref=ppx_pop_mob_ap_shareNice work. Are you using NEMA 34 Stepper Motors? What is the torque on those?
I agree. I am running into a lot of vibration on face cuts but am sure I will get it figured out.I’m working on a home built CNC mill, rigidity is difficult to achieve with fabricated structures.
Thanks for the suggestion. I can definitely shorten it up and tuck it in. But it doesn’t even shake when it is cutting (I get vibration on facing elsewhere but the tool post seems calm) but if it will make it better I can definitely shorten it. Any other design changes I should look at? Thank you very much.I can see at least one place where the design looks iffy, for example, hanging the toolpost way out on a limb like that will almost certainly cause chatter and problems with repeatability, possibly even broken tools and bent slides. You really want to tuck that in more if possible
Rigidity is key with machine tools, and that usually requires mass and compact structure

So I have done some additional testing and I can confidently state I am getting a fair amount of runout. But I don’t think it is from the pillow blocks. I am pretty sure my backplate and mounting is giving me the most runout and I need to machine this a little more. Is there a bearing system you could steer me to that would be better than the pillow blocks?Nice, are you getting a lot of runout from the pillow block headstock?
