My forum addiction started with attempts to get answers to the types of questions you guys are now asking and addressing. I found it surprising that very little information was available on machine rigidity and cutting force ability. Stepcraft seemed unique in that they formerly provided “Torsional stiffness” specs. ShopBot also apparently uncharacteristically, provided cutting force specs for one of their products (to help sell its closed loop stepper option?)
IMO you guys are doing “Gods work” with your endeavors - thank you!
