I am totally putting the cart before the horse here. I realize that.
Question: Can you use the ‘C’ Z Core with the ‘J’ Core Clamps? I.e. Can you run a ¾" z axis on 24.5mm X and Y Rails?
Alternately: Are there any performance tests, forum threads, anecdata on the performance of ¾ EMT vs 1" DOM for a 24"x24" machine?
Background: I started slowly printing the ‘C’ parts almost exactly a year ago. I opted for EMT because with rounds of lockdowns, I was worried that I wouldn’t be able to get my hands on 1" DOM tube. I planned to have the build done by the new year, but i didn’t, and then just after New Years my family grew, then schools shut down, work schedules got weird, summer hit, i found a dollar, and I’m just now getting around to printing the last four parts (the lower belt retainers). I’ve sourced all of my hardware and am waiting on some steppers in the mail.
The thing is, I printed the C Z core very early on and it is a thing of beauty. It took 3 days, and I had to print it at least twice because of late stage print failures.
Now, 1" DOM seems a lot easier to get a hold of. I also am already anticipating wanting a larger build area and a stiffer frame but good lord almighty i do not have the stomach to re-print that z core. So, my question is, is there a world where a ‘C’ Z axis fits on a ‘J’ X and Y? I think I’m just trying to either psychologically prepare myself for starting my mk II just as I am beginning to assemble my mk I.
