Hey guys, last year I went to a guys house whose ad I found on Craigslist for cutting CNC parts. I had him cut some complicated shapes which I was happy about, but on my drive back I pulled over on the side of the highway and started researching. Yup, that day I won a gecko g540 on ebay! Talk about diving in.
I have wood working experience but not metal, I hope to someday. 8020 was a natural choice for me. Or so I thought, for what I spent a reputable welding shop would have gladly done this and it would be stiffer.
I think my big problem is that I didn't spend enough time researching really. haha tends to be my issue. I found a design I knew I could build to get my feet wet. Here is what I was going for:
Attachment 386264
Here is where I am today, I'm finally playing with two axis. There is my question. What do I put into mach3 for the 1605 chinese screws for microsteps. I left mach 3 in mm. I can't seem to figure this out. I'm extremely proud of this mockup.
I'm using gecko g540, mach3, wantai 200step motor, 1605 screws (which i think means diameter 16mm and the pitch is 5mm)

I'm starting to realize the errors in my design where I will lose stiffness, but I think i will be able to use this machine to make itself stiffer.
Honestly, any input is welcome!
