Air-cutting imaginary OX plates from .gcode file from @Brandon_Satterfield now. And from another discussion…
I know that sometimes when people use steppers in a heated enclosure for 3D printing ABS and similar plastics, they damage the steppers. But I’m familiar with how how the 1A or so steppers on my printers get.
I’m running MT-2303HS280AW for all four steppers. Temperature ratings:
| Ambient Temperature | -20°C~+50°C |
| Temperature Rise | 80°C Max.(2 phase on) |
That seems to say they are rated to 130⁰C which seems hotter than I want to experiment with. So far, the X and Y steppers are just under 100⁰F and Z, which I set a little higher on current (not measured, of course 
) is 120⁰F, so probably there’s some headroom here at 1/16 microstepping. So @Brandon_Satterfield, did you run these 2.8A steppers at 4A with 1/16 microstepping?
