Extending MK3s Max Practical Print Weight

 

Hello all,

I recently started a print on my MK3s that's going to end up being pretty heavy (900 grams). Coming to this realization, I did some poking around and found this thread that suggest the max practical print is less than 500 grams or so. This limitation is dictated by y-axis accelerations vs mass of the print and hotbed.

My question is, if I cut my print speed in half (via the tuning menu) would that be enough to prevent issues? 

The good old kinetic energy equation (KE = 0.5 * mass * velocity^2) suggest you can push 4x mass at half the velocity, so I think there's hope. I'm hoping someone else has some experience with heavy prints and can give some pointers.

Haven't done the math, but you can also adjust acceleration and jerk settings independent of speeds. Speeding up or slowing down gradually will help a lot with quality.
