Yesterday, I was printing out a filament roll holder using mac pronterface + slic3r + sprinter 012855c + ramps 1.4.

Things were going great and I had printed the base and started printing the rectangular outline that would eventually have the places for the bearings. At one of the levels, the Y stage didn't move enough and it started printing in mid air. I think this might be due to the acceleration being too high in sprinter:
float max_feedrate[] = {200000, 200000, 240, 500000};
float homing_feedrate[] = {1500,1500,120};
For my Y axis, I bought one of the nice high torque motors from ultimachine so it should be fine, but I noticed that when it was going from side to side it would be really agressive in how fast it went. Have other people run into this? If I still have pronterface loaded, is there a way to start a print from where it left off a day later or is that just more annoying than it is worth?
Thanks!
