You wouldn't run a single piston internal combustion engine without a counterweight as it would shake itself apart. This is the theory behind adding a counterweight to my y-axis and now I have finally put it into practice. First I lightened my y-axis carriage and build plate by drilling lots of holes. I then added a set of linear rails and a tray to hold two lead counterweights to offset the 1850 grams of moving mass that makes up my y-axis. Note the 6x20mm steel bar attached to the bottom of the counterweight tray which is mainly for rigidity. I increased the stepper motor size to 1.8A with a 4.8kg.cm holding torque to cope with the additional weight. So far I am very pleased with the results and I have got my sorbathane feet back on and it is no longer wobbling around like a jelly. First print came out beautifully but early days yet...
