On going chinese 6040 problems

Wait, give this a go first, if the velocity / accel in Mach3 is set too high the motor will stall, put the setting back to 2, fit the motor to the machine and reduce the velocity and acceleration until you get good torque.
Even though you reduced the velocity it could well be faster than previous.


Here's a quote from another forum;

"The other day I did switch from 1/10th step to 1/2 step. Seems to operate about the same overall - only MUCH faster. That first rapid move at 180 ipm was a bit shocking. I ended up at 108 ipm - the motors quit stalling then. Probably had to do with the 20 tpi lead screws. The mill runs great! I was slotting ).050" deep with a 3/16 end mill in aluminum at at 18 ipm and the machine seemed happy as can be. And a 0.015" climb cut finish pass left an awesome surface finish. Fun stuff!"
