Oh, yes, got it! Thank You!!! There was one motor position value (I guess that is the same motor.n.pos-cmd pin You mentioned) that does not reset after homing. In that case solving it in HAL seems a lot more complicated than I thought. Thanks for the tip about sum and offset components, I will try to figure something out! > For the machine as you have it, and if you are happy that the stepper > limits are set conservatively, I would loop the axis feedbacks > straight back to themselves, they are only going to cause trouble. What I did with those feedbacks is for this special case: Synchronization is enabled, U pos-cmd is not routed to any stepgen or motor. So in this case, if any U command is accidentally issued in code or by jogging, operator will receive following error as pos-cmd will differ from pos-fb. If that mistake is in code, it will interrupt operation and ruin part as tool will burn marks in it. So to keep machine working I wanted to make sure that pos-cmd and pos-fb pins are the same. > > Do you need all 4 operating modes? ie: > XY controls motors 0 and 1 > XY controls motors 2 and 3 > XY controls motors 0, 1, 2, and 3 > XYUV controls motors 0, 1, 2, 3? I need last 2 modes, because both spindles (all 4 motors) are used in all cases: XY controls motors 0, 1, 2 and 3 XYUV controls motors 0, 1, 2 and 3 Viesturs ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
