In our setup, Mach3 sends pulses to the a servo driver which moves each servo while monitoring the axis' reported movement via direct feedback from the rotary encoder, at a resolution of 128ppr (x4 = 512). <ref>https://forum.protospace.ca/t/cnc-router-acting-funny/243/29</ref> That part of the system is “closed loop”. | In our setup, Mach3 sends pulses to the a servo driver which moves each servo while monitoring the axis' reported movement via direct feedback from the rotary encoder, at a resolution of 128ppr (x4 = 512). <ref>https://forum.protospace.ca/t/cnc-router-acting-funny/243/29</ref> That part of the system is “closed loop”. | ||
However, Mach3 doesn’t know if the servo kept up or not and if the machine is in the expected position. The servo driver knows if it went as far as it was commanded, but if the discrepancy gets too large, all it can do is raise an error signal or shut down the driver. When this happens either due to an error or an e-Stop, the machine | However, Mach3 doesn’t know if the servo kept up or not and if the machine is in the expected position.

When this happens either due to an error or an e-Stop, the "machine" no longer knows where it is and must be rehomed (Ref All) to the limit switches. | ||
