# Probe Basic ATC Simulator The stock atc_carousle subroutines are build around the pulse/index tool change, so the gray-code carousel configs are untested and left as examples Imperial and Metric version vmc_index_inch.ini vmc_index_metric.ini Metric Machine Size X 600mm Y 200mm Z 400mm Imperial Machine Size X 24" Y 8" Z 16" Both machines have the X and Y home in the center of travel. ## Original Vismach Readme This is a Vismach simulator config intended for testing out tool-changer configurations The Vismach model combined with the sim_vmc.hal file features three axes with home and limit switches, a carousel with both gray-code and pulse/index outputs, a locking bar and a power drawbar. There are two alternative configs, one demonstrating gray-code carousel coding and the other demonstrating pulse/index. Note that the carousel component also supports straight-binary and individual sensors. The "virtual" VMC is created by the sim_vmc.hal file and defines the following signals that my be used in the other HAL files Axis positions x-pos y-pos z-pos Axis limits x-pos-lim x-neg-lim y-pos-lim y-neg-llm z-pos-lim z-neg-lim Simulated Spindle spindle-cmd - set spindle speed in rpm, negative for reverse spindle-pos - the simulated spindle position (revs) spindle-vel - the simulated spindle speed out Toolchanger arm arm-act - actuate the arm arm-in - arm in limit switch arm-out - arm out limit switch Carousel lock car-lock - activate the lock car-locked car-unlocked - limit switches Drawbar tool-release tool-released tool-locked Carousel car-fwd rotate clockwise car-rev rotate anticlockwise bit0 bit1 bit2 bit3 bit4 - Gray-coded carousel position
