Quick tool Change Base V5 with Servo Mount

Remix of ProperPrintings Tool Change setup, https://www.thingiverse.com/thing:3369444 X and Y Probe Offsets should be the same as mine. Of course it might be with the Z-offset, but my setting should be close: X is -50.0 Y is +20 Z is -5.77 I Made a change to accommodate a 9 gram servo for Auto Bed Levelling. The arm is included. I used the Z-Stop probe switch. I removed it from the board it was soldered to. I removed the metal tab from the switch. I used the screws that hold it to the board to mount it to the arm. The arm is made from 2 parts, https://www.thingiverse.com/thing:3664819 from Karip for the servo end of the arm, and the lower end from https://www.thingiverse.com/thing:3293821 by terenceang. It left a small area to bend the pins down of the endstop switch after soldering the wires to it. To use the servo probe on the Creality 4.2.2 or 4.2.7 boards I used the description from terenceang's "Under $10 DIY Auto Bed leveling Z-Probe for Creality Ender 3", and realized the changes with the newer boards. here are those changes: On the Ender 3 Pro with 4.2.2 or 4.2.7 board, you use the 5 pin plug on the board to hook the servo to, black servo wire (-) to G, Red (+) to V, and the orange servo wire to In, and the tactile button is attached to the z stop plug, not the 5 pin port for bltouch or whatever ABL probe you are using. Thats Servo 0 port on those boards. To set the angles in a terminal with GCODE, make sure you enable M281 in the configuration.h file. its the last line for the Ender 3 in the file. then you can play with angle with M280 P0 S90, where S90 is the angle, to find the deploy and stow angles you like, then set them with M281 P0 L55 for lower or deploy, and M281 P0 U155 for stow angle, changing the 55 and 155 to what you need. for the steps provided, step 2 changes are Z_ENDSTOP_SERVO_NR is now Z_PROBE_SERVO, step 3 is now NOZZLE_TO_PROBE_OFFSET and set the 3 numbers in the brackets for x, y and z. Step 4 isnt needed at all with MArlin 2.0 and the 32 bit boards, you just use the 3 pins on the 5 port probe port. Also, remember to fire M211 S0 so you can set the z axis lower than 0 to do your normal z offset like you would with ezabl or bltouch. it seems to work quite well for me so far.
