`go_position_ready` goes to drawing position

[HanBnrd]

Steps to reproduce:

from modules.drawXarm import DrawXarm
import config

port = config.xarm1_port
drawbot = DrawXarm(port)

drawbot.go_position_ready()

Expected result:
Goes to ready position

Actual result:
Goes to draw position

task: define all ready and draw positions for xarm

Hi Craig, the positions are already defined, I think it just requires to fix the methods. I will make a PR for it.
