Tkinter Checkbox

[niro_one]

Hello ultimately this GUI will wrap arcs onto cylinders. Continuous linear+rotary. I have the math done (requires touch improvement). Cannot get check button to position properly. PSN_01 ideally below TBE_DIA. When complete ten positions total. Logic is if PSN_01 checked calculate DRL (drill start) + check button on centre or off centre. RGH (rough with endmill if DRL does not complete. FIN (finish with endmill because continuous linear+rotary output is normal to wrap diameter). Features are perpendicular to rotary. Appreciate any help. Cheers.

btn_01.place(x=15,y=60)

logic example:

cb_val= chk_v01.get()
if cb_val == 1:
    #do something
else:
    #do the other thing or skip the else
