At least 0.5 mm accuracy? This hot wire Maschine make 0,5% tolerance. not very precise. If You want precision, so you should take a linear rails Maschine.
All dimensions are variable within wide limits, but the left side must agree with the right side. It is also important that the motors are raised to the same height (water level) and that the worktop is also aligned horizontally. And the work bench must be in water Level. Motors can be everywere and the fishing line walk through angle Points. Those points must be accurate left and right. Calibration make the rest.
Small axes bringing more accuracy. I made it from alu tubes. Copper, steel or carbon tube can be lower Diameter -> better.
My 1 meter bow weights appr. 350 grams
