Bit tip:
Why spacing matters
Every extra 0.1 in between letters is material turned into chips, on every edge of every part. Too little, and the cutter clips the next letter. The safe minimum is the bit diameter plus a small clearance; going wider rarely helps.
Let NestSigns do it on your real file. Type the same bit size in NestSigns and it sets this spacing for you, nests the letters, then measures the smallest gap actually left before you cut. 20 free runs, no credit card.
