Hello all, very new to this forum. I've been building an mpcnc with the plans of putting a j tech 7 watt laser on it. I'm now thinking about scrapping that whole project and going with an ARCO system for the above stated laser diode. My question. I see 14 tooth pulleys are used on the nema 17 motors. I have 5 nema 17 motors and a slew of 20 tooth pulleys that handle 10mm gt2 belt. Is there a reason I can't use 20 tooth pulleys, or should I just go with the 14 tooth. I'm trying to figure out how to use what I have. Thanks in advance for the input. Dale Lawhorn
