i am eric from china. cnc router maker. i am glad to see you chose our chinese machine. here i can see a good review for now to our chinese cnc router. i am very glad to know it. as some customers dont trust our chinese machines. of course, it depends on which company you choose. there really huge quantity companies in china. and it is not easy to find the best one. i just registered this forum because i think i can get more information about feedback or review on cnc router. i like to design cnc machines and keep improvement. for a seller. i am always entangled to make cheaper machine or keep high quality ones. as some customer like cheap . but after few years selling and service after sales. i have one important idea. for one machine, the most important thing is the customers feeling of using . of course. it mostly depends on the controller. like you say mach3 are starting to become common. but for some customers, mach3 is complicated to use. and they also want to use it. maybe after few days using. they can learned. haha. i really hope there is only one controller system. so we dont need to be entangled about which control system should we sell . maybe customers have same idea as me. haha.
