oh, i am more than happy with the way it works, and am looking to do the router attachment here soon. i was just curious how far it has been pushed and was looking for a base line to start. it prints great, and i am working on the heat settings. i am going to mill the build area perfectly flat like we discussed to accommodate any possible un level areas from not being 100% on the legs. i do wonder if i plan to use this specifically for 3d printing, how tall i could safely go with the Z axis. since its moving slow and there is no torque from the extruder, rigidity shouldn’t be an issue.
