GF replaced my Basic unit due to a loud vibration that it developed. Other than that vibration, it was perfect. I am now concerned that maybe I should have just sucked it up and lived with the noise, as I see some concerning things in the replacement unit.
Last night I was experimenting with the correct kerf for a box design, and I noticed that the box tabs fit together differently depending on whether the tab was cut on the X or on the Y axis. I saw this thread describing a similar problem caused by the frame not being square.
One of the troubleshooting steps in that thread involved checking how the belt was riding in the pulley. Well, I went looking, and I noticed that the rear right pulley, on the Y axis, looks totally different than that in the rear left. It sticks much farther out away and looks like it’s about to come loose, although I don’t think that’s the case. Could someone take a look at the photos and let me know if this is normal? I am 100% positive that my previous GF was not this way.
Also, what is the expected range of variation in cutting dimension? I cut some squares in different corners of a sheet of acrylic, and I notice there is about a 0.007" variation in size from one corner to the other. Since this is more than the kerf is typically in this material, and the GF specs page says 0.001", this seems wrong. But it would be good to get some confirmation.
