I own a CNCEST 6040 since nov 2020. After a few days of research and configuring and tweaking the machine and PC, I have used it for four months now and I must say I am very satisfied with the results so far.

The only thing that I am concern with, is that the frame of the machine is crooked (not square). The gantry that rides on the Y axle (back and forward), has about 1/4 inch (6mm) difference from the left to the rigth side. When I bring the gantry all the way forward (Y-), the left side of the gantry frame touches the front of the table/bench first while the right side of the gantry is about 1/4 inch off. When I slide the gantry back (Y+), at about half way, the axle screw and/or the Y axle motor (not sure which exactly) starts making a clanking sound which gets louder as it travels back... That clanking noise has me a little worried. I think the motor is working a harder as the gantry travels back because of the table not being square

My question is: Does anyone know what should I do to eliminate this situation. I am afraid that if I do too much work on the backside of the workbench, something is going to break. Will appreciate any helpful comments. Thanks in advance!!

Welcome to the forum! Are you able to loosen the bolts for the bearings and reposition the gantry? Is there anything in a bind mechanically? Can you move the gantry by hand, and if so does it move smoothly or bind anywhere?

Honestly, I haven't tried anything yet. I wanted to get some pointers before starting to break into it. My first thought after studying the mechanics of it was to loosen bolts and try to reposition the gantry. I am able to move the gantry by turning the motor by hand. I did not noticed it binding but would have to check later. So, that will be my start point
