I have the 48x30 Mark 2 and have been surfacing some slabs. Worked great until my router took a bit of a nose dive and cut too deep. Prior to this I noticed a bit of vibration or quiet growl from about 24-36" on the X axis. I chalked it up to the wood in that area (maple). The job will be fine BUT I have a 5mm machine screw that fell out just about the 24" mark and thats where the nose dive started. I jogged back over to surfaced area and verified my router is headed downhill on the X axis. A few little bumps and the cutters contact the surface (have clearance to start). The rail itself seems fine. I’m thinking it’s a gantry or lead screw issue, and the M5 screw is the key. Uploading a couple of pics. I am kind of to the point of reverse assembly. Going to watch some videos. Any ideas appreciated.
Hi @Ump98,
The screw is from the router mount.
Another issue I see is that the screw on the the anti-backlash block looks to be hitting the lead screw nut when raised all the way.
The limit switch will need adjustment to stop the Z gantry a bit lower for clearance.
Thank you so much! My eyes arent what they used to be, but that makes sense. I will take a look at your recommendations tomorrow. Lot to learn here.
CJM Sharp eyes. Thanks again. The screw on the backlash block was too loose. Not sure if I failed to toghten or it worked loose.
The threads on the M5 screw were damaged, so I replaced it. I need to replace the router and check travel and tram, but hoping this solves the problem.
That M5 screw could definitely be the culprit, especially if it’s causing some misalignment. If the router’s tilting, it might be affecting the X-axis. When I had a similar issue, tightening the screws on the lead screw assembly helped a lot, and checking for any play in the gantry made a huge difference too.
