ponar remo fwe 16 wobbly table y axis

Hey there,
i was wondering if you guys could help me with the table wooble i have. The x and z axis are smooth and solid without any play but the y axis has a gap of arround 0,8,mm on the solid dovetail ( not the side where the adjustable gib is). I tried tightening the adjustment screws of the gib but the wiggle only stops if i really turn them tight and then i am not able to move the table in y axis anymore. The Leadscrew and the nut are prefectly fine with minimal backlash. I disassembled the machine and cleaned the table. I also checked all the gibs for even contact with blue die. All the surfaces are still scraped without any real wear marks. For now i added a brass stripe with the thickness of 0,8mm into the gap and the table stopped to wobble completly but i am still curious if there s not another way to get that gap / play out of the machine table. Remachining would be an option but honestly for the things i am making and what the machine cost me that would be to much.

Here is a picture for better understanding

here is a picture of it before i cleaned it:

Normally the tightening gib should fix the problem with play on both sides of dovetail, but maybe if this machine worked a lot with large play matching surface could get waved so it won't work properly with direct contact.
Other possibility is that large wear of surfaces caused contact on non flat surfaces (on the edge of dove tail or on flat surface beneeth it) chamfering edges of matching surfaces could help then.

First of all thank you for the response the reason you state which could cause the table wiggle seems reasonable but after talking to the selller and also looking at the contact surfaces i highly doubt it was working hard or often in use. All the contact surfaces on the x, y, z axis still have factory scraping on them and i even checked the surfaces for even contact with blue dye. Could it be that the leadscrew is not perfectly in the middle or that the gib which is installed in the y axis was made once while a repair and it has the wrong dimension (to small)?

Btw if someone has the same maching as i do would you be able to send me the measurements of the gib from y axis i included a picture for better understanding.

This is the locking gib. It is used to keep Y axis in position and make machine more vibes resistant when U machine planes or grooves along X axis.
There can be another one on the other side for play reduction.

Even a small piece of debris or contamination in the dovetail or gib can cause wobbling. Ensure that all surfaces are completely cleanmapquest, and there's no debris that's preventing proper contact.

On all three axes (x, y, and z), the contact areas are still scratched from the factory. I used blue dye to make sure they were all in good touch.drift hunters

That brass shim solution actually makes sense as a practical fix, especially if the wobble is gone and the table still moves smoothly. If the dovetail itself has a consistent gap on the solid side, it may be more of a geometry or fit issue than just a gib adjustment problem. Tightening the gib will only help so much before it starts binding, which sounds exactly like what you’re experiencing.

I’d probably keep the shim in place for now, check that it doesn’t shift over time, and monitor wear after a few hours of use. Remachining would be the proper long-term fix, but for the kind of work you mentioned, it may not be worth the cost unless the accuracy becomes a real problem. Funny enough, this reminds me of how I choose practical fixes over full rebuilds in other fields too, like when comparing a quick repair versus calling a full Tree service Inverness team for something that only needs trimming.
