Struggling getting full use of printed area (A350)

Hello top all - I’m sure this is not a first - or last time a topic like this has arisen.
Looking for suggestions

When trying to print using the full table area, I get issues along the front and back areas.
I have been using this printer for several years and still retain all original parts.
I do have a table wiggle moving forward and back, which is probably why I have my issue. Not sure my uploaded picture made it, but it shows my issue.


Suggestions? Thoughts? Ideas?
I really like the printer and use it to print larger models than their original size, so really need to get full use out of my table.
Thanks to all!

Presuming you have recently done bed levelling, if you have “table wiggle” then that is almost certainly the problem. Mine was so bad you could see the back edge rise and drop during changing of direction of movement.
First ‘solution’ is to check the slack and/or adjust the linear modules as detailed on this site. Second solution is to remedy the design failure and fit linear guide rails as you might see in several photos here.

Just recently had this same discussion with another user. Here is the link to what I told them; the same applies for you.

Would the new bracing kit help with this bed movement issue?

Another possible issue is heat bed temps at the edges, it can be a full 10c lower along that edge line.

Yes, possibly, as stated in the conversation I linked to, but it may depend on how bad the wobble is.

I never took the time to monitor, measure, and confirm but I was never successful, or rarely successful, printing at the .08 or “fine” precision level. I assumed it was an accuracy issue allowing the hot end to get too close or run into the previous layer. I am convinced I was suffering the wobble. I have the bracing now but haven’t attempted .08 or “fine” since installing. I will check it out, thanks!

What have you done so far to improve?

Did you heated leveling (let it sit for at least 30mins)?
Ever tried manual leveling?
