There is an upcoming Chitubox version which seems to be more professional, but it is a pay version. I can`t say if there is anything included which fixes issues at printing, but there are repair tools included which are not available in the free versions.
Can`t say excatly what else is better cause i`m not using it, have you tried other`s like Lychee or Prusa?

The 'professional' upgrades won't help with actual slicing - they're limited to auto orientation, splitting/boolean operations, some repair tools, slightly different support styles, etc. https://www.chitubox.com/en/page/chitubox-vs Almost all the reviews I've seen suggest it's not really worth it (particularly if you have access to the original CAD data and aren't just downloading stuff on-line).

So this is the type of problem I have been having. The lighter grey part was printed on a 250K machine at my work and the darker grey part was printed on my Mono-X machine. Both from the same file. You can see the wave in the part printed on the Mono-X and this is after three or four different attempts that included changing the angle of the part and different support matrix etc. No matter what I do I get this wave. Depending on how the part is positioned when it is grown the wave will change position on the part but the wave is always there.

Not really sure what is going on with the Anycubic machine. I have had great luck printing batches of small parts on it but when I try and print larger parts in fewer number at a single time I always seem to get this little wave in the parts somewhere. It is very frustrating!!!

How does it look in your slicer with your supports on?
Maybe more supports needed?
Hard to say from the pics.

But comparing a 250k printer with a less than 1k printer is not fair.

I would support that 100%!

Without pictures of the slicing it is really hard to tell where the problem may be. There can really be many reasons...

Is this what you are asking for when you say pictures of the slicing??

I would go with more/heavier supports with more cross-links between them - I always like to anchor with a bunch of heavy supports for rigidity, then fill in with mediums to support the undersides. It looks to me like it's deforming as it increases surface area. Potentially, you could even add some sacrificial tabs on the part, to increase the area supports can/will attach.

Could also be a calibration issue, if you're overcuring the resin layers it will increase adhesion on the FEP. Have you done a RERF/other exposure test to dial in your exposure times?

It might also be worth tuning your lift/retraction settings. If the build platform lifts too high, too fast, it will tend to deform the print. Slowing your lift speeds could help, at the expense of longer print times.

Wow. This is more complicated than I thought.

Icon, did you say XJR-14? I'm in dude....

I would also go for more supports and some heavy from time to time.

Other solution could be to use an other angle for it. Find the right angle where you need less supports. It's always a try and error thing till you find a solution.
I would lift the left side a bit more up.

Lift up on the left side I think so too and then you may not need any further support on this site. But of course you have to keep an eye on the right side (it is not 100% visible to us)!
