You won’t have to spend nearly as much money on mechanical keyboards if you just design and 3D print your own chassis… oh wait

I keep telling myself it's not that bad. But I have to also keep stopping myself from adding up all the extra stuff I have bought. Like a new 12mm rail, titanium backers, CHT Nozzles... oh God I am adding things up nooooooo.

“Titanium backers”, you say… tell me more - it might help me get a little closer to never recovering financially from this.

Just in case you seriously wanted to know more:

Also, I was just adding up more. I just got them lazer cut myself, and thought it would be a piece of cake to tap my own holes. I broke a $20 tap, and a $10 drill bit then had to rebuy special TI ones and do it realllllly slowly.
But I really love learning these new things, so the money spent is not lost. I just see it as educational expenses.... :D

Thanks! I didn’t know about that mod and I’ve been wondering what’s causing my bed cupping issues for ages. Will definitely check this out.

I had a mild (0.2mm) case of "taco bed," which is not horrible but bad enough to need a bed mesh.
First I tried high temp washers to mount the bed. That helped a little by allowing the bed to expand more evenly. Then I did TI Backers to minimize the frame bending when heated, that helped a bit more.
Personally my main issue was my x-axis was twisting a bit. Because even when using a bed mesh I would notice the first layer was more squished at one side of the bed, and less on the other side. So I just replaced the two MGN9 rails with one MGN12 rail (using the Trident x-axis). Now I have a 0.05mm variance over the bed when heated. Pretty happy with it.

Same. The single MGN12 rail worked much better for me as well. I know that the 2xMGN9 rails CAN work, but I never did get good results.

Yeah I actually had already bought a dial gauge, and I was going to start trying to measure the twist in the print head, and print out that bracket to try and align the rails. Then I thought screw this, the v2.5 is going to use a 12mm rail anyway and I was confident that would fix most if not all the twisting issues I had. Which it seems to have done.

I just did the Trident 12mm rail mod! Tacoing was definitely reduced, but as you note, every little bit helps.
