Very curious how you found the Chimera, don’t see many people using them and I have always wondered how they go. I have heard levelling them can be tricky, though looks like from your pictures you have a mic6 sheet or something for your bed which I guess isn’t going to flex and give different heights at different nozzles.

I'm using a G10 type black PCB board. It flexes a little if I have to pop off something stubborn, but usually they come off easily once cooled below 50C. Otherwise it is smooth. Before that I used Robax glass. They are manufactured smooth to a few microns, but it now conflicts with my infrared light based bed leveler.

The Chimera works well. It is small and the distance between the nozzles are well defined, so if you end up replacing it, the new one will be close to the same. I also wanted something that uses distinct nozzles, but if it ends up unworkable, I can still go back to a single nozzle.

Leveling is easier than the original E3D V6 because the throat part is smooth walled and not threaded, so you can play around with the hight after the whole part is fully assembled and is in the printer. Another advantage is that there are cheap replicas available that might have a few wholes place differently, but nothing that can't be fixed with a drill and a tapper.

I use a differential infrared adapter. Search for it in google. There are a few kits that you can buy but usually they are not as ready to go as BLTouch... So where do you want the sensor? It has to go to one of the sides. Close to the vertical axis so you don't loose printable area. Do you use both X axis limit switches?

Hi, nice design !
You write that you use a sensor mounted on the cooler fan, what adapter do you use ? I would like to use a BLTouch with your design.
Thanks.

Hello,
Thanks for your message. I also made a adjustable BLTouch version of your support, I did not yet published on thingiverse, but I will.
Regards.

Thanks. Looks great. How is the carbon-fiber X axis working for you? It was flexing too much for me as the PTFE tube was pulling it differently on different part of the build plate so I replaced it with steel ... but I do want to go back to carbon-fiber at one point.

Hi, in the end I also switched back to Steel, there were also too much flex with the carbon shafts. I chose 10mm steel tubes.

I’m running carbon on my x-axis and haven’t seen many issues but my PTFE is also way too long and was meaning to shorten it, perhaps I better leave a little more slack in based on what you are saying. My Hypercube isn’t my primary printer either, so only done limited printing on it so if I fill up more of the build area I might face a similar issue to you. My biggest issue with the carbon was the same as tech2c in that they needed a little careful rework to run smooth enough.

My hypercube is not finished yet, I still have to do all the wiring and tests, but I fear I have the same problem as yours, I find there is too much flex on the carbon shafts. I wanted carbon shafts to have the lightest possible carriage, I cross fingers.
