Comment on Kobra Max direct drive mod & insulation

Nice move! I think you have it correctly mounted though, I wouldn’t put it on a bracket. I used a conversion bracket for direct drive on my Max and I kept getting pulsing issues.

I think they were due to the filament pushing down the hotend slightly when starting to extrude because the hotend is mounted on the compliant strain gauge mount. With your method, it stays isolated and doesn’t push down more on the strain gauge mount when the extrusion starts.

Please give me an update if you can if you run into any other problems!

Btw, what is that conversion bracket called like? Where did you find it?

Hah, good to hear from you. I spent some hours yesterday designing a replacement print head housing where I could mount the Orbiter on top. While doing it it occurred to me that what you describe could actually be a problem. I have three options now:

Continue with my original idea but also attach the flange to the carriage in order to not have it dangle around while the X-axis moves.

Try to attach the Orbiter onto the mounting fork together with the hotend

Get rid of the whole strain gauge thing and use a modular mounting kit and add some other bed-leveling sensor.

What do you think?
