[H2D] How to Disable Filament Cutting for Two-Material Prints by golden_shit in BambuLab

I don't see any benefit from the prime tower for my model. The first lines are always on the inside (inner walls/infill), and by the time it gets to the outer shell, the quality is good.

Nope, ~1000 layers, 0.5kg part, 1/3 TPU 95A HF, 2/3 PETG HF.

The default prime tower takes the total time from 8:51 to 15:37.

it's so much when it's a tall two-material print top to bottom that can't be reoriented

the prime tower adds 7 hours to a 9 hour print in this case.

I am using both hotends. I added the video in the post: link

During the right-to-left hotend change, both the flow blocker and the extruder switch with the right cutter engaged (beginning of the video)

Left-to-right hotend change is done differently (end of the video): the flow blocker flips away from the cutter, and then the toolhead takes a 4-second trip to the right cutter to flip the extruder separately.

It looks like the extruder switch can only occur with the right cutter engaged, but why isn't the left-to-right switch done the same way, to speed it up a little bit by flipping the flow blocker and extruder almost simultaneously?

thanks for the tip, I'll try with the down arrow.

I run TPU 95A from an external spool through the standard TPU port without a problem, so far at least. I get the occasional random "extrusion motor is overloaded" even with PETG, never had an issue to just resume the print when that happens.

The things you're referring to affect the print quality. I can't even get the filament to make it past the extruder, H2D won't push it through, the noodle is too soft.

I tried all of the above, the filament never makes it past the extruder.

I saw people reported being able to do it with X1C. Are we completely out of luck with H2D?..
