@陆 very nice. Thank you.

@陆 for some reason links in the community don't work on my phone (android) and I checked, play store doesn't show the update.

@De-Anna-Williams I was doing the same. I have been getting pretty consistent quality. My guess is your slicer settings need optimization. I have been using octoprint for transfer most recently. Prior I was using the same method as you. No problem.
You can get some of the settings from wiibuilder2 and transfer them.
I expect some updates soon that includes optimum settings for tina2plus.

@apple_user_1766773566 tpu is tricky to get good results. Temperature, speed ( slow it down) and retraction ( add a little) are crucial. Difficulty is compounded by the remote extruder.
Tpu is flexible and compresses. It is also very fluid.
Settings will depend on these factors.
There is no exact setting for all tpu, each is different.
Tpu melts hotter than pla, more like petg. It will require more retraction than solid filament due to compression.
Trial and error.

@Dale-Merrigan you can use kiri:moto to slice online, it also can be installed from google play store(not sure about app store for i phone). make sure you use the right machine in settings. then use poloprint cloud to upload it to your printer

@parwrench to clarify. be mindful of what bolts go where on the new one.

@printer-14 pretty much. It bolts to the stepper. They are a standard size 31mm center of bolt. providing the same nema, which on a tina2plus it is.

@Tina-j did you reformat the card on a pc? will the pc even see it? them things go bad alot

@printer-14 i have a tina2plus. i replaced my extruder mechanism with one from and ender3v2 i had laying around. works sound for me. after that yes the connector is replaceable .

@Natedawg a 1 kg roll holder isn't exactly a simple deal. Due to size and the arrangement of things the machine needs raised off the table to clear the extruder drive. Anything else compromises feed alignment.
You can read some of the other posts about where to get files from the Internet to print. There's several standalone roller type filament holders I think thingaverse has one specific to be printed on tina2 due to size of the build plate
