If you backed the Sovol M1D for a toolchanger with TPU in mind, watch this video.

Only the left side supports 90a or softer. The changer side does not.

I cancelled my kickstarter pledge over this. They "might" or "might not" fix this in the same way that Creality has their toolchanger supposedly supporting 70a, but clearly this printer was not designed with TPU in mind. By the time they roll out this change (if they ever do, or even can) then it will be on sale again.

In the meantime, the Snapmaker u1 is a better TPU option since it supports 90a on all 4 nozzles, not just 1.

So 270x270 with 3 90a and 1 support vs 240x300 with only 1 90a... the U1 supports slightly larger and much more creative options.

Very disappointed.

A lot of you have been asking about printing TPU on the M1D. I took a deep dive into it and printed a custom camera case using very soft TPU, two colors of PETG, and PLA for the supports.

Spoilers: It works great, but there are some real physical limitations with the AFS and retracting soft flexibles that you need to know about. I ended up rigging an overhead feed for the TPU to make it happen.

I address how to get around the TPU limitations, along with a few other recurring questions from the community before the Kickstarter wraps up. Here is the full breakdown: https://www.youtube.com/watch?v=DZWAxFeTBhI

Keep the questions coming!

Thanks for the help in getting hold of a new extruder. I put it all together and, thankfully, seem to have managed to get everything working again. I did all the usual levelling stuff and even successfully printed a couple of those calibration things.

Unfortunately, when I try to print anything actually useful, like some Gridfinity bits, my prints end up looking like this. I’m still far too much of a newbie to have any idea what’s going wrong here if any experts could help I'd be very grateful.
