In my unit the hot-end fan (right side on the extruder) is horrible loud. All other fans (bottom and PSU) are bearable. The PSU fan gets noticable when PSU is loaded during heating but I could live with that. For testing I blocked the hot-end fan with a toothpick before switching on to hear the diff...

So, I gave it a try and can say: it is worth it. See details here https://www.thingiverse.com/thing:4825065 - a bit stringing is left on the lower temperatures (185°C). Also printing with flex material (https://www.thingiverse.com/thing:4824544) worked.

I call my A30M the string meister.

Haha, maybe this helps, should also work for A30M:

Ohhh that's what I was hoping but I am curious of the specs of those 2pin fan headers. I feel like Geeetech should have that info but I feel like it would be hard to get the answer. Cuz a 40mm fan might be something like 0.06amps, but the Pi might be about 1amp, so idk if that would be a good idea ...

Thanks, found it (https://www.thingiverse.com/thing:4737611). I'll give it a try. The weight of the bar lies on the lead screws, hope there is nothing to worry about vibration. Best test is to print same temperature tower gcode then and see whether stringing is reduced. Maybe usable print height is ...

Thanks for the response. I am not sure what you mean, but I think I just need to open the printer and look at the motherboard to understand. Unfortunately it seems there is multiple motherboards for this printer so I can't just look at a random pic lol Got it, opening the printer will help to under...

If I would do it I'd use something like https://www.amazon.com/dp/B08NJZL2WV buck converter with USB-A socket to supply the RPi with a usual USB cable. However soldering iron and an old fan cable is required .

This was also my thought to reduce stringing. After printing the PLA temperature tower (https://www.thingiverse.com/thing:2729076) for my PLA assortment it is obvious, that the ideal temperature is 215°C where stringing is nearly gone. It interestingly increases with higher and also lower temperatur...

Now that I received and tested my A30T it is clear that I want to make some changes and fixes in the firmware. The unit has the mainboard type M11 and displayboard S02. Unfortunately neither the Smartto-eclipse nor the Smartto-IAR repositories on github have advanced to A30T. I read out both firmwar...

This is just a longer cable for the 3DTouch bedlevel sensor.
