X crash on wipe tower
I have just upgraded my MK3S to S+ and my MMU2 to MMU3. I have hardly used the MMU2 because it was extremely unreliable, hoping for improvement with MMU3.
My first test print was the two color sheep - changed extruders to 4+5, but otherwise left the original setup as is.
Halfway the printer stopped with an X crash. I have never seen this as I normally run the printer in stealth mode, seems I forgot to set this for this test print.
Anyway, when resuming I found the printer had stopped at the wipe tower, which was very bumpy and caused the nozzle to drag on some protrusions... which probably caused the crash detection to kick in. After continuing the print, there was a layer shift of about 1 mm in X to the right, so it was not a false alarm.
Apart from this crash, the print went through fine, with a total of 69 color changes.
Anyone has similar problems with the wipe tower?

RE: X crash on wipe tower
Hi, i see a messy wipe tower all the time and a few times mine has crashed then resumed. When there is a filament change i think the nozzle is too close and warps the wipe tower. When it tries to do it's usual thing it encounters this part again and can crash. I think i read somewhere it's supposed to change nozzle over the wipe tower but i would prefer to test a filament change elsewhere. Here's a photo of an example wipe tower. Tip: I tend to place mine as far away from the print a possible so strands of filament don't get pulled into my print.
I'm using a standard MMU3 and MK3S+ set up but with a revo nozzle. Not too sure if that has any impact but i suspect not.
