Im having an issue where my dual z motors move at different speeds after an upgrade to 1.21.
its on a wanhao di3 printer.
It homes x and y correctly, and was working until i upgraded. also another issue i have is that when a print would complete (back when it worked) the exruder would go in reverse for about 10 mins and i had to hard power it down.. not sure what thats about either. i do i have a duet wifi for my delta as well and no issues.
