The benefits in my opinion are:
- Simpler design, easier to assemble.
- Less parts
- Easier to exchange, remove hot-end
- Better belt tensioning mechanism, just like y-axis.
- stiffer construction
I've been testing with this for 3 weeks now, without any problems. I sometimes had to slightly increase the tension of the tensioning mechanism.
Please give your critical opinion, you don't have to play nice
