Drecreased max temp for stock hotend Lowered default acceleration.

Elehiggle commented 6 years ago

Any particular reason to decrease the acceleration? The new Anycubic official open source Marlin at https://github.com/ANYCUBIC-3D/I3-MEGA still has those 3000 values. I must say I ran into resonance issues due to too fast speeds and this will probably help a bit, but I thought I had to generally decrease the speed.

To high acceleration causes the mainly stress to belts and stepper drivers but it is also responsible effect you ran into. The stock printer is not made for that.

Guex commented 6 years ago

i disagree to lower HEATER_0_MAXTEMP to from 285 to 245, as it will turn off the heating way too early. The default firmware allows to heat up to 260 and i have ABS filament with vendor recommendation to print @250. i'd recommend to change it back to 285 like ANYCUBIC had.

derhopp commented 6 years ago

As long as you use the stock printer I do not recommend these high temperatures because of the PTFE insert in the hotend. They start to deform at 250°C. Thus, if someone wants to print with higher temperatures, it is better to raise it intentionally. Just my opinion.

Agree with @derhopp, you can build it with own configuration (as I did).

BTW: I like this repo, but what was a reason for disable issues? Issues are good place for negotiations.

derhopp commented 6 years ago

I didn't disable issues intentionally. (: They are now enabled.
