Good afternoon,
I started working on building a CoreXZ printer called Voron Switchwire.
This printer uses a counterweight (via a retractable keychain) to lift up the X assembly since the motors driving the CoreXZ system are not able to maintain the weight.
Although unrelated, I know that Duet has advanced features such as pressure advance.
To simplify the setup, I am thinking about using a stepper motor with integrated planetary gear reduction mechanism (5-to-1) and forgo the retractable keychain.
From the specs sheet, however, I see that these mechanisms come wikth a "less than 1 degree" backlash.
I do not understand how does this backlash could effect the movement of the axes.
I guess my question is two folds;
1st) Can duet make up for this backlash the same way it magically handles pressure advance?
2nd) If I used the 5:1 geared motors to drive the axes, what kind of an affect could they have on the prints with their less-than-1-degree-backlash specs?
I know many will say just build the the printer as specced but I was very excited to learn about the planetary gear system and I would love to have an actual understanding about these things.
Thank you for your time, I am looking forward to learning about this.
Cheers
P.S.
This is my first message on the Duet boards. I apologise in advance for any possible mistakes. I am posting this under General discussion. Please feel free to let me know or just move the thread to the appropriate board if it should belong elsewhere. Thanks again ![:) 🙂](https://forum.duet3d.com/assets/plugins/nodebb-plugin-emoji/emoji/android/1f642.png?v=nm8a6hvte64)
