Benefits of Reduction Gearing? Would reducing the X and Y axis by 2:1 and dropping from 1/16 micro step to 1/8 micro step have any advantage? I would imagine that you would have more achievable accuracy at 1/8th step due to having more torque and you would still be able to drive at "1/16" step. The question I really have is would this be negligible? https://reprap.org/forum/read.php?14,771432,771432#msg-771432 Tue, 08 Sep 2026 17:55:02 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?14,771432,772736#msg-772736 Re: Benefits of Reduction Gearing? https://reprap.org/forum/read.php?14,771432,772736#msg-772736
Reducing microstepping doesn't affect either unless you go to full steps.

Changing to 0.9deg motors of the same length reduces the holding torque a little (you can see how much by looking at the motor data) but almost doubles the torque per unit angular error. So it improves positioning accuracy.
?
However, if your X and Y steps/mm is around 80 at x16 microstepping, then your motors probably provide more than enough positioning accuracy already, because the typical extrusion width of 0.5mm in much greater than the movement per microstep, even if friction in the system means that it takes 2 or 3 microstep to create any movement from rest.]]> dc42 Mechanics Sat, 10 Jun 2017 02:06:37 -0400 https://reprap.org/forum/read.php?14,771432,772699#msg-772699 Re: Benefits of Reduction Gearing? https://reprap.org/forum/read.php?14,771432,772699#msg-772699

Why not just use a 400 step per rev motor instead?
Because 1:2 gearing also increases torque, so the motor should theoretically be able to hold a position more accurately, however this has to be weighed against any backlash in the gearing system, and theoretically also against additional inertia in the now fater spinning motor itself.
Lower microstepping resolution could also make the motor louder.

Though i can't tell (yet) which option is better, i haven't experimented with that yet :P]]> WarriorMe Mechanics Fri, 09 Jun 2017 17:51:40 -0400 https://reprap.org/forum/read.php?14,771432,771462#msg-771462 Re: Benefits of Reduction Gearing? https://reprap.org/forum/read.php?14,771432,771462#msg-771462 the_digital_dentist Mechanics Fri, 02 Jun 2017 13:38:46 -0400 https://reprap.org/forum/read.php?14,771432,771440#msg-771440 Re: Benefits of Reduction Gearing? https://reprap.org/forum/read.php?14,771432,771440#msg-771440 [forums.reprap.org]

Most 3d printers will not benefit, as masses are low.
However, gear ratios allow you to use smaller steppers, and since print speeds are relatively low, there is no sacrifice.]]> prot0typ1cal Mechanics Fri, 02 Jun 2017 11:58:35 -0400 https://reprap.org/forum/read.php?14,771432,771432#msg-771432 Benefits of Reduction Gearing? https://reprap.org/forum/read.php?14,771432,771432#msg-771432 GrahamCracker Mechanics Fri, 02 Jun 2017 10:29:14 -0400
