How could I source such closed loop positioners on the cheap? I know that harddrives have them, but as I understand them, the platter is part of the closed loop and actually needs to spin and data being read for the accurate positioning to work, so that makes them unusable to use for anything else other than fast oscillationby Genesys - Mechanics
I want to position a small load (aprox. 10g) within a quite small envelope (maximally 1x1cm) in the XY plane. Important aspects are accuracy, repeatability and most importantly speed/acceleration. Think having the object trace a star shape as quickly and as accurately as possible. What kind of actuator is well suited for this? I understand that a good answer would need more info on the actual spby Genesys - Mechanics
Oh, my bad - I meant G29, not G28by Genesys - Firmware - Marlin
No I’m not confused - if you move in 3 dimensional space with 4 axis, your system is overconstrained and may jamby Genesys - Firmware - Marlin
So how do I then set in my config the fact that my primary hotend is not at the center of the effector, such that when I G1 X0 Y0 Z0 the primary hotend will end up in the center of the heatbed? Also, does G28 affect the outcome of G33?by Genesys - Firmware - Marlin
Why would you want a 4th axis? That would over-constrain the systemby Genesys - Firmware - Marlin
A few questions about marlin & delta printer: 1. How do G33 and G29 play together? Which one to execute first and does the calbration of one affect the calibration of the other? 2. I have two hotends and one z-probe that are offset on the effector like so: +——————————+ | . . . . . . . . . . . . . . . . . . .| | . . . . . . . . .
