Title: Your expertise on Z axis please
Post by: KwisatzHaderach on April 21, 2019, 07:05:13 PM
I purchased a Z axis for my eleksmaker

The amazon link is here https://www.amazon.com/Travel-Length-Linear-Actuator-Sfu1402/dp/B01L6W1GRG/ref=sr_1_fkmrnull_1?keywords=100mm+Travel+Length+Linear+Stage+Actuator+DIY+CNC+Router+Parts+X+Y+Z+Linear+Rail+Guide+Sfu1402+Nema17&qid=1555898193&s=gateway&sr=8-1-fkmrnull (https://www.amazon.com/Travel-Length-Linear-Actuator-Sfu1402/dp/B01L6W1GRG/ref=sr_1_fkmrnull_1?keywords=100mm+Travel+Length+Linear+Stage+Actuator+DIY+CNC+Router+Parts+X+Y+Z+Linear+Rail+Guide+Sfu1402+Nema17&qid=1555898193&s=gateway&sr=8-1-fkmrnull)

Here are some specs

Feature:
Guide: 12mm
type: linear system mould
duration of travel: 100mm
Balls crew type: sfu1204
level ball screw: c7
stepper motor: include
Stepper motor: nema17
Motor size: 48*42
Step angle: 1.8
Number steps per turn: 200 steps
Inductance of coil windings: 10
Resistance of coil windings: 3.5
Horizontal load: 20KGS
Vertical load: 8KGS
Speed: 1-66mm/s

I am quite impressed with it just based on handling it out of the package. I am much impressed that it has zero slop.


I have this wired to connect to connect to the eleksmaker 3 axis board:

With the 24v 1.5a will it destroy the eleksmaker mana 3 axis board?  Is it likely that 24v 1.5a are the maximum loads? 

I have followed Zax on adjusting the pots on the driver provided by eleksmaker, could someone please advise on what the voltage should be for this stepper?

Nice looking unit, ball screws generally have very little backlash but offer fast motion. They are superior to leadscrews.

The stepper drivers are rated at 2A when you have a heatsink and fan, without they are only good for 1A.

The Mana board is designed for 12V which should be sufficient, you'll just get slightly lower torque.

Thank you for your input. Hopefully it all works out well.
