2 independent Z motors and limit switches on Zmax
-
hello everybody,
I'm upgrading to fix the two Z axis threaded guides using for the Right motor Z1 and for the Left motor E1 and I'll use the M584 command like this:
M584 X0 Y1 Z2:4 U4 E3 P3 ; Driver 0 For X, 1 for Y, Z=2:4 U=4, Extruder 3
I wanted to insert two proximity sensors, on Z-max to align the motors, that I have in the company, these are Wenglor.

Who can help me in the configuration?

I tested the sensor.
powered at 24 V.
at open circuit it signals me 0.48V at closed circuit 0.78V. -
First off You don't need a U axis when using RRF3. And you should be using 3.2. The Z axis would be configured to use both drivers and the endstops would both be added to the Z axis endstop. No need for a U axis anymore.
I think that inductive sensor should work.
Instead of connecting to the zprobe connector you could use one of the endstop pins.

@Phaedrux
Ho installato la 3.2
Ok I also have a bltouch to level the bed.
My concern is the two screws on the motors.
I don't know if I need to work on them mechanically first since they are very wobbly.Obviously it is a Tronxy x5sa!
I think that solving the mechanical problems first, strengthening the two rods so that they do not dance anymore, is the best solution.
What do you think?
These are my configuration files:

@gdefranc said in 2 independent Z motors and limit switches on Zmax:
M574 Z1 S2 ; configure Z-probe endstop for low end on Z
To be able to use endstops for Z you would need to define them here like they are for the other axis.
-
Thanks @Phaedrux
For the BL-Touch I used pin H7, for the 2 Z-max endstops can I use H4 and H5?
How can I specify them in the M574 command? -
You can learn more about how pin names are used here as well as a list of available pins.
https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Pin_names
To make things easy for the endstops would you be able to use the actual endstop inputs? e0_stop e1_stop Z_stop?

Hello, I have 2 motors connected in Z (Z;E1) and connected to 2 drivers, but they drive at different speeds, it seems that they have different microsteps, what could be the problem?

@mr-lizard I don't see anything in your config to cause that. I suggest you start a new thread though.
