Motors working then chatter before and after homing...

Why would the motor/motors work fine then chatter before homing and after homing?
Video of the behaviour? Bad connection at the motor? binding?
I vaguely recall the previous thread where we got your dual X axis going. It's been a while though, and in the meantime it's gotten a lot easier to do with RRF3 as Veti says.
Since you are picking things up again almost with fresh eyes, it might be a good idea to go through the update to RRF3. It would simplify the homing process for multiple independent motors per axis greatly.
For motor mapping
M584 X0:3 Y1 Z2:5 U3 V5 E4
would become
M584 X0:3 Y1 Z2:5 E4For axis minima
M208 X0 Y0 Z0 U0 V0 S1
would become
M208 X0 Y0 Z0 S1For axis maxima
M208 X800 Y500 Z400 V400 U800 S0
would become
M208 X800 Y500 Z400 S0For x endstop
M574 X1 S0
would become
M574 X1 S1 P"!xstop+!e0stop"For y endstop
M574 Y1 S0
would become
M574 Y1 S1 P"ystop"You could use dual endstops for Z if you wanted, or just use the probe.
You no longer need the endstops defined for U or V.
In these commands you could remove the references to U and V entirely.

As for updating, If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them. Reboot after each. Use M115 to verify the firmware has been applied.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Duet2and3Firmware-3.2.2.zip
That will get your firmware and DWC up to date. -
ok i updated to the latest via your steps good sir. Next?

Video of the behaviour? Bad connection at the motor? binding?
I did post a video in the original post. It's not a bad connection. Theres something different from normal movements and when its homed as you can see in the video.
EDIT: When i run the M115 it does say in the dwc its updated to the 3.2.2 but when i download the g files the top still says generated by RepRapFirmware Configuration Tool v2.1.1
also the panel due shows these errors:
m587 failed to add ssid to remembered list HTTP is enabled on port 80 FTP is desabled TELNET is disabled Error: M574 endstop type 0 is no longer supported. Use type 1 and invert the input pin instead. Error: M574 endstop type 0 is no longer supported. Use type 1 and invert the input pin instead.

M115 is correct. The text in the config files is just telling you what version of the config tool was used to make the config originally.

This means you should use the config.g I posted above to get the correct syntax for RRF3.
@wingtip said in Motors working then chatter before and after homing...:
m587 failed to add ssid to remembered list
You have a command in your config.g to add the SSID to the wifi module, but you shouldn't. It only needs to be sent once and then it's saved in the module itself. So remove any M587 from config.g.
The rest is all normal.

I've uploaded the config file but not going to do anything yet till i ask a question. What should my home x and home all look like under this new version 3 stuff since i had it set to split the axis then rejoin them..?
Thank you for the assistance so far.

For the homing files you can then remove the references to U and V entirely.
Since U and V don't exist anymore you only have to home them as if it was a single axis with a single motor. The main difference for RRF3 is that the endstops are defined to use 2 switches and it will continue to move the axis until both switches have been hit. It's much simpler than it was before.

@wingtip no. You wouldn't need m584 in the homing files at all and you would only need movement for x y z.
-
ok i tried to home x and immediately got an error something about a G1 S1 so i immediately shut down the power before it got to the end stops in case it wouldnt stop... here is my current home x settings
-
G1 S2 Z5 F6000
Change the S2 to H2 and any S1 to H1 in your homing files.
That is another change between RRF2 and RRF3. The S is now used for laser power. So H is now used for homing moves.
-
ok, its working using this new reprap 3 coding , HOWEVER, i still have the same issues. The motors move the gantry just fine. But the moment i hit home x, the motors chatter a few seconds, then move to home and after the second hit of the endstops it chatters again for a few seconds then stops... it only does it during homeing... any other time the motors move nice and quiet as they should.
Highly modified FT5 R1, ATX supply, mosfet w/silicone heat pad, bmg ext, TMC2600 drivers, and my custom quad z mod with 4 lead screws and custom cut new upper panels and bed, and using the dual z endstop mod. New project is 800x500x500z printer.

Video?
@wingtip said in Motors working then chatter before and after homing...:
The motors move the gantry just fine.
How are you moving the motors when it works if it's not homed yet?
Do the axis move ok by hand with the duet powered off? (do it slowly)
In the gcode console, can you send M122 and M98 P"config.g" and post the results here?

M564 S0 H0 ; allows movement of non homed axis for testing, and yes the axis move fine with the duet powered off. let me take a short short video

Sounds like your endstops may not be working.
The G1 H1 commands specify a max distance they will move trying to reach the endstop. When the endstop activates the movement stops otherwise the movement may continue to the limit of the axis.
Unrelated to that you have a command in your config.g file M574 Z1 S2 - that is invalid and not needed all at the same time.
From the docs:
Snnn 1 = switch-type (eg microswitch) endstop input, 2 = Z probe (when used to home an axis other than Z), 3 = single motor load detection, 4 = multiple motor load detection (see Notes).

While im waiting for the video to render, the code for the z axis is irrelevant right now as i have them unplugged. As for the comment about the endstops. both end stops trigger and can be seen in the dwc changing states... also, why would the motor chatter before it even moves and gets anywhere near the endstop...? You will see in the video and maybe understand better.... just waiting for my slow computer to render this so i can upload it to youtube and wait for it to process it , then post the link here...

I only mentioned it because the configurator often inserts that M574 Z1 S2 command even though it is incorrect.
why would the motor chatter before it even moves and gets anywhere near the endstop...?
It will certainly help to see the video. The only thing I have experienced like that affected all motor movements - not just homing.
Could you post the relevant homing file?
Thanks.

That is indeed strange that movement after M564 S0 H0 works fine, but homing behaves strangely. One thing that occurs to me is that it could be resonance due to the speed of the homing moves compared to the normal travel moves.
In the gcode console, can you send M122 and M98 P"config.g" and post the results here?

Can you also post your homeall, homex, and config.g as they are right now so we're all looking at the same code?
I notice in the video that when you are jogging it around it's with very short small moves. Have you tried longer distance moves yet?
