Motors working then chatter before and after homing...

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..?

@Phaedrux said in Motors working then chatter before and after homing...:

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.

but do i still need to split the axis during homing, the M584 command?

homeall.g
homex.g

Phaedrux · 4 Mar 2021, 02:28

@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

homex.g

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.

Video?

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?

home x is the only one im using at the moment.

i up'd the current from 1amp (1000mah) to 1.2amp (1200mah) and no change

What is the max rated current for the motors?

unfortunately at the moment i cant due to the huge mess lol... but months ago i was running it the full distance of 800mm no issues

Ill have to check as they came from openbuilds.com but from the config file you gave me they are now down to 800 mah and still chatter before and after homing..
