Issues setting up duet wifi with dual x axis motors and endstops

[wingtip]

Thank you all for the help so far... currently the motors are moving again. here is my current config file. the current issue is with an endstop. I temporarily have everything unhidden so i can check the endstop status in machine properties and make movements to the x or U (my x2 motor).
If i do an x move say +10, BOTH POSTS MOVE. Ok no biggie at least they're in sync...

but if i do a U movement only the x2 moves. Ok no biggie that one will be hid later.

if i hit home x, both motors start moving together and heading towards home as they should. However, if i manually hit the x1 endstop with my finger the x1 motor stops and the U/x2 motor keeps coming as it should.. but when i trigger the endstop for that one the motor keeps coming until i have to E stop or power off before it tries to smash another endstop.

Ive confirmed in the machine status window the endstop works and will trigger but no matter which way i configure the endstop high or low etc it just ignores it so it has to be something elsewhere in the config...

So for reference:
x1 motor plugged into the x channel aka drive 0, this endstop plugged into the x slot

x2 motor plugged into the E1 channel aka drive 4, which is remapped as U4, this endstop is plugged into the E1 endstop channel.

I can’t open your config.g to check (typing on iPhone), but It’s probably not the endstop, it’s your homing script that’s the problem. The whole point of making the U axis is so that when you home the X axis, you home X and U at the same time, but independently.

First, check that the U endstop is triggering. Press the endstop switch and check it’s state changes in DWC, Machine Specifics tab, Endstops.

Then, edit Homex.g with something like:

G91 ; relative moves
M584 X0 U4 P4; splits X axis into individual motors, visible U
G1 H1 X-500 U-500 F6000 ; home fast
G1 X5 U5 F5000 ; move off Endstops
G1 H1 X-10 U-10 F600 ; home slow
M584 X0:4 P3 ; combine X motors 
G92 X0 ; tell firmware where we are
G90 ; absolute moves

You’ll have to copy this into homeall.g too. Hope that makes it clear.

@droftarts
when i edited to what you suggested with the H1 variable neither endstop worked..so i switched back to my original S1 and the x endstop works again but the x2 is still not recognising the x2 endstop (plugged into the E1, aka drive 4 slot) , and yes the endstop triggers in the machine properties as i said before...

im going to bed now but im going to post my gcode again as text since you were unable to open the text file. My current files are as follows:

@wingtip What firmware version are you on? Send M115 and post the reply. The only reason H1 doesn't work and S1 does would be if you are using firmware version 2.01 or earlier; from 2.02 they have the same function. See HERE. Which may also explain why the splitting of the axes and homing the two motors at the same time isn't working (though I thought this has been supported for a long time).

I also notice in Endstops section M574 E1 S0 ; position low, active low. Remove or comment this out. 'E' in M574 was only support in firmware 1.16 and earlier. See HERE. I'm not sure of the effect of this line, but may be being applied to the Extruder endstops and causing issues with U.

Apart from the above, I can't see any reason why the homing isn't working. Though you do need an G92 X0 after you re-join the axes in your homeall.g.

Also, as I said before, in Network section, remove M587 S"davet" P"helicopter" from your config.g. It will slowly kill the flash memory on the WiFi module.

@droftarts
I do believe it’s 2.01 but will let you know when I get home.
As for the network setting I’ll worry about that after I at least get the x axis working. Once it’s working as it should I’ll mount the cross beams and start engineering the carriage (y axis).

Thank you all for your patience in this.

left work early due to the christmas party

confirmed:

Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.01(RTOS) (2018-07-26b2)
WiFi Server Version: 1.21
Web Interface Version: 1.21.2-dc42

will try to update now and get back with you.

[wingtip]

Ok... im getting frustrated here but i think we're close. So right now here are my versions now.
Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.04 (2019-11-01b1)
WiFi Server Version: 1.23
Web Interface Version: 1.21.2-dc42

I also removed the Endstop line for E as mentioned. I verified the x2 endstop is in fact working and triggering when viewing the machine properties window. but im still not able to stop the x2 motor/aka U drive thats plugged into the E1 port with the enstop thats plugged into the E1 enstop port.

Looking at this image

the green circle shows the x1 motor/vertical post. the motor is currently at mid travel OFF the endstop and is displaying the correct status. This motor also stops correctly when it does get to the endstop

the red circle shows the x2 motor/vertical post that is plugged into the E1 motor port which is remapped to U4. The endstop is plugged into the E1 port. the motor is currently at mid travel OFF the endstop and is displaying the wrong status but does trigger when manually activated. the problem is it still does not STOP the x2 motor/vertical post aka U4. the motor still just ignores this endstop

the blue circle has me really confused... why is my E0, aka extruder showing a min of 0 and a max of 800 while the E1, aka the x2 motor only shows n/a despite clearly being defined in the config to be min 0 and max 800???????? uggggg im brain fried

[droftarts]

Update your DWC version, you’re using a very old one, may not be compatible, and give wrong info. It may assume an order for the motors that is incorrect. Use the latest version (2.04 or 1.22.6) from the firmware release DuetWebControl-SD-2.04.zip file or https://github.com/chrishamm/DuetWebControl/releases

This won’t affect the homing behaviour, but should give you the correct info!

It shouldn’t make any difference, but can you try changing the order of your M584 command? To M584 X0:4 Y1 Z2 U4 E3

Have you tried homing the U axis on its own? Try typing into console:

M584 X0 U4 P4
G91
G1 H1 U-800 F3000
G90

[wingtip]

well according the link you first gave me it said the zip file i downloaded should update everything but i will go looking for the webcontrol update real quick. However when i was testing the movements and endstops that was using the paneldue.

[wingtip]

i just tried the commands you suggested and still the same thing, the u starts to head to home and endstop is ignored the state says its triggered when its not suppose to be, then when i manually trigger it , it says triggered=no So you can see it working its just backwards . but its setup just the same as the x1 as both motors rotate in the same direction etc so the direction is correct and endstop settings should be the same since the x1 works perfect. Right?

the updated webcontrol is certainly different.. i dont like how it lessened the travel buttons from the +100 to now max travel button is +50.

You can right click on the buttons and redefine them.

[wingtip]

@Phaedrux Nice! told you guys im new to reprap and duets but im loving it so far despite the issues im having lol

[droftarts]

Is your PanelDue firmware up to date too? https://duet3d.dozuki.com/Wiki/PanelDue_Firmware_update

Is the wiring, or the endstop, different on the U axis to the X axis? Because that sounds like it’s inverted, which it isn’t in config.g

In the Fans section of your config.g, the comments of the two M106 commands seemed to had a return put in, so the words “turned off” and “turned on” appear to be on new lines. Lines must start with a Gcode or a comment mark (semi colon). I doubt this will change anything, but good to tidy it up!

I am running out of ideas as to why this isn’t working. My only other suggestion would be to swap the U axis with the extruder, so move the U motor to E0, and the U endstop to E0 Endstop pins, and test if it works there.

@droftarts
the paneldue is 1.21.4

[wingtip]

well im done... trying to update this panel due as suggested and its been a headache and now im to mad to continue for tonight... first off the enclosure i printed from thingiverse wasnt designed with updating firmware in mind and would be to much work to disassemble.... the designer left plenty of room for the other connectors but no way to get a micro usb plug to the board.. i had to sand down my plug to skin and bones to fit in the tiny slot he left for access... then when i followed the instructions on the web link provided after downloading bossa, my panel due now only displays a black screen and its not recognising it in windows so i cant get the port to use bossa to re upload the firmware....

ill see you guys in the morning

To see the U axis endstop properly, you need to make the U axis visible temporarily, by sending M584 P4.

good morning gents..... so after a nights rest and calming down i found another cable this morning and tried it and bam, it recognised it and gave me the port i needed and now have my panel due working again and updated to now 1.23.2.

so i went to try to home again and same issues... so in the new web control when editing it has a g code reference where before i was using some random web page... when using the reference from the webcontrol it seems to have some more updated info and i noticed this section and thought id give it a try

M574 - RepRapFirmware 3
Parameters

Xnnn Position of X endstop: 0 = none, 1 = low end, 2 = high end.
Ynnn Position of Y endstop: 0 = none, 1 = low end, 2 = high end.
Znnn Position of Z endstop: 0 = none, 1 = low end, 2 = high end.
P"pin_name" Defines the pin name(s) that the endstop(s) for the specified axis are connected to. Needed when S=0 or S=1.
Snnn Endstop type: 0 = active low endstop input, 1 = active high 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).
Order dependency

This command must be later in config.g than the M584 command that creates additional axes, or axes that have multiple motors and endstops.

Usage

The M574 command has been updated to allow for more flexibility. This includes supporting axes defined with multiple motors and multiple endstops (one per motor), use of non-default endstop inputs, and re-assigning endstop inputs.

Notes

Use a separate M574 command for each axis.
New parameter P gives the pin name(s) for the endstop(s) for the specified axis. If the number of pins matches the number of motors assigned to that axis, motors will be stopped individually when their endstop switches trigger.
New endstop type S4 means use motor stall detection (like S3) but if there are multiple motors, stop each one individually as it stalls. S3 means use motor stall detection but as in RRF 2: stop all relevant motors when the first one stalls.
Example

Old RRF_2.x code:

M574 X1 Y1 Z1 U2 S1 ; active high endstop switches, XYZ at min, U at max
New RRF_3 code:

M574 X1 S1 P"xstop" ; X min active high endstop switch
M574 Y1 S1 P"ystop" ; Y min active high endstop switch
M574 Z1 S1 P"zstop" ; Z min active high endstop switch
M574 U2 S1 P"e0stop" ; U max active high endstop switch
To use two Z motors using independent homing switches, declare two Z motors in M584, then declare two pins for Z endstops in a single M574 command. Example

M584 X0 Y1 Z2:3 E4
M574 Z1 S1 P"io2.in+io3.in" ; Z axis with two motors, individual min endstops, active high
The order of endstop switch pin names in M574 must match the order of Z motor driver numbers in M584. When homing Z, RRF_3 homes the motors of the axis at the same time, independently to their defined endstops.

so i briefly experimented with this in hopes this would solve my issues but still nothing. And im still noticing the 2nd endstop is still triggered on the wrong end no matter which way you configure it... i think i need to follow the advice to swap to a different port instead of E1/drive 4 but im off to work now and i will do some more suffering after work lol....

Sorry you're having difficulty. Probably would have been better to modify the enclosure rather than the PanelDue, though. It sounds like you have already deleted the firmware, and the USB is not making enough of a connection on whatever remains of the USB connector. You could solder a cut off USB cable's wires direct to the PCB, on the back where the pins are accessible. I'm checking to see if there's any other way to program the PanelDue apart from via USB (edit: fixed!). Have you got a Thingiverse link to the enclosure? Worth mentioning the problem in the comments.

I'm going to try and recreate your issue with the X homing today with a really simple set up (2 motors, 2 endstops and your config and homing files). I'll let you know how I get on.

You've probably been looking at the general reprap Gcode page https://reprap.org/wiki/G-code, which may not have the latest info on it, and has multiple versions of gcodes for how each different firmware interprets the commands! Best to use the Duet-specific one we curate: https://duet3d.dozuki.com/Wiki/Gcode. There are plenty of links in the documentation to our one, and in my posts where I've referenced gcodes!

M574 - RepRapFirmware 3

Unless you've updated your Duet firmware again, you are NOT using RRF3, you're using RRF2 v2.04. Make sure you use the correct section! https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_2_x_and_earlier

so i briefly experimented with this in hopes this would solve my issues but still nothing.

Okay! I'll test your setup and see what I get.
