Wiring Multiple Endstops in Parallel or Series with Duet 6XD

On the DWC console , when i send

M98 P"config.g"

i get "connection Interrupted HTTP request timed out" error with connection Lost, attempting to reconnect message and it disconnects DWC completely and i have to reboot manually. It does not even reboot or reset itself. Is that a bug on the RRF Software ? It seems it completely locks out Duet 6XD and i have to manually turn off the power and then power it back on. Even M112 does not reset it . Any reason why it would do that from the config.g ?
I am running RRF 3.4.6

Below is my current Full config.g

@developeralgo222 are you saying that it boots up OK and you can connect with DWC; but if you try to re-run config.g using M98, you lose the DWC connection?

If that's the case then I think it's most likely to do with the triggers. Try commenting out the M581 line(s) in config.g.

BTW you don't need to switch those inputs between being endstops and GpIn ports for triggers, because a trigger can monitor endstops as well as GpIn pins. See the line starting "X, Y Z or any..." at https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m581-configure-external-trigger.

@developeralgo222 I think your config.g crashing predated adding the triggers, but as @dc42 says, triggers in RRF 3.01 and later can read the endstop without redefining it as a trigger (older versions can't, and need to be redefined). Sorry I didn't spot this, it's been a while since having to set up endstops as limit switches! Comment out or delete the M950 J1 and J2 lines, add the endstop M574 X1 and Y1 commands back in, and change the trigger command to M581 T1 X Y S1 R0.

Some other things to try:

You have M17 very early in config.g, before any of the axes are assigned. I suggest moving to the end, or don't have it at all. The motors will all turn on as soon as one axis is commanded to move.

Your X axis limits are strange, I think swap them over, or maybe it should be M208 X1575 ... S0.
Also, your other limits:

; Axis Limits
M208 X0 Y0 Z-160 U-160 V-160 W-160 A-160 B-160  C0 D0 'A0 'B0 'C0 'D0 S1	; Set axis minima
M208 X-1575 Y2125 Z0 U0 V0 W0 A0 B0 C180 D180 'A180 'B180 'C180 'D180 S0	    ; Set axis maxima

I'm not even sure axis ranges should be from -[nnn] to 0, but I don't see why not. On a CNC machine, you have machine coordinates, and then work coordinates. This article looks like it covers this (and RRF supports) https://mhcc.pressbooks.pub/supportcnc/chapter/g54-g59-an-introduction/
It looks like OpenPNP is similar: https://github.com/openpnp/openpnp/wiki/Machine-Axes

The rest is mostly setting up the endstop triggers, endstops. However, you have setup all the sensors and valves with M558, which is used for defining probes! I think the sensors should be set up with M950 as inputs:

M950 J1 C"!2.io3.in"   ; Duet 3 3HC CAN_ID 2 Port 4- Vacuum Sensor Nozzle 1
M950 J2 C"!2.io4.in"   ; Duet 3 3HC CAN_ID 2 Port 5- Vacuum Sensor Nozzle 2
[etc]

with each input having a unique J[nn] parameter. Make sure the number doesn't clash with the triggers, though I expect you will replace these with endstop definitions.

The valves should be outputs, again set with M950, with unique P[nn] parameter:

M950 P1 C"!0.io3.in"   ; Duet 3 6XD CAN_ID 0 Port 4- Pump and Vacuum Solenoid Valve for Nozzle 1
M950 P2 C"!0.io4.in"   ; Duet 3 6XD CAN_ID 0 Port 5- Pump and Vacuum Solenoid Valve for Nozzle 2
[etc]

Please make these changes, post your updated config.g, and try sending M98 P"config.g" again.

@developeralgo222 You haven't changed the X axis limits; it still shows X0 as the minimum, and X-1575 as the maximum. Either swap them, or remove the minus from X-1575.

Otherwise, looks okay.

Ian

developeralgo222

@droftarts
when i test it manually according to the right-hand cartesian coordinates . My X-Axis moves Backwards from Home(Right to Left) instead of the Normal Forward ( Left to Right ) , that's why i was using Negative infront of that otherwise it crashes the X-Axis. If you look at the Endpoints and motor placements diagram above , you will see the description

droftarts

@developeralgo222 In that case, change the direction of the motor with the S parameter in M569, eg:

M569 P0.0 S0 T5:5:10:10

Then update the M208 command, and check it goes the right direction.

yes updated config.g and that fixed X-axis negative max issue

droftarts

@developeralgo222 Okay. Does it still crash when you send M98 P"config.g"?

Ian

droftarts

@developeralgo222 Another snag on homing; I checked with @dc42 if the trigger is ignored on homing moves. He said:

No, you have to deactivate the trigger.
..because after the homing move you need to move away form the endst9p to release it, to avoid triggering

So in your homing macros, rather than disabling the trigger pin and enabling the endstop, you need to disable the trigger itself, while homing. So now the homing macros will look like this:

M581 T1 P-1 ; disable trigger
 
[normal homing routine for X and Y axis in here]
 
M581 T1 X Y S1 R0 ; re enable trigger

@developeralgo222 See my reply before yours. You will need to edit your homing files.

Edit:
Using M950 J1 and J2 in your homing files to refer to limit switches will be messing with these in config.g:

; SMC NPN Vacuum Sensors -ZSE30A-01-N-L (Not Z-Probe)
M950 J1 C"!2.io3.in"   ; Duet 3 3HC CAN_ID 2 Port 4- Vacuum Sensor Nozzle 1

Not sure i understand what you mean by this ?

developeralgo222

@developeralgo222

i sent

 M98 P"config.g"

command and it disconnected again same issue. I don't know what is in the config.g that makes Duet 6XD crash ?

droftarts

@developeralgo222 never mind, you updated your homing files and have fixed it now. You can always check how pins are defined by sending, M950 J1 for example.

Ian

@developeralgo222

Also trying to get all the endstops on all Axis working. On the Z-Axes, i have 3 x Nema 17 Motors that are directly connected to 3HC board CAN ID = 1 , Drive 0,1 & 2. This are CAM Driven Axes

Motor 1 ---- On Drive 0 --- Rotates Clockwise or Anticlockwise to move CAM driven dual nozzles down and up on Z & U axis on CAN ID = 1 - Duet 3HC Drive 1.0 i.e Z & U-axes share a single motor 1

Motor 2 ---- On Drive 1 --- Rotates Clockwise or Anticlockwise to move CAM driven dual nozzles down and up on V & W axis on CAN ID = 1 - Duet 3HC Drive 1.1 i.e V & W-axes share a single motor 2

Motor 3 ---- On Drive 3 --- Rotates Clockwise or Anticlockwise to move CAM driven dual nozzles down and up on A & B axis on CAN ID = 1 - Duet 3HC Drive 1.2 i.e A & B-axes share a single motor 3

Trying to define them correctly in the config before updating the homing files. Here is a sample picture courtesy of @wayneosdias of where roughly the endstops for Z, U, V,W,A,B are located.

Two nozzles are at either end of the of the cam and at the center a stepper motor. At rest/homed both nozzles are at the Z max height and suspended this way by springs supporting against gravity. Once the stepper is activated, CCW the 1st nozzle is pushed down and the 2nd nozzle is suspended by the spring. Conversely when the stepper is activated CC the 2nd nozzle is driven down and the 1st nozzle is suspended at max z by the spring.

How do i get endstops for Z, U, V,W,A,B configured correctly ? Here is the snapshot of those Z-axes with drives and Endstops. I am not even sure that the Drives are configured correctly as per @dc42

@developeralgo222 For the timeout errors, are you seeing all your boards in DWC, and are they all on the same firmware? Go to Settings > Machine-Specific, should look something like this:

If it doesn't show there, send M122 to check mainboard firmware version, and M122 B1, M122 B2 and M122 B3 to check status of each expansion board.

The expansion boards must be on the same firmware version as the mainboard.

@droftarts

Only seeing B0 = 6XD, B1 = 3HC (CAN ID= 1) but not seeing B2 or B3 .A few days ago i could see all of them.They can connected fine. I did update all of them 2 weeks ago with same Firmware RRF 3.4.6

.

After updating to 3.5.0-rc.2 i can see all of them but i keep getting an error every minute about " Error: Expansion board 2 stopped sending status"

Error: Expansion board 2 stopped sending status

Screenshot 2023-12-18 163245.png

i will check the CAN cables and then reboot everything to see if it continues . After reboot , after a few minutes i started receiving the error again. Then i tried M122 B2 and i get

M122 B2
CAN response timeout: board 2, req type 6024, RID 91

@developeralgo222
Able to see them all after update and reboot
