Configs for PCB PnP for Duet3D 6XD and 3 x 3HC expansion boards

[droftarts]

@developeralgo222 please post your homex.g and homey.g. Do all the other axes home correctly? If you run homex.g on its own, does the axis move at all? Is there any more messages in the console while or after homex.g has run?

• X and Y Axis do not home at all

• Z-Axes ( Z, U, V, W, A, B ) homes but not correctly

• Only Rotational Axes ( C , D, 'A, 'B, 'C, 'D ) = ( C, D, a, b, c, d) home correctly

Below are my current homex.g and homey.g

@developeralgo222 Your X and Y endstops are set as axis low end (ie where X=0) endstops:

M574 X1 S1 P"!io0.in"               ; configure switch-type (e.g. microswitch) endstop for low end on X via pin io0.in
M574 Y1 S1 P"!io1.in"               ; configure switch-type (e.g. microswitch) endstop for low end on Y via pin io1.in

Whether the endstop is at the minimum or maximum end is defined by the number after the axis label, ie X or Y, in M574

Xnnn Position of X endstop: 0 = none, 1 = low end, 2 = high end.

However, your homing script tries to home the X axis to the high end (Y is the same):

G1 H1 X235 F1800    ; move quickly to X axis endstop and stop there (first pass)
G1 H2 X-5 F6000     ; go back a few mm
G1 H1 X235 F360     ; move slowly to X axis endstop once more (second pass)

Where is each endstop actually located, low or high end? Check the other linear axes for the same issue.

Edit: when the endstop is triggered, the axis position is set to the low or high number (depending on whether it's a low or high endstop) in the M208 commands:

; Axis Limits
M208 X0 Y0 Z-50 U-50 V-50 W-50 A-50 B-50  C-180 D-180 'A-180 'B-180 'C-180 'D-180 S1	; Set axis minima
M208 X450 Y500 Z50 U50 V50 W50 A50 B50  C180 D180 'A180 'B180 'C180 'D180 S0	        ; Set axis maxima

Edit 2: You also need to move the axis far enough to actually trigger the endstop. Your X and Y axis moves are X235 and Y215, but the axis length is X450 and Y500.
Also, check you motors are actually going the way you expect. The origin (X0 Y0) usually in the front left corner, a +X move should move to the right, a +Y move should move the tool towards the back, relative to the 'bed'. If you have a moving bed (which I don't think you do), the bed would move forward. If the axis moving the wrong way, change it with the M569 S parameter. All yours are S1; some may need to be S0, to change the direction.

@developeralgo222 said in Configs for PCB PnP for Duet3D 6XD and 3 x 3HC expansion boards:

Z-Axes ( Z, U, V, W, A, B ) homes but not correctly

Regarding your setup of the 6 nozzles, you say they are set up as:

Nozzle Pair, Shared Z Axis, Cam
A nozzle pair share a Z axis motor. The two nozzles are pushed down by a rotational cam, pulled up with a spring

Is this how they are actually set up? I would think this means you only need 3 Z axes, and a way to actuate the cam; this is usually done by going to the end of the axis and hitting a bump stop that flips the cam. Does yours do something different? With the option you have selected, the gcode openPNP produces likely only contains commands for 3 Z axes.

@developeralgo222 said in Configs for PCB PnP for Duet3D 6XD and 3 x 3HC expansion boards:

i really need help on this configuration setup for a PNP machine. i am new to Duet 3 board but it was highly recommended. Not sure is there is any true support for Duet 3 6XD and 3HC Products.
There is a ton of documentation and help on how to setup 3D printers but almost non-existent support or help on how to correctly setup PnP machine using Duet 6XD and 3HC boards apart from very few users in the forum who are trying similar setups.
This is very frustrating for Duet board users

The forum is the way we offer support; you bought Duet hardware, not a support contract. You are building a very complicated machine, which you haven't fully described (position of endstops, how the nozzles are activated/switched). You are on a learning curve to implement this with Duet and RRF, and you are jumping in at the deep end. It takes us time to go through your posts, to understand the layout of your machine, and what you are trying to achieve. OpenPNP users are a small fraction of our users, and we don't have an OpenPNP test setup to be able to try out the options, just like we don't have every kind of 3D printer, or CNC machine. For some areas, you would be better served by asking on the OpenPNP forums/Discord/wherever for advice. So, please, be patient, we're learning as well.

Yes that's how it's setup. On Each each CAM pair there is an end stop on each axis (2 Nozzles , 2 Endstops on the shared Z-axis )

@developeralgo222 thanks. Please let is know what issues remain when you have corrected the issues identified by Ian 3 posts up from here.

You may find https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_cartesian useful because it describes how config.g should be set up to control the axis motors and how the homing files should be set up.

[developeralgo222]

@developeralgo222

Here is an illustration to capture the PnP machine build so that anyone willing to help can visualize my build

[developeralgo222]

@dc42 Is there anyone who can work with me to come up with a working configuration for this PnP Machine. It will also help those who want to take the dive with Duet 3 6XD, 6HC and expansion boards in building PnP Machines to at least have sample config.g and homeall.g that they can use and play around with. I will buy him/her coffee or beer for a week !!!!!

[dc42]

@developeralgo222 please read the page I linked to in my previous post and the advice from Ian. That should give you enough information to get X and Y homing properly. Further advice:

1. Test motor movement like this:

• Send G91 to put the machine into relative movement mode
• Use G1 H2 commands to command individual motors regardless of their homed status. For example, G1 H2 X10 should move the X axis by +10mm, and G1 H2 X-10 should move it by -10mm.

2. Read the endstop states, either by using M119, or in Duet Web Control start the Object Model Browser and expand sensors/endstops. Check that the state changes as expected when you operate the endstop.

@dc42
In trying to troubleshoot the homing Failure for X and Y axis, I noticed that when NEMA 34 Closed Loop Motors ( 86HSE8N-BC38 8.0N.m ) with External Driver (HSS86) are energized(48V Power is applied ) it locks, as it should, but does not move when i try to home it even after changes . Without Power applied i can move it manually and moves fine as expected

i have double checked all Wiring from Motor <---> Driver <--> Duet 3 6XD and seems correct as expected, No error light on the Driver or Duet 6XD

• I am thinking that one of Motor Power (A+, A-, B+, B-) internal wires might be crossed or swapped or

• PSU Output supply 48V DC @ 12.5A Max . is this an undervoltage issue ?

Looking at the Datasheets of both the Driver and Closed Loop Motor, it seems to suggest that the recommended DC is 60V while some documents say 48V . i am perplexed on this. Any one with an idea about this motors or drivers?

[droftarts]

@developeralgo222 have you ever got the X and Y axes moving? I notice you haven’t got a T parameter in your M569 command for X and Y:

M569 P0.0 S1 R1                  ; X-Axis physical drive 0.0 goes forwards on CAN ID = 0 - Duet 6XD Drive 0.0
M569 P0.1 S1 R1                  ; Y-Axis physical drive 0.1 goes forwards on CAN ID = 0 - Duet 6XD Drive 0.1

T controls the timing of the step pulses:

Taa:bb:cc:dd (firmware 1.21 and later) Minimum driver step pulse width, step pulse interval, direction setup time and direction hold time, in microseconds

I haven’t ploughed through the drive manual, but try T5:5:10:10 eg
M569 P0.0 S1 R1 T5:5:10:10

@developeralgo222 the motor voltage is unlikely to be critical. Higher voltage allows movement at higher speeds before torque drops off.

Please provide a link to the datasheet of the motor driver, and show us how you have connected it to the 6XD.

I have not got X and Y to move, The Motor is energized fine, no errors on the driver but they don't move. No meaningful error on the Duet Web Control console. i have updated config.g and other files as per suggestions here from users but to no avail.

[sebkritikel]

@developeralgo222 I know several people are trying to help you (and I'll try to where I can as well), but can you do the following?

1. Post your latest config.g file
2. In the console type M98 P"config.g", and post what the results are.
3. Can you please verify if you have tested X and Y motor movement like dc42 has described below---

• Send G91 to put the machine into relative movement mode

2. Read the endstop states, either by using M119, or in Duet Web Control start the Object Model Browser and expand sensors/endstops. Check that the state changes as expected when you operate the endstop.

--- and let us know what happens (nothing? error light on the HSS86 driver?)
4. What do you have the microstep settings set to on the driver (with the SW3、SW4、SW5、SW6 switches)

While we are trying to help you 'piece by piece', it is very helpful for us if you respond by answering all the questions previously asked - it helps us work out what could be going wrong. In addition, posting your updated config.g once you make changes is extremely important, as it helps us 'peer review' the changes that have been made. If we can't see the config.g file, we won't be 100% sure with whats going on.

(1) updated above in this post Config.g
(2) M98 P"config.g" when sent it disconnects and nothing happens
(3) tested X an Y movement independently as @dc42 suggested and none moves at all
(4) double checked all the connections again, no alarms or short circuits
(5) The Endstops for X and Y

M119
Endstops - X: at max stop, Y: at max stop, Z: at min stop, U: at min stop, V: at min stop, W: at min stop, A: at min stop, B: at min stop, C: not stopped, D: not stopped, a: not stopped, b: not stopped, c: not stopped, d: not stopped, Z probe: at min stop

i will adjust endstops correctly once i get X and Y moving since no triggers will happen if X and Y dont move at all

(6) Microsteps is set to defaults (400) : SW1 = ON ( selects 86HSE8N-BC38 ), SW2=ON, SW3=ON, SW4=ON, SW5=ON,SW6=ON

(7) checked the internal encoder wires at the back of the NEMA 34 motors and they are fine ,no crossings . They are correct as per the wiring listing on the side of the NEMA 34 motor

@developeralgo222 said in Configs for PCB PnP for Duet3D 6XD and 3 x 3HC expansion boards:

If M119 is reporting that the X and Y axis are at the max endstop, the axis won't move. Try changing the endstop configuration, removing the invert flag (!), eg

M574 X2 S1 P"io0.in"               ; configure switch-type (e.g. microswitch) endstop for low end on X via pin io0.in
M574 Y2 S1 P"io1.in"               ; configure switch-type (e.g. microswitch) endstop for low end on Y via pin io1.in

The endstops should report 'not stopped' with M119, then, and the axis should be able to move. You can tell if it does move, because the machine position will change in DWC. If this moves, and your motors don't, then there's another reason, eg motor not actually enabled.

Alternatively, send M564 H0 S0 to allow axes to move that aren't homed, and allow axes to move outside the bounds of the printer. USE CAREFULLY! See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m564-limit-axes

@developeralgo222 I've also had a look at the HSS86 datasheet, and it doesn't have any information on timings to use beyond

frequency 0~200KHz

200KHz is a pulse and interval every 5us, so it should be able to do T2.5:2.5:10:10 (no information on the last two parameters, direction set up and direction hold).

Removed ! and tried again and X & Y are not moving at all. The X and Y are energized and the Motor is still in lock
