@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?

@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---

dc42 said in Configs for PCB PnP for Duet3D 6XD and 3 x 3HC expansion boards:

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.

--- 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).

@developeralgo222 Does DWC update the motor position after you send a G1 command? Or any messages in the console? What does M119 report?

I usually send G92 X0 Y0 Z0 to set the axes as homed, then I don't have to send G1 H2 commands, just straight G1.

I'd leave the timing on T5:5:10:10, it shouldn't hurt. 2.5us is at it's limit.

when i send a command like G1 H2 X10 , DWC will update the distance indicating X has moved but the Actual X motor does not spin to move on the X-axis , Same to Y-Axis

But still X and Y do not move at all .Not an even 1mm . They are energized and locked

DWC screen shows X and Y moved but nothing is moving.

@developeralgo222 I had a look at your wiring, and that looks correct. You mentioned earlier about the motor phases, did you check them? See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_connecting#identifying-the-stepper-motor-phases

Can you show how you have set the DIP switches? From what I can tell, they should be set as:
SW1 = on (86HSE8N motor)
SW2 = on (shouldn't matter, but clockwise)

For the microstepping, you've told the Duet to expect 40 steps per mm, and 50mm per revolution. That would be 50x40 = 2000 steps per revolution. The drivers don't seem to have a setting for that, so try 3200. 3200/50 = 64 steps per mm. Change M92 to that, eg

M92 X64 Y64

SW3 = off
SW4 = off
SW5 = on
SW6 = on

Note that M350 (microstepping) and M906 (driver current) are irrelevant for external drivers

I've just noticed your jerk, acceleration and maximum speed! These may be way too fast, especially if the driver is on the default 400 steps per revolution. Most likely, it's receiving steps so fast it can't move!

All of these are really high, and it may be jerk + acceleration that is stalling the motor. Try:

M566 X300 Y300
M203 X5000 Y5000
M201 X1000 Y1000

If that works, you can test to see how much you can increase those speeds. Though I'd probably go for a higher microstepping value for more accuracy in the X and Y axes.

@developeralgo222 I had a look at your wiring, and that looks correct. You mentioned earlier about the motor phases, did you check them? See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_connecting#identifying-the-stepper-motor-phases

Can you show how you have set the DIP switches? From what I can tell, they should be set as:
SW1 = on (86HSE8N motor)
SW2 = on (shouldn't matter, but clockwise)

For the microstepping, you've told the Duet to expect 40 steps per mm, and 50mm per revolution. That would be 50x40 = 2000 steps per revolution. The drivers don't seem to have a setting for that, so try 3200. 3200/50 = 64 steps per mm. Change M92 to that, eg

M92 X64 Y64

SW3 = off
SW4 = off
SW5 = on
SW6 = on

Updated the config.g, changed Drive Dip Switch settings for microstepping to SW1=ON, SW2=ON, SW3=OFF, SW4=OFF, SW5=ON, SW6=ON and attempted homing commands again and still no movement on X & Y axis

@developeralgo222 I'm running out of ideas. As far as I can tell, there's nothing stopping the Duet sending step pulses to the motor driver, and it thinks the drive is moving, because the axis position is updated.

I am wondering if the motor energising is a red herring, and it's not actually enabling, because it's not going into an alarm condition:

ALM：Alarm indicator light: ... if the red light is flicker three times within 3 seconds, that means position ultra difference or the encoder connector is disconnected.

I don't think it's even registering it should move, because the driver is not enabled. Does the motor energise as soon as power is applied to the driver (with the Duet off), or only once the Duet is turned on?

How is the 3-pin 'Driver active enable select' jumper, next to Driver 1, set? I think the jumper is between EN_POL and GND, which should be correct for this drive:

The Enable output is either low when "on" and high impedance when "off", or vice versa, depending on the position of the 'Driver Enable Polarity' (En_Pol) jumper.

Also try changing M569 R parameter to R0:

Rnnn Driver enable polarity: 0 = active low, 1 = active high, -1 = driver is always disabled and is not monitored (default 0)

Another option is to try disconnecting +5V and -EN from the stepper driver, because external drivers are often active with no signal on the enable line, to allow for simpler systems which only have step and direction outputs.

The only other thing I can think of is to put an oscilloscope on the Duet outputs.

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

(2) M98 P"config.g" when sent it disconnects and nothing happens

I would start investigating this issue first, because it is a critical error. You might damage the onboard 5V regulator if it's a overcurrent shutdown...
Other stuff might solve itself after you've found the reason for the disconnects.

I finally got a MACH 3 Controller board and MACH 3 software to test the X & Y Axis motors( NEMA 34 8.5N.m (86HSE8N-BC38) ) and External Driver (HSS86) . The Motors work fine no issue they are able to move Left to Right on X-axis and Forward and back on Y-axis. Confirming that the following connections from Motor to Driver are correct (NEMA 34 Motor Power & Encoder connections) The only thing i changed for the test is the Signal wiring to comply with the MACH 3 Controller

On Duet 3 6XD

Signal Connection:

External Drive (HSS86) --------> (Cable Color) ------> Duet 3 6XD Drive_x

• PUL+ , DIR+, ENA+, ALM+ --------> (Red) ------> 5V_EXT
• PUL- --------> (Blue) ------> Dx_STEP-
• DIR- --------> (Yellow) ------> Dx_DIR-
• ENA- --------> (Green) ------> Dx_EN-
• ALM- --------> (Black) ------> Dx_ERR

On MACH 3 Control Board with USB Motion Driver RnRMotion.dll installed

Signal Connection:

External Drive (HSS86) --------> (Cable Color) ------> MACH 3 Controller X-axis

• PUL+ --------> (Red) ------> XP
• PUL- --------> (Green) ------> GND
• DIR+ --------> (Yellow) ------> XD
• PUL- to DIR - (Drive side only) ----> (Black)

It seems on MACH 3 if you compare it to Duet 6XD connections it seems they are reversed as @droftarts mentioned

• PUL+ --------> (Red) ------> XP ( Dx_STEP+ )
• DIR+ --------> (Yellow) ------> XD ( Dx_DIR+ )
• ENA+ --------> (Blue) ------> XE ( Dx_ENA+ ) ******?
• ALM+ --------> (Black) ------> XA ( Dx_ALM+ ) ******?
• PUL- , DIR-, ENA- , ALM- --------> (Green) ------> GND

It seems the issue is on the Duet 3 6XD side configuration and the signal connection from the external drive. Not sure how to do this on Duet 6XD

@developeralgo222 it looks like the driver is switched the other way around from ‘normal’ drivers, in that it needs a +5V signal with a common ground, rather than having a common +5V that is pulled to ground by a signal. It’s a shame the data sheet is so sparse on details. Where did you find the info on wiring up the Mach 3 controller?

I’ll have to ask @dc42 in the morning if the 6XD can do that.

If you are thinking it’s a configuration error, especially if sending M98 P"config.g" causes a reset, create a basic config.g that only sets the X and Y axes.

Just on youtube and google search , an online user made a demo on how to test the same setup on youtube and someone explained how to connect MACH 3 controller and to NEMA 34 motors

MACH 3 Controller connection to HSS86 Drive + Nema 34 closed Motor

MACH3 Controller installation and Wiring

This is a very simple NEMA 34 closed Loop/External Drive connection to 6XD not sure why it would not work
