;The X axis to control the movement of the PnP head right and left. Right(Clockwise rotation to move Forward = S0) is positive.
;The Y axis to control the movement of the PnP head forward and back. Forward( AntiClockwise rotation to move Forward = S1) is positive.
;The Z axis to control raising and lowering of the PnP nozzle up and down. Up is positive.
;The V, U, W, A, B, C (for 6-Head nozzles) axes rotates clockwise and counter-clockwise. Counter-clockwise is positive.
;RepRapFirmware supports X, Y and Z axes as standard and allows you to create up to 7 additional axes depending on the firmware 
;version and which Duet you are using. Axes are created and associated with ;stepper motors using the M584 command in config.g. 
;You may use any of the following letters to refer to the new axes: U V W A B C D (letter D is not supported in older firmware versions)

;If no T parameter is given, then on boards having internal drivers the step pulse width and interval are guaranteed to be suitable for the on-board drivers only, 
;and will generally be too fast for external drivers. On the MB6XD board the default is T2.5:2.5:2.5:2.5.

; There are two parameters to be set for each endstop:

; S2 = Use Z probe (S2) and S3 = for using motor stall detection (S3).

; (2) Whether the endstop is at the minimum end (Low End) or the maximum end (High End) of the axis. 
; These are the X, Y and Z parameters. 0 = no endstop present(e.g X0) , 1 = an endstop switch at the Minimum end (e.g X1) , 2 = an endstop switch at the Maximum end (e.g X2) of the axis.

(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

When i did send M119 after that

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!

M566 X900.0 Y900.0 Z900.0 U900.0 V900.0 W900.0 A900.0 B900.0  C100.0 D100.0 'A100.0 'B100.0 'C100.0 'D100.0         ; set maximum instantaneous speed changes (mm/min)

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.

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.

Ian

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

@developeralgo222 does it lock up the same way as when connected to the 6XD? On the Mach3 board there’s nothing connected to enable. I suggested disconnecting the enable wires earlier.

With enable wires connected, M17 enables and M18 disables motors.

M17: Enable/Power all stepper motors
M18: Disable all stepper motors

Does this mean it only applies to Open Loop Stepper motors or even closed Loop ?

droftarts

@developeralgo222 Good point, I'm not sure. I don't have an external driver and motor setup to test.

Even with M17 included in the config.g for Duet 6XD. it does not move X and Y at all


; Enable All the drives 
M17  ; Enable All the drives

@developeralgo222 I asked this earlier:
Does it lock up the same way when enabled on the Mach3 board, as it does when connected to the 6XD?
On the Mach3 board there’s nothing connected to enable, which would seem to mean it needs an enable low signal. Have you tried disconnecting the enable when connected to the 6XD?

on MACH 3 it locks UP, when you power up and its energized and then when you config and Reset your MACH 3 , it unlocks and you can start jogging the motors right away . Looking at the schematics of the wiring diagram . it seems to indicate that the wiring should be

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

How can it be done on Duet 3 6XD ? . Duet 3 6XD must have a way of doing this ?
