@atfphoto That's a huge printer! I am using a Tevo Little Monster with stock motors, I'll look into whether or not the cables are shielded. Off the top of my head, I don't think they are.

Thanks for the response, I hope this solves the issue!

@alankilian Thanks for your time, I really appreciate it.

@alankilian I've connected DI-1 and DI-6 ~ DI-8 to the internal 24v power supply at "VCC". The servo drive screen shows "0"

@alankilian I do not. As I understand it, you can turn off the drive enable signal through the menu on the servo drive.

Same goes for DI 6 - DI 8

Everything is disabled.

Here's the overall wiring diagram for the system. It doesn't really drill down into how to wire the step / direction inputs for the servo drive, so I used my best judgement.

@kzamani

I should note, I have the wiring as follows:

Duet 2 -> Duet Breakout Board
Drive 9:

Step + -> "Pulse"
Step - -> "/Pulse"
Dir + -> "Sign"
Dir - -> "/Sign"

Furthermore: The drive is configured to run in Pt mode, and is wired according to the diagram shown on page 20: https://cdn.automationdirect.com/static/manuals/sureservomanual/ch2.pdf

Hello everyone!

I am in the process of installing an MDPE-10 extruder onto an existing printer system. The system uses a Duet 2 Ethernet controller, sending step / dir signals to servo motors mounted on each axis.

The new MDPE-10 extruder requires the use of a Sure Servo SVA-2100 servo drive. There's a plethora of information for the servo drive located here: https://cdn.automationdirect.com/static/manuals/sureservomanual/sureservomanual.html

I can drive the servo motor using the controls on the servo drive, however the step / dir signals sent from the Duet are not turning the motor. Current motor configuration looks like this:

; Drives
M584 X5:6 Y7 Z8 E9  P:4			  						; Set drives for all axes to be driven from I/O port and CONN/LCD ports
M671 X-320:1566 Y603:603 S60 								; Set ball screw positions for probing routines, maximum error correction is 60mm or 3 rotations of the ball screw.	
M569 P5 S1  T2:1:0.25:0                           			; Drive 5 goes forwards - X axis 1 - timings for all motors based on clearpath servo drives
M569 P6 S1  T2:1:0.25:0                           			; Drive 6 goes forwards - X axis 2
M569 P7 S1  T2:1:0.25:0                           			; Drive 7 goes forwards - Y Axis 1
M569 P8 S0  T2:1:0.25:0                          			; Drive 8 goes backwards - Z Axis 1
M569 P9 S1  T5:5:5:5                           			; Drive 9 goes backwards - Extruder Drive 
M350 X16 Y16 Z16 E16  I1                           			; Configure microstepping with interpolation
M92 X320 Y320 Z320.00  E50	                   			; Set steps per mm
M566 X600 Y600 Z300  E80                   		   			; Set maximum instantaneous speed changes (mm/min)
M203 X24000 Y24000 Z2400  E12700            	   			; Set maximum speeds (mm/min)
M201 X750 Y1250 Z500  E250			  			   			; Set accelerations (mm/s^2)
M906 X800.00 Y800.00 Z800.00  E800.00 I30  		   			; Set motor currents (mA) and motor idle factor in per cent
M84 S30                                           			; Set idle timeout

The 5:5:5:5 timing is there strictly as a test, since I am unclear on the timings for this particular servo drive.

Any help would be greatly appreciated.

Perfect. Thanks for the information!

Does the PWM capability matter if I need to switch on a relay or power a solenoid?

Hi,

Can the endstops be configured similar to how fans can be configured as switches? In the current firmware, I can use the following command to define a GPIO pin which can be controlled with m42:

M950 F2 C"nil" 									; disable fan 2, free pin to be controlled by m42 command
M950 p3 C"fan2"									; setup fan 2 to be controlled by GPIO port 3

Can something similar be done with endstops?

Hello! Long time user of the Duet 2 ethernet, moving to firmware 3 now. One issue I have not explored is whether or not an endstop can be used as a g-code controllable switch? Looking towards future expansion in some of my printers, it would be useful to control E0 / E1 endstop pins as switches.

Thanks,
Kevin
