Can you confirm that you are also running DSF version 3.2beta1 on the SBC?

@MathV said in External trigger doesn't call trigger#.g after software reset:

M581 PZ S1 T3 R0 ; call trigger3.g when a rising edge is detected on Z-endstop

That will be parsed as:

M581 P0 Z S1 T3 R0

Change it to:

M581 Z S1 T3 R0

PS - you can also recall the workplace coordinates, you will find them within move.axes[n].

There are two ways to use a Z probe to set the Z offset of a tool:

1. Use G30 S-2. This has been implemented for some time.

2. In RRF 3.2beta you can query sensors.probes[n].lastStopHeight and then use the result to calculate a new G10 Z parameter. I can't remember whether lastStopHeight is in 3.2beta1 or whether I added it subsequently, but the whatsnew file should mention it if it is in beta1.

@Gost101 said in BL Touch:

@dc42 The room temperature is 22.9C but can be low as 15.5C. The target temperature of the bed is 70*C.

Hmm, very odd then that it reported a gain (A parameter) of 30.8. The computed gain should be higher than the temperature rise during tuning. So if the indicated bed temperature was 22.9C when you started tuning, and it reached 70C, then the gain should be greater than 47. OTOH if the bed was already at e.g. 45C then you started tuning, then the computed gain would indeed be much lower than it really is. Tuning must start with the heater reading close to room temperature.

You could try using M307 H0 A55 C297 D23.

Please can you show in a video how you measured the tooth pitch to be 10mm.

@deckingman, good point, that aspect wasn't documented! I have updated https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M581_RepRapFirmware_3_01RC2_and_later.

What was the indicated bed temperature when you started tuning the bed heater? The low calculated A parameter suggests to me that it was well above room temperature, for example 45C or more.

Yes I approve a warranty replacement.

It's also possible to configure a trigger to work directly from an endstop, without configuring a GpIn pin for it.

@peter247 said in Bltouch do not work on PWM5 connector:

@dc42

I after checking it was heater 3 which I had problem with, not heater 5.

That's odd, because Heater 3 is a common choice for BLTouch.

If it's a 5V PSU without a mains ground connection, no need to opto isolate the servo control signal.

As you are not sure, I suggest you just ask for a warranty exchange.

Do you have a chamber heater, or just a thermistor?

• If you have a heater connected to E4 heater output, just leave out the X1 parameter in the M305 command
• If you have just a thermistor, use P103 and X5 in the M305 command

Looking at your video, there is no way that the belts you are using have 10mm pitch (distance between teeth). They look like 2mm or 3mm to me.

File start.g is run automatically when you start a print job from SD card. Please choose a different name for your custom start file, to avoid confusion.

@Veti said in Voron Switchwire CoreXZ:

i just checked M669 K2

M669
Kinematics is CoreXZ, matrix:
1.00 0 1.00
0 1.00 0
3.00 0 -3.00

The 3 is why you are seeing 30mm

try
M669 K2 X1:0:1 Y0:1:0 Z1:0:-1

The original CoreXZ design by Nicholas Seward uses a 3:1 reduction on the Z axis, so that the Z axis has a higher resolution than the X axis. That's why RRF defaults to that matrix. See https://reprap.org/forum/read.php?2,377858.

Which Duet and firmware version?

Please post your config.g file.

Are you doing the software reset when the external trigger is already triggered, or when it is not triggered?

@sozkan said in Giant Delta printer Slow Homing issue.:

Pulley 14 teeth at 10 mm pitch it should be 140 mm per revolution.

Are you really using belts with 10mm tooth pitch?

The heater outputs of all those boards should be good to at least 5A if you use properly crimped ferrules in the heater output terminal block. AFAIR the terminal blocks are rated 6A. The 2-pin Molex connectors on the Maestro should not be used above 2A.

The VIN fuse on the Duet WiFi/Ethernet is rated 7.5A. You might need to increase it to 10A if you use a 5A heater, to allow extra current for the motors and fans.

@dk, please can you do the following tests:

1. Connect the BLTouch to the tool board as usual, but instead of connecting the BLTouch control wire (orange or yellow) to IO0_OUT, connect it to ground along with the 2 wires already connected to ground. Then check whether the BLTouch does a self test when you power up the tool board.

2. Repeat but with the control wire connected to +5V on the IO) connector instead of ground. Does it do a self test at power up?

Note, in either case deploy/retract commands won't work, so don't try probing!

@oozeBot said in Duet 3 Toolboard extruder motor not idling down?:

Update- I believe this is only happening after printing. I just unplugged a machine for maintenance and monitored it when I brought it back online. It’s been 20 minutes or so and the extruder motor is cool to the touch..

Have you run the motor that is cool to the touch since you brought it back online? if a motor has not been used since the board was powered on or reset, then the motor(s) will not have been powered up.

@tristanryerparke said in 3v short from servo use on 1.04c, now board dead?:

ds3225 25kg

That's a larger servo than I've ever tested with. the largest I tested with put an 8V pulse into +5V. So I am fairly sure that is the cause of the problem.

I am surprised that nothing is getting hot. If the 3.3V LED glows briefly then goes dim, I would expect at least the 3.3V regulator to be getting hot, probably also either the SD card or the WiFi module.

Which country are you in?

To drive that servo I suggest one of the following options:

1. A separate 5V or 6V power supply (and don't drive anything else from that PSU), preferably with capacitor of 220uF or more connected between the output and ground.
2. A Schottky diode from Duet +5V feeding a capacitor of 220uF or more, then use the output from that to power the servo. The diode will prevent the pulse from the servo getting back into the Duet. This is the arrangement we have adopted on the Duet 3 boards.

It might be that just adding a capacitor across the 5V output would be sufficient, but without measuring the amount of power fed back from the servo, i can't be sure. Two servos will feed back twice the amount of power, increasing the size of the voltage surge.

Yes, https://www.dropbox.com/s/iw2wx23ta226b3c/Duet3_SDiap_Mini5plus.bin?dl=0.

You are welcome to try the firmware at https://www.dropbox.com/s/r65fl63ttvm6fh0/Duet3Firmware_Mini5plus.uf2?dl=0. Caution, I haven't tested it on a version 0.2 prototype, so far I only tested the slightly different build for the later prototype.
