@belgianguy Correct, I was indeed on an earlier version where this problem didn't occur. Thanks for the extra information.

@juls said in wifi 2 Board skipping steps:

RepRapFirmware for Duet Wifi/Ethernet version 3.4.6

Have you tried updating firmware to 3.5.2 yet?

If the issues stays with the Y axis itself regardless of drivers than it makes me think it's a mechanical binding issue. How heavy is the Y axis?

@qurt You could use the HTTP requests API and talk to the Duet Board via LAN. https://github.com/Duet3D/RepRapFirmware/wiki/HTTP-requests

Did you replace the wifi module? The soldering there doesn't seem stock. When you replaced the SD card reader perhaps the wifi module soldering was melted as well causing a poor connection.

@bierent said in Duet no wifi anymore:

I checked the solder connections and they are allright.

Which did you check and how did you check them?

Also, are you connecting the external antenna?

I've moved the messages from the 2-year-old thread (https://forum.duet3d.com/topic/27374/duet-3-mainboard-6hc-motors-not-working/) to this one.

@kmjr20 It may help to also define a tool - M563: Define or remove a tool

@droftarts Still on 3.5.2. About to start some long prints . We will see if it works in a few days. Again I thanks you. John.

I have now implemented a fix (the same as Tim's fix) for this issue in the 3.5-dev and 3.6-dev source code, so it will be included in the next builds. I can provide temporary 3.5.2+1 builds if anyone needs them.

@nick9one1 said in toolboard endstop problem:

I removed the 1LC, reflowed the connectors with plenty of flux and cleaned with IPA - now working.

Sorry you received a poorly soldered 1LC. Do you have a picture of it before you resolder it?

But the part cooling fan doesn't start automatically. If I use the fan slider once the print has started it does work.
The slicer is set to enable it at layer two.

Your config:

M950 F1 C"121.out1" Q250 ; create cooling fan 1 on pin toolboard out1 and set its frequency M106 P1 S0 H-1 B1 C"Part Cooling Fan" ; set fan 1 value. Thermostatic control is turned off ; Tools M563 P0 D0 H1 F1 ; define tool 0

The part cooling fan F1 is defined as being part of tool 0, so any M106 S# command should turn it on or off. Either your slicer is outputting a P parameter (so trying to turn on a specific fan and not the part cooling fan), or it's setting S below the speed that the fan turns on at. So check the Gcode for M106 commands, and see what it is sending, then check by sending the same command. M106 S255 (or M106 S1) should set it full on.

Your config has the fan frequency as Q250, ie 250Hz. Check that the fan spins up when setting low PWM values - some fans don't like running on PWM, but changing the frequency can help.

@sfiamma87 said in Connect/Disconnect Toolboard with printer powered on:

The only problem is that I cannot keep the toolboard detached without opening the CAN bus circuit. Theoretically, I could use a board with a short circuit, couldn't I?

You could try wiring the toolboards as a stub, ie with just two wires (CAN_H and CAN_L) going to the toolboard. Do not terminate the CAN bus on the toolboard, terminate the bus at the last CAN device. eg something like this:

Where "Expansion 2" would be where you wire the swapping boards. You definitely want to pause the machine until the toolboard swap has happened, CAN has reconnected, and toolboard config is loaded.

@jay_s_uk

Hi Thanks for replying, yes its a Moulded cable, found the issue though.

in my school boy error moment when I killed my first Roto Board, I also killed my super pinda and roto 3 wire fan.

it looks like during the initialisation M950/M106 because the tach output from the fan was dead it gave the error, a replacement fan arrives this morning so I will be able to confirm it later.

all in all its was a very costly error.

regards

@jay_s_uk said in Duet 3 mini 5+ CAN connection with Bigtree Tech EBB36:

@kirill_maker you have a choice of the following toolboards that are compatible with RRF
Duet3D 1LC
Duet3D Roto
Mellow Fly-RRF36
Mellow Fly-SHT36 Max V3
Mellow Fly-SB2040 Pro V3
Mellow Fly-SB2040 Max Pro V3

Thanks! Will try!

@acnev nope, no resistor needed. just i0[#].in -> wire -> button -> wire -> gnd

@o_lampe it’s the Duet 2 WiFi/Ethernet that is slowly losing features (or rather not gaining new ones), due to memory limitations as it has 512Kb flash and 128Kb RAM. No problem on Mini 5+, which has 1Mb flash and 256Kb RAM, at the same speed as Duet 2 at 120MHz. The 6HC and 6XD has more memory, at 384Kb, are faster at 300MHz.

@droftarts thanks. I turn it off at night, and turned it on this evening and it's blinking slowly now. It's like going to the doctor and suddenly feeling fine.

I'll follow-up or re-post if it starts happening again.

@j-pickens Yes. You can actually wire the toolboards to either pair of the tool connector, ie 1 and 2, or 3 and 4. Electrically it shouldn't matter which pair of pins you use. This also means you can wire two toolboards to each connector, one on each pair of the tool connector. I haven't actually been able to test this, but can't see any reason why it shouldn't, so it would be good to check it works. Make sure all 2-wire connections are each under 1m long.

Ian

@gloomyandy This makes sense given out1 is PWM switched to ground. Measuring the voltages between V_IN and out1 gives the correct voltages with M42 P5 S0 and M42 P5 S1.

I have changed my connections as follows to make it work:
(+) of Air Solenoid --> out1 V_IN on OUT 1 in Tool RR
(-) of Air Solenoid --> GND out1 on OUT 1 in Tool RR

@wmdeveloper Great, glad you were able to fix it. Let us know if you have any other issues.

@RockB Yikes, that's poor. The assembly company must have had the trainees on the tools that day! Yes, no problem, we'll replace under warranty. Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.

If you don't want the hassle of waiting for a replacement, and you're comfortable waving a soldering iron around, I'm happy if you want to clean up the solder yourself, and we'll continue to honour the warranty. Though it would be good to get that board back and show the assembly company!
