Stuck in spin loop, spinning module G-Codes

Good morning,

Here I leave the config.g and triggers2 and 3

I leave you an image of how the Duex is connected, it is powered directly from the 24V source

Hi,

Did you read this about power wiring when having a Duex5?

Important! You must have a reliable low-resistance connection between the negative (ground) terminals of the two VIN terminal blocks. Failure to do so may result in high currents flowing in the ground connectors of the ribbon cable and may cause damage to the Duet 2 or Duex. Preferably, make this connection using either solid core wire, or stranded core wire with ferrules of the correct size crimped on securely. Re-tighten the terminal block screws regularly for the first few days of use, to make sure there is no creep in the wires causing the screws to become loose.

Hello,

I would say yes, the Vin input is with a proper wire and both motherboards are connected directly to the outputs of a MeanWell source, the data bus is the one that comes with the duex5 electronics and during the operation it does not seem to heat

The electronics restart if any temperature is reached?

fcwilt

Hi,

Just to give you another perspective.

I took the idea about a direct power connection between the two boards rather literally.

The black and red wires connecting the boards are solid 14 gauge.

Connected in the middle of those two wires are stranded 14 gauge wires running to the power supply.

Phaedrux

Yes I believe you will need to correct your power and ground connection between the duet and duex as shown by @fcwilt and described here: https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features#Section_Wiring

Aitor

I have made the changes in 4 machines (all of them identical) but two of them have already stopped, in one of which has stopped, I put a power supply of higher capacity to test it and also stopped

Could the problem be the G-code or something in Simplify??

It does not always fail. If I reboot the printer, most of the time, the first printing works well but the next one has the problem. Working with the same G-Code.

Thanks!

It might be worth trying a fresh SD card.

Aitor

Hello,

I have not tried to change the micro SD, but it is a bit extrange to have the micro SD card damaged in 4 duet in different machines, no?

In one machine I introduce M122 and this is what appears: "hard fault, spinning module none". This worries me even more, since this one hasn't stopped for a few days.

Any idea or recommendation to try to solve both problems (the stops and the last message)?

Good morning,

I just saw that the command G92 E0 is not responding, could this be what's causing the problem?

@Phaedrux said in Stuck in spin loop, spinning module G-Codes:

It might be worth trying a fresh SD card.

Four SD cards formatted and still stopping.
As soon as I have a new card, I will try it.
Any other ideas or suggestions?

Many thanks in advance!

Phaedrux

Thanks for the additional information and config files. I haven't had a chance to dig into all of them yet. It may be beyond me to give you any resolution. DC42 may have to take a look when he returns next week. In the meantime please continue to report a M122 if it stops again.

This machine hasn't stopped for two days, but it's already stopped

There is an issue when inputs connected to the DueX endstop or GPIO inputs pick up noise. Your config.g file indicates that you are using two DueX5 endstop inputs. Try using shielded cable to connect the switches to those inputs, or add pullup resistors of around 2K between each of those inputs and +3.3V.

Aitor

Hello @dc42,

First of all, thank you so much.
I have made some tests with the changes that you recommend and everything is working well since I changed it.

I have changed the output "duex.e3stop" with "e1stop" , this endstop had 3 wires, but the "duex.e2stop" i have no change anything, this endstop (U axis) only has two wires, GND and "Z STOP" (input E2 STOP). Do you recommend to put the 2k resistance to the "Z STOP" although is not failing?

Thanks a lot again!

dc42

2-wire normally-open endstop switches connected to a DueX are most likely to pick up noise and cause a problem. 2-wire normally closed endstop switches and 3-wire endstop switches connected to DueX would only be likely to pick up noise if they run very close to stepper motor cables for some distance and the cables are not twisted pairs.

Aitor

Hello @dc42,

The endstop that I still have in the duex is a two wire sensor, normally closed. But may be problem if wires go on a chain carrier with the wires of the motor (wires that are not braids), better if I put a 2k resistance to isolate the wires of the endstop?

Thanks again!

Aitor

Hello @dc42,

In the tests that i have done this days, i have seen that the machine did not stop printing as before, but now we have the problem with the endstop that is connected to the duex, sometimes it does not work well:
Sometimes the machine thinks that is always pressed (the axis does not go to home position), others as if it was never pressed (so the motor hits against the endstop but nothing happens).
Is happening in different machines equally assembled. I attached you a picture to show you how I put the 2k resistor. Any idea of what is happening or how to solve it?

I have seen in https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_Num_3:

P"pin_name" Defines the pin name(s) that the endstop(s) for the specified axis are connected to, see Pin Names. Needed when S=1. May need it ! before pin name to invert signal, or ^ to enable the pullup resistor, for example on the Duex expansion board.

M574 U2 S1 P"^duex.e2stop"

Should I be using that way of the PIN output? If I do it, as soon as the machine touches the endstop, it gets blocked and does not recover until it stops touching the endstop. What is this for?

Thanks a lot again!

Phaedrux

Can you try twisting the endstop wires?

Aitor

Good morning,

I don't know what else to try, I've changed the endstop that was connected to the DUEX (U axis) and I put the Z endstop, but it still fails (Now, U axis that is in Duet 2 wifi, works well). This endstop is alone and is not near a motor wire. I tried to put it with a 2k resistor, also with the braided wires, but nothing, sometimes it does not detect it and others it thinks that it is always clicked (so the motor does not go to home position). Is a bit strange because the endstop is a normally closed sistem

Sometimes the limit switch doesn't detect it or it always does, the latter is the most common thing, which makes it stranger to me since it's a normally closed limit switch

What else can I try? Any suggestions?

Many thanks in advance

@Aitor I think your power wiring, both to the Duet and to the Duex, looks very thin. Is it of sufficient gauge to carry the current to supply the heaters, stepper motors and both Duet and Duex electronics? Also, you need a low resistance ground wire between the Duet and Duex to avoid crosstalk and the Duex using the ground wires in the ribbon cable for grounding (which may be causing your issue). So, ideally, use heavier gauge wiring on your power wiring, minimum 18AWG and preferably something bigger like 16 or 14AWG. Use the bootlace ferrules, too. See https://duet3d.dozuki.com/Wiki/Power_Wiring#Section_Main_power and https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features#Section_Wiring

Also, it looks like you wired the 2K resistor in line (is it under your fingers in the shrinkwrap in your earlier picture?) rather than between the endstop input and +3.3V.

Finally, it is not advisable to run wires near the Duet to Duex ribbon cable. The ribbon cable is unshielded, and can pick up interference.
