Duex5 Endstop Issue
-
I recently moved my U-axis endstop to the duex5 so I could add two filament runout sensors on my IDEX when I started to get intermittent crashes while homing the Y-axis which was actually do to the U axis not homing correctly before the Y. Its happens about every 5-20 times its homed.
When I move the U axis endstop from the Duex5 to the WIFI the U axis homes properly and I no longer get the crash while homing Y. Why am I only having this issue with the endstop on the Duex5 but not on the WIFI?

Hi,
What version of firmware are you running?
Frederick

Oh sorry I missed that somehow. I was running 3.2 but I had a lot of issues happen at around the time of install that I thought were related so I rolled back to 3.1.1 and recently completely erased and reinstalled 3.1.1.

Firmware 3.2.0 has some issues with endstop handling causing it to miss one on occasion.
Firmware 3.2.2 fixed that problem.

@fcwilt Ok, I've had a few other issues as well when installing 3.2 but when I reverted the other issues are still there as well.

Well the problem you describe was characteristic of firmware 3.2.0 - I never experienced it with 3.1.1 nor with 3.2.0.
I would suggest you upgrade to 3.2.2 and see if it makes a difference.
What is axis U used for?
Frederick
-
@fcwilt Its a IDEX so T1 is U axis and T0 is the X axis.
It homes X and U first then moves them away from the endstops. Next it homes Y to two different endstop switches to square up the gantry. There is a Y axis motor at each end of the gantry. If the U axis is not moved away from the endstop, while homing the Y it will pull the U axis towards the endstop because of the way the Dual markforged kinematics work.
It was hard to debug because it looked like a issue with the Y axis homing but it was actually the U axis, it just does not cause a Issue until it gets to the Y axis homing.

Can you post a diagram of the motion system as used on your printer?
Thanks.

@fcwilt The Kinematics are correct, not really in question.
M669 K0 Y1:1:0:1.Its a 0:1 or 1:0 arrangement depending on direction of travel of the Y axis.
The issue is the U axis is not stopping at the endstop correctly when connected to the duex5. I dont think the type of kinematics plays a role. Perhaps I gave TMI.

You only need singular values for linear axis in M350, M566, M201, M203, M906, etc. It's only extruders that require those values to be defined per drive. Once the driver has been assigned to an axis, you only need to define the settings per axis.
3.2.2 did fix some issues with endstops triggering very close together. So updating to 3.2.2 would be a good thing to test.
Also something to keep in mind with the duex is that it's usually a good idea to try and keep the Z axis motors and endstops together on the same board, probably the main board. So in your case you could have Y and Z on the mainboard and X U E on the duex. That may help avoid any timing issues.
This may also help with your other thread on independent Z leveling.

This was pointed out in in the last thread. I made some large changes in experimentation and I must have reverted back to multiple values. I'll change it back but I have already confirmed that it will not have an effect. I'm assuming it defaults to the first value given.
It does seem like a good idea to put the endstops on the same board as the driver, but I was just trying to keep the X, Y, and U drivers on the same board. If that does not matter, I will move the U axis stepper and endstop back to the WIFI and then move both Y axis motors and endstops to the deux5.
Can you confirm that its ok to split drivers that work in conjunction to together on different boards? I would like to move the filament runout sensors to the deux5 but the documentation says it will not work. If its not suggested, then dual filament sensors would not be supported with my setup as I don't see a way around it.
I guess I will try 3.2.2 to see what happens.

@3DPrintingWorld said in Duex5 Endstop Issue:

Better to split X Y U than to split the drivers between a single axis, no?
Personally I would use the probe for leveling and abandon multiple endstops entirely.
-
@Phaedrux I am only using the probe to level Z. The other stepper motors each have a endstop; X, U, Y(left), Y(right). Four in total. I do use two endstops for the Y, that is required to square the gantry to the frame.
I have considered sensorless homing for the Y, which would free up to two spots on the WIFI. Another user in our group has had good luck with it.
-
Ah yes, sorry, for some reason I took your other thread about independent z leveling as the reason you were wanting to use multiple endstops.
Sensorless homing may be a good option. It might take some tuning though.
-
Something that just came to me.
I think a year ago during setting duex5 with my dual lifting extruder experiment in the documentation was stated to take power for the duex from the duetwifi terminal , not directly from PSU. I forgot about that when wiring Muldex and the power for duex comes from PSU, i think others did the same as far the wiring on the github scheme is like that. I wonder if that could be the reason. I do not belive so.link textThe only reason for some troubles could be having bad GND conection between 2 boards
-
Hi,
This is how I connect power to Duet 2/Duex combos.
The two wires connecting the boards are solid, the two wires from the power supply are stranded.
The goal was to keep the length of wire from each board to the power supply the same so both boards see the same voltage.
Frederick

I had a very similar issue when building my IDEX printer. I seem to remember finding information from @dc42 that the end-stops on the Duex2/5 were polled differently from those on the main Duet2 board. I just moved mine back to the main board and the issue went away.
The issue I had was caused by the end-stop status not changing correctly or becoming stuck as triggered when it wasn't. This caused failed homing on the U axis, or failure to do a second more precise homing move after the coarse one. I verified that it was the Duex by manually triggering the end-stop and monitoring its status in DWC, where you could see it sticking. As soon as I moved it to the Duet2, it worked flawlessly.
-
So with Muldex that can sol e the U problem, but with 3 Z motors on duex and Bltouch on duetwifi?

@martin7404 Good catch! I remember seeing that too, but I must have spaced it when I did the wiring. The wires are about 100mm long so it might be ok but I'll change it anyways.
-
@NexxCat This sounds like the issue. I updated to 3.2.2 and homed it maybe 10 times and no problem so far but it can be intermittent. I test it some more today.
I would move it back to the WIFI but I was hoping to use two filament runout sensors so I don't have the room on the board for both if I do.
