Duet WIFI Random Skipping Issue
-
OK I've had this issue on 2 of my printers (installed the duet on both printers to test it's not a fault with the machines)
About 33% of the time this is what happens when I power up my machine. https://photos.app.goo.gl/JSx6ikmvSesdLJMU2
As you can hear, it is skipping like crazy. This happens on both X & Y.
If I reset the machine several times, it happily prints for several days.
Any ideas, are the pin headers on the board faulty?
-
Sounds just like my z axis driver, it has no torque at all. Putting the z axis motor on any other driver its smooth and quite.
Hope you get it resolved. -
Which firmware version are you using? Have you tried version 1.20RC1 ?
-
Still running 1.19, is there anything specific in 1.20RC1 that could address the issue?
-
You should be running at least version 1.19.2 which addresses bugs in 1.19, one of which might possibly account for the strange behaviour. If you are using our MAX31856 thermocouple daughter board, there is another relevant fix in 1.20. In any case, with 1.20 close to release I won't be doing any investigations into possible bugs in earlier series firmware.

Thanks, i'll update later today and report back if I still get this issue
-
Totalitarian,have you found anything?
My new Duet has been like it since it's been hooked up. Intermittent working, occasionally it drives correctly although I find it doesn't last and will change to this weird crunching after some time.
-
I've changed the loom
-
I've changed the NEMA17 motor it is hooked up to by testing it against my 2 year old (working) Ormerod 2's X-axis (with Duet 0.65 running firmware 1.19)
-
as well I plugged it into the Y-axis on this Ormerod 2 - same symptoms.
Today I was demonstrating to a friend and he pointed out to me that to him, it looked like it might be heat related, as it works from a "cold" state (not been switched on recently) but doesn't work after it's been on a while.
We then did further tests by pointing a big household fan at the board when switching it on from cold.Many (unscientific) repeats seem to show that it works a lot longer when a fan is pointing at it, as well as failing after a couple of minutes when the fan is removed.

This is immediately afterwards, after switching off and swapping the X and Y axis cables on the Duet (and nothing else). This shows the X-axis working and the Y-axis crunching https://photos.app.goo.gl/DOma7r8vhHJ3bs5x1
For information, I was running Firmware 1.19.2, and just in case I upgraded to Firmware Version: 1.20RC4 (2017-12-20) as indicated above, with no change to the behaviour.

(it is mounted in the open, so there is no airflow issue) or is this something I should be contacting Duet3D about?

I've just replied to your similar post on the RepRapForum. If you suspect that a particular motor output his at fault, try substituting the E1 motor output instead, and use the M584 command to assign the E1 driver (driver 4) to the axis concerned. The M584 command must come before some other commands including M906 and M350.

cheeseandham doing as dc42 mentioned fixed the issue for me. It must be a faulty driver. dc42 how do we go about getting it replaced under warranty?
-
Email your supplier. If you bought it from duet3d.com then the address is info at duet3d dot com.

Right, now Christmas is out of the way!
I used the M584 command to assign the E1 driver (driver 4) to the X axis as instructed above.
Everything works fine and I commissioned and could print a Marvin.Moving the loom back to the X axis, and unfortunately it does the same thing as before (works for 0-4 minutes then crunch & fail)
I wouldn't mind so much if I hadn't bought the DuetWifi specifically for dual extrusion
Therefore I'll report this to my supplier.
-
Sorted out / solved.
I'll just say Think3DPrint3D have great customer service.
