Problem with bugs, is you don't know its a bug until you know the root of the problem.
Most all faults are configuration or hardware issues and rarely is it actually a software glitch.
Most new users are going to assume strange machine behavior is a "bug", especially when they are using outdated firmware.
On my 24V 40W heater I had to reduce max PWM to 90% otherwise it will overshoot and fail the auto pid tune.
So I've had this board for a little while on my FT-5 R2, it's working well I'm still fine tuning it.
I notice that I get LaErrors when running M122
It seems to operate fine, but I do seem to get random ribbing at times.
any ideas?

If your building an FT-6 consider a proper 1/4 (or thicker) Mic6 or ATP-5 build plate, the stock beds from folgertech are almost useless without glass- I have a FT-5, also I am in the process of bumping the sticks they call Z rods to proper 12mm ones.
I also highly dislike tethered printing, SD card printing is far more reliable, and with the Duet being able to monitor and adjust stuff on the fly with G-code I see no reason not to just put files on the system SD card, With some prints ranging to 2 3 or even 5 days, that is a lot of time for a single hiccup to ruin your efforts.
Did you by chance hook up the stepper with the duet powered on? even though the duet is protected from such things, it's still advisable not to plug or unplug steppers while powered on.
I've moved axes before powered off and that caused the monitor to blink- I try to refrain from doing this, but it has not harmed my duet, it has never harmed a ramps before either.
I'm curious to see what happened.
After fighting with under/over extrusion issues with my MK10 hotend, I played with coasting, extra prime amounts, retraction speed/distance, I finally used Pressure advance and it essentially fixed the problem.
I found that setting the retraction distance lower than normal and the speed around 50mm/s fixes it, using higher retraction distance caused a little under-extrusion in my case.
I have the advance value at .06, retraction at 1.3mm and speed at 50mm/s.
You can even edit your accelerations, stepper current and more while you are printing- essentially anything and everything, just enter the command in the console.
Also baby stepping for that first layer.
I can't go back to a regular board anymore.
@elmoret
I usually use the continuity test, remove power, place the leads on the fuse, beep! it's good, no beep it dead.
Of course there are always exception in the case of a short circuit that is bypassing a blown fuse- but it's uncommon.
Glad to hear this was protected by a fuse!
Now you aren't done, look over your machine to see if you can find out WHY it blew the fuse in the first place, bare wires, dodgy power supply connections, ect.
Appears it has fixed it, done a few prints, currently have a deceivingly long print wrapping up- only 144gr but takes up the entire bed, 23hrs in 1.5 to go and no LaErrors.
Thanks @dc42 .
looking waaaaaay better than my 1.4 MKS, it had issues with this print as it is a retraction and geometry nightmare- steppers and drivers are barely warm, however I did install heat sinks just because I had them.
Now to build in a web-cam and filiment runout switch, possibly a optical bed level sensor, but I'm new to configuring such a setup, I have a Anycubic delta with a microswitch probe, it works, but that stupid machine will have a stroke and either slam into the bed or print into the air randomly after reboots and require the whole process again.
The Duet isn't cheap and I can see where a clone may be tempting, but, If you are paying $100 already, just fork over the other $60 and get a genuine part that has been tried and tested.
I've been burnt on clones before, and an expensive printer that extrudes expensive material and can easily destroy it'self in a matter of seconds and can start on fire isn't something to cheap out on.
I have noticed with that print, that too high of bed temps can creep up, this makes the material softer and more prone to curling up then squishing out.
Judging by the base, it looks like it's a little too hot, or your layer height is a little too close to the bed.
The ripple you talk of could be over-extrusion, filament variation or Z axis rounding errors or slight binding. What stepper/lead screw do you use?
Also how many shells did you use?
Well I'll be damned.
Prosumer no doubt, they are going to ask a fortune for those things.
(Pause)
M83 ; relative extruder moves
G1 E-10 F3600 ; retract 10mm of filament
G91 ; relative positioning
G1 Z5 F360 ; lift Z by 5mm
G90 ; absolute positioning
G1 X0 Y0 F6000 ; go to X=0 Y=0
(Resume)
G1 R1 X0 Y0 Z5 F6000 ; go to 5mm above position of the last print move
G1 R1 X0 Y0 ; go back to the last print move
M83 ; relative extruder moves
G1 E10 F3600 ; extrude 10mm of filament
That is mine, which should function close to what yours is doing, except I extrude after resume positioning , not before.
What type of printer do you have? is your Z axis binding?
I MIG weld on an off at my job.
As others said, seriously nasty crap comes off of hot metal, there will most likely never be a open source-consumer grade product... ever.
Ever set steel wool on fire? yeah, metal goes up pretty violently in powder or wool form.
I attempted a poly tower, but it ended up poorly because the slicer can only handle even numbers, so I had to print two shells and that kept the heat too close.
Normally I print that model with one shell.
@dc42
Thanks, I will try it out, it's an older unit, but startup is only a split second.
I'm using super thin PEI sheet directly on the ATP-5 plate, but my main concern was EMF getting back to the duet or scrambling up the WiFi signal.
I have a small florescent light tube that would be a perfect fit for my FT-5, I could easily hook it into the mains just like I did the PSU muffin fan.
I understand this lighting can throw off the IR sensor (I don't have/ need one) and they can throw off some EMF.
Has anyone used one of these, if so did it cause any issues? the whole frame is grounded through the PSU due to it's ACM/alloy construction.
Holy crap 9K? Such a shame they used a inferior board for a commercial grade machine that weighs 275lbs.
I really like the belt mechanisms in that thing,
Basic cuboid Cartesians are nice because they are very simple and accurate, especially when you have a huge steel box to mount the axes to.
Oh yeah, It's bigger than I thought!
The steppers in there look teeny tiny!
