@elmoret Thank you very much for the offer. I had already seen you and Filastruder help another customer in a bad situation with M3D and was already convinced you guys go above and beyond to help out our community. Hopefully M3D does the right thing and finally sends the promised replacement board but in any case i'm a Filastruder customer from here on out. You folks are awesome thank you!

Allow me to qualify the following. My experience with the Duet2 Maestro is amazing. It is a wonderful product and has exceeded my expectations. I wish to convey my disappointment with M3D's business practice, or carelessness? I'm just really not sure. I cant tell if this is a result of unprofessional carelessness, simple mistake, or trying to pull a fast one.

I received my Duet2 Maestro on 2/16/19 and gleefully started the retrofit on my Ultimaker Original Plus. Somewhere around 3/3/19 I noticed something was not right with fan port 2 when I attempted to use it. Through some simple testing and great support here on the forum I was able to identify the issue as a bad port. I notified M3D of the issue with my credentials. I sent a another request on an alternate support email since there ticket system offers no feedback and on 3/14/19 I was finally contacted by M3D. After some standard back and forth to make sure the issue I had mention was indeed a problem they agreed I should send it in. I wanted to be sure the ordeal was going to be as painless as possible and they assured me it was a 2 to 5 business day process. This seemed reasonable to me so I paid for shipping and sent it via 2 day shipping to cut down time on 3/18/19. As promised M3D contacted me on 3/26/19 and let me know that yes it is indeed faulty and they will be sending me a replacement. "Excellent" I thought then I read the rest of the message. I am to pay for shipping again to have the replacement board sent to me! This is where I started to get a bit irritated. Paying for shipping three times to get a working board is a bit much in my opinion but I wanted issue resolved so I paid and waited. Today 3/29/19 I received the package. The second I removed it from the padded envelope I realized It is the exact same board I originally received and sent for replacement. I went ahead and tested it to be sure. Same issue as before but now there are a few bent pins since it was shipped in a padded envelope with our gentle and understanding US Postal Service.

So after paying for shipping 3 times costing approximately $30us on the same board with no result and a down printer for 2 weeks i'm a bit disappointed with the results and regretting not going with another distributor like Filastruder or Printed Solid. Doing some poking around on the forum it seems in not the only one with issues with M3D but this is a bit much. Its after hours on Friday so I don't expect any response until next week. I have asked them to send me a replacement with 2 day shipping and a return labels as I don't believe I should be paying any more shipping fees to get this resolved.

@phaedrux best typo ever. Giggle meant to be jiggle but my brain took the wheel on that one. I can always try the giggle test.

Giggle test: stare at your printer with intent. Proceed to giggle at it. Record your results. If your printer giggle back call the local law enforcement. or the SCP foundation and let them know SCP-1146 got away.

@siblues Just resolved the issue. Same as yours actually. Found the dupont connector I had used to the board was not seating properly. Used a new one and is working properly. Never thought to giggle test the board connections since in my mind it wasnt a moving part. As the printer vibrated just right it giggle the connector causing the fault.

On to printing!

@dc42
Very good info to know thank you. Ill trace the entire wire and double check all connections to be sure. Based on your information and the image i'm assuming a bad connection that I haven't found yet.

Thank you

Hardware issue: Semitec 104GT thermistor
Board: Duet2 Maestro

Was hoping I could be pointed int the right direction. I noticed my long test print had failed and checked the log. Seems the thermister ran a fault failing to rise to temp in time 3 hours in. I ran another calibration and saved with M500. Babysitting it I found some curious behavior (see attached pic)

I did some digging around here in the fourms and found numerous old posts citing issues from PT100 in terms of interferrence from steppers and such. I don't believe that's whats happening here but I thought it worth asking about. The other more obvious cause could be from bad connection. So I checked this and I show to have continuity on both legs while the gantry is in motion. Also the giggle test. Perhaps there is something else woth testing or another method I could try?

Thank you for your help.

Looks like i'm now in the same situation as @srgallagher13 . M3D is not responsive. Seems they force all communication through a ticket portal that is not managed very well or not checked very often. Took my own advice from the above post but posting here for the benefit of others. Hopefully they will respond before the warranty time ends??

Board has a bad fan output. Shows correct voltage but drops as soon as any load is applied to it. I like the board a lot but darn that's frustrating .

@resam said in Wrong gcode to finish a print?:

G91 only affects the X/Y/Z axis.

You want M83: https://duet3d.dozuki.com/Wiki/Gcode#Section_M83_Set_extruder_to_relative_mode

@resam
(facepalm) that makes things much more clear. Thanks for the assist. Bookmarking that page full of goodness.

I'm going to use the following code and see what happens. Will report back.

M104 S0 ;extruder heater off
M140 S0 ;heated bed heater off
G91 ;relative positioning
G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure
G1 Z+3 E-5 F9000 ;move Z up a bit and retract filament even more
G90 ;absolute positioning
G1 Z204.85 ;move Z to min endstops
G1 X1 Y1 ;move X/Y to min endstops, so the head is out of the way
M84 ;steppers off

@resam
So your saying I should used G91 ;relative positioning then use the G1 E-1 F300? Cause that was originally there but it seemed to go ignored.

So I ran in to a problem with my finish gcode. I basically use the same code in cura but it I belive the new board and firmware interpret it a bit differently than I expected.
At some point during the finishing gcode execution the printer will retract several hundred millimeters of filament. This takes a min to complete then the rest of the code is executed. below is the modified version of Gcode. Originaly it had a line for G91 relative positioning before starting retraction and moving axis but for simplicity I removed it and made sure all the G1 commands used subtraction, addition , or absolute position that is executed from the start code.

I suspect it has something to do with line 3 or 5 but those are subtraction from current position with federate. I must be doing something wrong cause the retraction is happening at the end of every print.

1. M104 S0 ;extruder heater off
2. M140 S0 ;heated bed heater off
3. G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure
4. G1 Z+3 E-5 F9000 ;move Z up a bit and retract filament even more
5. G1 X1 Y1 ;move X/Y to min endstops, so the head is out of the way
6. G1 Z204.85 ;move Z to max
7. M84 ;steppers off

Confirmed. Both problems have been resolved.

Moved the hotend fan to fan jumper 1, removing S0 ,and changing frequency to 25000 then adding blip interval B0.5
Resulting in " M106 P1 F25000 B0.5 T45 H1 "

All working as desired. Thanks for the assists Phaedrux !

was fiddling around and noticed you can snag the stream from Octopi in to DWI. Simply add /webcam/?action=stream to the end of your Octopi address.
example:192.168.123.99/webcam/?action=stream

Config attached.
Printer: Ultimaker Original Plus *Note cause Ultimaker is an odd ball in the motion systems I set this up as Cartesian and reversed a few of the axis.
Board: Duet 2 Maestro v1.0 /with PT100 daughter board v1.1
Firmware: 2.02RC5(RTOS)
Web Int: 1.22.5

Question with issue #1. My hotend fan. Current problem. Its running all the time no matter the temp.

My goal with the hotend fan is common. I wish to have this fan activate to 100% when temperature on the hotend exceeds 45c. The fan is a Noctua NF-A4x10 FLX 3 pin. It is plugged in to fan port 2 using the following config code.

M106 P2 S0 I0 F500 H1 T45

If I understand correctly this states via M106 command that on fan port 2 it will run at 100% at a frequency of 500htz when thermal temp on H1 is above 45c. The probes are PT100 off the PT100 daughter board. They are addressed correctly in the config so I assumed H1 would work no matter what as long as its defend and address properly in M305 and M143.

Question with issue #2. The fan will not start spinning unless I flick it or move the blades my self to get it started. Once started it will run. This printer runs on 24v so the fan outputs are 24v or 5v depending on what the jumper is set to. Unless there is another way around that on the board i'm left with only a few options. Get a 24v fan, get a 5v fan or step down the voltage for a 12v fan. Since I hade a few Polulu 12v 600a step down regulators on hand I used one for the output of fan port 2. Not sure if this has anything to do with my problem but I thought it worth mentioning.

That's about it for now. This is my first 32bit board and im beyond impressed with its capabilities and performance.

Thanks for you help.

No posts about being on vacation and no real holiday that I know of. M3D is more of a retail front and distributor out of Maryland in the US. Sifting through there extensive legal boiler plate they do show to have a 3 month warranty.

To make a claim, please email info@printm3d.com or submit a ticket on our website www.printm3d.com. You must contact us before the end of the coverage period.....

I suppose as long as you have started the process you should be ok on the time aspect. If its a Duet3D product like the Duet 2 Wifi there is a manufacture warranty provided by Duet3D BUT it does state you need to go through the authorized re-seller to process the warranty.

I would suggest continue trying to contact M3D and keep records of your attempts. It this goes nowhere by the 3rd attempt contact Duet3D when they come back from vacation and offer your case details so they can figure out why the re-seller is not fulfilling there obligation and get you taken care of.

Hope that helps.
