Duet not extruding on x axis and panel due has no screen
-
Like David, I saw the one video file. From your description, it's sounding like you have a bad connection on your extruder stepper motor wiring.
-
I have to go to work in a little bit but when I get home I will run a new stepped motor wire straight from the extruder to the duet bypassing the cable chain and see if it changes I have two extra connectors and extra pins from the original parts when I got the duet
-
Ok so I got home from work and completely removed the motor except for the extruder gear and ran a new jumper from the duet to the motor and it appeared to fix the issues as the gear seemed to run smooth so I guess I'm gonna delete my cable chain altogether because I'm assuming it pinched one of the coil wires I do really appreciate y'alls time helping me with my issue I know y'all are busy people and have always answered my questions super fast I constantly recommend this board to people on the forums I belong too and not just the product but your service behind it but one last question is it possible to run 2 wifi boards or would it be better to run the Ethernet version on the other I'm building a new build it's a long way off from electronics yet but I want to use a duet board on it ?
-
It is no problem to run two Duet Wifi boards on the same network, or one Wifi and one Ethernet. Or two Ethernets even.
-
The problem with your cable chain probably isn't that the wire is being pinched, it's probably a poor crimp connection at one end, that does or doesn't make contact depending on which way the wire is pulled.
If you put two or more Duets on the same network, they must all have different MAC addresses. The WiFi does this automatically. For the Ethernet you need to use the M540 command in config.g to change all but one of them from the default.
-
Glad you got it fixed and yes, as David pointed out, don't give up on the cable chain. It's most unlikely that all the strands of the wire broke somewhere in the middle of the run, but much more likely that it was poor connection at one end.
-
Actually I believe I spoke too soon I started everything back up was trying to make sure everything homed and moves like it should and it did then I shut everything down to make sure the bed was still level I fired it back up and the x motor started skipping back and fourth across the rail wildly and no extruder again so I'm at a loss I know all the pins are good I checked them tried swapping motor wires with the y axis cause it seemed ok and tried to move the x again it started jumping around again I have no Idea where to even start now cause it acts perfect then it freaks out and starts weirdness I've tried fighting with it since about 8 pm it's now 3:44 am and it act fine then something will act up sorry for the the trouble but I've ohm'd wires checked connections checked voltages and schematics and it will do what I ask it then I try to repeat and it goes nuts for some reason
-
Intermittent faults are always a pain. You haven't mentioned your Panel Due since the first post. Is that working as it should or do you still have problems with that too?
-
No the panel due still no screen but I can hear the sound of the buttons being pressed when I touch the screen and the fault isn't internment anymore I tried using the motor cable from one of the z axis motors to the x motor cause I know the z axis moves like it should and nothing anymore x or e motors you can feel them get there holding tourqe but no movement at all I tried using the x motor cable on the z axis to see if it did the same and it moves like it should just fine same with y axis motors
-
I've tested a little more and the x axis will move now dont know why its the same motor wire from the y i was testing it with i have the motor out just sitting on the machine same with the e didn't but nothing on e still at all no matter what can't even feel the motor engage to hold it in place
-
It's very difficult to diagnose from a distance. I'm wondering if it's a power supply issue. Maybe it's only just able to supply a small amount of power so that when you try to drive one or more motors, the voltage drops. Are you able to measure the voltage at the input terminals of the Duet? Preferably when you try to drive a motor. Also, after you've tried to move the extruder and X axis motor, could you run M122 and post the results of the diagnostics. I, or more likely David, might be able to spot something in that.
-
Ok will will measure the terminal voltages and run the M122 command and post the findings to you I will have to do it in just a little bit as I have to finish up an animation so I don't get behind on it but I will do it as soon as possible again thank you
-
ok i finished my work and started back looking at the printer i found the problem with the x motor is the cheap cable wire that was supplied with the printer i made a new one with some better wire like i did for the e motor and its working fine again so i ordered quality wire for all the motors (it kinks if you look at it worng) as that too is going to get replaced immediately so that issue is solved wire will be here monday. as for the e motor even with a new cable i get nothing i also remapped to the e1 driver and still got nothing tested with 2 different cables and 2 different motors on both drives same results with both test. i checked the voltage at the duet terminals and it was at 11.99v so the voltage looks good and this was what i got when i ran the M122 command

Ok I did get e1 to work for some reason it didn't assign the number in the config g file when I gave the command so I went back and tested both e0 and e1 and e1 works as should e0 nothing but it's still strange because from my understanding of the m122 command it didn't show any fault at least that I read in it
-
It looks like you are making progress. Also, I couldn't see anything amiss with the result of M122 (but David might spot something that I haven't - no doubt he will step in if he does see anything amiss). So it's looking like all your issues are down to poor cables or connections. As for the E motor, maybe it's a bad motor? Try swapping it with one that you know works consistently. That will prove it one way or another.
-
Yeah I worked out all the other issues mainly cheap Chinese wire but that's going to be fixed and I tried getting the e0 to work but no dice it's printing at the moment on the e1 port I could never get the e0 going
-
And I never got the panel due up either but filastuder said they would replace the panel due and the LCD I checked the wires on that one and they are fine (I'm using the premade wire lead that was optional ) so that will be fixed as well so everything seems good just that e0 but I only use one extruder
-
As I said, try swapping the E motors around. That will prove if it's a bad motor.
-
I did on two different motors when I started having the extrusion issue I purchased two new motors one as a replacement and one just for a spare I've tried all 3 motors and it will not move any of them and they all work on the e1 port I removed the board from the printer and checked to see if there were any wire strands resting on it but it's clean it's mounted to a melamine board with small deriln plastic standoffs I inspected the board for any noticeable marks scratches or burn spots and it appears to be clean I rechecked all motors after I mounted up the board again and replugged everything back up to the duet and again all three motors operate on e1 and not on e0
-
Please share your config.g file and tell us how you are trying to move a motor attached to the E0 motor output.
