Duet Wifi setup - need help
-
Thank you, elmoret. I know it's not recommended to print via USB but I kind of like it. Seems easiest for me. Maybe I can learn to do it another way.
-
Well crap, I figured out why the nozzle wasn't heating up! I clicked on the Heater 1 in the web interface and it went from standby to active. What purpose does this serve, aside from challenging newbies?
-
Latest issue…extruder motor was running the wrong way. Changed M569 P3 S1 to M569 P3S0. This worked to reverse a different motor earlier today. Now, in the web interface, I cannot get the extruder motor to turn and get this error message:
M120
M83
G1 E-5 F600
M121
Attempting to extrude with no tool selected.So...what the heck did I do wrong now?
-
There are two heaters in the web interface because some printers have two extruders.
If you changed it to "M569 P3S0", the problem is not having a space between 3 and S.
Also, if you flip the connector on a stepper motor, it will reverse motor direction.
-
Oops, that was a typo…there is a space between the 3 and S. The funny thing is I changed it back to how it was originally (when the motor was working, just running backwards) and it still doesn't work. I've powered down, refreshed the web interface, and still doesn't work.
-
Could you post your config.g here, please?
-
There should be a line like:
M563 P0 D0 H1 ; Define tool 0 to use extruder drive 0 and heater 1
-
Also regarding the power from USB question:
Specifically, the board can always safely be powered by USB

I just noticed this line in my config.g:
M350 X16 X16 X16 X16 I0 ; Configure microstepping without interpolationShouldn't it be M350 X16 Y16 Z16 E16?
Would I want with or without interpolation?BTW, this config.g is from the configurator. I was reading about it in another thread and it seems this happened to someone else.

From the Wiki:
"The 5V circuit can be supplied from USB (for example, with no actual PSU attached; recommended for initial setup), an external 5V supply (for example, the +5VSB rail on an ATX power supply), or it can be powered from the 12/24V supply through an internal switching power supply. Jumpers must be set up appropriately. Specifically, the board can always safely be powered by USB, but if the INT 5V EN jumper is set, the internal switching-mode power supply will feed the 5V circuit from the 12/24V circuit; if instead the EXT 5V EN jumper is set, the board will be powered from the 5V in pin."
The bold text is where I got confused. It sounds like, as you said, you can always safely connect the USB cable. That makes sense as there could be numerous instances where you'd want to do that. Reading it again, and hearing your advice, makes me feel comfortable connecting the USB with 12v power applied to the board.
Thanks! -
The I0 or I1 is to turn off or on interpolation. Turning it on should result in smoother/quieter printing. It shouldn't cause any problems. I use it on "I1".
You need a T0 at the very end of that config.g file. Perhaps that got cut off when you were editing?
-
The only thing I changed is the 1 after the S…changed it to 0. Then the extruder motor would no longer turn (it would turn before, just going the wrong way). I even changed the 0 back to a 1 and the motor still doesn't turn. Very strange as the config.g is exactly like it was before when the motor was working.
-
T0? Ah…I see that on the config.g file that came default on the SD card...it's not on the config.g file that the configurator spit out. Let me try adding it...
-
Okay, tried it with the T0 at the end and discovered something…it gave me an error message saying you can't extrude because the hotend wasn't up to temperature! Ah, this thing is far smarter than me! I did try turning on the heater to make sure it worked and that must have been when the motor would turn. So the error message that says no tool selected is because the Heater 1 thing somehow gets set to standby...that's what the message means...make the Heater 1 active.
I removed the T0 and it seems to still work the same. What does the T0 mean?
-
Great! I think it's mostly functional now! Next up is the IR sensor…
-
T0 sets the active tool (extruder) as tool/extruder 0.
-
Thanks, Tim. I put the T0 command back in. Got the IR sensor hooked up and functioning. Just need to do the final adjustment/calibration process.
How can I use the original Z-axis limit switch as well as the IR sensor? Reason being, if I home the machine, the IR sensor will be off the edge of the bed. Some mechanical modifications I made to the machine cause this, namely the addition of an E3D V6 extruder and glass plate over the stock aluminum heated bed. So, for bed leveling, I can move the test spots to a good location, away from the edges, but then still need the Z-axis limit switch so I don't crash.
-
In yor homez.g and homeall.g files, before the G30 command to home Z, use a G1 command to move the head to the centre of the bed. Or you can use your microswitch for Z homing if you prefer. See https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer#Homing_files.
-
What does this mean?
G28 X
Triangle interpolation: point outside all triangles!I get this message when homing any axis. I've been messing around with the bed.g file and and auto bed compensation and it seems to have started shortly after this.
