Updating firmware.
-
@phaedrux Ok I got it but seems the write up was asking me to update firmware before I was even connected to my network. However the included link to update the firmware required you to have access to the web interface which was confusing.
Now I need help with homing directions on a CoreXY. Both axis need to home to the max position. I got X going the right way but can't figure out how to reverse Y with the tandem motor set up on a core XY -
Well you can update the firmware directly over USB if you wish, but the board comes with functioning firmware from factory so it's usually just easier to connect to the network and use the web interface.
Can you point me specifically to the sections of guide you're referring to? I'll see if I can clear it up a bit.
For CoreXY, check out this setup guide.

The important part is the motor direction test that will tell you how to test and what to change based on the results.

@phaedrux I got most of it figured out and tuning the machine now. One thing im noticing is my travel moves are not as fast as they are set in the slicer. I have travel set to 300mm/s but looks like its only doing about 100mm/s. In the config the xy moves are set to 6000mm/min which should be around 100 when converted right?
-
Increase your max speed in config.g. CoreXY uses two motors together which means one motor may need to move faster than the other to achieve the head speed requested. It's not as straightforward as a cartesian.
-
@phaedrux oK. The 6000mm/min is only 100mm/s right?
-
yes to convert between mm/s and mm/min you either divide or multiply by 60
-
@phaedrux Another thing im trying to figure out is I keep getting a fault when heating the bed. Says its heating slower than expected but for a bed heater its heating up just fine. Can't seem to figure out what to adjust. Currently the bed is set up on Bang Bang
-
PID tune the bed
-
@phaedrux I need to pid tune on Bang Bang? Not very familiar with that method I guess.
Same M303 Gcode used for tuning the hot end? -
@kwad3d Basically the same yes.

@phaedrux Ok. Every other time I installed a duet I got lucky with Ban Bang and didn't have to do it. For some reason on all my duet set ups I have to run hotter temps for my materials to flow correctly. Curious if I have the thermistors set up wrong or something.
-
possibly. What are your thermistor settings? What thermistor do you have?
-
@phaedrux I'm using a standard Cartridge thermistor from E3D. set to option 5 when configured in Marlin. Here is the section from my config.g
; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
M307 H0 B1 S1.00 ; enable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H1 S280 ; set temperature limit for heater 1 to 280C -

@Phaedrux
The part about 'getting started' was written long before DWC was official or even standard. In these days it was common sense to configure your 3D printer HW through USB, but that has changed obviously.@phaedrux said in Updating firmware.:

KUDOs for your patience

E3D thermistors are configured like this, T100000 B4725 C7.06e-8

@rushmere3d Thanks I will try that Thermistor config. Do I just replace everything past Y"thermister" on the M308 line with the info you provided? just double checking before making a change to the config as Im a little rusty on Reprap

You change the B parameter and the C parameter (or add it if it is missing)

Ok that seems to have my temps at normal levels. After pid tuning with M303 I enter M500 and get a Warning about no M501 was executed in config.g. Does that mean the tune did not save?
-
The tune saved, but now you have to add M501 to the end of config.g to load those saved results at boot up.
