@o_lampe assuming that you don't have a DueX connected to the Duet, RRF will know that they are not TMC2660 drivers. Just configure the microsteps/mm value in M92.

@gixxerfast Brilliant!! I didn't notice the jumpers!!

@timtom you will need to fill in the form anyway so that we can contact Filafarm and authorise them to replace your board. Yes Brexit is a horrible mess and makes things difficult, so we will arrange for Filafarm to provide the replacement.

@modix2021 WiFi disconnect screen shot.png

We thought that since the wifi was connecting when the Modix was turned on, everything was fine. Wrong. After some minutes of printing, the disconnect/connect behavior begins again. See screen shot. I have a new board sent b y Modix, so we will put that in next week. The adventure continues.

@chazrogers each tool has configurable offsets
https://duet3d.dozuki.com/Wiki/G10#Section_G10_Set_workplace_coordinate_offset_or_tool_offset

This allows you to have (say) 1 tool at 0,0 on XY and then another tool with a different offset when its picked up by a toolchanger. these offsets are applied as described in the documentation you quoted.

@j3d the reason is that we want file uploads to be as fast as possible, and SD cards prefer large block writes; so RRF uses a 8K write buffer. In contrast, it's rare to download files from the Duet, and other file reads from the SD card don't need large blocks of data in one go; so RRF uses much smaller read buffers.

@mikeabuilder said in All All SD card data lost after web estop:

none of the files on the SD card are ever changed by the fw

there are some files which are changed:
config-override.g <- every time you send M500
heighmap.csv <- every time you probe the bed and save the height map
*.json within the /sys directory <- various DWC and plugin settings that can change

The firmware binaries and other /sys macros are not changed by the printer. and in the case of the /www directory and firmware binaries, those are on github to download again.

@marshal

GREAT!

I'm glad you're running again.

do you know if i have to configure something in davids ino file from github ?

@kolompos said in Duet 3 6CHMB keeps crashing:

@droftarts Yes but there are also 3A diodes on board.

Yes, sorry, documentation error, fixing!

@PCR updated the wiring diagram image.

i used the input shaper plugging and tried zvd from .1 to .6 at 136 hz and none made it better. see below

whats interesting is that when i use the plugin, when it moves in hte y axis, it appears to be trying to move at 1000mm/s and the y motor skips a lot of steps. my max speed in firmware is 300mm/s and i know its trying to go faster than that.

also, i know the m953 command is working as when i turn it on and send the below command the travel is super weird if i have the smoothing at .99.

G1 X-50 G4 S2 G1 X50 F20000 M400 M956 P0 S1000 A0

maybe these are just modes i can't get rid of? i do think that a majority of the vibration the accelerometer is seeing is the physical shaking of the whole printer. the printer itself shakes and is not on the best of surfaces so thats a thing. if this algorithm doesnt cancel out that type of movement maybe that could be put into the wiki?

@fcwilt Thank you. That worked. But I almost got a heart attack. I Checked the connection, checked it again, then checked the connection. I flipped the switch and I heard a strange sound! It was just my arm had snagged the curtin and it popped on the rod.

Anyway, it worked. Thank you

@modix2021 said in Lines on LCD:

@t3p3tony
Modix is sending one. Any idea why my wifi and LCD would mess up at the same time? Then wifi came back whether or not the faulty LCD was connected. Hoping to learn how to keep this from happening again. Will have been down for a month sorting this out.
You have been most helpful when I post.

Likely that the Duet and PanelDue were damaged at the same time from shorting 24v to 3.3v or 5v.

@t3p3tony thanks alot for your inputs brother..

@pcnoobneedsmajorhelp, power down your printer and disconnect your thermistor then check its resistance against the manufacturers specs then also check for shorts/breaks in the wiring 🙂

@dogma2k that connection is external 5V input only. Also the USB port is for 5V input only.

There is a 5V output on v1.01 and earlier MB6HCs: https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Hardware_Overview#Section_5V
Designed to power a SBC like a raspberry pi.

Be sure that the AP won't overload it, even at startup. Generally we would recommend powering external devices from there own power supply.

@gallaghersart I have done it, you first mark as question, then as solved.

@jphilly it would be better to put the SPI daughter board on a riser, because if the drivers are on a riser then the high ground currents when the motors are driven could cause noise issues.

I avoid Chinese power supplies not because it can damage my duet but because it can damage me, my family, and our home.

If Meanwell (Taiwan) or other reputable manufacturers choose to manufacture in China, but own the process, spec, and certification it's fine with me.

Edit: for high quality Meanwell PSUs, I recommend the UHP series. They are compact, highly efficient, stay cool, and are fanless.
