@CaLviNx seriously stop commenting. I do beta testing and bug fixing for a living. I took the steps I did for a reason. Everyone else has been trying to help while all you've been doing is throwing jabs in and out of this thread. I don't need you to tell me what the "smart approach" is because "the whole point of the exercise" is to figure out what happened and to see if I could fix it, not applying a band-aid.

@oliof in the end it was solved by reflashing the firmware with bossa. He was using a 10 foot cable. Told him to use a shorter USB cable and it worked.

@ratrig0331 It tells you what pin on the accelerometer plugs into what pin on the Duet 3 Mini.

@deonholt actually that's my mistake.
M566: Set allowable instantaneous speed change

M205 is an alternative to M566 for compatibility with Marlin.
Open your config.g file through your web browser. and make the changes there. Don't use M500.

I used Marlin for years before switching to Duet. It's a bit of a learning curve but once you get used to it it's easier and more convenient doing it through your browser.

As far as order goes look in the Gcode page i linked previously. If there's conditions as to where the code must be it'll say in the description. Personally I have my configs setup with each gcode relating to each other entered together

@fcwilt Agreed. I planned to incorporate it in my build and was disappointed when I couldn't use it. However after enough tweaking I think I'm in a better place. Upgrading to the PTFE coated leadscrews helped quite a bit. I also figured out the leadscrew offsets were slightly off. Once I changed the config results started to improve. Even more so after using 4 points to calculate the leadscrew offset. This was my last G32 without the spring steel sheet on.

You should post this on the Facebook page as their's more users familiar with the BLV Cube and the creator of the sketch is on there as well.

After homing manually jog the nozzle to your first probe point. It should be the farthest point along X min the probe can reach and note the coordinates. That's where P0 would be. Jog to the fathest side on X max the probe can reach and that would be P1. With 2 steppers Y doesn't matter but X does.

M671 is the actual positions of the leadscrews. the 1st point will be negative because it's outside of the print area. But make sure the first coordinate in M671 is the stepper motor that is wired to the board in Z0.1

This is my bed.g file that gets called when running G32
I have 3 independent lead screws whish is why I have P0-P2.
M557 defines the probing boundary and P4 probes 4 points on X and Y so 16 total.
It homes, probes each point and adjusts for compensation. It repeats that 3 times than does the actual bed leveling probing.

@jay_s_uk Go figure I completely forgot to change that. That worked thanks.

I connected the 2 ground wires together and it's been fine

I know there are other slicers that have different features that may or may not be better than S3D. I've tried other slicers and I don't like them. I've used S3D for years and there's no reason for me to switch.

@droftarts Genius. That fixed the problem. Thanks!

Setting up my Duet 3 Mini 5+ with RRF 3.5.4, DWC 3.5.4 and Wi-Fi server 2.2.0, no SBC. I'm sure something is wrong with the config but I'm not sure what.

I receive the following error:

M98 P"config.g"
Error: exactly one of EFHJPSR must be given
Error: unconfigured spindle
Error: in file macro line 52: M568: Invalid tool number

I used the configurator to build the config file.

@Phaedrux Sunday afternoona

I've been trying to get a Bluetooth controller connected the my RPI 4 in SBC mode controlling my Duet 3. It occurred to me it might be disabled. When I go to the Bluetooth Manager I receive the error:

I'm not sure what I'm missing but I've already update the pi and the firmware.

I know there are other slicers that have different features that may or may not be better than S3D. I've tried other slicers and I don't like them. I've used S3D for years and there's no reason for me to switch.

@dc42 With post processing scripts you can still use G10/G11. I set mine up like this

{REPLACE "G1 E-0.5000 F4500\n" "G10\n"}
{REPLACE "G1 E0.0000 F4500\n" "G11\n"}

@chrishamm Wow really? You'd think it would be... Thanks for letting me know.

S3D has a feature where you can send the file and start printing after you slice it but I'm having issues getting it connected.

This is the instructions on the page:

Most network-enabled 3D printers support auto-discovery, meaning that the software can automatically detect the printer on the network and determine the appropriate connection details. To test this process, go to Tools > Machine Control Panel within Simplify3D and click “Add New” to launch the New Connection Wizard. Select the “Network Connection” protocol, choose the “Search for Connections” option, and then click “Search for Devices” to begin the auto-discovery process. Note that this process will only work if your firewall and network rules allow UDP traffic back between the printer and your computer. In many cases, you will need to add a firewall exception to allow Simplify3D to detect the 3D printer.

If the software cannot find your 3D printer, you can still enter the connection details manually. Select the “Manual Connection Details” option and then enter the IP address for your 3D printer. This information can typically be found using the LCD screen on the 3D printer to browse to the info or network status page. The software can typically select the correct port automatically based on your printer profile, but you can also enter the port number manually if needed. Common port values used by different manufacturers are listed below:

FlashForge: port 8899
Ultimaker: port 80
MakerBot: port 9999
Dremel: port 80
Qidi Technology: port 3000
XYZprinting: port 9100
Once you have entered the correct details, you can click Next and press “Begin Connection Test” to establish a connection with the printer. If the software fails to connect, it typically means that the firewall or network settings are still blocking the connection. Make sure a firewall exception has been properly configured and consult your network IT manager to make sure traffic between the printer and your computer is permitted. Once a connection is successfully established, Simplify3D will automatically save the correct settings for the future, so you only need to perform this setup process once.

While trying to connect I enter my printers IP and for port number I select automatic but it fails.

@jay_s_uk Go figure I completely forgot to change that. That worked thanks.

My setup is:
Duet 3
Duet tool board
RPI 4B
Firmware updated to RRF3.4.2

I just purchased a Slice Engineering RTD PT1000 thermistor. My thermistor config is:

M308 S0 P"0.temp0" Y"thermistor" A"Bed" T100000 B4725 C0.0000000706
M308 S1 P"20.temp0" Y"thermistor" A"Hotend" T100000 B3950

My hot end temp is showing 179.9c where my bed is showing 23.9c. I've tried B4725 and B3950. What should the configuration be for?
