Hello, am new here but not a newbie as such.

FuseDeep

In general, going OK, am fully rehashing the XY gantry with open beam. Nice and simple meccano for grown ups. Enjoying belting up too, combining GT2 on a nema 17 and GT3 on both sides of X.

Looks like it will be 2x Nema 23 for X and 1x NEMA17 for Y so will be looking to run 2 Nema 23 at full power from either the same signal (one reversed) or use two Duet outputs, one reversed.

Have not even started to look at a DUET file yet. IS there an example file of a fairly normal Cartesian set up file I can start to get my head round please?

Also need to look at links above in relation to the basics. will do.

Cheers R

Use the configuration tool at https://configtool.reprapfirmware.org/Start to get you started. Read https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinte when you want to understand what the file contents mean.

There is a suggestion running 2 stepper in series (but one reversed?) is best for the Z set up. I assume I could reassign Z to my X and use the twin set up?

I think the Duet wifi does not have a spare stepper output other than the twin Z. So I could mirror the 2 X axis stepper motors.

FuseDeep

Where is the idiots guide to DUET set up please?

For example I am not sure how or what the SD card is meant to be connected to to configure (wifi or in my laptop) . Do I have to be connected to the wife of the board to do the config?

Plus, I have 2 SD cards as one with the screen. The board based one is key as I understand it.

It'll make sense once I have don it...but have never done a DUET.

Bit at a loss currently. I do get the impression I might be a stepper driver short on Duet wifi, running two on X (as opposed to Z)

A lot of the interaction with the Duet is through the web control interface. The documentation for that is here: https://duet3d.dozuki.com/Wiki/Duet_Web_Control_Manual

The Duet Wifi would typically be connected to a wifi network, and then you would connect to the Duet through the web interface in your browser. Alternatively, the Duet can be configured to create its own wifi network, which you could then connect to.

A lot of the basics of getting started can be found here: https://duet3d.dozuki.com/Wiki/Step_by_step_guide

The SD card that comes with the board will have a very basic default configuration used for testing at the factory. You'll need to provide a set of configuration files specific to your printer. This would normally be created with the online configuration tool. https://configtool.reprapfirmware.org/Start

This would provide a basic configuration. More advanced configuration of specific features would then need to be completed manually by editing the configuration files.

If you're already connected to the board over the network and have access to the web control you can upload the resulting config set and edit the configuration files right there in the browser, or you can use your PC to edit them and put them on the SD card first.

The SD card slot on the board itself would typically hold your configuration files and where the uploaded gcode files would go. The SD card slot on the PanelDue is accessible when the PanelDue is connected via the 10-pin ribbon cable and it can be used to load gcode files in the traditional manner of placing the sliced gcode file on the SD card using a PC and then physically transferring the SD card into the PanelDue slot. You'd then use the web interface or the PanelDue to locate your gcode file for printing.

The Za and Zb drivers are wired in series and are not individually addressable since it's a single driver. There are 2 separate extruder drivers, so if you only need one extruder, you can use the other extruder driver as another X/Y/Z axis driver.

@Phaedrux Awesome thanks. I'll work through this as things progress. Thanks again.

Phaedrux

No problem. The duet and reprap firmware are a little different than you might be used to and it will be a learning curve. We'll be glad to answer any questions you may have.

FuseDeep

@Phaedrux Appreciate that. It might have been too late in the evening to start looking at it last night, hence the gripe. Apologies.

Getting the gantry built then get serious end of the week with code/DUET. I'll try and go through the steps more constructively. I'll also ask my DUET experienced buddy locally to dive in, will save many questions no doubt.

FuseDeep

OK, @FuseDeep fully re built. Next step, mount DUET board and screen for initial wire up then start firmware settings...

What is the simplest way to contra rotate two stepper motors on one axis please? How do I assign a spare E (extruder) axis to be the second X?

Probably start initial firmware settings tomorrow afternoon or Monday. Images to follow.

Danal

Do build an initial config with the online tool: https://configtool.reprapfirmware.org/Start

Do expect to tweak that.

To your question about multiple motors, see: https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors

It is intended for multiple Z, but it is not too hard to see how to do multiple on any axis from the examples.

FuseDeep

Thanks, again:

Updates, last few days entirely new XY gantry , cable guide chain, filament distribution and extruder set up, with 3 fan initial layout that needs testing (and is too wide)!

Ps:

Thanks again @Danal , will look at board hook up today and then start config etc

FuseDeep

@Danal Cool, is there a simple command to reverse one of the axis steppers if 2 are used? So they contra rotate. EDIT: Or I just reverse wire the second stepper from the spare output. simpler.

deckingman

@FuseDeep Simpler still - to reverse a motor direction change the "S" parameter in M569.

FuseDeep

Hmm. Have run

M552 S2

and it seems to show a network I can connect to. This was a bit flaky to begin with but shows up now. Does this get saved by the M589 set up command I assume?

For no apparent reason it suddenly started showing error filename too long and a long web address. Have not done anything so no idea why...we'll see.

Time to start wiring it up with the power off. obviously.

BTW, could not work out where the latest firmware link button is on github, once on that page.

wiring up then make a basic start

OK, stuck:

Board says wifi idle. Have no idea what to put in as M587 command. wasn't it meant to be an adhoc option, I have no router hub?

Literally can't find instructions as to what my IP address should/might be in the DUET or how to set up as adhoc. Some help needed, please.

R

Access point mode is configured via M589. You'll define the SSID, the IP address, etc.
