3DP1000 Duet Ethernet Conversion

Cherno Alpha

The Duet Ethernet should be here tomorrow.
A few other items I will be doing to the printer is an enclosure for the print area. Pretty important for me as I do a lot of ABS printing (helps I make my own filament as well).
The next is the Z-Probe for mapping the bed. I had a look on this site and saw the Piezo sensors. They look to be pretty much perfect for my purposes. Mapping the 1m x 1m bed is pretty important especially if there is dips in the bed. Any one used the piezo sensors? They are mentioned on this page here. https://duet3d.dozuki.com/Wiki/Choosing_a_Z_probe . Once that or similar is installed, I will probably do 15 points on the bed to map it out. Essentially one measurement every 25cm.

beware if you'll be using the online configurator with power loss function

@bearer Is this like the Power Resume Feature?
If so, I dont use it and I am not a fan of it for two reasons.
Firstly, if you are not nearby and everything cools down, the print will lift from the bed.
Secondly, the ones that I have tried re home before commencing again. They never go back to the exact same spot and is always off just a touch.
If the print shits itself, I just restart it.

yeah. but the online config tool has a bug and renders the config useless if you enable the power loss / resume function. but if you don't plan on using that then go forth and configure ~~without worries:)~~ with one less worry:)

Cherno Alpha

@bearer There will be plenty of worrying when configuring it. Never really done this type of thing before, but I have figured out most of the other things with printers. I am an expert on repairing my Raise3d machines

@bearer The Configurator code has been fixed on Github (and network has been put back at the beginning of config.g, so at least people should be able to connect to DWC), just waiting for the online configurator to be updated.

@bearer Actually, it's already been updated and M911 in config.g has double quotes around it, but you have to clear cache to make your browser use the latest version. From Christian:

Check for version 2.0.1
Can be seen on the start page. If it displays v2.0.0, clear your browser cache

And my mistake, the network code hasn't been moved back to the beginning yet.

The Duet has arrived, I am looking at a piezo bed levelling system for this, is it fiddly to set up and is it reliable? Alternatively what is the most user friendly bed levelling system? The bed is glass.

Therein lies the rub. They're all pretty picky in some way or another. Pick your poison.

@nhof Just looked at the expansion board and I need to get one, problem is the Australian reps dont have any at all so will have to get them from overseas. Yay for freight charges.

Cherno Alpha

Ok, so I have installed the duet ethernet, and the expansion board to go with it.

The problem that I am encountering at the moment is with the Z axis.

X and Y home and operate perfectly.

Z is the issue.

We have been able to get Z to home. Once home, if you press + 5mm it does not operate. If I go - 5mm it tries to drive the hotend through the printer.
The Z dive height has been set to 0.

To continue testing we have to manually wind the Z axis to try something new.

Any suggestions to try would be great.

Thanks,
Brad

try posting your config.g and homing files then we can all have a look and see if there is anything obvious.

@Cherno-Alpha said in 3DP1000 Duet Ethernet Conversion:

The Z dive height has been set to 0.

Why would you set it to 0?

Have you seen this? https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z

We'd need to see your config and homing files.

Cherno Alpha

@Dougal1957 , @Phaedrux
Will post the data below,

We set it to 0 after the first time we were setting the other axes it tried to drive it down. It is only at 0 till we have it sorted.

This Axis is functioning correctly, so I thought I would also post this as well just to provide further information.

Does Z axis travel correctly normally?

Note that the motors probably have a minimum pulse width of 3us, so you may have to guarantee this in order for the motors to run properly at higher step rates.

Something like:

M569 P5 S1 T3
M569 P6 S1 T3
M569 P6 S1 T3

Depending on what machine you have the motors will either be these: https://www.applied-motion.com/sites/default/files/hardware-manuals/STM23R Hardware Manual 920-0056D.pdf

or these: https://www.applied-motion.com/sites/default/files/hardware-manuals/TSM23P-Hardware Manual_920-0083B.pdf

Just look at the connectors.

@nhof
Thanks for the advice. I will have a look and test to see how that goes.

Cherno Alpha

A Bit of an update.

After getting my mate to spend way to much time on it troubleshooting the problematic Z axis issue, he decided to make the nema 23s just motors instead of integrated steppers. Not long after I had a fully functioning Z axis. The X and Y axes are still the integrated stepper and work well.

Printer is calibrated on the XYZ axes. Tested the extruder side as well all functioning. Only thing really left to do is put the bondtech on it and the usual bed calibrations etc. Then we are off and printing.

Thanks for all the assistance in getting this up and running.
