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

Can you give more information about this IGUS cantry and the motor(s) you are currently using to drive it?
-
The original igus steppers were rated at five point something amps. apparently. Its the 600 x 600 room with the very deep top beam:
I got a lot of conflicting info early on, so swapped them out for some decent regular nema 23.
Am pretty sure it is just too chunky and have given up on it. I'll try it on a duet and if not swap it for a buzz automation set up. It's wasted too much of my time time at this point tbh.
Substantially quicker and cheaper to change the gantry than keep chasing my tail. especially now with losing the painful marlin settings.

I can't post the url to the gantry as it is flagging as spam. Is there a way round it please?
-
It's an IGUS drylin room gantry 600x600 with some very expensive steppers (330 each remarkably). It can work beautifully but has never liked complex prints.
-
weird, posting URLs should work, probably the anti spam being super cautious because you are a new user. try with spaces in the url

yes! sorry, should have said.

annoyingly igus does not provide any information about the stepper motors with encoders used on that gantry. you say you replaced them anyway? what with (model number?)

have a look at the specs of thse motors when plugged into the EMF calculator:
You will need to put the correct information for your machine in there
For more info see:
https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Considerations_when_choosing_stepper_motorsany you can try different values in the tool to see how motor properties effect your maximum speed achievable.

I only run at 60 mm/s max as my hot end maxes out then. appreciate acceleration etc is a factor too.
600x600 is not a particularly big machine imo. fairly sure the gantry is just too meaty for this application.

At over £2k a pop I'd tend to agree. For info, my machine frame is 600 x 600. Although the build plate is 400 x 400 the gantries are 600 x 600 and I just use two 2020 extrusions for X and 4020 for Y. Others have built much bigger machines powered by Duet.

These iirc:

Duet Wifi and Duet Ethernet can drive those motors easily. Use 24V power. The maximum speed will be limited to around 150mm/sec (see Tony's post), but from what you have said, that's acceptable to you.
Duet Maestro is a little under-powered for those motors. Duet 3 would be overkill unless you need the 6th stepper driver or the expandability.
-
Thanks all. I will look at getting @Fusedeep running of a DUET ethernet (my friends advise against wifi and in my experience I agree). I run at 24v these days as it happens.
Based on the above and the specs it looks like I would not need any additional pop out/daughter boards for @Fusedeep?
I notice there seems to be a need for a thermistor additional board? Obviously I want to make sure I am getting all the parts I need.
Will make the polar machine as i reconfigure @Fusedeep.
BTW, int the online config tool I cannot see a polar option, delta yes, polar no. Did I miss something?
As mentioned the Maestro's will sort my Makergear M2s nicely by the look of it.

ps, the IGUS gantry comes int at 4K with all their specialist proprietary cables, end stops and the like. All gifted by IGUS!

No. You only need daughter boards if you want to use thermocouples or PT100 sensors. The more normal NTC thermistors are supported without any additional hardware.

The online configuration tool is a sort of "get you started" thing. Not every kinematic option is provided for in that tool but you could select some other kinematics to get most of the configuration done for you, then just amend the resultant files to suit. But there are people using Duet with Polar kinematics so I think it is supported.

I am a little confused about the various thermistor options, or not?

What would I need to do a straight swap to a 24v E3D volcano please?

As per my post above - If you choose to use an E3D thermistor with the Volcano, then you don't need any additional hardware. But if you choose to use and E3D PT100 or E3D type k thermocouple with your Volcano, then you'll need a daughter board.

@deckingman Thanks, I posted my last post without seeing your reply.
I'll get moving on this I think, intend to get the screen too, I assume this will enable me to add an STL/OBJ via SD card and run a print independent of a pc?
-
@FuseDeep You can run a print independent of a pc with and without a screen.
The SD card in the duet itself is used to store the gcode.
The screen enables you to operate the printer without needing to use a phone or pc. Of course, a PC is still required to slice the gcode.I have a screen for my printer but rarely use it as I either use a nearby pc or phone to start a print.
