@dc42 Thanks. I think I may just use the existing duet rotating magnet filament monitor that I used with the previous extruder. This is located off the print head before the ptfe tube that feeds the extruder, it's simple to run the wire along with the power/can cable to the roto toolboard and I wouldn't have to worry about routing/securing the ffc cable near the filament feed. I don't think the integrated duet roto filament monitor offers any advantage over the original rotating magnet filament monitor, I don't have a use for the feature button.

I have a revo roto extruder with a roto toolboard but mounted slightly differently to how the documentation shows. I see that it says the maximum length of FFC cable from the duet3d roto filament monitor to the toolboard should be no longer than the supplied 30mm length. Is this a hard limit? I'm probably going to need something like 40-50mm or so, is this likely to be an issue?

Thanks.

Yes, it's not the lightest, I did need to make up an extra adapter bracket to use the horizon strain gause z probe which added a little weight to the print head assembly. I see there are a few that have done corexy conversions on these printers. Besides slightly faster print speeds are there any other advantages to running corexy?

I did use one of the high flow 0.4 revo nozzles which seems to easily manage 20mm3/s+ with pla, extrusion speed isn't going to be the limiting factor on this.

Picked up an old Folgertech FT5 a while ago. Finally got round to finishing the upgrade. Has many of the 713maker cnc upgraded mounts and brackets. Swapped out the old controller which was running Marlin with a Duet 6HC, Roto Toolboard, Microswiss NG extruder with a revo nozzle and a Dyze Design Horizon Z probe.

It's not a fast printer but print quality seems good, probably needs a little tuning to get the best out of it.

Many things, upgrade parts and mounts for bikes, timetrial starting clock, pool shot timer, electronic telescope focuser conversion, workshop storage bins/trays/holders, battery adapters, camera flash reflectors, speaker mounts and things I've long since forgotten about.

Just a brief follow up to this, I never could get a good first layer with this setup. I tried with a bltouch, inductive and IR sensors all gave similar results, the first layer was very inconsistent.
I have now installed a dyze designs horizon z probe which uses the nozzle for z probing, mesh bed compensation now works as expected and I get very good, consistent first layers.

@droftarts Thanks Ian, it's now working!

I didn't look at M906 as it seems to work with the extruder connected directly to the 6HC even with it early in the config. Something to remember for future installs.

@jay_s_uk Thanks, that did complete the downgrade on all boards and the pi.

Duet 3 MB6HC 	MB6HC 	3.5.4
Duet 3 Expansion TOOL1RR
TOOL1RR 	3.5.4
Duet Software Framework 	DSF 	3.5.4
Duet Web Control 	DWC 	3.5.4 

This has not changed the behaviour, still no movement on the extruder motor.
I have just double checked the cable from the toolboard to the motor and connectivity is fine on all pins.

@jay_s_uk The second M997 S2 command did flash up a notice saying it was upgrading, but nothing seems to have changed, restarting the board shows the 3.6.0-beta.2 firmware on all boards and the sbc packages are still on 3.6.0-beta.2.
If I ssh in to the pi, I see that the duet3d.list is now showing "deb https://pkg.duet3d.com/ stable-3.5 armv7" so it is on the stable channel but nothing downgrades.

@jay_s_uk Does that downgrade the boards and all sbc (pi5) packages too?

@Phaedrux I haven't run this configuration with 3.5.4. With the previous setup, upgrading to 3.5.4 broke the setup and the board firmware became corrupt and had to recover with a usb cable. So I upgraded to the latest beta on the board and sbc and all has been working well.

I presume it's not a simple task to downgrade both boards and all the sbc packages to a previous version?

@Phaedrux Entering that command to the console at the web interface produces no output.

@jay_s_uk Just powered everything back on, set the hotend temperature and set to extrude 20mm from the paneldue interface. Nothing appears to happen.

@jay_s_uk yes, tool selected and hotend up to temperature.

I made up a new cable and wired the extruder motor directly to the 6HC, changed the address from '20.0' to the 6hc output and it works.

@jay_s_uk said in Roto Toolboard, no extruder motor motion?:

M115 B20

Yes, the address is correct, the z probe and nozzle heater work.

Duet TOOL1RR firmware version 3.6.0-beta.2 (2024-11-12 08:12:15)

I'm unable to get the extruder motor to work when connected to the roto toolboard. I have connected it to an output on the 6HC and it works correctly.
The printer uses a 6HC (sbc mode) with a roto toolboard, micro swiss ng extruder with a revo heater/nozzle hotend and dyze design horizon for nozzle probing z height.
The extruder is connected to 'driver 0' on the toolboard, I have double checked the wiring A+ and B+ to the upper pins and A- and B- to the opposite lower pins. Checked the coil resistances to make sure I have the correct pairs wired.
Just updated the the latest firmware just in case.

I'm possibly missing something obvious, suggestions as to what I can test next?

@dc42 Thanks, that seems to have fixed the issue, it now reads within 1 degree of what my infra red thermometer reads.

@elmoret Thanks, yes provided that accuracy is better in the operating termperature range. I just had not seen such a lower temperature accuracy issue on the 3 other printers I built using duet boards, this is the first tool board I've used so perhaps it's related.

@jay_s_uk I did check on the datasheet for the 104NT-4-R025H42G and this shows that the expected resistance at 10degC is 208.8Kohms which is about correct with what I measured. I purchased this from E3D.

Thanks for that, the value does not significantly change the temperature displayed, maybe a degree or so. If I change the B value to something like 8000+ or so the ambient temperature displayed is closer to reality, but I would think that would mess with the scaling at higher temperatures.
