@jay_s_uk I'm using the 6HC

I have recently updated to 3.5.4 from 3.4.6 and the DWC keeps loosing its connection while running the pre print macros and an error message pops up in the control screen when this happens. The message reads,

Connection interrupted, attempting to reconnect...
Operation failed (Reason: Service Unavailable)

I think this happens when it reads the following line in the macro,

M98 P"/macros/autoz/scripts/autoz_probe.g" K1 H5 A4 S0.004

Are the variables allowed at the end of the M98 line? The pre print macros continue and the print job finishes without any other issues.

@oliof Thanks for your help but I'm going to stick with 3.4.6 for now and try to simplify and rewrite my macros at a latter time.

@droftarts
These macros run when individually run.

@droftarts;
This is my startup script.

This is the G-Code I am trying to print, it heats the bed and then aborts.

I moved back to 3.4.6 and everything works fine. I went through the change log for 3.5.0 and I don't see anything that would cause it not to work on my printer. Any ideas what might have changed between the two versions to cause the print to abort after heating the bed. For some reason I am unable to upload my code or file to this site.

@oliof Which file should I include?

probe-screw-5sc.gcode I just updated to 3.5.0-rc2 from 3.4.6, I have a 6HC with 1LC v1.3 everything was running fine on 3.4.6 but now the print aborts just after the bed reaches temp. I am using Simplify3D. The error message is

Cancelled printing file 0:/gcodes/probe-screw-5sc.gcode, print time was 0h 1m
'abort' command executed

@droftarts I don't see IO_1.out on the toolboard but there is IO_0.out. It may be safer to just run them back to the 6HC unless there is someone that has successfully connected them to the toolboard.

Anyone know how to connect stealth burner led's to 1LC Toolboard? Can they be connected to IO 0 using +5v, GND and io0.out for data? Or do they have to be connected to 6HC.

@Wobi Hello, may I ask you what mount you are using for the 1LC tool board? If you have a link that would be great. Thanks

I keep getting a print pause during printing and when I run M122 B121 after print I get this for the Filament sensor. What does this report mean?

@dc42 Thank you

@Phaedrux Sense I am color blind I can't tell what color the LED is and the issue happens so fast the flashing LED does not change as far as I can tell. I am using twisted wire with factory crimps on both ends which is soldered to the twisted wire. I have run a new wire and ordered a new ver1.3 board so one way or the other the problem will be fixed.

@Phaedrux Price is not the question. Will a 6 foot length of untwisted wire work for the Toolboard?

I check the wiring and it seems to be OK. Attached are some other responses that I get from M122 B121 when entered when the Hotend temp hits 2000 deg. Is there some M code that can be entered to give more information on what is going on?

@thaug29

What is the max length for untwisted wire for the Duet Toolboard?

Duet says "Unshielded twisted pair cable is normally used; however over the short cable lengths typical of desktop 3D printers and CNC machines, the cable type is not critical."

What is short lengths? Is 6 feet to long for untwisted, unshielded?

@Phaedrux This is very odd, it will run for hours without any problem and then the print will pause and the hotend temp will jump up and down from set point to 2000 deg. It's on a Voron 2.4 and the wire runs thru a lot of cable chain. It mat be easier to replace the entire wire, I just don't know if it's wire or the board. I can try to check continuity and crimps.

Is there a way to determine if the duet toolboard is bad or is the wiring bad. I get the hotend temperature jumping to 2000 deg for a split second and when this happens I run M122 B121 and this is what is returned.
