@bearer I know with Linux if you don't have the correct case it sometimes it'll say the command is invalid. So to eliminate any issues i made it all lowercase LOL

for commands and filenames yes, dns and hostnames doesn't matter. in general you'll have less issues avoiding mixed case and special characters (incl spaces) on linux indeed

I'm happy with my wifi right now. No issue there I found so far. LOL!

Thanks for asking this thread. I don't know much about this speed factor. But I am interested and I would like to get some more details.

It's not a bad idea to put one of those commands at the start of your homeall to clear any error states before trying to home.

@dc42 it also happens to the tprex.g files, but it moves downwards after the last G1 Z-2 command instead of upwards. Is it because of the Z offset that being applied and cancelled after a tool change?

@bearer Thanks! Switched the word order to hopefully make it more clear that it's not an alternative that is a PanelDue but rather an alternative to the PanelDue. 😄

@davidvh86 said in Creating thermostatic fan without heater:

yes i am. so would i replace h# with s3

The parameter in M106 is still H but its value in RRF3 is a sensor number, not a heater number.

I swapped over to a spare pair of linear rails I had laying around because this issue. it seems to have cured the issue, but i did also up size the bed and other axis's to 300x300x300 I changed the standard bed support which in my opinion was shockingly flimsy to say the least.

Ok here is the update. The test was a success! If you do not mind losing a mirror 😊. After I got back up and running, I also changed filament, I changed to 3Dxtech CarbonX™ NYLON PA6+CF. This filament prints very well by the way.

So, to recap, I used standard 12" X 12" mirror tiles from Home Depot. I particle blasted the mirror to get it some texture then added two layers of Nano Polymer Adhesive letting it dry between layers. I did not use a brim this time with the added texture from blasting the glass it was not nessary. Enclosure temp was around 82⁰C Extruder 275⁰C Bed was 110⁰C. I started to print last Thursday and printed thru the night until Friday then shut everything down around 10:30am with about four hours left to go in the print. I came back in on Monday morning and restarted the print it finished without to may problems.

First issue there is a small visible line where the print restarted but I could clean this up if I wanted. This restart line did not affect the strength of the part at all. I dare you to try to break this part! Next, The part was stuck to the mirror so well that it broke trying to remove the print. It also left small pieces of glass stuck to the bottom of the print. I removed these with a small die grinder and proper PPE of course.

You can see the re start line at around 62mm in the photo.

This is the finished part.

I think I will keep trying but will cut back on the adhesive. Thanks for all your help and have a great day.

@dc42 problem solved, thanks a lot!

@dc42
nice find!

i have this
https://m.aliexpress.com/item/4000118902487.html?trace=wwwdetail2mobilesitedetail&spm=a2g0s.12269583.0.0.305a4310FPZwDw

if i can only find a way to give it signal via the mic terminals, i mean rip it apart and feed it a signal to the pre or post microphone circuit.

can duet have an output that could be used as this?

my idea is to( convert a PWM output to an analog voltage level, producing a true DAC. All that is needed is a simple low-pass filter made from a resistor and a ceramic capacitor. The simple RC low-pass filter shown converts the PWM signal to a voltage proportional to the duty cycle.) from here:

but to make the duet output diffrtnt signals and asign an output pin.

it should work, I hope ,hahaha

hello, i need some help to with the rgb leds, can u explain me where did u connect the rgb leds on the expansion pins and what did u put on config.g file to activate them ? tnx i appreciate a lot

@dc42 said in Expantion port logic output:

M950 P0 C"spi.cs5"

Thank you, I got it to work now:)
P5 was the next free so my config file now have these lines to start logic 0
M950 P5 C"spi.cs5"
M42 P5 S0

My layer change script in Simplyfy3d as below.

G4 S0
G4 P500
M42 P5 S1
G4 P200
M42 P5 S0

I suggest starting a new thread. Link to this one of you feel is relevant.

what do you mean by "many printers not accepting arc g-code", all of the mainstream ones do, marlin supports it, rrf supports it, smoothieware supports it ?! iirc (have not tried myself) also the redeem (replicate stuff) and klipper support it too ... so where dis "many printers" that does not support arc g-code come from?

I made it work on the extruder, I could measure that there was a loose connection on that end and the other is probably completely finished. Thank you very much for the resistance table and your help. Without that I think it would have taken me a very long time before I had found the problem.

@biff-hansen said in Duet 3 6HC - Homing Dual Z:

Since we're not separating Z & U, Any ideas on how I deal with small differences in the triggering of Z & U to correct slight mounting errors?

The following might work (not tested):

Home both motors Use M584 to map Z to just one motor Command a short Z move to square up the motors Use M584 to map Z back to both motors If M584 results in the Z axis being flagged as not homed, use G92 Zxxx to tell RRF where the Z axis is

@DocTrucker haven’t progressed it, as my eldest (4) is about to start school, so it’s rather a busy time. I was inspired by this video: https://youtu.be/Ycfv3QIqvco where he ripped the motor, controller and battery out of an RC car. There’s a few other videos of similar swaps, just haven’t had time to go through them all! Thanks for the info, I’ll see if I can get further with it over once I get more time!

@dc42 Ah, yes! I looked at those when you tweeted about them a while back but they weren't available with the Duet bootloader at the time. Now they do, I've just ordered on to have a play with 👍
