If you want a real stable temperature u need to have more isolation.

Make a hot airflow like a oven inside the inner chamber (heated one). Make that chamber isolated with some high temp material or use basic rockwool.

Next let cool air flow on the outer chamber to leave the outside of your printer cool so you can touch it.

We build a machine with 1m x 1m buildvolume and 200 degree chamber this way. Little bit more complex but for 90 degrees it's almost the same. If you need more help please contact me.

I think i can say i have some experience with Duet3D boards and Dave's software.
For reference we produce printers from 3.5m tall and built more than enough of the smaller ones (60cm buildheight). All are using Dave's software. Never found a better supportive programmer than David!

Ofcourse there are bugs. Tell him and he will try to fix it. Don't expect it next day, but believe me he will try his best!

I see Jason is banned allready and that's good! If you don't know how much time is given by people for free! and are bashing them for it? Please leave...

Guys we all have alot of respect for you! Keep up the great work!

All our printers are using Duet boards. (Tractus3D)

Buildvolumes are from 20x30cm up to 100x210cm

Look at your homedelta.g file

There are some lines that will put the head down a bit after homing. Still using H1 there will make it fail. Use the H2 to move the motors down a bit.

@dc42

Here are 3 versions (5.0.0 and 5.0.1 and 5.1.0)

S3D500-Cube250micron_30m_15gr_PLA_T3500SE_08n.gcode
S3D510-Caps_2h40m_PLA_T3000SE_1n.gcode
S3D501-Cube300micron_40m_8gr_PLA_T3500SE_04n.gcode

@dc42 Just to let you know we updated one of our machines to 3.5.0-b3 still with Simplify3D 5.0.0 and 5.1.0 no filament usage in the Jobs lists.

@dc42 said in DotStar not working from 3.4.1:

rameters. I think your LEDs were only lighting up in older versions of RRF because of the bug that we fixed in 3.4.

That worked out! A little more code to just dim the strip but we can dim it better than with the P value (that stops at 10 and R U and B goes down to 1)

@dc42 There is a white only dotStar which we use in our machines. We have large machines and can't use others as they are limited to number of leds. And we need at least white (color would be extra).

So there is APA102 (DotStar White) available which we use.

We only use P value to set the brightness level (works up to 3.4 beta 5)

When running 3.3 on MB6HC the DotStar leds (we use only white DotStar) are working perect with M150 X0 S10 P255
Updated to 3.4.1 they stopped working with any command, back to 3.3 makes it working again.

After some step by step updates we found out our system stops working from 3.4.beta6

Only changelog for DotStar is this in the beta6:
[Duet 3 MB6HC] With DotStar LED strip. If the brightness M150 P parameter (brightness) was not a multiple of 8 then the blue LED level was incorrect

@mfs12 We have just uploaded 3.1.1. and 1.24 and this still seems to work without any errors. to reproduce we just turn the machine on, please see our config below:

@dc42 Nope, those messages, from the picture in my previous post, keep coming up every minute or so

@jay_s_uk

Upgraded to the stable release, but still the same problem

@mfs12

We installed the firmware, but unfortunately it didn't solve our problems. Now we get a lot of error messages as shown in attached picture! We are currently running RRF 3.3 RC2 and WebControl 3.3.0 RC2 IMG_20210721_140124.jpg

@mfs12

Thank you very much, we are going to test it.
It happens from 3.2.x up and before we used (3.1.1 which was clean/no problems)

We even have it now on our small machines (desktop)

We are going to install the firmware now and will report within 2 hours with a result.

@Phaedrux resistance is in range and even much lower. We took a original cable (longest which was supplied before and meassured 3x as much restance. So this is not the issue as we think. Thanks for thinking with us.
