8 Feb 2025, 20:51@DIY-O-Sphere the releases are now released as part of the main RepRapFirmware repository. E.g.:
With the hint of @sebkritikel I got that.....would be nice to add that to the documentation....
@T3P3Tony said in Question about Sammy-C21 board:
You are correct that the default firmware has lots of IO enabled so if that's enough for @fcwilt then they won't need to modify it
Hallelujah....

Sorry I have overseen that the section is for the source code.
But still can't get it to see the right release.
Shouldn't it show 3.5.4 and switch when you select a different version in the branch pulldown?
Or is it just because the zip file for the version is missing?
I would suggest putting the section Loading firmware at the end. And i think it needs a bit of a rework
I am still confused as to why the firmware has to be adapted. The table shows many ports that can be used as input.
The original request was here
As far as i can see, standard io's can do the job.
What am I missing here?
@sebkritikel
Thanks for the clarification. And for the correct reference.
If you go to the sammy-c21 documentation. The dev branch is linked and as far as I can see it ends with 3.4.2.
Maybe i'm too stupid to use github.
@fcwilt
It means that the effort is quite high.
It's a poor performance that the latest firmware is no longer provided.
Until now I thought the Sammy-C21 is a cool option, but not any more....
@fcwilt
To me it sounds like you have to buy a cow to get a liter of milk.
@53581
Bang-bang control on the bed could cause kind of stripes.
As far as i can see, your config. may have been created for an older firmware. The heater parameters have changed with 3.4.
I don't know if that really makes a difference.
But I would change to PWM-control and autotune the bed heater and the tool.
Please also post the content of config-override.g as the parameters should be stored there.....
@T3P3Tony
Can you please provide an update on this?
@DaveA
Maybe set the custom end G-code as described here
https://forum.duet3d.com/post/314534
@droftarts
For push-pull M567 also is missing....
@Tinchus
I would suggest the following additions or changes:
In config.g
; ENDSTOPS
M574 X1 S1 P"!io8.in"
M574 Y1 S1 P"!io6.in"
M574 Z1 S2 ; configure Z-probe endstop for low end on Z
; bltouch
M950 S0 C"io7.out" ;change S2 to S0
M558 P9 C"io7.in" H5 F100 T3000 R0.2
G31 X-7 Y37 Z3.73 P25 ; bltouch offsets
M557 X7:193 Y18:195 S26.5:29.5 ; define mesh grid
In deployprobe.g
M280 P0 S10 ;change P2 to P0
In retractprobe.g
M280 P0 S90 ;change P2 to P0
@TomasL
Depending on what is needed, the positive voltages can be used together.
But then also pay attention to the cable cross-section
@Tinchus
Sounds plausible to me, BL-Touch does not like magnetic fields.
@Tinchus said in Bltouch not deploy sometines it does:
I had exactly the same issue, that was driving me crazy....
check the pin
"Try loosening or tightening the set screw slightly to adjust the trigger sensitivity."
The description how to set up the srew is in the manual
In the end a quarter turn had reliably solved the problem.
I have noticed that the limits of the old and new files are different. In addition, the old homing script uses hard-coded limits and the new variables dependent on config.g.
So first check the correct values and adjust them for M208 in config.g
@droftarts said in How hard is setting up CAN connected boards?:
Click on the "Connecting WITHOUT Duet 3 Tool Distribution Board" tab.
Oh yes, the tabs....I sometimes overlook them. I'm probably not the only one....
@droftarts said in How hard is setting up CAN connected boards?:
The problem I have for documentation is that there is hundreds of variations of ways to connect multiple boards together
In my opinion, no diagram is needed for such complex wiring. Such machines are only built by experts.
The documentation with the new diagrams is the right way to go.
The section "Expansion board connections" definitely needs illustrations / images.
It's a pity that the illustrations of wiring the 1LC are no longer available. Dozuki
Among those who voted with easy are some who started with the old documentation .....;-)
@carlinicompetizione said in Problems from the second layer to the 7th layer:
I need to add some command to the config. g to load and activate the created map?
There are several ways to do this.
I have added it to my homing routine.
But it also works at the end of the config.g. However, you must definitely call G29 before printing.
There are also several options for G29. I only load the saved map.
If the printer is stable, the mesh does not need to be recreated each time.
