What would be the best 3d printer board to use with remora spi and raspberry pi 5 please? For k40 style co2 laser, so I dont need too many motors.

Of topic , bare with me , posting quote , that _ _ _ _ _? _ _ _  in editor ,i'll get it somehow ,
did struggle too posting two links in one post .
And the  manual editing in source code mode?  some i dont get yet ..
should find it on Kanena forum help ,  
As long as it does login post & reply !!!
Cheers

Ich habe ein Problem mit meiner Karte, sobald ich 5v anlege blinken kurz die Leds auf und das wars.
vor einem halben Jahr bin ich umgezogen und bis dahin lief alles ohne Probleme. Heute habe ich endlich mal Zeit gefunden mich um die Fräse zu kümmern und wollte sie einschalten, ohne erfolg...
Mit einem zweiten Netzteil habe ich genau dasselbe Bild. Die umliegenden Wiederstände haben alle ein wert, leider weiß ich nicht was sie haben müssen um zu sagen ob einer durchgebrannt ist.

This should be close:

Thanks , did not expect that so quickly !!
may you already started to work on it the 2 years ago ,anyhow ,
more bow on support , 
Does seem very close if not exactly it .
Let's see what olds sl bulky bobs get to with this  .

Picture a whole bunch of penguins clapping or at least one .

In a terminal
sudo lspci -v
See if there is a parallel port and at what address.

[edit]
Ah ok, you are changing from the probe to T42 when the routine fails.

Hi Martin,
Nice Project! Was your Retrofit successful?
I also have the same Knuth Mark Super Cnc. And the Gplus 450 make problems.
Can you give a short summary of your Retrofit, what you change and how? Maybe pictures too? That would be very helpful .
Thank you and have a nice day!

Maybe it's useful info ...
i had to power the RPI5 using a normal 5V/10A DIN power supply. Manage to do it and keep 4.7V at 3.1 A , enough for RPI to avoid detection of an undervoltage condition.
But then I was curios about the official RPI power supply ... and I have tested it with an electronic load: I've got the same voltage ( around 5.14V) from 0.5A up to 5.9 A .. at 6A it shuts itself down nice and safely ).
I think the official power supply is dinamically compensating the cable impedance by increasing the output voltage from the regulator based on measured current .
So if you need 5A , be very careful with the cable or just use the official power  supply , if possible ...
All of these where done with PD disabled ( a small USB-C breakout board with 5.11kohm on CC lines)

You can select from submenus, but the format isn't well documented and it might take some experimentation to figure out which menu and submenu are which number.

Heh! I never knew!
