That ECP5/i5 board is VERY cool.

On your Git page you mention the network interfaces are not supported, do you mean we can't use a Wiznet module or are you referring to the 30pin ethernet connector on the dev board ?

Having over 100 IO pins available is definitely the dream, is programming as easy as the tang nano? Will it program via the USB-C connector within Riocore like the Tang?

Would there be any advantage in getting the i9 module over the i5 for our purposes ? It works out more expensive but not too much.

Cheers.

Is it still recommended to mount the THCAD on the outside of the plasma power unit when the power unit has a voltage divider? I was thinking it wouldn't make much difference since the start and ok to move are coming directly into the electronics box.

Hello dear forum, (Translation GER-ENG Google)

Short introduction:
I've been a fan of LinuxCNC for over 15 years, and unfortunately due to a lack of time (I'm sure many of us have) I've neglected my hobby a bit in recent years. I'm a bit out of programming in HAL and am looking for some food for thought or a solution to the following problem: 

Compensation between B and C axis required. 
I built a rotary/tilt table for my milling machine. Since my installation space is very limited, the whole thing had to be relatively small.
Harmonic drives were used for this purpose, the shaft runs through the HDrive of the B axis to rotate the HDrive of the C axis. The whole thing is solved via belt drives. Since the motor of the C axis does not pivot, it rotates when the B axis rotates. Now I need a compensation that compensates for the position of C every time the B axis moves. For one revolution of the B axis I need about 1/51th of compensation at C. My idea is to compensate for the whole thing using moveoff. 

Are there already solutions that might be better, or has anyone done something similar?
I would appreciate any help and tips.

Hallo liebes Forum,

Kurzvorstellung:
Ich bin sein über 15 Jahren Fan von LinuxCNC, und habe leider durch Zeitmangel (haben sicher viele von uns) mein Hobby die letzten Jahre etwas vernachlässigt. Ich bin etwas raus aus der Programmierung in HAL und suche einen Denkanstoß bzw. eine Lösung für folgendes Problem: 

Ausgleich zwischen B und C Achse benötigt. 
Ich habe für meine Fräse einen Dreh/Kipptisch gebaut. Da mein Bauraum sehr begrenzt ist musste das ganze auch relativ klein werden.
Dazu wurden Harmonic Drives verwendet, durch das HDrive der B Achse läuft die Welle um das HDrive der C Achse zu drehen. Das ganze ist über Riementriebe gelöst. Da der Motor der C Achse nicht mit schwenkt, rotiert dieser wenn sich die B Achse dreht. Nun Brauche ich einen Ausgleich der bei jeder Bewegung der B Achse die Position von C Ausgleicht. Bei einer Umdrehung der B Achse benötige ich an C ca.1/51tel an Ausgleich. Meine Überlegung ist das ganze über moveoff zu kompensieren. 

Gibt es dazu bereits Lösungen, die evtl. besser sind, oder hat jemand ähnliches gemacht?
Ich würde mich über jede Hilfe und Tipp freuen.
Kai

Having completed a new CNC build, I am fine tuning it. It is a dual X-axis machine (XXYZ), and I was looking at using matrixkins to square the X and Y axis. The document man9/matrixkins does not reference dual-axis. However I found a note (written in 2022): 
"Dual-axis gantry machine support might be worth adding, but I don't have such a machine myself."

Was there an update related to dual-axis use? Where can I find the source?

Thanks,
Robert
