No need, since 2.8 the joint/axis is implemented in LinuxCNC, so just choose "tandem joint/axis" in the wizard.

?? It is a usual setup, each X-ballscrew having its own stepper and home. For small corrections I could of course use HAL and change the HOME location a bit. The whole X bridge is very solid though (has 20 mm linear rail and two linear bearings on each side, and a profile of 160 x 95 mm aluminium), and pushing manually I cannot rack it more than about 2 mm. I have not measured yet if it is out of line more than that, so I'll do that first, might work. I found the matrixkins source, no mention of dual axis there. Looks modifiable though.

Hello,
i have a b - axis and i want to home the axis at the same time as the rotorhoming seqence is running (bldc component) 

I run a etel ddm with a 8i20 and a siko encoder with index

Any ideas?

Thanks

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.
Russell.
 

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.
