Do the drives clear faults when disabled and enabled again?
Most of what i used did, so i never needed to add anything except the fault inputs.
Fault input should disable the machine by disabling drives so all that it required to clear was to press F2/enable and move on.
 

I made short video showing how the drivers retain the current step count when they are wired up like it's described in the manual from Delta.

Nicely done, for sure.
Thank you.

Hello,
i'm probably trying to do the same configuration like you.
My intention is to somehow preserve correct position in linuxcnc based on encoder position.
Did you try this with running linuxcnc? Because video only shows, that driver keeps the position after alarm is cleared.
My question is what needs to be done in hal file to make it work.
Also would you mind sharing your config?

I'm just getting started with LinuxCNC so I haven't gotten the servos mounted on the machine yet. I'm currently making the control panel and ball screw mounts.

When testing on the bench LinuxCNC seems to keep the position just fine but in practice when there is some inertia involved you'd most likely need to hookup the encoder outputs from the drives back to LinuxCNC in order to be able to use this functionality to it's full potential. As without them LinuxCNC doesn't know if the servos have actually kept moving a bit after an e-stop was triggered.

 

These servo drives have a lot of features which I'm not using and it's probably gonna take a while before I even scratch the surface of their potential.

My HAL file is completely standard at the moment, the servos are configured as normal steppers as the loop is closed in the drives. I'll post the complete HAL setup as soon as everything is up and running. I'm afraid I'd post something completely incorrect if I uploaded my current configuration as it has not been run on the actual machine yet.

That looks all very organized and clean. What is the trick for keeping the electric cabinet organized?

Did you figure out all the components in advance and plan according to their size?

Do you have any prior experience with electrical cabinet planning?
Really impressive: An electrical panel that does not look "hobby".

Thank you, I think the trick is good planning, good attention to detail and a bit of OCD image missing /media/kunena/emoticons/laughing.png

I started by selecting the components based on the capabilities I was looking for focusing particularly on the FPGA/controller, servos and low noise. When I had figured out the recipe I ordered everything almost at the same time to make sure nothing went out of production before I could finish the build.

When the parts arrived I laid them out on a flat surface, measured everything and ordered the metal enclosure I thought would be the best fit

 

I have no prior experience with electrical cabinets. My profession for the last 20 years was building large enterprise/government IT-systems from scratch and my hobby has been building/racing my own car. But I guess both my work and hobby has required good planning and a lot of attention to detail from start to finish so it's probably something I've carried over from those experiences.
