I see.

What are pins 8 and 9 used for?

(Just wondering)

I did a hydrauic press brake without conventional axes of G-code some time ago. I am not sure that was worth the trouble in the end, as with axes you get homing and speed control for free.

There might be some reusable ideas there though.

You don't need any PWMgens,

The PID output would be connected to the hm2_7i95.0.7i83.0.0.analogout-NN
pin in hal

Hallo,
ich benötige mal etwas Input...
Ich versuche einen Servocontroler mit +/-10V anzusteuern über die 7i95T+7i83.
Ich habe mir jetzt 4 PWMgen per Bitfile erstellt, verstehe jetzt aber noch nicht, wie ich die Verbindung

pid.x
hm2_7i95.0.pwmgen.00
hm2_7i95.0.7i83.0.0.analogout

hinbekommen soll? 
Kann mich wer in die richtige Richtung weisen?

 

The other L-modes also don't work. Timeout doesn't work. Nothing happens after 10 seconds. Yes I'm looking at the digital-in-xx pins. LinuxCNC version on the splash screen is 2.9.0~pre1+git20230208.f1270d6ed7

L3 is correct for this application, but out of interest, does L1 work?

Does the 10 second timeout work?

Which LinuxCNC version?

In halshow are you looking at the motion.digital-in pins? (rather than the IO pins)

Maybe.

That's shown embedded in Touchy, but it could be standalone.

I also did a similar thing with a hydraulic press-brake, but don't know how that worked out in the end. That didn't use LinuxCNC at all, it was pure HAL. But I am not sure that was the best of ideas in the end.

I think that's about as good as it gets, and it's perfectly usable for most purposes (especially if you don't plan on using software step generation or encoder counting)

Gmoccapy is written in Python, you might want to look at just adding some more code. If you know Python, that is.

Just open the terminal and type

halcmd setp stepgen.4.velocity-cmd 40

Anything that is a valid HAL command for the HAL file can be run from the command line with "halcmd"

If you want to do more than a single line, then

halcmd -kf

will open an interactive HAL session where you can type commands (without halcmd) with tab-comoletion and command history.

To exit the interactive session, type "exit"

But if you want to control it from a switch, or pot, or VCP then that can be done too.

Hello, I reset the device to factory defaults as you advised, but the "Amplifier Fault" error still persists. Is it because the DC setting is not set correctly? I'm wondering if you have any other advice.

Hello, I am trying to build a cnc band saw. I am looking to build a custom python gui. Does anyone have a example of a super minimalistic hal configuration? All i would like is to power outputs on and off some inputs and a linear incremental Encoder to track position i see there's lots of configurations for plasma mills lathes etc but not much that is this simplistic. 

Resolvers are very good (and very expensive) they will never break. (the bulbs in old optical encoders would burn out eventually, LEDs tend to last longer, but can still fail)

Given that only one drive has failed, have you looked at repairing it? It's unlikely that a hybrid system of one servo under LinuxCNC control and one under original control control would work very well.

Have you asked Mesa if the 8i20 is likely to come back into stock?
Do you know the power and voltage spec of the motors?

(I am on a train on mobile data, not in a good position to look through documentation links)

I think it exists in canon, but last time I looked at this canon wasn't availalable in standalone python code. (or I failed to work out how to use it)

However it is available in remap code. So if you remap the S word (spindle start) you could check the extents at that point, add on the tool length, and decide if the spoilboard will be spoiled....

Actually I'd like to know why bash isn't /usr/bin/bash . As far as I'm aware all the build scripts for the image reference/usr/bin/bash and there was no issue when in the qemu environment.

Once again posting your code would help rather than fumbling around in the dark.
