First Start Up - E Stops

We're getting somewhere!

So i went to line 258 and changed the signal name like you suggested and now i am getting a new error. It doesn't seem to recognize the way i called the pin out. I wish i was more familiar with how to trouble shoot these, see error below:
....hal:334: Ini variable ' [HOSTMOT2](7i96s)' not found

i don't know what the HOSTMOT function does in this context but its not in anywhere else in the file other than being loaded at the top of the .hal file

Can this arrangement (servo drive internal homing) be used together with absolute multi-turn encoders on a dual motor gantry?
I'd like to use the multi-turn encoders to get away from home switches if possible...

Progress!
I always comment out the line causing the error(s) so Linuxcnc opens, then review things in halshow and your hal file to get the right pin name etc but by the looks of this, its telling you the line number and the fault so maybe change the signal name to something like aa-pos_fb then review

okay so i went to that linked tutorial I commented out the existing estop loop and ended up actually testing code from the last entry on the first page (copied and pasted below) but modified with my pin for the estop.
Code i am using:
loadrt estop_latch addf estop-latch.0 servo-thread net estop-loopout iocontrol.0.emc-enable-in <= estop-latch.0.ok-out net estop-loopin iocontrol.0.user-enable-out => estop-latch.0.ok-in net estop-reset iocontrol.0.user-request-enable => estop-latch.0.reset net remote-estop estop-latch.0.fault-in <= hm2_[HOSTMOT2](7i96s).0.gpio.040.in_not



Now i am getting a similar error where it it thinks pins are double assigned. Should I have commented out other pin assignments? Or could i not be assinging the pin corectly? 
error message:
.hal:258: Signal 'a-pos-fb' can not add OUT pin 'hm2_7i96s.0.encoder.00.position'. It already has OUT pin ' hm2_7i96s.0.stepgen.03.position-fb' 2034

nawaf are you using regularmac800?

Yeah, thanks, cakeslob, for the GUI mod.
I am using a 10-inch touchscreen with a resolution of 1024x600 and I want to use the Axis GUI with buttons that are large enough, and I saw your mod and tried it. It's great because the buttons are big enough.
But for the open file dialog, the buttons are not big enough for my fingers, making it a bit difficult to touch them on my screen

QtPlasmaC v2.9 - Time between turning off and back on the arc on a Powermax 105

Category: Plasma & Laser

Are you using Mode 1 and the ArcOK signal from the CNC port on the plasma cutter? If not do so. This will  let the plasma is tell you the Arc is OK, not some half assed guess based on the arc voltage.

Also on some plasmas, there is a setting that tells the plasma is turned on and off by seperate button presses. make sure its not set like this although if you using a machine torch, this should be overridden.

QtPlasmaC v2.9 - Time between turning off and back on the arc on a Powermax 105

Category: Plasma & Laser

Hi everyone. I hope you all are doing great.
I am trying  QtPlasmaC v2.9 for the first time. I have done some retrofitings of milling machines and routers with the Linux CNC, but never had worked with a plasma before.
I am finding out that the Plasma machines have some specific issues to deal with.

I am using a Hypertherm PowerMax 105 plasma source.
Everytime the plasma is turned off, the powermax start a process that Hypertherm calls overflux, blowing air trough the torch to cool it down.
During this overflux phase (aprox. 15seconds) the start torch does not work (on the powermax). It seems that the first pulse reduce the air blow and the second would start the torch.
I am having a problem because during a program executin, this first start to the powermax during the overflux does not start the torch, but the powermax send the signal of arc ok to the QtPlasma.
As Powermax sends the arc ok signal to QtPlasma, it does keep running the program, as it understand the arc is ok. But the arc is not ok and it is not cutting.
Does someone knows how to solve this situation?

Thank you very much

This reminds me I need to mount the XY limit switches. Some tech at the company that donated the mills physically removed them. Kind of understandable since you could not jog the machine off the limits as they outright interrupt the drive enable circuit.

It's also important to have the drive enables working so a following
error will disable the drives.

I have two relay outputs I need to get wired up. The default wiring does not give direct control of the drive enable relay which in turn energizes the main contactor. There is a reset relay that latches the enable relay and an error/e-stop relay that interrupts the enable relay.

I will pull the belts off all three servos. Need to figure out the ratio in any case.

Linuxcnc 2.9.2 and 2.93 images for Raspberry Pi 4b & 5

Category: Installing LinuxCNC

All my Pi's are 4GB.

Along with my Rpi5 I also have a RPi400, basically the same as a RPi4 with an slightly upped clock speed. I can say I've never come across this issue (even when rod was polishing his iamge utility).
I don't know if this will actually help, but you could try comparing the config.txt files on the Linuxcnc image & the Rasp OS image and see if there is anything that sticks out. This is just a guess.

It might pay to monitor the 3v3 line when booting, both versions, and see if there is anything untoward. Again just another guess.

But yeah it does seem like a confusing issue.

First of all your opening post was great. I'm actaully giving it a go now, just wish I had a nvme drive hooked up to the PCIe bus.
There's a couple of points regarding Linux kernels.

Sometimes the latest kernel may not be the optimum for your hardware.
The kernel you are using is a "release candidate" whilst usable for all intents is still going through some work.
The 6.1.y branch works fine on the RPi4, I think the kernel in the Linuxcnc image maybe 6.1.54
The RPi platforms with regards to Linuxcnc are a little different to the x86 platforms. Your Rpi4 & Rpi5 hardware is what it is. Whereas you may need a specific kernel dpending which x86 motherboard you buy.
The Rpi branch that appears to be active is the 6.6.y branch, so one could assume this is the branch that is receiving the most "bug fixies".
Simple things like isolating cores 2,3 will see latency drop. There doesn't seem to be as many options/tricks for latency on the RPi platforms as the x86 platforms.
I would chose to use a kernel that is a couple of version behind the the latest and greatest if it more tried in the real world and has better latency.
In my discussions with royka we talked about the fact that a kernel that is a little older is sometimes the better option.
Due to the issues with wayland I would recommend the use of the image form the Download page, Xorg is used. Plus it's easier to deploy ;)

Mind tho I'm not saying this is the only way to do it.
What I would suggest is trying some of the earlier kernels to see how performance differs.

One thing regarding the 6.6.y branch.
The latest version is 6.6.70 which I couldn't find any real time patches for.
The previous commit is 6.6.65 for which there are rt patches, but for some reason the overlay's aren't in the source. Which is a pain when building an image using Rod's image builder.

It seems, ATM, the deeper you dive it can seem a little confusing.

Sorry for the multiple posts but this editor is PITA.
