You may have to invert the estop signal, as when you press the estop you are providing a 0v signal. You may also need to check whether the inputs to the estop are tied hi or low when the Estop is pressed.

Thanks for your reply, Lcvette!
Okay, I think I have a (relative )rigid machine for a hobby CNC. All critical plates are made of 20mm 5083 aluminum, heavy profiles filled with cement, an 80x160mm filled portal profile, 20mm HGR guides. A good standard for  a 1000x500 machine.  I aligned everything using angles and a dial gauge. I placed a dial gauge on the end of the Y ball screw, which shows only 1/100 mm of backlash. Using a spring balance, I pulled with 20 kg on the spindle in the X and Y directions, with a maximum deflection of 0.06 mm, in the X less in the Y direction. I think the mechanics are OK, as this deviation of almost 0.5 mm cannot be explained.
Ok, You say, my settings are correct. What is the reason for motor alarms at the reduction of FERROR from 1.0 to 0.1 and MIN.FERROR from 0.1 to 0.01? 

Stop posting new topics with the same question and tittle.

My SetupRaspberry Pi 5 8GBByte2Bot Parallel Port Raspberry Pi HatByte2Bot 5 Axis CNC Interface Adapter Parallel Breakout Board For Stepper Motor DriversPicture 1My wiring is as follows:Picture2

The motors move, the home switches register as functioning, the probe is not hooked up and the eStop appears to do nothing.From LinuxCNC V2.9.7 Documentation PDF Page 1854.9.3.7 External ESTOP button The standard_pinout.hal file assumes no external ESTOP button. For more information on an external E-Stop see the estop_latch man page.Yet from 2 pages earlier in LinuxCNC V2.9.7 Documentation PDF Page 183 I see this line in the HAL file:# create a signal for the estop loopbacknet estop-loop iocontrol.0.user-enable-out iocontrol.0.emc-enable-in I assume “man page” is a typo and this is unnecessary if I am trying to connect it to  GPIO25. A search of the document looking for “estop_latch” only reveals this on page 254Picture 3So my estop is on pin10, but that is GPIO25 on the Pi 5. I must refer to it as such.In my .Hal file I have the following lines:loadrt hal_gpio inputs=GPIO7,GPIO8,GPIO25,GPIO12,GPIO13 outputs=GPIO5,GPIO6,GPIO11,GPIO9,GPIO10,GPIO23,GPIO16,GPIO17,GPIO19,GPIO20,GPIO21,GPIO22,GPIO24,GPIO26net estop-out   <= hal_gpio.GPIO25-in  ornet estop-ext <= hal_gpio.GPIO25-in Using tools I can identify that all my limit switches are being read, but I have nothing to suggest the estop is being read.I have added“Addf gpio-input servo-thread” as recommended by ChatGPT, and that is not read by the programThe advice I am looking for is:
I would like to know how to connect GPIO25 to LinuxCNC’s E-Stop chain.I have tried:

net estop-out hal_GPIO.GPIO25.out => iocontrol.0.emc-enable-inand any variation thereof I could think of, failed.Eventually, I lost control of my servos and only when I removed all lines I gained control of F1, which controls the estop and F2, which powers the servos. 

I'm hooking a 7i84u to a 7i96s and I'm unsure about the power for the 7i84u
From what I understand reading the manual (page 2) there is an onboard switching power supply that will take FIELDB voltage down to logic level if W1 jumper is in the left hand position. So I can supply 24v to FIELDB and it's not going to hurt anything.
Or is that only if I was using 5V FIELD and anything above that I should be using a separate supply for VIN?

Also, from what I understand 
Both field A and field B need to be powered regardless. I've hooked my 24v power (same that is being used on the 7i96s field) to one of the grounds (pin 8) and into pin 1 (VFIELDB) and then a jumper from pin 2 (VFIELDB) into pin 3 (VFIELDA) so they are both powered with 24v.

Right now I've got a 5v line coming over from the same supply that I use for the 7i96s into pin 5 (VIN) and the W1 jumper in the right hand position. That seems to work, I have a flashing green light (CR6 activity) and I can see changes on hm2_7i96s.0.7i84.0.0.imput-00 in HALshow if I power pin0 TB3 (either with 5c or 24v)

Before I let out the magic smoke....
Thanks

Thanks for all info so far.
I decided to change the Y-axis also with a M4-(screw) spindle drive (not M3 as I said before), as I did on the X-axis.
Had the (almost) same stepper-motor around, although after testing it needed 2 times more Volt to be powerful enough.
Now it all looks much better!
The old gear setup was too much worn out, I believe. And 2 (plastic) gears before driving the arm had 1.3 mm backlash is also kinda 'too much'.

PS. I thought I tried the write action at last position in the .hal file (base-thread), but was forgotten to change the .ini file accordingly.
It does run fine now and I am not (willing) able to build back the old situation to test this again, sorry for that.

And yes, I will cleanup my configuration files after this change, the X- and Y-axis are now the same.

Regards, DG.

After installing Ventoy onto a USB, all you have to do is just copy the ISO to USB, no software, no burning, nothing.

Did you copy-paste the part about Ventoy from a post I wrote?

Looks a bit like my writing style.

I most certainly did not, i use Ventoy since it first got out, and some French version of multiboot before that.
And you do not have a writing style, you just spew things out.

You accusing me of plagiarizing you is frankly extremely dumb as you can confirm that with a 10 second search or just checking the date of the post.
You should find something else to do with your life instead of feeding on paranoia and bruised ego.
And since you keep shooting yourself in the foot, i am done protecting you from getting banned.

I'm using and recommending jss (stepperonline) ethercat servos.
if people want to live in the past that on their own time hahaha
j/k

There's lots of ethercat offerings which is nice. JMC has integrated servos and steppers. The hitch with lemontart is the fit is tight, especially for the z.

Everything it coming together though nicely. I hope in january we can start seriously working on the control aspects.

Whoever has access to the server behind linuxcnc.org/iso, please run:

for f in * ; do md5sum "$f" > "$(echo "$f" | cut -d'.' -f1).md5"; done

This will generate an md5 sum for every file in the directory.

It's so easy, why not?!

That is a looooong list !
Yet no machine dimensions, weight of moving parts, drive train, reduction, materials used, etc...
And just putting it out there, 1KW servo motors for a plasma machine is utter overkill, no matter how big or heavy. The biggest i have seen on old industrial machines were 400W, with reduction two of those could fling a probably 200KG heavy gantry at 18m/m!

This is a mod that allows using a single key to cycle through Program Run, Program Pause, and Program Resume.

I unbound the keys R, P, and S from their original commands and bound only the R key to a routine that handles the cycling.

If you’re willing to test it, please let me know if something doesn’t work correctly and I’ll fix it.

I swapped around the inputs and outputs and that solved the issue. I was able to get all the buttons to function. I spent a while working on getting the gmoccapy jog buttons to move the axis but for some reason the only way I was able to get any of the axis to move outside of homing is to use the halshow to select the axis for jogging. Tried tying the ui pins to the pos and neg axis pins. Also almost done with the pendant with the mpg just need the rotary switches and wiring

This is a mod for incrementally increasing/decreasing Feed, Rapid, and Spindle Overrides.

They behave similarly to the Jog Speed slider.

I unbound the keys `, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0

And bound:

1, 2 to decrease/increase Feed Override

3, 4 to decrease/increase Rapid Override

5, 6 to decrease/increase Spindle Override

Keys `, 7, 8, 9, 0 have no effect.

It follows the INI fine settings.

I have also implemented an exponential response to speed up changes. In principle, it works with any exponent, but so far I’ve had the best results with power = 3.0.

If you want linear behavior, set power = 1.0, and then each key press will change the value by one unit.

If for some reason a slider gets stuck at a certain value, set linear_threshold_rate to a value slightly higher than the stuck position. That will solve the issue.

It’s not as quick as a potentiometer, but it works quite well. If you want it to be even faster, try:

xset r rate 250 40

This doubles the key auto-repeat rate and cuts the delay before auto-repeat starts in half.

Try different delay and rate values. The downside is that if you set them too high, editing text files can feel awkward.

If you’re willing to test it, please let me know if something doesn’t work correctly and I’ll fix it.

By the way, this mod is derived from this post: forum.linuxcnc.org/51-ot-posts/49830-com...ntrol-console#279421
