Good evening, I downloaded and burned the latest raspberry pi 5 image and have run into a couple of problems.  The user "cnc" password "cnc" lacks root access and only has read access to the etc file.  Is there a SU password for this latest image.  I need to make some changes to the etc /network files as there is no apparent network manager showing in the available applications.  Thanks!

First and foremost, this thread is awesome; I can't wait to get in here. 

Is there any real documentation on how to implement it? Maybe I'm just not finding it, so if someone could point me in the direction, that would be great. 

Thanks all! 

Keep up the great work! 

I had tried flipping the 'final vel' as a last ditch effort, with out reading that it would result in an error and it didn't change anything nor throw an error.

I didn't even realize that was possible. Let me see if I can figure out how to do that and post it here.

At least at first glance, the hal/ini files seem OK

A halscope plot of Z position and home switch state
when homing would be helpful  for debugging.

(Perhaps triggered by the home switch state)

 

For what its worth i have been just using ssh and its been fine for most of what I have needed.

maybe ill revisit this at some point but for right now its not a priority.

Thank you all for your help, we can close this one out, not sure what to do for that.

Can i check if its, "controlling the step motor drive enable(s)"? in Halshow?

I agree that it seems like it would be a wiring issue especially considering that the driver works independently. The only evidence i have to the contrary is that i run a continuity check on the two A leads and the two B leads (at the driver on the wires coming from the motor) and I get expected behavior - > beeps when i touch the first two and the last two together nothing more. Should i just replace that wire anyway?

I was unclear, I meant how to increase the font size in those menus.

Hi Friends,

 I am pulling my hair out with the Z portion of the homing sequence and could use some help. Currently i have my limit switch as the 'max-limit' for the Z axis. Prior to pressing Home All i am able to Jog the z axis and it works as expected (- is down, is up). 0 is max and -4 is min (this might be the root of my headache)When i press home all, it searches up and makes contact, backs off, and seems to continue through the switch in the positive direction. Per the homing configuration (linuxcnc.org/docs/2.7/html/config/ini-homing.html ) this shouldn't be happening because my search and latch vel are the same sign.

I should expect it to:
1- search up in the positive direction
2- make contact with the switch
3- back off in the negative direction
4- do the final touch of the switch at latch vel in the positive direction
5- the proceed down in the negative direction to the home location.

Instead what is happening is:
1- search up in the positive direction
2- make contact with the switch
3- unsure if its even backing off
4- goes in the positive direction past the limit switch and would crash the axis 

note in these ini/hal the home offset is set to 0 but it had been at -0.5 with the same behavior.     

Unless LinuxCNC is controlling the step motor drive enable(s)
(and there is no evidence of this in the hal file),
all motors should all have holding torque when the drives
are powered. Seems more like a drive fault or wiring issue.
 

Hi Friends, 

While working on my homing sequence I encountered some strange behaior and didnt find any other posts with similar issues and i figured its a simple fix i just don't know where to start. 

In general, when plug in the power supply that powers the CNC all the motors are not able to be turned by hand as expected (i think) because theirs current to them. However, when i open LinuxCNC all the motors remain not being able turn other than the tandem Y motor. I am currently having issues with the z sequence (separate topic posted) but with the motor unplugged it seems to switch to the Y axis and only one motor turns. So it seems to me like something is turned off in my .hal or .ini.

I've checked the driver and it works and I've also double check all wires are connected. The second Y motor is connected to '4' on the mesa. 


Any advice is appreciated.

I had the link for that one. Perhaps I wandered off this thread when I found it. It was a compilation of I think all of the macros showing the actual operation on a lathe much like the video you referenced, just for all the different operations quite a good video, no idea where I found it and can't seem to find it.

Thanks
I think this video does a good job of going through the macros but I don't know if it's the one you had in mind:

 

That is a different video, however somewhat similar. For a small lathe he sure is getting good results.

I'm a bit clueless regarding the available lathe type GUI's (I'm starting with axis), what version is this fellow using?

Are those the "lathe macros" he is using?




 


I could be wrong as I am very new - only ever got my first Mesa cards the other day - for my little mill. Cnc lathe is still in planning stages. 
So, someone will correct me if I am wrong, but I think the UI used is Cmoccappy indeed with Andy's Lathemacros. 

But also, I feel like I saw and bookmarked posts about succesfully getting Andy's lathe macros into Probe Basic, which is a really swank looking UI. But I can't find that info now or perhaps it was a dream;). Anyone...?

There's been official images for the RPi5 from about Dec 2023.

It seems the error is this line:
If I change it to a straight line like:then it loads correctly.

Looking at the result it seems there are some oddities in the code around that line. The blue line in the graphic frame is the line changed above as shown in the code frame and the cut line does seem odd to me.

For fun, I did a test, I knew the result in advance.
LinuxCNC 2.9.4
Litex-CNC 1.3.4
The same file was used for the machine operation.

Debian 10 (Buster)
 

Debian 12 (Bookworm)
 

In Debian 12, the jitter is several times higher and this is very noticeable in the operation of the engines in ClosedLoop mode

 

I am attaching all the files of my 5-axis machine with the ability to work only with stepper motors, motors and an ecoder and in ClosedLoop mode. Spindle control via RS485 with a frequency converter. Additionally, the xhc-hb04 remote control is connected.
