A Treatsie on the Parallel Port - HP Elitedesk 800 with generic cable

Category: Installing LinuxCNC

On a lark, I tried something... I created a new profile for XYZ and a second new profile for XYZA (I think I also set the XYZA one to mm, whereas I forgot and default to inch for XYZ).

Amazingly, on the XYZ profile, Y and Z worked perfectly, X didn't work at all. This isn't a shock because the default values for X put it onto my A. So I hand edited the HAL file, and changed X to be on pins 16 and 17, and...

EVERYTHING WORKED!

So basically, at this point, I think I have a working system and just need to tune the .hal and .ini files (or learn how to do it). When I looked through the original file I had generated ESTOP_ON was ONLY on pin 1, not on 8, 9, and 14 -- so that explains why they never went high.

Thank you so much for nailing the problem in one comment, PCW!
Thanks for sticking around and constantly pointing me toward the finish, Cornholio!

Other things to check:

1. Do you have an Intel or Realtek Ethernet chip?
( there are chip specific things you can do to improve latency)

lshw -class network

Will list your Ethernet (and wireless) network hardware if you are not sure

2. Have you run a simple ping test like:

ping -i .2 -c 4 10.10.10.10
sudo chrt 99 ping -i .001 -q 10.10.10.10

The first command populates the ARP cache so the ARP lookup doesn't add time to the first ping
The second command should be run for a few minutes (and then stopped with a control C)
and the results posted here.

Hello! I want to build a plasma cutter and am still very new to Linux. I created a test setup with a Thinkcenter, 7i96s and thcad 300. I think I have configured everything well. I also connected a stepper motor for testing, which also rotates at the correct speed. The only thing that bothers me is that in all the videos I find the burner position is shown, but mine isn't. Does anyone have an explanation/solution for this? But it's only in QTplasmac. If I use the GUI Axis then I can see the position. I hope it's just a small setting.
I installed it according to Talla83 from YouTube
uname -a
Linux Linuxcnc 6.1.0-18-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.76-1 (2024-02-01) X86_64 GNU/Linux

I've come up with something new. When I start the program I see the machine table with the limits but as soon as I press Home or something it disappears and I can no longer see the size of the machine table

Hi Everyone, 
I have just installed Probe Basic on my milling machine computer and I am wondering do I just run the PNCconf to get the folders and then just copy my working configuration from my original Linuxcnc to the Probe Basic folders?

Thanks

sherline ballscrew lathe moving 0.99mm for each 1mm...linux or machine issue? was created by ffffrf

sherline ballscrew lathe moving 0.99mm for each 1mm...linux or machine issue?

Category: General LinuxCNC Questions

I am running linuxcnc 2.7 for a sherline ballscrew lathe that I just received. They had a disc that came with linux 2.6 but I opted to set things up on my own with stepconf and a parallel port adapter. I hooked everything up and got it all working but am getting a puzzling issue...For ever 1mm I move in Gcode, the machine moves 0.99mm. This means if I move it 5mm it end sup at 4.95, and if I move it 10mm it ends up at 9.9 and so on and so forth. I am using a perpendicular dial test indicator and this is for the Z axis. This would not be typical backlash behavior.

My question is...is this a lathe issue or a linux issue? I am using the sherline high torque stepper motors which are branded as "anaheim automation 23y204D-LW5-01"


EDIT: I used a better dial indicator and the problem was not as bad as I first thought HOWEVER - what I am noticing is that the lathe actually moves shorter only in the forward direction, going backwards it ends up dead on. But no matter how I change my backlash adjustment it does not fix it

EDIT#2: could it actually be due to my dial indicator not being perfectly perpendicular to the saddle?

I borrowed .ini file settings some from the original disc and others made through the stepconf. 

-it is hard to find specs on sherlines ballscrews but I found that they said it was a pitch of 2mm

-I have only texted axis #2 so far (in the ini file)
-I purposely # out the backlash comp as I realized it was not backlash


Stepconf settings:

Driver microsteps: 2 (dont know where to find this online for my steppers, so kept generic)
leadscrew pitch: 2mm
pulley teeth: 1:1

open a terminal and type
sensors
see what temperature the CPU is at while LinuxCNC is running, anything above 60 degree C should be mitigated by re-pasting the cooler or replacing the fan or with better cooling.
Some processors will handle over 90 degree, some Intel Xeons will throttle badly at 63 degree only!

Error finishing read! Iter and joint following error in Stepper machine

Category: General LinuxCNC Questions

Trying to fix hardware issues with software is never a good idea, so ini file settings can not help much as you already have the servo period set to 2 million, but why oh why did you set the P value for all axis/joints at 1250???
Set those at 500, they are servo period dependent and must be 1/servo period, in your case 1/2000000ns=500 or 1/0.002sec=500

What PC? did you disable power saving options in BIOS? did you disable hyperthreading, TMP, C states, etc?
Also, open a terminal and type
sensors
see what the CPU temperature is while running LinuxCNC, anything above 60 degree should be checked and mitigated by repasting the cooler or better cooling.

Error finishing read! Iter and joint following error in Stepper machine

Category: General LinuxCNC Questions

Hello guys
i am getting some errors related to stopping the movement of the axis suddenly with a Error Finishing read and joint following error although I have a 2000000 servo period.

is there anyway can I improve my ini file to get over this?
would it be ok to increase servo period further?

thank you

Also ich hab zwei verschiedene Touch am laufen, ebenfalls an Lenovo ThinkCentre.
Einen 15" und einen 21"
Installieren musste ich bei beiden nichts.
Das USB Kabel hast du schon eingesteckt?
Versuch mal einen anderen USB-Port am Rechner, da sind nur zwei direkte Ports, die anderen laufen über einen Hub.
Kann sein das macht Probleme

Hello, I'm trying to configure ATC, currently I have a manual tool change with sensor approach.
[RS274NGC]
PARAMETER_FILE = linuxcnc.var
FEATURES=30
SUBROUTINE_PATH =  macros
REMAP=M6    modalgroup=6 ngc=tool-change

How can I configure LinuxCNC so that before measuring the tool, Linux moves over the selected tool.
Tools in a linear warehouse. I don't know what to add to the RS274NGC section. 

Thank you for every helping hand :)
