The approximately +- 15000 encoder velocity numbers in the video
seem like pure noise. (and negative values should not even be possible)

I would first try jumpering the 'B' input as single ended and see if that helps
(also make sure nothing is wired to either 'B' input)

Do you get steady arc voltage readings when the plasma supply is off?

So as it turned out we have lots of IO on the drives. 24 in and 6 out. So really It will be down to figuring out the spindle. RS485 is an option on the drive, but I know virtually nothing about how that works. Anyone got a link to some "for dummies" instructions? and whether it will work alongside ethercat?


 

I’m sure it’s something very simple that I have got wrong. 

last night I realised that I don’t have an arc ok showing when the torch fires. Checked wiring and it’s all correct. 
Cpc pin 12 goes to input 10 on the Mesa, pin 14 goes to common +. 

We are humans, and as such we all have our ups and downs.
Hence, it's also human to restrain when someone else has a bad day as not to amplify whatever hardship they are going through.
As for spammers, they do damage, actual damage, as clicking on some of those links will literally grant them full access to your PC and everything on your network, yes even cameras, followed by misusing whatever info they got out of your systems and then some will add extortion to that threatening with making that info public. Or completely locking you out of everything, and extorting you to get your own stuff back.
So calling us names here and a bit of cursing and swearing just makes this place more "colorful"

No idea really but maybe you have active G92 offsets.
To clear run this in MDI:

If that does not fix it we would need to see your the .ini file of your machine config.

Do you use some special double-quotes around D1, D2,D3 and D4?
Replace them with the normal ones, that are around 0,1,2,3 in slaves
names="D1"

Hi,

I've tried to re-install my system (Dell Optiplex Athlon, Dual Core 4400+, 4 GB. Parallel Port) via Live CD. This didn't work at all on my system (sadly I didn't take a screenshot of the failure message but it was the step after partitioning the hard drive). I tried the same with a 2.9.3 Live CD and this was immediately successful. Afterwards I could flawlessly update to 2.9.4.
Linux was up and running as expected. I ran stepconf wizard to create a machine config and afterwards replaced it by my backup config files (2.9.3) to the created folders. My machine was running without any issues.

I then started stepconf wizard (2.9.4) to check my setting of my backup config from 2.9.3 and got an error message:

 

Is there anything i need to do to update the 2.9.3 config file to be used with 2.9.4 stepconf wizard?

Thanks in advance for your support.

Dieter
 

Never used it, but i did use VNC always, well till some 8 years ago, now i sue nothing of such sort.
There are several versions of it though, so check for the fact that the same version works on Linux and Windows.

I just figured tommylight was having a bad day.

tommylight, I remember those posts I couldn't believe he wasn't banned at that point because of how
he was acting. I think we are tougher on spammers then people were on that guy.
 

Please don't open new threads about the same topic.

Please continue in your original thread which I renamed to be more descriptive:
forum.linuxcnc.org/38-general-linuxcnc-q...-x-and-y-axis#320525

Thanks

I just had this problem where it says Program exceeds machine maximum X and Y Axis. I cannot figure out why it is saying this i’ve had the CNC PLASMA CUTTER (5x10) for about a month and never encountered a problem like this. I have a few pictures! If someone can help please let me know, thanks!!

Moved here from your other thread which I locked.

Please continue here.

Decided this should be its own thread to not get all buried in the main one.

Trading for some ethercat servos this week so I'm going to make a whole separate new control for testing.

Drives are omron RD88 400w and 200w models. 20 bit incremental encoders.

They do seem to have at least a couple IO on each one, but I think I definitely need more IO. I did have an EK1100 somewhere, but I cant find it and it would cost a few hundred to get the IO modules, especially spindle analogue.

Does anyone have a link to a low cost IO module that works well with linuxcnc? I've seen a few floating around, but I have no idea if any of them "just work".

 

User manual section for the python stuff:

linuxcnc.org/docs/devel/html/remap/remap...i_file_configuration

Create a subfolder in your config folder named 'python.'

Put remap.py, stdglue.py, and toplevel.py in the new 'python' folder.

An example can be found here:
github.com/LinuxCNC/linuxcnc/tree/master...ython-stdglue/python

The change_prolog & epilog stuff are contained within the stdglue.py file.  What the "REMAP=" statement in the INI file is doing is telling LCNC:

• When LCNC sees and "M6"
  • Look at toplevel.py and import (use) everything in remap.py
  • Look at remap.py (import stdglue.py)

Look at stdglue.py and substitute all the "change_prolog"  and "change_epilog" sections for LCNC's built-in behavior

And the ngc=Tool_change_sub section is telling LCNC to substitute that file (i.e. do whatever is in the file) for LCNC's built-in behavior.

EDIT-

Forgot to add... you also need a [PYTHON] section in your INI file if you don't already have one.  That 'TOPLEVEL=' part tells LCNC where to start looking for everything.

[PYTHON]
PATH_PREPEND = python
TOPLEVEL = /your config folder name here/python/toplevel.py
PATH_APPEND = /your config folder name here/python/
