In case you are interested how this came along:
github.com/LinuxCNC/linuxcnc/pull/2896

In fact I said it should be set-able and then never followed up.
You must load very big files - do you see the bounding box show?

There is a signal missing from gcode_graphics to MainWindow - I'll add it back soon.

Hi,in the terminal ,while I used "ethercat sl" command ,it did show up connected to DM3E-556 but while I used the control panel such as axis ,it can't control the stepper motor to rotate.I guess the problem may be due to .ini or hal and xml file ,but I dont know how to config it correctly .I looks that it 's much more complex to config the open-loop stepper motor comparing with the servo motor.do you have any workable .ini/.hal/.xml file of the open-loop stepper motor ?

Since when does Mesa manufacture a 7996S board?
-
1. that should usually take 1-maybe if i stretch it-5 seconds, so something is not OK
2. Prabaly still not implemented to use step/dir for spindle, so for testing maybe use it as axis/joint
3. that power supply should be OK for the test, set it to 18V and limit the current to 1A, turn it on while holding the motor shaft by hand, if it moves a bit and locks so it takes a bot of effort to move it, continue to calibrating it, if it is to weak to notice - raise the current to 3A and try again.

Went through the g code could not find a g64.
I am running 2.7.15
My photo is too large, will work on that.
THankyou for your help.
I thought of something in kirimoto that might make a difference but not certain exactly how it works yet.
 

Yep,  cable 26 HDR end put on backwards.

Good catch tommylight.
 

If you feel adventurous download Ventoy, install it to a USB, then just copy ISO files to that USB, it will find and present you with a nice menu to choose from when booting from it.
Very easy to set up, and saves huge amounts of time for me as i install a lot of everything very often.

1 picture only.
And this is a bit confusing, racetracks are created by the cutter, so not a software issue, but rounded corners can be software issues, namely G64 Pnn where nn is the amount of allowed off track motion, so G64 P0.1 would follow the line with a tolerance of 0.1mm (or 0.1 inch if the machine uses inches).
You should add that to the ini file, startup G code, section and set the CAM to also output that before every part cut.
What version of LinuxCNC are you using?
Edit:
Round tools can not make square corners, so if the corner is the exact end mill radius, all is good.

The cable/connector on the 7i92 side looks reversed, pin1/red wire should be on the other side.
7i76 side looks ok.

This is valid for configurations created with PncConf wizard, you did not give any info on the actual hardware used nor software.
Make a copy of the existing config and put it somewhere safe.
Edit the .ini file with a text editor:
display section change GEOMETRY = XYZA to XYUV
TRAJ section change COORDINATES = XYZA to XYUV
change [AXIS_Z] to [AXIS_U]
and change [AXIS_A] to [AXIS_V]
save, do not close the text editor, you might need to go back with CTRL Z
The hal file needs a bit more care
change
loadrt pid names=pid.x,pid.y,pid.z,pid.a
to
loadrt pid names=pid.x,pid.y,pid.u,pid.v
-
then
addf pid.z.do-pid-calcs servo-thread
to
addf pid.u.do-pid-calcs servo-thread
and
addf pid.a.do-pid-calcs servo-thread
to
addf pid.v.do-pid-calcs servo-thread
-
then everything under the section "AXIS Z JOINT 2" and "AXIS A JOINT 3" wherever there is z in any line, replace with u , and wherever there is a in the line replace with u .
DO not use "search and replace" feature for this, it will mess up the configuration beyond repair.

Hi tommylight,

Thank you for the suggestion I just tried this with Rufus. I got the live version to start now, so I decided to move onto the installation. This is where I landed on:
"installation step failed ... The failing step is: Install the system".

I actually got here before, when I tried making the bootable USB with 'startup disk creater' on ubuntu. Figured this was incorrect and moved to the steps as described in the guide.

pressing ctrl alt f4 showed some strange logs.
'cant open blockdev'
'the tar process copying the live system failed'
'xz decompression failed'

will try tomorrow with the new USB stick and some different rufus options / win32diskimager. Current USB is too slow in writing for doing this repeatedly.

What you show is OK:net lube-ps-float-sw  <= hm2_5i25.0.7i77.0.0.input-09
net lube-ps-float-sw => oillow.trigger
There must be another connection to hm2_5i25.0.7i77.0.0.input-09
elsewhere in a hal file
 

Afternoon All.

I recently built a cnc table. I made a plasma table years ago and had no issues, router adds a few more dimensions, now I am confused.

My issue is the cut path is an oval rather than squared corners. I use Kirimoto as my slicer, it shows square corners and the animation gives square corners. Move the file to my cutter and it also shows squared corners in the preview. When I cut, the corners become rounded, exception of one corner where the tool always moves to the next x y z start position.
I am including two photos, one is a cut track as shown on linux the second photo is of a different file and shows the actual rounded corner, opposite end of the cut is completely rounded.

Any thoughts?
 

thank you, it works perfectly.
But what's wrong with my programming?
Because I have the same problem with the message.comp"hm2_5i25.0.7i77.0.0.input-09 is already link to lube-ps-float-sw"

Shorts, opens, off by one errors would be the most common

Do the 7I76 step/dir outputs work?

Hi all

My hot wire machine is working, but the software I want to use (devFoam) issues X,Y, U,V parameters for G1 (four parameters on each line). I am not cutting tapered parts, so the U value is always the same as X, and V the same as Y.

I don't want to modify the gcode manually. My breakout (parallel) board is marked for X, Y, Z and A.

Can anyone help me with how to configure this?

Thanks
Garth
