Touch resizing of gcode preview was created by Fixenty

Touch resizing of gcode preview

Category: Gmoccapy

Hi, I have an issue in Gmoccapy.When I try to click on “Clear Toolpath” or “Jog Speed –”, the cursor automatically grabs the edge of the preview window. Instead of clicking the button, it starts resizing the preview window.It feels like the preview window border has priority over the buttons, so I can’t reliably click them. Has anyone experienced this, or knows how to fix it?

@Hakan certainly a stupid question but I did not understood why you did not managed to get the encoder work on the ethercat devboard here?



I wanted to test the encoder on the devboard before doing a custom board
Thank you for the clarification

program exceeds machine maximum

Category: General LinuxCNC Questions

I have my MAX-Z-LIMIT set at 20mm & MIN-Z-LIMIT set at -255

Usually when I run a program, as I set home and stuff like that manually I'd home to a mark on the column, then bring the tool down to a height of 6.35mm above the stock, set by a pin, touch off at that height. Which sets the Z zero on the stock.

LinuxCNC 2.9.3 .xz image for RPi 5 is not available in the ISO directory

Category: General LinuxCNC Questions

Unfortunately the 2.9.3 image you refer to has been removed from the server.
There is a new image that has 2.9.7 and is much more raspios like.
The thread is here which has one image suitable for both the 4 & 5:
forum.linuxcnc.org/9-installing-linuxcnc...trixie-images#338181

As this is an experimental image I would be very interested in feed back.
If you need to install probe basic there are 2 extra packages to install after following the Probe Basic install instructions:
forum.linuxcnc.org/38-general-linuxcnc-q...-launch-issue#338654

If you are not installing Probe Basic there is no need for these packages.

program exceeds machine maximum

Category: General LinuxCNC Questions

Hi, this is my first post outside of the Ethercat section.

I'm getting beat up by a z axis travel limitation, although I did somehow get the program to run once. My understanding of the problem is that my g54 is in the wrong spot. 

Fusion 360 says the max Z height is 0.6", so I moved my Z axis almost all the way up, then set the G54 Z position to 0.6". I did have the program run once, but then I stopped the program. When I go to re run the program I keep getting the same z axis error.

I've attached some phone pictures.

And one more question. Can I use the same encoder for both feed and MaxVel? I don't really like the two-button operation for feed control

My maxveloverride isn't working. It's on enc3, and spindle override and feedrate override work there, but not maxveloverride. Is this due to gmoccapy? The entries in the HAL file look the same as for spindle and feedrate.

problems with Y-Axis, elliptic deviations after several changes -Probe Basic V.5

Category: QtPyVCP

Ok 500 is fine. I knew it is 1000 for 1 ms but not how it scaled.
I was looking for a reason for the following error.
Since the feedback comes from the step generator and not the actual machine,
it seems to me the step generator is to blame.
You get following error even when running in air, right?
Basically linuxcnc, or perhaps the step generator, generates the wrong tool path in Y.
Unfottunately I don't know how to fix it.

LinuxCNC 2.9.3 .xz image for RPi 5 is not available in the ISO directory

This image was previously available, but when I tried to reinstall it, I couldn't find the specific "
.xz" file anywhere in the ISO index.

Looking for a freelancer to assist in drawing schematics for cnc plasma table

Category: User Exchange

Here is a link to the thread of me documenting the process of building the table to get to where it is right now. Yes the motors are overkill but they are not really too big of a form factor and the gantry estimated weight is 400-800lbs. I have the machine geared to run 700ipm rapid if I remember correctly. Alot of force required to rapidly change directions at fast cut speeds on a gantry this large. And yes the list is long. Really I need help documenting and planning this project to speed things up. Draw a wiring diagram and point me in the right direction for parts. I want a diagram so its easy to fix for the next guy, and I can make sure then that everything is properly grounded/bonded and resistant to interfearence. The only thing I forgot on that list is a circuit for e stop maybe using a saftey relay and I may add in a lube pump to pump oil into the tracks and rollers.

I would like to know how to connect GPIO to LinuxCNC’s E-Stop chain.

Category: Basic Configuration

Personally I would have the estop connected via Normally closed switch, and the estop is signaled via opening connection. This way if, for whatever reason, the estop wire is broken or falls off either connection the machine will go into an estop condition.
The way you have your schematic, you'll only know that something is wrong with the estop when you go to use it.
I'd rather a failing estop not let the machine run.

I would like to know how to connect GPIO to LinuxCNC’s E-Stop chain.

Category: Basic Configuration

Depends on what the machine has for an e-stop chain and that is wired, but for small machines that can not do much harm, a simple and single input and a single output are all that is needed:
# --- ESTOP-EXT ---
net estop-ext <= [HMOT](CARD0).7i84.0.2.input-14
net estop-ext => [HMOT](CARD0).7i84.1.1.output-08
That will just loop back the e-stop signal from the button to whatever is connected to the output pin. This works perfectly well on most machines (example is from my 3.5 ton Mazak lathe) as the output is wired to existing e-stop loop on the machine.
That will not allow the machine to come on when the button is pressed and will allow enabling the machine when button is reset.
E-stop latch should be used only when more logic is required by LinuxCNC, and/or more inputs and outputs.

That's what I originally thought (onboard looking after making VIN a safe value from VFIELDB) but the more I looked at it the more nervous I got.
Thanks for the verification
