I use sheetcam and the addons for CandCNC electronics and software. Sheetcam does have a tab feature and could be used to keep parts from tipping up. You can set how many tabs and what size to use, so a single tab that is small might do the trick, but I have not used it for that purpose. You could make a dxf of your slat table and have that as a locked layer in sheetcam, then move your part where needed. My slats are 4 feet long and are set with a bow of 2 inches in the center so I don't worry too much about where they land. Ramp and wiggle lead ins are also an option, but I don't know if that is stock sheetcam or part of any addons from CandCNC. Sheetcam does calculate cut time with the simulation and it used to have a report feature that would tell you how many inches of cut, how many pierces it had, and the time to cut.

Inkscape certainly isn't cad or cam software and I only use it when I need to do graphics type work vs. geometric lines that are easier on cad. For cad, I use siemens solid edge community edition which is a free version. Businesses with the commercial version can not open the files from the free version, but it is fine to save as a dxf and import into sheetcam or fusion 360.

Yes, sneaky buggers charged my card on the renewal. Wasn't planning to.
I've only done one job in the last 12 months......
All my parts are sheetmetal and laser cut these days (or made in India or China), inserted about 300 nutserts today. Thank god I have a pneumatic tool!
 

Crap that suck. 300 inserts yikes, how long before your hands stopped vibrating?

So much for AI replacing everybody. I guess that would stand for Algorithm intelligence LOL

Should we nail it ...hmmm pin it ?
And adding the download link would be good.
Thank you.

The documentation is outdated, try clicking on the colored channel buttons on the bottom of the screen to toggle channels on/off. Eg the red button with '1' on it.

Hi Aciera, thank you. I have just now re-run it. It works as you have indicated. Best regards.

Oh you found that....
Been editing the damn thing since yesterday afternoon, copyright claims all over as i can not work without music.
I must say, it did a good job of removing music and leaving my voice and other sounds still audible.
But takes ages, currently the 4th is getting edited out, i have 5 or 6 more to go.
Still, it does play consistently despite editing in the background. At least something works properly on youtube, given that the algorithm is a total disaster, very iffy and extremely bad at figuring what to show me on "new to you", it has a 2 o 5% hit rate. No wonder tiktok is wiping the floor with them...

First lets talk about the images.
1: They are based on Debian repos built by a collection of custom scripts.
2: Whilst some images have been written to SD card via RPi Imager Balena Etcher is recommended.
2a: If you use Linux there are plenty of other tools, Ubuntu\Mint has USB Image writer.
3: If you use the RPi Imager any adding of user or wifi info does not work. As the image is a custom one, only the kernel is built from RPi Sources.
4: If you are using an Rpi5 & a 7c80 0r 7c81 the driver to be loaded is hm2_spix
5: If you are using an RPi4 & a 7c80 or 7c81 the driver to be loaded is hm2_rpsipi
6: The images now have the SPI interface enabled by default.
7: Location of config.txt  /boot/broadcom/config.txt once again this is a custom build.
8: raspi-config is not in the image, the tool to use is menuconfig.
9: The default username is cnc.
10: The default password is cnc.
11: The images are not meant to be a fully fledged daily driver Operating System, the are just enough to run Linuxcnc.

Why don't you document what you did ?

hmm seems to work in my tests now.

Thanks Tom I will give those video's a look after I finish watching you build your computer. LOL


 

That fixes the display, but doesn't allow spindle synchronized motion.

The way to fix this is to set the encoder scale to -180

I have a pretty convention setup (I think) with a Huanyang VFD connected via RS-485. Before switching to RS-485 controls, it worked fine from the control panel (on/off, fwd/rev, speed, etc.) but now that I've switch to RS-485, I cannot control the speed. I CAN turn the spindle on/off and set the fwd/rev directions from the Axis GUI. When I press the + and - buttons, I can see the speed changing in the "Spindle Speed:" GUI, but the spindle itself does not change; it's always at the minimum.

Here's a screenshot which shows the GUI, custom.hal, and some HAL display from Axis.

custom.hal:
loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600
#type, name              val: source           >  destiantion
net  spindle-cmd-rpm-abs spindle.0.speed-out   => vfd.speed-command
net  spindle-fwd         spindle.0.forward     => vfd.spindle-forward
net  spindle-rev         spindle.0.reverse     => vfd.spindle-reverse
net  on                  spindle.0.on          => vfd.spindle-on
setp vfd.enable 1

Any ideas here?

Thanks


 

As an FYI I tried this and it doesn't allow the spindle to increase or decrease.
