Raspberry Pi 4

Another update, its been real, a bit too real here.

First, they've installed the stent to expand the clearance needed to get the new valve installed, and my next visit is on the 11th of December to see if they now have adequate space to inject the valve. I'm feeling moderately decent in the meantime, but did find out I can't pickup up a BS-1 indexer without building a skyhook, the biggest part of it is 56kg. I did get it 3 feet from the shipping box to inside the garage door and out of the weather, where its still sitting.

In the meantime, my mobo on the main machine, this one, shorted out a usb breakout cable at the motherboard connector that took a fire extinguisher to put out, stinking up the place something terrible, so I had to drag an old dell out of the midden heap in the garage, did some email but not enough memory to get on here and post about it. But the mobo has now been replaced with a bigger, better one with 32G of dram, a 6 core i5 cpu running nearly 2x faster than the old phenom, and my web page should be accessible again. Goto my web page, add lathe-stf to the address bar, and see linuxcnc4rpi4 in the list and click on that, its all prebuilt for 7i90HD/7i42TA's for interface card's and probably works with the 7C80 family of cards too.. There's a huge 4.19.kernel image there too, see Big Johns install instructions, works pretty good as an rt kernel. So help yourself.

So I'm still sucking air regular. More than I can claim for the missus, this colder weather is taking her downhill. COPD.

You are going to have to setup the hal file manually... there is an example using gpio... Hmmm

at the bottom. Remember the GPIo pins in hal are actual pin number on the header (not the rpi numbering)

Hey guys, I have been working on getting my pi 4 setup to run linuxcnc through parallel port but I am not sure how to select Step and Dir from the options provided. What should I be selecting to setup the axis? There is no option for step and dir so I am assuming it should be something else but I don't want to try all of them. I appreciate your time and assistance.

Thank you for the quick reply. I am assuming I can add just the last two declarations right? Or do I need to put everything in that example in the Hal file?

Gene,

Wishing you the best on this journey! Sounds like a move to warmer weather may help.

Thank you for all your work and assistance. I visited your site the other day and couldn't get through. Since you have updated it I will give it a shot again.

I modified the Hal file under the linuxcnc folder to include the gpio declaration as posted earlier. I have always gotten a hostmot2 error but ignored it because I don't plan on using the mesa cards due to size and price. Due to this, linuxcnc is pulling I/O cards from the firmware and making me set up a mesa card even when I deselect it in the beginning of a Pnconf wizard setup. How do I disable that or modify the Hal so it isn't an option for me? I am not sure what I need to remove or add. I would like to use a BOB through parallel port to communicate with the Pi. I am using the image that was provided earlier by Spacehitchhiker42 on page 13. (drive.google.com/open?id=1JbPiXr_i8be1GWVPG8PJmr7NlOo6WpKD) this is what he posted. I was going to start over again with what Gene posted above but I am not sure if that would get me any closer.

One more thing. The stepconf also doesn't work. How can I fix that?

Whats your ipv4 address, I'll make sure iptables isn't blocking you, I've had quite a battle with the bots and since they change addresses nearly everyday, I've taken to using the CIDR /24 format when I block one. Not all are bad, I don't mind the indexers, but quite a few try to mirror it, and will come back the next day for a fresh copy. Do that enough times, and I'm DDOS'd for upload bandwidth. Its only a 10 megabit circuit, so about 350k/sec upload and my pipe is full.

So give me your address and I'll make sure it will clear.

If you intend to use a parallel port then you should use stepconf rather than pncconf

Okay, since it isn't working do I need to get a different image?

Here you go: 10.72.13.141.

Thank you!

Nope, not on the block list. Should be good to go then. Add /lathe-stf to address bar and you should then see a linuxcnc4rpi4 directory to click on.

Okay. I will try again at home. I am at work and the firewall is most likely giving me issues.
