I did not know those even existed


back when machines had no memory things were different. my Maho had all sorts of interesting canned cycles for complex motion that you would not have the memory to hold in a program.

"Side note - rodw's mention of rail extensions used as way cover mounts is right on the money. This is exactly how my mill's front Y-axis and Z-axis cover ends are mounted."

physically mounting the way covers is a non issue for me. my main problem is simply making them fit. this machine is really small and extending 100mm for way covers each side actually adds like 30% to the machine length. Don't want that.

I run mist/mql. wont get flood.

I expect the nylon to swell, I don't *think* it will be an issue in these uses, but we will see soon enough. I don't have any sls parts handy to test on right now. Nylon SLS is the cheapest print form services except SLA resin which is usually not acceptable for these uses. I could definitely print the atc hat on my printer here from abs or petg though.

You may find them on Amazon but I dealt direct. So many mounting options now you have a size in mind. 

Despite planning to buy used - I can tap into a vast secondhand market in China with their domestic apps and have bought the router and everything else there - I had a look at Greentouch's website. That does look to be a great source. Every conceivable size under the sun.
I've seen comparable brands and models on Taobao "Chinese Amazon" so have a pretty good idea about that they will cost.

I've also come across a ton of All-In-One touchscreens with PCs built-in. But since this is my first ever foray into Linux, Lcnc and actually my first PC in 15 years, I thought I'd stick with a known brand for the PC. At some point, I'll probably CNC a small lathe and then with the the experience I've gained on the router project, perhaps I can be more adventurous. 

Does anyone have RC Servo Test for a Mesa card setup similar to this older tutorial?

RC Servo Test

I tried using MesaCT and the only PWM output was the spindle, so I tried that.  I get an error something like SERVO_0 unknown.  So Im probably not setting the PWM channel correctly.

My PWM channel is on the BOB connected to P1 on the 7i96s.  Any help is appreciated.

Cant do this anymore bye all wrote:

Sometimes you can save a bit of cash using a freight forwarder.
I've had very good service with shipito getting stuff Down Under .

Hehe, yep, need a Mesa mule:)
Might have to use a freight forwarder, but since I live in possibly Asia's best/biggest freediving hub, we also have US divers come in from time to time. So, will start asking around. 
Oh, didn't know you were Aussie. I always feel for you guys when I hear how much stuff costs once it finally gets to you. 

 

I'm not actually sure who owns the EtherCAT package, but I sent email to Bjarne about it, hopefully he can help get it to the right people.

We should really modify the EtherCAT package to install these automatically, as it's a common problem. Presumably we'd want to create an `ethercat` group and use it in udev instead of giving EtherCAT access to everyone.

All good, I figured it out.

It was running very accurately with the old controller (RichAuto B18) - and I did not touch any mechanical components when switching to LinuxCNC. That's why I ruled any bad mechanical components or connections out.

I changed the orientation of the part I was using to test error by 90 deg and got worse error. I may just run through a new setup of LinuxCNC and see if that will fix anything.

I'm happy with homing the axes, I just want to add a button using gladevcp that will set all four once I have jogged the wire to where I want home to be. Not at all important, just being a bit pernickety

Thoroughly check the mechanical side, like every single component. More often than not that is where the problem is.

Hey everyone, I am having an issue where isolated analog output is failing to control my sherline spindle. This issue started after I added a spindle encoder. However, there are other issues going on that make me think there is a serious issue in my ground circuitry. I did a crappy job and there are probably lots of ground loops. Despite removing the encoder, I still get spindle control issues. As it stands, both axis work fine. At one point prior to encoder, everything worked fine.

What makes me suspect a (Dangerous) ground issue - is that moving around my isolated DC power brick (Which hooks into spin- and spin+ to get me my 0-10v range) can sometimes cause the spindle to turn on.

Currently, both axis work fine.

Therefore, I am planning on redoing my wiring, particularly when it comes to ground circuitry. I made a diagram of the new proposed ground circuit and wanted to see if anyone could verify this should work correctly.

My biggest question for this is: Does step- and dir- connect to GND on the steppergen of my 7i96s, or to the ground bar that connects to the sherline frame?

 

For Linux to Linux file sharing forget about SMB, setup NFS.
Use SMB for Windows to Linux.
NFS is easier to setup on both the client & server side.
This site has awesome tutorials
www.digitalocean.com/community/tutorials...ount-on-ubuntu-22-04

Windows NFS client is also an option, tho being an exclusive Linux user I have no recent experience with windows .
