Hi, I run a Wood manufacturing company. We currently have about eight routers. We have done a significant amount of customization of our current equipment and are looking to shift to Linux CNC and build several machines from the ground up in the next year including a feedthrough four axis machine, and a CNC lathe. I’m looking for a consultant to help guide us through this process. We have an engineering team in house. We are based in Utah.  Proximity is nice, but not necessary. If you know somebody who might be a fit or would be interested yourself, I would love to hear from you.

In my opinion, Ethercat is a great solution for small machines that can use integrated drives.
I have mills where the individual axes are connected to the rest of the machine via a one patch cord and one power cord, and things like homing limit switches  or other sensors are connected locally to additional drive inputs.
Such a machine is simple to wire and, in my opinion, more reliable.
However, if all the control is to be located in one cabinet and long and multi-core cables are to be run, Ethercat loses its advantages for now. It's just expensive and difficult to set up, and what's best about it becomes secondary...

Nonsense. ethercat drives whole factories. The advantages of ethercat remain regardless of the size of the machine. Ethercat should be a more efficient protocol than mesa hm2 so it should have more efficient bandwidth utilisation. Linuxcnc won't care if you use mesa or ethercat

 

I am not sure if tcp will help here..see attached pic...maybe not clear but difference in green and yellow rectangle show difference between tool center and reusuting cut of a profile cutter where cutting edge is offset from center of tool..seems like b axis would need more z height to give correct cut on both sides of stock.
 

I hope these help! The wires pretty much go straight down from the REV A board to the PCB board. I appreciate you taking the time to help me!


 

I don't know if Probe Basic does it differently, but the probe I use with the Axis UI is configured as a tool in the tool table. The length offset then gets applied like every other tool

I believe the drive enables are wired, it's the light blue wire hidden under the grey wires in the back.
I have no schematics, and am unsure where to look.
I'm trying to figure out the wiring off the original power distribution board, which is the last picture.

Apologies for the use of improper terminology, newbie here. So, I have a PrintNC machine with Probe Basic. For the most part the setup has been intuitive, and most of the questions i've had have already been answered here. The one thing I'm a bit confused about is probing, I have a tp06 probe, and I've been using it to find corners, bosses, bores etc. So one of the settings is the tip diameter of the probe, which is perfectly clear to me as to why it's needed. The one thing I cant figure out is, isn't the height of the probe also needed? In my mind, i can bring the spindle (no tool) down until it touches the spoilboard, and record the Z height at the point (Z0). Then I cant put the probe in the spindle, and lower it until the spindle touches the spoil board and record that Z (Z1). From there the probe offset is Z0-Z1 (or the other way around), My question is, where do i configure that probe offset? is it a variable in the .var file?

Good day.  I've created a PyQt6 app to convert an image file into rasterized M67 gcode output.  It renders .svg files to 16-bit depth; check it out:  github.com/mj1911/img2m67

 

Try apt install r8168-dkms
You have to enable  non-free tree in sources-list.
As I wrote above, sometimes it not works with some kernel versions, but can work with the previous or next version (it means, for example, 6.12.xx not works, but 6.12.yy works).

Which driver should i go for?

The command "lspci -nnk | grep -iA3 net " 
tells me i have a "RTL8111/8168/8211/8411" , i read something about changing the driver to the 8168, but i'm unsure..

Other thing, if it is a bit thing to get it running, what do you think about these small computers for LinuxCNC?
They are not too expensive..
Lenovo tiny M92? Which CPU would you recommend at Least?
I learned the hard way to get a INtel-Networkchip, so i will definitly have an eye on this!

Hi Cmorley

I've done some more work on 3pcenter.
If you're interested, I have either a very minor fix for one function:

   def goCenter(self):
            c.mode(linuxcnc.MODE_MDI)
            c.wait_complete()
            c.mdi('g53 g0 z0')
            c.mdi('g54 g0 x'+self.dataX+'y'+self.dataY)
            c.wait_complete()
            self.w.pushButton_5.show()

or a fix for the entire file. It's more resilient to user errors.
X0Y0 can be executed at any time and from any position.
Test it if you like.

Hi!
I am trying to add the Mesa 7i97t card into my Anilam 1100 and I am so confused. I have (hopefully) wired the three servo drives and the rotary encoders correctly to the card, but I'm lost on what else needs to be connected. I'm specifically trying to figure out this group of 8 wires running from a PCB 801 board to a 90100289 REV A board. From my searching, I believe the 801 board needs to stay and the REV A board is the one I'm trying to take out, but I'm confused on where the wires go into the Mesa. I believe they go on TB5, but I'm lost on the order/what they do.
If anyone has advice or can point me toward a guide or something, it would be appreciated!!
