Is 6F2 a thermal resetable fuse?
Did it trip at any time during the "incident"?

QtPlasmaC had a wizard that could convert any working config into a QTP config, no idea if it is still included so might want to wait for the developers to chime in.

Well. do you mean to only use that controller and the mentioned machine or use the Mesa 7i96s an build the cnc hardware by myself?

It seems those pics are bit outdated (or I got the wrong link. Here is the official manual:
www.cnc-step.com/wp-content/uploads/2021...-Series_Zero4_EN.pdf
Which clearly has an Ethernet connectivity (page 5 ff).

As for the "direct support" of LinuxCNC: I'm unsure.  This quote from from the specs sheet suggest so:
"Operating System with Software
KinetiC-NC, WINPC-NC, MACH3, EMC, Linux CNC:
Windows / Linux"

Not clear it it actually works with a parallel port.
it has a built in  controller with Ethernet connectivity.
Do they support LinuxCNC directly?

It seems to only have one (LPT like) connector
 

Does it actually use two parallel ports?

Hi all,

Today is activated the abc, uvw axis for the scurve planner.
It should work with look ahead.

git updated

The big problem is I never used Ncam so don't know how/what things worked before.
Some things work now but really I could use someone who knows the program to audit and prioritize what part to work on. That would help and motivate me more.

I created a branch with the updated original version, so you can have a look how it supposed to work.

You find a gmoccapy sample config running in a RIP environment here: github.com/LinuxCNC/linuxcnc/commits/nativecam
You need to run 'git submodule update --init --recursive' because I added NativeCAM as a submodule...

I created a branch with a gmoccapy sample config: github.com/LinuxCNC/linuxcnc/commits/nativecam
to test in a RIP environment.
I added NativeCAM as a submodule from github.com/freemoore/NativeCAM, so you need to run 'git submodule update --init --recursive' for the first time to get its content.
Please let me know if it works for you as well.



 

Yep. I'm thinking that there's enough copper in this machine, to cover the cost of a significant portion of this conversion.

I had a drive playing up and resetting to factory defaults fixed it
 

This is the correct wiring... I always had it wired like that, so the 7i77 and 7i84 are always powered.
 

 

When I flip the mains switch, I have 24.26V on rail 204 to ground (201).

I cut off the legs and then desoldered the remaining leg bits, removing the both NCV7608 chips. When I plug the 7i84 into the 7i77 and boot up (no field power connected) , I get a solid yellow LED on CR8, but that is all. None of the other LED's show any activity. LinuxCNC fails to load with a 7i84 pin unknown error.

Tommy, good idea to scope that 24V rail while switching some of the bigger relays, thanks. Since LinuxCNC faults out, I will need to work out how I can fake machine on and latched, to get the 200 rail powered as well, so be able to manual operate those relays with their test buttons.

I am considering of buying a cnc milling machine.
 do have good Linux experience and own a Lasercutter (which came as a set to assemble), but I am new to this kind of machines. The cnc-step support confirmed that their milling machines can be run with Linux cnc, but with no support.
I didn't had any resuls with the forum search, hence the question(s):
-Is there experience with this particular machines?
-If not, what kind of information do I need to gather about the controller to get it working?
(here is the information of the site: www.cnc-step.com/5-channel-stepper-motor-controller/)

Let me know, if this is even the right way to start my information gathering or what a better approach I should do for this.

I know Tom has already tested this chipset, but I'll add some more details.

Model: PAR6408AXX100
Chipset: Sunix SUN2212
Interface: PCIe
Supports PS/2: YES
Supports EPP: NOT TESTED
Supports IN Mode: YES (In PS/2 Mode)
Supports X Mode: YES (In PS/2 Mode - Control port pins are open drain/collector)
Tested OS: linuxcnc-2.8.4 / Debian Buster
Tested Computer: Dell Optiplex 760





For IN and X Modes to work, mode has to be set to PS/2.

I couldn't figure out why, but a couple of times during my testing the mode changed itself to Standard Mode, whitch is not bi-directional. If one tries to use IN or X modes while in Standard Mode some pins won't work. 

Does anyone know what may be causing the ECR register to randomly reset to Standard Mode (0b000XXXXX) ? If I can't find a way to fix it I am thinking of setting a startup script to make sure the right mode is always in place.
