@epineh please add you config

@Tim Bee

you need to use rio.enc0.position, this is the floating point value.

there is no raw value without scale calculation, but if you really need one, i will check to add it

Dear meister:

When I tested the encoder plugin I found that the indicated position seemed to be the number of revolutions. When the encoder rotated one revolution, the position increased by one number. I was sure that my scale configuration was correct because the rpm displayed the correct value. I let the motor run at 100rpm and the encoder plugin displayed about 100rpm. My encoder came from the simulated encoder of the servo motor driver.
 
 

As PC's said,

Your 7i96s is perfectly capable of driving at least 10 axis.

The process is
Use mesaflash to upload the 7i96 5bob firmware. That will allow you to use the additional axis.

I've done this with 2 separate installs and no issues.

Yeah, I think I saw and liked that vid last night as that's when I took another stab at finding a laptop that will hopefully work.

Btw, 1920x1080 is a must for ProbeBasic and Chris is putting a ton of work into the ProbeBasic for lathes these days - especially the conversational is beginning to look amazing!
 

See user manual, switch screen to position error display mode
look position error when running

tuning speed loop , you can change display to speed error mode, then tuning position loop

Another question, maybe not the ideal place for it, but let me give it a shot:)

Found a T470 with a touchscreen, just need seller to confirm a few things before pulling the trigger on it.
[EDIT] Done, I bought it. Will take a few weeks before I get my hands on it though. 

Anyhow, I need it to dual boot as I also need Windows for a few things. Especially to run some servo tuning software for Delta and maybe Panasonic. Now, if I need to start messing with turning things off in the BIOS to make the T470 work for LCnc (I am on Mesa cards, so maybe I don't) will that also affect the Windows partition or would that be separate? My paranoia is that somehow, I will be limiting how well the laptop would work in Windows mode. That said, I don't know if servo tuning needs anything particular that BIOS modding could mess with.

What is the goal here?

Two completely separate CNC machines?
Are you just trying to have 1 computer running 2 machines?

Just buy a 2nd computer. Second hand business machines work fine

Ahh, that may be a master only option for stepconf and not in 2.9.4

If stepconf is standalone (I think it is) you should be able to just use the latest:

 

( rename to stepconf and chmod +x stepconf )

I've done this with a CNC plasma..... It's not too bad from the linuxcnc setup side of things. The hardest part is generating the gcode to do what you want. it's not too bad (programs like a lathe most of the time).


To run the y and a at the same time
G01 y5 a180 f50 that will turn the bar 180 degrees while y travels 5 inches in sync with each other.

What version of LinuxCNC?
Does it have "tandem N axis" as a choice?
Use that if possible, there are no slaves in LinuxCNC.
Just checked and 2.10 has those choices.

Nope, not the same thing, link is to running two programs at the same time, the video is using two Mesa cards that can easily be done by LinuxCNC, as well as any combination of multiple parallel ports, Mesa, EtherCAT.
Would your situation be possible using two PC's and many IO to communicate between them with feed holds and waits and whatever necessary?

Something like this should work:

 


You may need to invert one direction
and I'm not sure if you have home switches.
( Gantry homing typically takes 2 home switches )
 

Thank you for your answer. Seems like you're everywhere haha

Anyways, I saw both, and the first GitHub Issue seems to have died down, whereas the second link talks about something much more involved, which is coordinating two systems with one program. The second link is actually something another user archieved in a YouTube video , but it's not what I need since both machines in said video acted "as one".

My machine is using the Y and A motors off a parallel port breakout board. I went thru the step config wizard and set up X, Y, and Z configuration and included the A motor pins while doing so. Im really not sure how to proceed as I need Y and A to both home at the same time? Does anyone have a solution for this application?
 Thanks in advance for your help and support!

This was mentioned before, and seems some work around were mentioned on github
