LinuxCNC (More) lathe questions
Category: General LinuxCNC Questions
I won't comment on GUI choice(s) here - those are personal preferences. Regarding your other questions:Bunch of questions, Hopefully someone can fill in a few blanks as I formulate a plan for the lathe.
I'm using Axis for my mill and I'm completely happy with it. I'm now considering using LinuxCNC for my lathe. I definitely want to maintain manual operation capability.
Presently I have a derivative of the Clough42 ELS with feedback from the spindle and a stepper driving the leadscrew for threading. I like the simplicity of selecting various thread pitches metric and SAE electronically.
1) I don't suppose LinuxCNC has this "ELS" capability?
2) I also have DRO scales. Assuming I will use a MESA board, is it possible to connect the scales to the MESA board and use LinuxCNC as a glorified DRO without actually driving any steppers/servos?
3) Assuming for the moment I can use LinuxCNC simply as a DRO, what MESA board(s) would be a good fit for say max 3 encoder inputs and possibly up to 3 steppers later?
I have a RaspberryPi of some sort and I might try using it for the LinuxCNC for both space and $.
4) What RaspberryPI's are likely to have acceptable latency and what versions should I avoid?
I find the Axis GUI a good fit for my needs on the mill, what GUI is a good fit for lathe control?
Much appreciated.
- Yes, LCNC has "ELS" capability. Not in a turn-key configuration, but there's no reason you can't set LCNC up to act like your ELS. All the elements are present: spindle encoder + Z-axis positioning motor + configurable logic.
- Yes. And LCNC already has a "DRO" mode. See linuxcnc.org/docs/devel/html/gui/mdro.html
- You can read my long-winded post here:
forum.linuxcnc.org/27-driver-boards/5160...i-buy?start=0#292576
- I'm not an expert, but I think the absolute cheapest Mesa combination to get an FPGA card (required) and 3 axis/spindle encoder inputs & step/dir outputs is a 7i92 (any variant) and a 7i85s. You'd still need something else for IO, but that depends on your particular setup.
- If your IO needs are moderate, a 7i96s and 7i85s would get you the IO and keep packaging to two (vs three) boards.
- Based on very little personal experience, Rpi's usually have decent to very good latency and potentially not-so-good user-interface response. i.e. 'laggy' if using a power-hungry GUI. If you are using Mesa hardware you don't have to worry about latency with an Rpi.
- I've got an Rpi5 and while I'm not using it (right now), it was just fine when I tested it with LCNC and Probe Basic (no interface lag).
- Lathe GUI - any GUI is fine except Axis.

Mesa 7i96s / Network no longer working
Category: Driver Boards
Ok, this is getting weird ... Yesterday i mounted the mesa card from the lathe into the mill, all worked fine... made parts for like 3+ hours .. Today i power up the mill again and the second mesa card network is also no longer working 
I dont understand, there was zero change to the electronics, since decenmber last year or sometime around.. (added 3d-probe)
The only power coming to the mesa card is 5v from a step down converter (24v->5v) which goes into the vc+/gnd and +5 to the input common.. all outputs go to a relay board. China spindle to pwm 0-10v . Xyz-axis Stepper drivers are on a seperate 48v psu, A-axis Stepper is on the 24v psu
This setup was working for ~1 year... Is there any chance some voltage spike (iam no electronics guy ) could kill only the ethernet ?

Good evening @
my1987toyota,
Thank you for your valuable advice, I understand your explanation on the X and the Y axis. I can picture that in my head.
This Nema 23 motor and the associated driver is only hardware I have, I bought just a single one so can be familiar with the wiring and how stepper motor works.
Originally, I was thinking of Mach3, whereby I can use a cheap, around $AUD 20.00 BOB, and readily available. But LinuxCNC looks more appealing even though it is a bit more involved. I have seen videos where they run motors and spindle with LinuxCNC without any mechanical parts. I would like to take this path as well, once I understand the electronics, I will think about getting the mechanical parts.
I will heed advice and will be reading the LinuxCNC manual
I have seen videos on it but I have not done a lot of reading yet.
Thank you and best regards,
...behai.

Hello,
after diving a bit more deeply into LinuxCNC-RIO and having a closer look at the Tangbob and riocore, a few questions have come up:
1) almost every connector on the board makes sense to me, except J5 + J6 (Down/ Up) -> what are these connectors for?
2) as i get it, i can use 2 BOB's simultanously with this board, correct? Do these boards still need the 12-24V input on the right side, or is the 5V input only sufficient to drive all Inputs and Outputs correctly? Except for the PWM Output (Spindle Control) on the right side, i bet.
3) do i have to use the BOB's Inputs / Outputs (left and lower Side) as such, or can i map them freely in riocore, f.e. use the - usually stepdir output - pins P2-P5 as Encoder input pins?
4) can i power a LED strip directly via wled1 with the onboard 5V supply, or would an external supply be better?
Secondly i played around with the Tangbob configuration in riocore and as it seems i must be doing something completely wrong or there must be something messed up with the bitin/ bitout defintions for the Tangbob board somewhere:
but the latter gives a long error message when firing up LinuxCNC:
looking at riocomp.c:185 reveals:
"hal_bit_t *SIGOUT_P8 OUT_BIT" <- looks like a missing underscore between P8 and OUT, with added underscore i just get:
adding the same fix in line 541, 542 and adding SIGOUT_P8_ before OUT_BIT in line 1013 as well as uncommenting OUT_BIT in rio.hal and custom_postgui_hal, axis GUI fires up. The defined button for P8 shows up fine in GUI, i guess it won't work with hardware, though.
I tried adding bitins and outs for other boards (iceshield and octobot) and there they work fine.
All in virtuality, i still have no hardware around, but that will change soon
Cheers,
-lgitano
P.S.: Dont know if it is correct to post such userspace/ configurations issues here as this thread perhaps gets quite huge, or if it would be better to open new board specific threads? If You think so, i will do the latter
