M6 shuts off spindle, but no UI confirmation, and program doesn't pause

Category: Basic Configuration

something to try - switch to relative moves, then G1 Z0 ? Even though you're not moving, it may count as a wait point for M3
Or use M66 instead? You could hook that up to a button near the spindle, or a GUI button.

Is the PV raw count?
Is the index some input?
Where is position captured at index ?

Hi tuxcnc,

Have a bit more of a look at the module code.

1. Index count is captured in an ISR.
2. When the next servo period runs the module, the index input is set in the data packet so LinuxCNC knows that the index was detected.
3. The index count captured in the ISR is stored in the data packet.

On the LinuxCNC side, if the index enable hal pin is set and the phase Z input (the index input) then the the index count is set with the encoder count, the count that was captured in the ISR.

The ISR latency is the only potential timing miss match.

Using Mesa 7i95T for laser + galvo (xy2-100) control

Category: Driver Boards

The differential input is because the full XY2-100 interface has a status channel
but its not required for operation.

Ok, in that case the status channel can be skipped as the galvo does not seem to implement it.
So the options are using two step/dir channels, or one step/dir and two sserial  for their tx channels? There's no way to avoid stealing step/dir channels if using the galvo on the 7i95T?
Although, in the end, the 7i78 might be needed anyway.

The serial TXEna pins would end up as GPIO pins and have to be set into the enabled
state in the hal file. 

What does this entail?

Do I need a better PC?

Category: EtherCAT

I don't think its a servo hardware issue. All of them sound like gravel sometimes. Or they are all smooth. I'm wondering if its something to do with the feedback loop between the servo and linuxcnc? It sounds like they are being commanded unsteady changing speeds at a somewhat high frequency. They only have UVW coming out of the motor. And encoder seems to have standard a/b v+ v- stuff going on. I don't think there's any hall sensor for the rotor.

Short in the wiring, missing ground or something similar is possible.
Plasma systems are pretty unforgiving due to the massive EMI they
generate at arc start.

The card is likely repairable by replacing U5 and/or U7

Even shielded cables can be a liability if there is a ground error
as they can couple ground noise into the signals.

Thanks Andy,
Since writing that I did manage to inadvertently introduce an axis offset via the tool table, so have become super cautious.

You would load the 7I76eu firmware that includes PKTUart support

7i76eu_7i76x1_pktv3d.bin

This file is in the 7i76eu.zip archive downloaded from Mesa's store (in the specifications tab)

You program it with mesaflash, something like:

mesaflash --device 7i76eu --addr 10.10.10.10 --write 7i76eu_7i76x1_pktv3d.bin --reload

Menos de 1v antes de encender linuxcnc y 0v cuando lo enciendo en step/dir
pero tengo tierra, cables blindados y filtro emi que pudo fallar?

By experimentation, the Y and X offsets can be entered pressing tool touch off with the wrong axis selected. On a 3 axis mill, as far as I can tell numbers in these columns are ignored.

They are not ignored, but if you have X and/or Y offsets applied when you touch-off then the tool offset anf G54 offsets will cancel out. 

XY offsets are not often used on a mill, but some machines have one head and a number of tools that pop down from it, and XY offsets are useful there to account for the different positions of the tool axes. 

I suggest making sure that all the offsets are zero in the tool-table editor. 

If you do find that you have accidentally put an offset in the wrong axis, then you can MDI 
G10 L1 Pn X0 Y0 G43
linuxcnc.org/docs/devel/html/gcode/g-code.html#gcode:g10-l1
Where "n" is the current tool number.

thanks a lot Tommy,
i’m trying to control two servo drives (Modbus RTU) with a Mesa 7i76EU in LinuxCNC, but I can’t use Classic Ladder or PktUART

Have you spotted the new Modbus / PktUART driver? It's more flexible that mesa_modbus. (but only exists in the dev version of LinuxCNC)
