Mesa smart serial or PktUART or serial over RS232 or udp for robot joints

Category: Advanced Configuration

The STMBL drives can work with Yaskawa encoders.
(But supply is an issue)

I see that you already know about their existence, but it might be worth considering using them.

Mesa smart serial or PktUART or serial over RS232 or udp for robot joints

Category: Advanced Configuration

Hi,
as I see from list there is no support for this type of encoder.
It's yaskawa absolute 12bit encoders. After power up some mS and it sends its absolute position over UART, after that if it moves it starts to send only quadrature pulses A/B like normal incremental encoder.

POSITION_FILE and index was created by mark-v-d

POSITION_FILE and index

Category: Advanced Configuration

I would like to use the POSITION_FILE in combination with the index pulse
of the encoder to home my lathe. The idea is that you know approximately
where you are when starting up, and once you pass the first index pulse
you know the exact position. Has anyone done this... and if so can you
explain how?

If a PC running Linux breaks, try putting the old hard drive in the new computer.

It actually works perfectly 99% of the time!

Why did you install 2.9?

Which version of 2.9? 2.9.4?

How does your PC control the machine?

Help with Delta E3 Ethercat drives - hal and ethercat-conf.xml

Category: EtherCAT

That sorted it. Just #'d out the two PYVCP lines. Looking back over the build thread it was using probe basic so that's probably the issue.
I now have axis running with one encoder that's reading! Fantastic. Don't have any motor control though. I can move the motor shaft and get count and motion on the simulator display but with the machine enabled I can't jog. The sim shows movement but no shaft rotation.

I'm also getting a Linuxcnc notification "LCEC: Invalid appTimePeriod of 0 for master 0 (should be 1000000)."

A quick search on the forum suggests that relates to:
[EMCMOT]
EMCMOT = motmod
COMM_TIMEOUT = 1.0
SERVO_PERIOD = 1000000
HOMEMOD=always_homed

in the ini file but it's set to 1000000 already.

watching the "DRO" the z axis zeros then moves, hits the index, zeros, and then hits the estop. I have the offset set to 0 so it should just stop correct?

in testing the "Z" axis right now I have it passing the index point, it turns off the enable signal, seems to hesitate for a split second before continuing to the estop hard limit

Is index-enable connected to both motion and the driver?

If the encoder index  (something like hm2_cardname.0.encoder.00.index-enable)
has been set but is not ever cleared when the index location has been passed,
that suggests a hardware issue with the index signal itself.

Probe Basic backplot error when loading file

Category: QtPyVCP

After an impressively quick iterative process Lcvette and TurBoss managed to fix all the errors I encountered in this thread.

I'm sure they'll announce an updated development version shortly including these fixes.

It does set the index enable currently it just sails right by it when homing

Hi 
I am planning on using the same motor and driver for my mill until I upgrade to a larger motor.  would you be able to share your . ini  .hal  and . xml file of your configuration any what mode you set on the driver if you got it running? 
Thanks will

Could official firmware for example for 6i25 or 7i92 currently accept 224bits via smart serial from slave?

Yes if the sserialb firmware is installed

XHC-WHB04B-4 error during compile

Category: Advanced Configuration

Are you compiling from source because 2.9.6 doesn't work properly with the XHCWHB component?
If so then see this thread:

forum.linuxcnc.org/21-axis/57364-axis-co...-9-6?start=10#336658

if not, then you can get a list of the missing build dependencies

cd linuxcnc-dev
./debian configure no-docs
dpkg-checkbuilddeps

The manual turret looks like a prime candidate for motorisation...

Or get an industrial robot arm to operate the manual tool changer for you. :-)
