So, armed with a working spindle encoder, I've tried my luck with a rigid tapping cycle.
Spindle runs, and the code gets to the G33 line, but after the spindle advances down a little, motion and the spindle stop without any error message.
Looking here  Docs/Examples/Spindle  section 6.1 I am assuming that I don't have to add yet another encoder to the hal, but can use this working one?
I did test the spindle running at around 500rpm, and simply changing direction, and the system manually happily does that.
So, not sure where to look.
Thanks

I am trying to upgrade linuxcnc to 2.9.3 I was running 2.7.x I am using all the same hardware but when the parallel port tries to load it gets the I/O ports at e000 [disabled] =8error. On the old version is was running a port 0xe000 and irq 3

Is this the same computer that was used before?  How about the parallel port card?
The [disabled] indication means that the port will not work, the kernel has done something to disable access to it.
I had this issue with a specific Dell desktop machine, and had to use a different PCIe parport card.  I recommend cards with the NetMos 9900 or 9901 chip for use on PCIe slots.  These have always worked well for me.

That file is the Linuxcnc driver, if that is missing there is something wrong with installation.

Ahhh thanks, that extra joints is what I need for sure.

Hoping I can make a custom M code to control them

Also looks like the number of joints can be increased if recompiled. Per the docs.

The limits for the following items are compile-time settings:
num_joints: Maximum number of joints is set by EMCMOT_MAX_JOINTS.

Will give this a shot, thanks

Invert the enable pin in StepConf.
You can edit the existing config, click on the right side where you have chosen that pin.

Sorry, failed to sort out the links carrying on into the text.

Gates Belt Tension Calculator
Gates 'phone Frequency App

So from the type of belt, length, number of teeth on the pulley, motor speed and power etc, Gates recommend tensioning to a twang frequency between 39-41Hz.
At this tension, the thing sings pretty loud with the covers off, but is far less sensitive to oscillations. Have P of 0.45, and I increased to 0.015 
With output scale at 4500.

Have also now looked at the motor speed with zero volts to the VFD and its 250 (Hurco book says 150, but for now its in the ball park).
The rest of the low end volts looks like this.


 

Hallo, ich habe Die gleiche Maschine wie Du gekauft. wie weit bist Du mit Deinem Umbau? Welche Servos hast Du schlussendlich verbaut? Woher kommst Du?

Hello,
 have a problem with my LinuxCNC. I run the "LinuxCNC Stepper" I complete my setup and I test each axis separately, it works very well, Once I finish the configuration and I run the shortcut created on the desktop, I can no longer control my axes. When I launch the shortened engine is released, as if I hit the power

Someone has already experienced this problem?

2.6.32-122-rtai

Thank you very much, Hakan!

I'll read the linked document, but your Explanation was perfectly understandable for a starter!

Cheers,
Matthias

dcConf is a setting some drives, typically servo and stepper motor drives, needs to synchronize the motion between them.
The choices are no synchronization (free run - often not accepted by drives), synchronization by precise time (DC - Distributed clocks) or synchronization by event (SM-synchronization).
What the drive accepts are in the ESI file for the drive and is set by a number in the assignActivate field. Check here for a lot of useful info on EtherCAT and a box for Synchronization www.ethercat.org/download/documents/Ethe..._Protocol_Poster.pdf
The sync0Cycle specifies the frequency of the DC clock cycle, or rather the period length. "*1" means 1 x applicationTime period, so often 1 ms. But different values can be given.
sync0Shift says exactly at which point inside this 1 ms the sync event takes place. 

watchdog is usually not needed, ethercat has a default 100 ms watchdog setting. Not sure what happens when the watchdog triggers.
It seems some drives needs this set specifically, such as the Stepperonline A6 servo drive.
The intervals are 40 nsec long, so the setting of intervals=2498 divider=1000 one can see ends up at 2498*40*1000 nsec = 99.92 msecs.

Enjoy your trip, and no, not network, the Axis GUI.

To get the emergency stop to be removed I had to reload the code in ESP32

Thank you for your replies PCW and langdons,

You were on the money PCW! I had my MIN-Ferror set way too small - this made sense in my head, but clearly didn't work. Also swapped my A,B and Z polarities at the mesa. Thank you greatly for the tip!!

I've got the test motor running now, and am able to tune it with Tommylight's guide on the bench within 0.003mm ferror. Couple of questions for the next stage though:

- I assume I would get a baseline tune on the bench for all motors. Then instal motors, run the inertia calculator in the motor software (adust these parameters where fit), then finally re-tune/adjust my position tuning with motors under real loads?

Regarding wiring - I plan to use twisted pairs on the ANOout/GND control and each encoder channel. Can I have the 3 encoder twisted pairs in one shielded cable and the analog control in a seperate one? Or can I put them all in a common shielded cable?
Or do all encoder pairs need to be in seperate shielded cables as well?

Currently I'm just using some CAT6 cable for the encoder link and some shielded twin core audio cable for the analog voltage on the bench. However, I'd like to order the right stuff for the next stage of wiring.

Many thanks,

J
