Okay. I am looking for known good values for Clearpath SDSK servos on an Avid router, specifically a Benchtop Pro. There is no way that I am the first person to set up this specific configuration.

Its rare to find people with identical setups. Start at about 750-1500 and see how you go once you are moving. The mass you have to move will affect the maximum value. Assume for now 3000 will be absolute maximum. Remember its a trapezoidal accelleration profile which means the deceleration is also affected by this setting. I have had to reduce accelleration to prevent the motor decelleration being overrun by the inertia of a moving mass which caused following errors.

Its better to get reliable motion instead of shooting for the stars immediately and failing.

Its likely you have only 1 encoder enabled in your hal file.

To check the pinout (and number of encoders):

mesaflash --device 7i96s --addr 10.10.10.10 --readhmid

The 200XT may be a HF start device. hyperthem machines that size are. This might mean you need to connect the thcad upstream of the HF generator. If not, It's likely to have damaged the THCAD or the 7l96 encoder. Tommy is the expert in this area.

But as PCW says, seeing 0 volt and 45 volts indicates it is working.

Rather than look at the reported voltage, check the encoder velocity pin in halshow. When not cutting, it should hover at or near the 0 volt frequency. Also it should be bouncing around. If it isn't and just a fixed value either there is an error on your encoder config in HAL or there is an issue on the high voltage side.

Using the plasma bit file, you have 3 encoders so damaging one encoder might have an easy  work around.

Looks like halcmd was run without running LinuxCNC

mesaflash --device 7I96s --addr 10.10.10.10 --write 7i96s_p1encd.bin

should work

mesaflash --device 7I96s --addr 10.10.10.10 --write 7i96s_p1encd.bin --reload

is probably better

 

Seemed to upgrade, but I don't see additional encoders.
Before I did the upgrade (Linux running) I captured all the hm2 stuff see: hm2names.txt
Then LinuxCNC closed,  I did the upgrade and followed up with reload, that seemed to work see upgradetxt.txt
Then captured hm2 names again see:  up_hm2names.txt
No apparent changes, and when I look in HalShow I only see encoder0, I was expecting to see a few more.

Not sure what I did wrong, unless I was supposed to do the write and reload in one pass instead of two?
     

OK, went through those, and i have to agree with PCW on number 2 here

It is pretty much useless as it does a lot of things but the thing it should do, it does not, namely amplifier fault!
I would not use it.
