Tommy. You honestly need to lookup RMT based controls if that 32bits is your hardware (suggest the P4 if they are available to you). If you're after half-decent motion control performance and reliability, that's the only way to do it really (imho). Yeah man, from scratch!!

github.com/espressif/esp-idf/tree/master...ls/rmt/stepper_motor

That, and grab a good doze of knowledge of mutual exclusion runtime(mutex, semaphores, give, take, locks, ect), and the end result should match up to as close as it gets to a parallel compute (aka fpga).

to save 30 seconds out of your life try

sudo shutdown now

You might need to give permissions to skip the sudo password

I wonder if Wez is OK...

Totally cool project yeah, I remember looking into it during its infancy but wasn't geared up to import and compile any of it I think Wez attempted a proof of concept here, which he materialized already, however I sense he lacked the courage or perhaps the time to complete it. I looked at it again a few hours ago and it seems to be only missing the timing critical & comm integrity on the blocking/non-blocking/locking threads and other runtimes. Haha maybe you can finish it up (hardest part though, need a sharp oscope and a vivid logic analyser, beware!!).

I'm sure he's fine. Obviously busy with worlds' more important stuff, we all are!

 

if you look carefully at the pics on page 3 you should be able to figure out the wiring.
One pic shows the ribbon with two groups of wires.
one starts with a black wire and ends with a gray wire.
one starts with a brown wire and ends with a brown wire.

black to gray is for megas's pins 23 to 47
brown to brown is for pins 2-12

The IPTM-60 is non-HF which implies blowback type.
The naked tip does not lend itself to ohmic sensing because the tip is shorted to the work lead clamp until it blows back, You can test this with a multimeter on tip to ground clamp. The solution is to use an external probe probably lowered with an air ram. QT plasmac supports offset probing for  this but more inventive folks lower a circular probe that encircles the probe tip.

Only other thing I can think of is to add 'G0' to those 'G53' lines.

Hey PCW,

I can give it a shot at least. Since it'll show up as a 5i25 after flashing I think it should work with the correct bit file.

Thank you!

Looks like your config is looking for a directory that is no longer there:

 
[edit]

I'm not aware of a file 'null.ngc' in a regular installation so maybe that is something you have customized in the previous version.

edit: problem solved
outpins works like a switch, but had my probe connected with the wrong polarity ..

It is T bot. But kinematic is same for all of them afaik. Driving in same direction - moving along motor axis, driving motor opposite - perpendicular axis is beeing moved.
