You rock, thanks for the speedy reply.

TB8 PIN    SIGNAL    WIRE COLOR   VFD
1    SPINDLE-           BLUE               GND
2    SPINDLE OUT   YELLOW            A11
3    SPINDLE+         ORANGE          P12 (12V)
4    NC                     BROWN
5    SPINDLE EN-    WHITE               GND
6    SPINDLE EN+   GREEN              X1
7    SPINDLE DIR-   BLACK               GND
8    SPINDLE DIR+  RED                  X2

VFD inputs must be set for NPN mode (J1)
 

Here is the manual for my VFD:
workerbeeit.com/H100SeriesManual.pdf


Here is the wiring I have for the SPINDLE header coming off the 7c80 (I am aware that pin 4 is not connected/used, just terminated the wire so it was not hanging loose)

I am not sure how to wire the enable and direction controls to the VFD

X1-6 are multifunction pins, and can be assigned, but i'm not sure how to wire this (someone on discord mentioned wiring as "single ended"?)

It also appears that this VFD can use ModBUS, not sure if that would be a better option than analog?

The mill also has a 2-wire manual (physical) speed dial (potentiometer) that I would also like to wire up, not sure if that should be wired to the 7c80 or directly to the VFD.

Have you a HAL file example
I have had this woking using the show hal example in you video

Hi,

The planner in the video does account the abc axis into the motion using endvelocity's.

However it has no abc tooldir (tooldir blend) optimalisation feature at this moment. 


 

Ok, here's the latest update.

Text from the log file:

The images I am attaching honestly make little to no sense, rather the values in the images.

 


 
 

setp hm2_7i92.0.packet-read-timeout 30

I would set this to 80 ( 80% = 800 usec at a 1 ms servo
thread period), or just comment it out
If you are dropping many packets, that might
be an issue.

Loss of steps might be an issue also. This may be improved
by using the interpolated encoder position, as a 10 count
per turn encoder is going to give a very rough Z axis position
command, only smoothed by the acceleration limits.

The Z motion plots look linear so the main error seems to be a variable offset
at the start. Are multiple passes at the same speed perfectly aligned?
The start and end of motion use maximum acceleration so  possible
locations of lost steps.

Or maybe you have a better way to run more than 3 axis look ahead?
I think along with the s-curve another major update would be the look ahead.

Snowgoeroe,

For my clarity.
You want pathpilot planner running in lcnc?

The planner can be used in lcnc within a few hours of work.
I can do that on request.

May I formally request this, please?

The work you guys are doing does seem very nice, but I do think there is value in having >3 axis look ahead using the current TP, on the master branch of LCNC.

Hello.
I have a 3T knee mill 1000mm x axis 400mm y/z axis.
What motor reducer you suggest for a rotating axis ?
Stepper with encoder and planetary reducer is good option ?

Hi, you cannot use ST-Link utility to flash the RT1052. You will need to use pyOCD with an ST-link (probably need to flash the CMSIS-DAP firmware).

sorry it's really not clear, on the video no pyOCD and utility st LINK, I installed pyton 3.13.1 then pip 24.3.1 then pyOCD and afters

Legal obg

Your attachments did not seem to get attached...

A good tip would be to help the next guy with a hal / LinuxCNC question.
