JMC Servo in PP mode

Category: EtherCAT

Hello PedPEx,

I'm currently setting up my own EtherCAT based controller as a mock up before I replace my current control board. Your single axis configuration really did help getting my JMC iHSV57-30-18-36-EC moving.

One question though: You are setting "setp cia402.0.pos-scale 3600". Do you have any reference where this value comes from? Can you give me a hint how it gets calculated?
My final setup has ball screws with 5mm/rev thread pitch.

Second question: Did you ever try to use the "basic_cia402" device type in the EtherCAT XML file and got it working?

Thanks,

Uwe

Hmm. It appears it won't allow me to do that. LinuxCNC terminated with an error.

MESA 7i93 PWM question - motor rotation direction switch was created by pingtomi

MESA 7i93 PWM question - motor rotation direction switch

Category: Advanced Configuration

Dear All,

I try to set up 7i93 PWM control for my ATC motor and I struggle with its rotation direction change, meaning:

- if pwmgen.0.value = positive number, pwm signal is on PIN6 as expected, motor rotates clockwise.
- if pwmgen.0.value = negative number, there is no PWM signal on PIN8, motor does not rotate at all.

I use PWM controlled mosfet bridge which expects CW and CCW input PWM signals on TTL level.
Regardless of pwmgen.output-type it does not work, but based on hostmot2 manual in my understanding it should work with output-type 2.
7i93's firmware is standard.

What do I wrong, or how can I change the rotation direction with PWM if my motor drive expects CW and CCW PWM signals?

thank you for your help.
Regards,
Tamas

Interface to LightBurn (is pylib a better choice).

Category: General LinuxCNC Questions

My router(laser) is currently torn apart undergoing an epoxy leveling upgrade to be followed with motor belt gearing change for plasma cutting. So weeks or end of summer away from any laser work.

I think linuxcncrc should be treated as a dead end as python has more support.  

What would be nice is a linuxcnc python TCP server that can communicate with Lightburn for laser cutting operations.
  • TCP because that's supported by LightBurn running on a Windows PC to LCNC.
  • Python as that seems best supported for LCNC interfaces.
  • Lightburn interface as it works very well for laser operations. (outline cuts, laser offset, home, zero, etc.)

Getting Gcode across was easy using linuxcncrc and some string substitutions.
What takes a little more work is the extra commands to home and things like getting position. The Lightburn GUI has a serial terminal where you can see some of the extra commands. They use a lot of 3d printer Gcode extensions (M114 to get position).

What is your interest/focus?

if you are not on the latest release of probe basic, the offsets column setup is in the custom_config.yml file, change the columns to display to XYZR then save the file and restart probe basic and retry.
 

Yeehaaa, it was the custom_config.yml

Great,Großartig ,Thank You,Dankeschön !!!

need to update your config with all parameters to set the correct columns, it is calling for a axis to be set but you have no a axis configured.

kcjengr.github.io/probe_basic/machine_config.html

please ensure your config settings are correctly set for 3 axis XYZ and offset table is correctly set for XYZR and report back if that resolves!

I think just switching the drives between the two axis would be one thing. Relatively easy done in the config, or perhaps moving ethernet cables between the drives.
Then one can think of hunting done the reason for joint n amplifier fault. It happens because joint.n.amp_fault bit get set by the drive.
Check how that is connected in the hal file.
Look at the drives' outputs in halshow, compare between good and bad drive. Under lcec component.
Also temporarily increase FERROR and MIN_FERROR, set them really high while testing. Don't forget to lower them when done.
Search the forum, rodw had an amplifier fault and needed to perform a factory reset on an ethercat stepper drive.

The 200 RPM is probably a GUI setup ini parameter

Can you set say 12000 RPM with (MDI)
 M3 S12000

?

Hi all, Im starting to transition from mach3 to linuxcnc on my hobby machine. Im having troubles at seting up the PWM to VFD corectly. 
I added the folowing to the custom.hal

# --- Load the PWM generator component ---
loadrt pwmgen output_type=1

# --- Add the PWM generator functions to the servo-thread for smooth updates ---
addf pwmgen.update servo-thread
addf pwmgen.make-pulses base-thread

# --- Spindle ON/OFF control (Relay on Pin 17 thats on my breakoutboard and works nicely) ---
# Connect the signal from the 'spindle.0' component to the physical pin.
net spindle-enable <= spindle.0.on
net spindle-enable => parport.0.pin-17-out

# --- Spindle Speed PWM signal (Speed on Pin 1) ---
net spindle-speed-cmd spindle.0.speed-out => pwmgen.0.value

# Enable the PWM generator ONLY when the spindle is supposed to be on (M3)
net spindle-enable => pwmgen.0.enable

# Connect the pwmgen output to the physical parallel port pin 1 - this sends the 0-10v pwm from breakoutboard to vfd, also needed inverting
net spindle-pwm-signal pwmgen.0.pwm => parport.0.pin-01-out
setp parport.0.pin-01-out-invert 1

# Tell the PWM generator that the max value (100% duty) equals the scale from the INI file
setp pwmgen.0.scale 24000

My problem now is, in linuxcnc the maximum rpm it lets me at 100% is 200.
but it doesnt even reac that..my pwmgen.0.value is 200 in halshow. (added a picture).
output pin is corect, i get 10V if i dont invert the pin and vely low V when i do invert it.

i am confused as to how or why max i get is 200? same with speed-out wich is the one setting the .value
What am i doing wrong?

A bit of a long shot, delete the .var and .var.bak files in your config and try again.

[edit]
Actually I'm not sure if ProbeBasic uses .var files at all.
