Servo Driver Plasma Retrofit

Category: Plasmac

Thank you, the wiring is making much more sense and less challenging now.  

Im using linuxcnc_2.9.4-amd64.hybrid.iso that I downloaded here.  It installed qtplasmac 2.9.  Is it recommended to install 2.10?

What is the easiest way to configure a 7i97t and a couple thcad2 for plasma?  I dont see 7i97t as an option in pncconf and in mesact there isnt an option for qtplasmac.

I asked chatgpt to create a quick ini for qtplasmac and a 7i97t and it came up with this pretty quick:

Created the Boot USB STick . both machines recognize the stick on the desk top. But dont recognize it in Bios settings . All the bios settings are set to boot from the stick , but it doesnt show up in the boot drive order.

When you're in the G-code editor, it's possible to start the program execution, but if you exit the editor, the program stops .


How do you do that? Using halui?

HY_VFD RS-485 HAL config was created by scsmith1451

HY_VFD RS-485 HAL config

Category: General LinuxCNC Questions

Re-configuring my DIY Router Mill to use LinuxCNC after MACH3 began glitching on me. At this point I'm trying to get my HY_VFD to respond via RS-485.  Under Mach3 this RS-485 adapter worked great, but not getting any response now.

I found this HAL file on line for the HY-VFD RS-485 config:

# Include your custom HAL commands here
# This file will not be overwritten when you run PNCconf again
# RS-485 Spindle Control
loadusr -Wn vfd hy_vfd -n vfd -d /dev/bus/usb/004/002 -p none -r 19200
                                
net spindle-vel-cmd-rpm-abs    vfd.speed-command
net spindle-enable              vfd.spindle-on
net spindle-cw vfd.spindle-forward
net spindle-ccw vfd.spindle-reverse
net spindle-at-speed vfd.spindle-at-speed
                                
setp vfd.enable 1

having replaced the device reference with the output of lsusb for my machine.

When I issue a M3 S6000 command via MDI, nothing happens. Would someone please help me resolve this issue?

The above HAL config is in custom.hal. I'm running LCNC 2.9.4 on Debian 12.

Also, on a fairly regular basis I get the following error on startup of LCNC:

Debug file information:

I use Match 3 on another machine and it has this functionality and I thought it was something standard. :)"You mean when the machine is already homed? "
 YES .

"But the spindle should resume at the same speed. Can you give an exmple to reproduce that?"
I will make a video.

"A bit unusual use case though, but I agree that should not abort the program."
Yes, I accidentally started the program from this menu and at one point I decided to go to the main page and the machine stopped. The program should simply not be started from this menu or it should not stop. I already know and I will not start the program in the editor. But maybe I will not be the first to find this bug. :)

Category: Basic Configuration

Thank you to everyone. I've finally got the EStop to work correctly, though I don't understand why. Apparently, it works opposite of the limit switches in that there must be a high signal on the pin at startup and EStop is triggered when the switch is opened. Regardless, I can now home and run as expected.

I'm not getting anything out of pwm to analog boards. I have tried 5 different convertor boards with the same result. Before I invest in a scope or a new mesa board can anyone spot anything wrong with the config?

Thank you,

Hi Meister,

I have setup a board file and config for the Terasic DECA max10 board and connected a W5500 module but it isn't showing up with the correct ip address.

I can confirm that the board is flashing (I'm using the quarts programmer to flash) as the LEDs change when I add or remove a bitout plugin.

The SPI clock and chip select looks right and signals are showing up on my scope on both mosi and miso lines (I don't have a digital decoder so can't interrogate the codes themselves).

The w5500 is showing up as a network device with what seems to be 5 default addresses (when I use arp -a in CMD)

Any thoughts on why the W5500 isn't configuring with the 192.168.10.194 address? I can share my board and config files and the compile output if that helps.

Thankyou!

Retrofit - LinuxCNC + EtherCAT

Category: EtherCAT

I think Beckhoff and Rexroth have a distributed Ethercat drive system where the drive is built into the servo and there is only one power and data cable.  I've never used them and I'm sure they are pricey.  If you use quality cabling I don't think the length will be a problem.   You could also mount an EK1100 on the carriage and/or the far end to locally terminate signals to Ethercat vs running them individually back.

I would suggest connecting the limit switches and linear scales directly to the servo drive...I think you will get the best closed-loop performance by letting the drive handle it all.  If you are going to all this trouble I would also be sure and get absolute encoders so you don't have to deal with homing on this large a machine.
