When you say "thanks to HII Newport News Shipbuilding", what do you mean?

Edit seems to brake the original post, ini was missing

Hello everyone,I've recently converted a second hand CNC router from Mach3 with ESS to LinuxCNC with a Mesa 7i96s board. I've used PNCconf to generate my initial configuration, but I'd appreciate if someone could review my settings and let me know if everything looks okay.Machine Specs:

• X460, Y750mm, Z300   
• 20mm linear rails
• 10mm pitch ballscrews, 20mm diameter
• Construction: aluminum profiles bolted to 12mm steel plates, welded gantry sides
• Motors: Y-axis 6.8Nm stepper, Z + X-axis 3Nm stepper
• Drives: DM556 V1 48v
• Spindle: 24K RPM 2.2kW ER20
• inductive endstops 
• good latency values mostly sub 3000ns servo

PNCconf Settings:

• Step On-Time: 5000 nanoseconds
• Maximum Velocity: 3000 mm/min
• Maximum Acceleration: 400 mm/sec²

Key Config Values from INI File:

• X travel: -2.0mm to 460.0mm (STEP_SCALE = -200.0)
• Y travel: -2.0mm to 750.0mm (STEP_SCALE = 200.0)
• Z travel: -300.0mm to 0.01mm (STEP_SCALE = -400.0)
• Step timing: DIRSETUP/DIRHOLD = 10000ns, STEPLEN/STEPSPACE = 5000ns

Questions:

1. I see a

   z-neg-limit

   signal in my HAL file that doesn't seem to be connected to anything - is this a problem?
2. Are my velocity and acceleration values reasonable for this type of machine?
3. Any other issues or recommendations before I start cutting?

changes/upgrades
As I am already in the process of messing with the machine, would you recommend any meaningful upgrades or changes to it? I will mostly mill soft materials like wood but also want to try aluminium. 

1. should I change the microstepping ( it is 10x at the moment)
2. other stepper motor or drivers?
3. switch to s curve compact fork?

I've attached HAL and INI files below for reference. Thanks in advance for any advice!

 

Hello, I've the same issue on Rpi5 but your solution do not work completely.

I've on the boot the DSI display working well but after starting, Linuxcnc switch to the HDMI and I do not find anything in the configuration to display on the DSI and on the HDMI.

Do I've miss something ?

Usable hal pins
amplifier-enable
machine-is-on
e-stop-out
x-enable
something like this
x-enable hm2_7i76e.0.7i76.0.0.output-00
Replace board and pins accordingly.

Today i took some pictures of the machine . This is a small machine with a footprint of 120cm x140cm x 170cm but weighs a whooping 4000Kg. Its made from epoxy granit of some sort. The last picture is how the machine used to look ,it´s the only picture i found online.

No worries mate, you not is Sydney are you ?
There's a couple of us here.

The project has been on a bit of a back burner for a while. Our current prototype cantilevered gantry wobbles enough that we need to get that sorted before doing more investigation on cut "feeds and speeds", etc. Everything is basically usable though.

We would like our LinuxCNC system to control an activity light. This would be a red light on the machine active when the motors are engaged. Does LinuxCNC already have a feature to control such a thing? Where should I look to find the interface?
We are using a Mesa board and a Raspberry Pi. Can I route a control signal through to an output pin on the Mesa board?

Thank you.

What does the motor say on it?

Remember: the motor sticker/plate specifies the average (RMS) current.

The driver current will be listed as peak current (about 1.4x the average).

Therefore, a 4.6A stepper motor needs a 6.5A driver, for example.

I have measured at end of the cable previously and got no output there either. However I will try again at the port. I have confirmed by swapping the BOB is good. But I will test at the port.

Thanks.

I have never purchased either of these, but it might work well for you: www.aliexpress.com/item/1005005972825346.html

Will do. Wont be able to get them for a while now as it i just after midnight here. Expect them before this time tomorrow.

I get it. (regarding the txt files)

I have the machine temp hooked up via ethernet so perhaps I can direct post them to the forum.

'Command' needs an actual application (ie linuxcnc) not just a path to an ini file:

try:
Also you might want to change the 'Trigger' to 'on login'

Where does the 48VDC come from?

If there is a transformer leading to a rectifier bridge, just connect the transformer directly to the new drives (connect each drive separately through a terminal block or something, do not "daisy chain" drivers).
