Or just delete it I suppose. Doesn't work anyway.

Oh, please don't delete it yet, this looks like it has a lot of potential.

 Ive been trying to figure this out on my own but I am not getting any luck, after using my 3d probe to find Z0 on work piece (down.ngc) then call for T5 M6 for example (tool_change.ngc) both move with no errors but the calculation is off at the moment after T5 touches off the tool setter tip of tool is below Z0 (123 block) but if i move past the 123 block the spindle nose will Z0 off the 123 block.When i calculated the 3dprobe length I touched off spindle nose off the block then used 3d probe to touch off the block to get it length, but the spindle nose distance is moving over to the tool length (I think) dont know what else to do.


 

 

You can try using a USB WiFi dongle, but that is also "hit or miss", so it might work fine or might not work at all or might work intermittently.
I've had very good luck with USB to LAN adapters, so far out of over 10, all have worked fine for connecting to Mesa boards.
This also gives you 2 options for Mesa so you can test what works better for you.

Thanks all. Ground the PSU but this wasn't the cause

I should have known this but turns out the pi cannot use Ethernet and wifi reliably at the same time

I am pretty sure MesaCT does not overwrite them, but been quite some time since i used it.

In case you want to prevent overwriting config files that are good and done with editing, you can use the file explorer and set the permissions to read only.

Must have earth connection, on all power supplies.

In general I lack experience in this stuff, ground loops especially are confusing. I didn't want to ground the 5v negative and create some other issue. According to what I could find online, the floating 5v is fairly normal (switch mode power supply).

Yes the case etc is ground, just 5v is floating.

Thanks pcw, will ground.

If you have the mind of an engineer, why don't you test the software's functionality instead of complaining you don't like the colour?
Its very comprehensive and the probing is first class.

No, once you get a working config stop using pncconf and edit by hand.

possibly but if you follow the updated how to sticky thread (1st post) , we don't use the igh repo anymore.

Is there a way to prevent the .hal file from being overwritten? If you manually edit the .hal file, everything gets overwritten by pncconf. Is there a setting to ensure that only the parts that were actually modified get overwritten in the .hal file?
Thanks,
Hans

So, is it best to ground the 5V and 24V negatives?

... and I measure about 100VAC between 5V- and cabinet earth.Does anyone know what specifically causes CR7 to latch on like this?

The answer to your question is there in your question, 100VAC is way to much interference, so the grounding is non existent if that is happening inside a metal box.
Does the shop have proper grounding and a ground fault interrupter?
Is the machine grounded through the mains cable, properly on both sides?
Is the power supply grounded to machine/control box ground?

Just for safety, and noise I would ground the 5V common.

The Init LED can illuminate for power related issues (check the 5V at the 7I97T)
With power related issues, the Init LED typically blinks.

The other cause of the Init LED being illuminated is because the watchdog
has bitten. This usually indicates either a latency issue with  the host, some
general communication fault or the watchdog timeout set too low in the hal file.

I am configuring my CNC with a 7i97t, but I don't have that problem. I have a Mean Well 5V 10A power supply with a ground connection for the Mesa and the Raspberry Pi 5; the Mesa needs to be grounded near the RJ45 jack, where it is marked "frame ground."
