Can anyone help me with the connection for torch on/off for this model machine? it does not have any type of connection other than torch and air. I am looking to have a relay trigger the tork from a pin on the mesa board but I can not find what pin to use

What G540 output turns on the spindle?

You would need to setup the the appropriate
GPIO bit for spindle enable to make this work

To find the 7I92T to Gecko G540 pin mappings, run:

mesaflash --device 7i92t --addr 10.10.10.10 --dbname1 g540 --readhmid

(Assuming the 7I92T IP address is 10.10.10.10)

 

Glad you got it sorted out

You need to go through the config docs and make sure you're getting the signal and if you're getting the signal and everything is set properly in hal look in the post GUI hal file at the bottom and there's a spindle connection for actual readout, make sure that connection reflects what you have and your main hal file and in the settings tab in probe basic select actual RPM

Tool table problem first
I believe linuxcnc will just not write the axes that are zero.
The comment line is probably limited to a certain length in linuxcnc - though I can't find that limit at the moment. QtDragon is less limiting on comment length.

As for the Error message.
Am I understanding right, if you cancel the G54 offsets the process works once?

do you have a good config for this set up.
i have the same setup, but could not get right config. spindle wont start

i would seriously consider your options before you buy the rack thing, and also buy more than one if you really want it that bad.

how deep are you actually going?

since its for work, i would stray away from kickstarter tier stuff. not being able to actually adjust your settings is going to be a painful experience for you, depending on the spec of your hole.

if someone wanna chime in and correct me, but i dont think a short detect is really a control loop.

To get good results with the technology requires experimenting and constant process control. (from what I could find watching youtube, and from  conversations)

 

it does, and its called fast hole, not precise hole. depends on the spec, but overburn, combined with not being able to adjust the settings, runout from the setup, excessive electrode wear
