Nomad: "Probing Cycle Failed"

Hi folks,

I have one of the first Nomad CNC’s from the Kickstarter, and I have been using it only occasionally, and recently it started giving me ‘Probing Cycle Failed’ every time I do a homing cycle. It does the homing, and then click to measure tool, and i click that and it lowers the drill down a few inches, pauses, hangs, and then pops up ‘Probing Cycle Failed’.

I’ve tried rebooting, powercycling the nomad, etc.

Any tips for how to deal with this? It was working better a few weeks ago, though it has never been 100% free of this issue.

I am using the latest Carbide Motion.

Here is the log from Carbide 3D for the probing operating that fails:

Would it make sense for me to reflash it with the latest grbl.hex ? Or does carbide motion do that for me already? If there have been updates to grbl.hex from the earliest days, I’m sure i haven’t installed them.

Reflash is an explicit step. It’s not a bad idea to try but I suspect it’s not the root cause.

Yea, I did that and it didn’t help.

Still at a loss for why my router is useless right now.

contact support@carbide3d.com and they should be able to get you squared away.

Sounds good, thanks Will.

This can typically happen if

  • the probing distance is too long (did younset up a very short end tool.)
  • ground and probe get shorted somehow

Keep in mind the whole structure (spindle, gantry, table,etc) is connected to ground. Did you modify or rewire your machine (especially around the tool measurement probe) ? Does anything look disconnected ?

Turns out the problem was ‘the probe contact needed wd-40’. it was sticking down. :expressionless:

I’m having the same exact problems will you guys be available tomorrow morning by chance?

Yes, you can ring us and we’ll answer the call in our queue, or send us an e-mail to support@carbide3d.com
