I saw your question first here

Sorry, that interface was down for a couple days.

Retry
Head over here:

and briefly describe the problem

It gets all the info to the right place.

Mock
Please try the interface again at

https://www.synthetos.com/contact-us/

That will properly transfer your contact information.

Riley reworked that interface e, it should be working again.

I don’t have a working setup to experiment with, so am just reading and trying to understand what you are doing

Sidebar comment – Chillipeppr seldom starts from ‘scratch’. You may want to flush browser cache as well, but not at all obvious that has anything to do with your issue.

If your first step is to home the machine, setting Z=0 at the top limit of Z travel, why do you say jog the machine z+ 1.9 to get closer to the touch plate? seems z-1.9 would move down closer to the touchplate. If in fact z+1.9 moves down, I have to wonder if your polarity is reversed.

Also, your Gcode snippet G28.3 Z6.5 yet you say “and it will stop and set the z to 8.5mm (as it should)”. Doesn’t the command say set it to 6.5mm?
I assume 8.5(or 6.5) is the thickness of your touch plate?

Your Parameter file looks mostly OK. Your jerk homing settings are very low (typically 2 x the jerk maximum settings. e.g. $xjh=10000)

Also,, at the point you created the $$ file All Limit switches were disabled and Soft limits disabled. Not clear where in the timeline that occurred.

Any of these observations make sense?

o I have a few questions:
* Is there a way to have a id tagged into each {gc:””} message I send that gets returned to me when that move is complete. That way i can maintain my own checkpoint queue and resend the aborted lines of G-Code as needed.
* Is there a way to get the TinyG to dump the planner buffer so it can be reloaded?

What you describe doing in these questions sounds very similar to what Chilipeppr does. I’s all open Source code, have a look.

I believe the answer to your first question is no, because CP creates such a tagging wrapper to do it’s job. TinyG does not do it.

This wiki item

https://github.com/synthetos/TinyG/wiki/ChiliPeppr-PCB-Auto-Level

is a comprehensive tutorial on how probing assists in leveling a PCB.

Probe wiring: connect wire from tinyGV8 Xmin switch port to tool bit with clip lead or similar.
Connect ground to surface to be probed.
Shielded pair recommended.
Ground shield drain wire to GND at tinyG as well.
