PCB Autolevelling for Isolation Routing - Shapeoko

NOTE: this program is outdated and won't work properly with grbl 0.9i.

Very nice step by step tutorial and very nice program for height adjustment. Wirklich gut.

great video -- what knife are you using?

Thanks. This is really excellent info!!!

very nice i would like to do my own pcb's one day
because this protoboard is not for me to many jumper wires

This is Awesome!!!  I recently purchased a "T8 CNC". I am guessing I need to change or update the firmware on my Arduino.  Could you do a video on that too?

I'm trying to use your program and everything seems to work the same except after hiting save the cnc does nothing. I use fritzing for pcb designe, flatcam to create g-code, and drag and drop into your program.it creates a box that matches my pcb so I figured I have done everything right so far. when I open the com port I hear the program take control of the cnc, but after the next few steps, unlocking etc, and finaly hiting" save" the cnc does not move. any advise? thanks

Hi Martin. First of all, thank you for your excellent job ! your tutorial helped me a lot ! I tried to do what you described in the video but unfortunately i have a problem. When i use PCB-gcode in Eagle, i only get two files, one for for the drilling and the other one with for the etching and i never get other files for the border. When i use the HeightProbe2 program, i drag and drop these two files and then the x and y dimensions become some strange values (-317826, 127000) while my pcb is about 30mmx30mm. Of course when i try to operate the program like this it gives me an error. When i manually change the dimensions so i have a reasonable numbers of points to probe, i open the COM port normally and release the safety and press start but the program hangs and i have no response from the machine. Can you help me with that? 
Thank you in advance,

Hello, nice work, how do you choice the option to cut the pcb in 2+ times? i cant find where it is, , ty good day.

It is good practice to drill first so as to not spin off the donut/pad.

why the need to probe the full surface, when the cut depth should negate any surfacr irregularities, which for a copper clad board would be irrelevant, one probe for tool zero deck height should be enough, probing like that is used more for curved surfaces to be milled, to keep the mill cut uniform throughout the cut .

Im not be-moaning your set up, it's just a long process for which really only needs one probe, then set the withdraw height to clear the copper for the tool to move to the next cut if need be.
I've seen a mouse carved, the probe was spring loaded on a micro switch element set to a couple of thou' contact distance to keep probing accurate.
It's your time, but that probe method is way too long dude.
good vid and nice work.
