I watched your series as I awaited the arrival of my machine. Very good it was too.
I don’t believe I wiped the pre-loaded software off the chip as you did by accident, but just in case, what symptoms did it cause? Did Easel still work the machine with it gone? Easel works perfectly on mine, I just can’t get anything else to talk to it !
Try to use something like HyperTerminal or Putty to talk to your Arduino through the serial port. It doesn’t get much simpler than that. If Easel can talk to it and a terminal program can talk to it then it has to be a problem with the configuration/setup of your machine/software with respect to the g-code senders.
Here is mine GRBL setting, just put $$ on UGS command line to see if you’re able to communicate GRBL and if it is matching. If you see screen similar to this and numbers are all different, we can straight it up.
Having disconnected Hyperterminal, I started UGCS and it worked! BUT
First off all the settings returned by $$ match yours - that’s a relief thanks.
So, I tried jogging it - fine,
So, I loaded a v.simple file (to excavate a small rectangle) and sent it - Now the spindle goes racing way off and clatters against the right hand rail. So I’m thinking, wrong units?
Anyway, I close UGCS and open JSON & ChiliPepr - It connects! Jog? well at about one command every two or three seconds!
I feel I’ve made some progress but now I’ve stumbled into more problems.
Yes, Virginia there is a Santa Claus,… er,um, You can run 3d files in UGS it works awesome for that since when changing bits it’s really easy to reset your z zero. especially if you are using a touch plate.
