To add probing any arbitrary point, I use the following for "case 30" (the bulk of the changes other than a closing brace are at the top) in commands.cpp:Those are the only changes I need to make before I upload my firmware and start calibrating / printing.Code: Select all

Edit: to probe an arbitrary point, then, you have to send a G30 S-1 X0 Y0.... the S-1 is what triggers my bits to run, otherwise it's just the standard seemecnc implemented bits. I did that so I didn't break any instructions they provide. Here's my 10 probe points to use with the Delta Least Squares page here: http://escher3d.com/pages/wizards/wizarddelta.php (use a printable radius of 142.68, you want the tower probe hitting nearly straight down, or it's going to be way off).
Code: Select all
G30 S-1 X0.0 Y142.68 G30 S-1 X123.56 Y71.34 G30 S-1 X123.56 Y-71.34 G30 S-1 X0.0 Y-142.68 G30 S-1 X-123.56 Y-71.34 G30 S-1 X-123.56 Y71.34 G30 S-1 X0.0 Y71.34 G30 S-1 X61.78 Y-35.67 G30 S-1 X-61.78 Y-35.67 G30 S-1 X0.0 Y0.0
May be better to take this to PM, not sure, but may help others to have it here.
Completely new to this so excuse the ignorance. I'm confused by your use of the website. From watching videos of other machine auto calibrating, I thought this would run a routine, hitting several points and store the needed settings and calibrate without further interaction.
By using the website, are you saying the probing is storing the nozzle height error for you to manually enter or you were just using it for the suggested probe points?
Thanks.
