hi to all, i have made my own touch plate with small croc clip on the spindle as negative and the plate running off pin A5 on my arduino and i am using grbl control software. when i run the z-probe command it does what it should and settles nicely but when i hit the send button to start engraving or carving its nowhere near the material and about 10mm away from it. my touch plate thickness is 2.00mm and i have made a separate g code file and if some one could check it for me as i am certain i have not done this right.

g code i created is

G21
G38.2 Z-30 F100
G92 Z -2.0
G91
G0 Z 10
M30

Chinese pulse engine or interface?
Many of them do not support probing. The pulse engine stops Z travel OK, but does not report the XYZ values to the PC.

thanks roger for your reply, but I have no idea what you mean by pulse engine or interface. all I know is the control board has an Arduino nano on a shield board with the word developower v2.0 stamped on the shield board. ill see if I can upload some pics of it tomorrow.

edit: roger if you have a look at this post I put on the other day the pictures of my control board are there.

regards

Dean

Well, do you have ANY specifications for what it can do? I ask because I know some of these implementations are NOT complete: they do not handle all the g-code instructions. They are very much a work-in-progress.
(And probing has always been a very difficult case to handle.)

I will see what information I can find for you roger and I appreciate your help on this.
