I have read all the faq's and instructions on your forum.

things i have done:
-I have managed to get the G code set up ok.
-i've played with the rapid clearance. I have double checked the rapid height clearance with the limit switch.

I cannot get the torch to fire. The head just smashed into the material over and over. I keep reding about the DTHC online button flasing but i cannot find it anywhere in your instructions or in the Mach 3 software.

Can you please help? Right now this table is sitting idle doing nothing in myshop except taking up space.
