I have just ordered a lead 1010 and blackbox controller. Being very new to this I was deciding between a Xcarve and Lead with the support of Facebook groups and they unanimously directed me towards the lead. I'm super excited to get it and begin however a topic that I'm having difficulty getting a definitive answer about it the addition of an e-stop/abort switch. I have heard several different things about the addition of one but dont know if its necessary or possible with the blackbox controller. I've read the the X-controller for the xcarve has both an abort and e-stop. Is this possible to add to the blackbox? Thanks in advance from a new guy.
