Hi All I hope someone out there can help me please. I am building a laser cutter/engraver based on the Bdring model with maker slides and v slot rollers. I have had this working with New DSP CO2 Laser Cutter Engraver Machine LCD Motion Controller System PH3 New DSP CO2 Laser Cutter Engraver Machine LCD Motion Controller System PH3 | eBay I am trying to set up this board but I am not having much luck. If I switch on the machine the x and the y axis go to the home postion fine. but if I try to move the zxis with the arrow buttons on the machine or the software I somtimes get a jerk then nothing.or I get no movement at all. I am trying to setup the parameters but with no luck I came across this page dsp:dsp_controller [Buildlog.net Wiki] but the file that is mentioned there will not load into the progamme. Can anyone help please. Bob
