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
