Hi I have a CNC xPro V2 board, that looks to be wired up properly and jogs the machine in all the right directions (when connected through Universal GCode Sender), however, I am trying to change some of the settings - specifically, the S100, S101 and S102 (X, Y and Z steps/mm). Basically, the axes move about 5mm for every 1mm I tell it to go - default settings ar at 200 and they need to be about 26. I've never done this before, so was assuming that a command typed into the Command Line in UGS would do the trick ($S100=26), but all I get is Bad Number Format. I've also tried about four different interface programs to read / set these parameters, but to no avail. These settings appear to be read-only. Is there something I am missing? Or do I have a 'bad' board? The GRBL version on the board is 0.9i. Don't know if that's relevant or not, but just thought I'd mention. Been at this for 2 days and on the verge of binning the board and starting again with something else. ANY help would be appreciated. Thanks for all the help so far, folks. Mikey
Ahh the old 'bad number format' rises again. What you should be doing is Shift + 4 that'll get you your 'dollar' sign, then the parameter you want to change then equals, then whatever you want the new parameter to be, as follows. $100=26.667 Then enter, you should get an okay in the console window. You've get an extra S in the mix here ($S100=26) leave out the brackets though. Rich
