PSU is 8.5amp at 50v a great big round one.  I have just found a piece of paper (came with the machine) written on the back in pencil are the dip switches, looks like they are all wrong paper says
123 off =1.5a with a tick next to it
sw4 = on Half current
Micro step 5678
5=off
6=off
7=on
8=off
to me it looks completely transposed could this be it....

Hi well I tried all the settings I could when I tried to auto step the machine in settings it failed twice on the x and once on the z. finally set up all working ran a test piece without the router or extraction heard the motor fail on the x at 30% through only a small stall but enough. I have been unable to find out what specs my motors are but they are mde by motionking 23hs1404 the control cards are CW 5045 are currently set to 1.5a at half current (wondering if this should be more) the motors are 100mm?! card set to 8 steps. hope this helps.

Mach 3 is set to steps per 2000 velocity 438 acceleration 187.5 I take it this is not right.

I bought it second hand guy said he never had any issues (i'm inclined to believe him) literally had 10 hours use he didnt let me have the computer but it was on Linux anyway and I'm not a fan, its a Rhonmac as far as I know its stock and thats why I believe its a setting issue. Its on a parallel port how do I check the 25hz I'm a complete noob

Hi Guys
Having some trouble with random missing steps, my machine stops code continues to run in Mach 3 then machine goes again obviously in the wrong place due to the stop. Motors sometimes stall when I jog so I'm thinking it may be set wrong somewhere, I am hoping someone is able to tell me what my settings should be.
my machine info is
1600 steps
8 micro steps
15 motor teeth
leadscrew 30
leadscrew pitch 2mm
hope this makes sense to somebody. Its on a fully licensedmach 3 copy (to me). Thanks
