Ok, Its already been set to metric so that wasn't it...  I'll read through the manuals and see what the settings should be. In the meantime, I'm confused about something. I loaded mach yesterday. I loaded in gcode. The simulator showed on the screen. I loaded it again today. The same gcode, the simulator now does not show on the screen?

ok ive enabled all of that... the e stop gets seen on 11.  and i assume 13 through to 10 are ok. So I have manually moved the machine into a certain position and set to xyze = 0000 however when it runs the gcode... it says Z74 so naturally it moved z up... and it crashes into the top... what it reads though is 3mm when it hits the top so how do I match dimensions in teh software to teh actual dimensions physically?

Thanks

actually pin 2 = x = green when in position
pin 4 = y = red when in position
pin 10 = z = red when in position
pin 15 = E = red when in position

Is there any way to step through gcode lines to debug...

ok its seeing all the switches for sure.... red when triggered... green else

pin 2 = x
pin 4 = y
pin 15 = a /E
pin 10 = e stop = z (this doesnt seem right...)

well its not a big problem with remapping... I guess its just being able to port gcode from winpc nc and getting it to run properly and that's pretty much dependent on reference... where xyz =000 etc

Hi...

Ive gooten mach 4 as a replacement to the clunky but working winpc nc... however I'm finding it quite difficult to get mach 4 operational. These are the problems I am having. So far I have a high z machine and I can control the motors fine so i have comms etc

1. The first problem is homing the device. In winpc nc it would go to xyz 000, but i have no idea how to do this with mach 4 it just keeps crashing into the sides. How do i fix this?
2. The tool path... when I loaded the software initiallY i could see the complete toolpath and build on screen now I only see part of it... just a red line at a right angle. i have no idea how to restore it. Is there a factory reset?
3. Winpc nc was pretty buggy so We had to write a converter to change x + to x- and y+ to y - in some cases. So now the axis are the wrong way around again. rather than having to rewrite the converter is there any simple way to switch the polarity of the axis?
4. How do I change A to E axis? again i can rewrite the compiler but I'd rather change the settings in mach 4.

thanks! I have more questions but they are my main problems right now...

Thanks I'll add some new posts/ I was using winpc nc before this and the axis orientation ie + or - are different to what is in mach 4. So apart from having to write a converter to change + and - values is there any way i can change the orientation of the xyz axis?

Also the tool paths have partially dissaperaed off the screen. I can only see part of what the machine was printign before not the whole thing. I have no idea how to get it back.
