Tormach / Mach3 / Sprutcam code failure
« on: July 31, 2008, 12:30:56 PM »
I've just attempted to run my first personally generated G-code program using Solidworks to Sprutcam for a Tormach PCNC110.

When I run the code it starts off OK, i.e. moves to a tool change position, requests tool change then moves Z towards the workpiece. However the spindle does not get turned on and an error box pops up saying

Error on line:2 - Unspecified error

Meanwhile the G-code program continues running, generating machine motion ( but no spindle rotation)

Clicking OK to the first error message brings up another window - M5 - Mach3 VB Script Editor with the code DoSpinStop()

Funny thing is there isn't an M5 command issued from my code. ( Is the M5 part of the M998 instruction ? )

Any ideas why this is happening ?

[Program sample below]

Have you checked that the spindle control switch is in the "auto" position and that the head/door interlock switch is closed?

I don't know if M5 is part of M998 or not but my SprutCAM-generated code for a PCNC 1100 matches your lines N10 and N20.

The spindle is in the auto position, and I can start it with either the spindle start button on the screen, or using an M3 command in the MSI.
M5 also works in the MDI to stop the spindle.

please attach the M998 macro.

I should also say that I set the units to metric in the M990 file as previously discussed, and also that the M998 worked when using the firstpart.nc program.

   x = GetUserDRO( 1200 )   
   y = GetUserDRO( 1201 )   
   z = GetUserDRO( 1202 )   
   PosIsMetric = GetUserDRO (1209)  ' this is definition of what units the tool change position is in
   CurrMetric = GetLed (2)   
   If (CurrMetric <> 0 And PosIsMetric <> 0) Or (CurrMetric = 0 And PosIsMetric = 0) Then ' we need no conversion   
       DestX = x   
       DestY = y

Dont see anything in that macro that should cause a problem also dont think having the Speed and M3 on the same line as other code should cause a problem but just try placing the S1600 M3 on the line above so it looks like this

S1600 M3
N40 G0 X160.315 Y32.987 Z25.

I will see if I can grab the Tormach install and see what happens here but your code certainly seems to run fine on standard Mach3.

One of the things I notice is that some of the G codes have the leading zeroes missing. ,e.g rather than G00 this code has G0.
I don't think that this should be important, but I'll probably modify the code tomorrow when I'm next at the machine to see if it makes a difference.

no, Mach can recognise G0 or G00, G1 or G01, so thats not a problem.
Been looking at the Tormach site to see if I can download the xml and macros but cant find them I am afraid.

I've just checked out the M6 macro as well. I have two, M6start.m1s and M6end.m1s

M1Start has the code:

  tool = GetSelectedTool()

  SetCurrentTool( tool )

but M6end is blank.

Does this make sense ?

Probably ok as your other macros will be doing the  toolchange.
