FAQs / Re: parallel port to serial

« on: July 09, 2019, 02:33:49 PM »

if you are on the "retrofit road" IHMO the first things are (before buying anything):

-figure out witch stepper Motors are mounted, to get a idea witch stepper Controllers will fit.
-figure out witch spindle is mounted, to get a idea witch Controller will fit.

SmoothStepper is not a bad idea, even i am not a fan of These 5v Controllers.

FAQs / Re: parallel port to serial

« on: July 09, 2019, 02:41:29 AM »

after a while of searching on the net, it Looks like the machine has a standalone Controller, and the Serial Interface is
used for file Transfer (GCode or HPGL). But found no Information about the used protocol.

if the supplier is not able to give some documentation, it will be very hard maybe impossible to figure this out.

anyway it will not be "compatible" to Mach3/4.

the only way i see is to use the existing stepper's and do a "retrofit" with new stepper Controllers and external Motion
controler. plus an other new controler for the spindle.

if your run in Plasma mode with THC on, it will allways wait until torch on Signal Shows up.

from your code:

...
Z0.6
G28 G91 Z0.
G90
...

from Mach3 GCode help:
G28 should not be used in one line with G90/G91


Switch your machine ti single BLK mode and step through code to see where exactly the move up is initiated.

General Mach Discussion / Re: Work offset not remembered

« on: July 05, 2019, 02:15:47 AM »

you can put the following code into macropump, then the Offset will be saved every 60 seconds.

just make sure OEMDRO(1300) is not used

Code: [Select]

Const LastMsDRO = 1300 'DRO for data
Dim LastMs As Long

LastMs = GetUserDRO(LastMsDRO)
If LastMs > 6000 Then
LastMs = 0
'save the actual workoffset
Open "C:\Mach3\ActOffset.txt" For Output As #1 ' Open to write file.
'get the actual offset
wo = GetOEMDro(46)+53
Write #1, wo
Close #1
End If
LastMs = LastMs + 10
'save data
SetUserDRO(LastMsDRO,LastMs)

ok with a Little trick

create a button on your Screen witch has the "Name" shutdown Mach or something like this.

this is the code for the button:

Code: [Select]

Sub Main()
'save the actual workoffset
Open "C:\Mach3\ActOffset.txt" For Output As #1 ' Open to write file.
'get the actual offset
wo = GetOEMDro(46)+53
Write #1, wo
Close #1

'shut down Mach3
SendKeys "%+{F4}"
End Sub

create a macro in C:\Mach3\macros\your Profile Name    for example M889.M1S

this would be the code for the macro:

Code: [Select]

Sub Main()
'read last workoffset
Open "C:\Mach3\ActOffset.txt" for Input As #2 ' Open to read file.
Line Input #2, FileData ' Read a line of data.
Close #2
' make sure that we only restore the WO once
If FileData <> "999" Then
Code "G"&FileData
End if

'clear the WO data
Open "C:\Mach3\ActOffset.txt" For Output As #1 ' Open to write file.
Write #1, 999
Close #1

End Sub

then add the M889 to your initialization string

now after restart and pressing the reset button the last workoffset should be restored
