Thanks, this is what I already expected since i could not get it working.

General Mach Discussion / Mach3 parallel port #1 port @ 0xD00 and #2 port @ 0x378 with all lines as input

« on: April 29, 2023, 05:37:22 AM »

Hello, I try to set up a system with 2 parallel ports, is it possible to configure the system to use the standard 0x378 as port#2 and a PCI card port as port#1 at his specific port address?
It seems that i can't get the 0x378 port working as port#2 with all lines configured as input.

I tested it in real life, i changed DRO817 to DRO 202 in order to have spindel speed override working but in general, exept of a minor problem, it worked immediate.The small problem was that this line: SetOEMDro(1200,GetOEMDro(817)-8000) must be changed to SetOEMDro(1200,(GetOEMDro(817)-8000)) in order t get it working. The complete working code now is:

If GetOEMDRO(202) <= 8000 Then
   SetOEMDro(1200,0)
Else
   SetOEMDro(1200,(GetOEMDro(202)-8000))
End If

Thanks for the good help. This never had came to a good end without your help.

Thanks, from here on i hope to get it working.
Now i know how to do it in global way, for me it is just how to start.

Yea, why not? Within Pokeys57CNC I can chose any DRO as input variable. In Mach3 it does not see to be a problem, at least not from my opinion. But be aware, me and sofware is not a good combination.

Where DRO817 is 8000 or less the new DRO should be 0, from 8000 and up to 24000 it must go linear to the max. If the max is 16000 I have no problem, Pokeys has a potentiometer to scale the output. So If DRO 817 is less than 8000 the output should stay at 0, from there on the new DRO should be DRO 817 - 8000.

The PWM is already working, that is not the problem, just the output of Mach3 is, now it goes from 0V at 0 rpm up to 10V at 24000 rpm, I need to have it from 8000 rpm up to 24000. So 8000 rpm equals 0V and 24000 equals 10V. And I think it will be practical to save the rcalculated DRO somewhere else, I suggested DRO 500, but any unused DRO wil be OK.

VB and the development of wizards / Mach3 macropump for spindlemotor

« on: October 08, 2020, 05:33:27 PM »

I use mach3 in combination with a Pokeys57CNC board. I want to control my spindlemotor with the PWM output of the Pokeys57CNC board.
I use a aircoled HF spidle which has a minimum speed of 8000 rpm.
I set up the VFD to start at 8000 rpm with a max. at 24000 rpm.
The VFD now want to have 0V for 8000 epm and 5V for 24000 rpm.
Mach3 with Pokeys57CNC give me 0 to 5V where 0V equals 0 rpm and 5V equals 24000 rpm.
To correct this I need to make a macropump which hold the output at 0V till 8000 rpm.
The DRO for the spindel speed is DRO 817, the corrected value can be any unused DRO, let's say DRO 500.
In my opinion the program has to copy the DRO 817 value and hold that to 0V until the speed goes over the 8000 rpm, from that moment upt to 24000 rpm 8000 has to be substracted from that value. The output then must be written into DRO 500.
Since I am absolutely not a software guy I don't know how to do this, can someone help me here?
