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

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.

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?
