Yes, that should work.

You can use pncconf or MesaCT to created a configuration for the 7I92.

You can use a similar daugtercard if the Benezan card is not supported. 
 

Hello,

After some research, I came to the conclusion that a 7i92t could replace a parallel port. My old computer died and I purchased a mesa card and attached it to a computer running LinuxCNC 2.9.4. I flashed the 7i92t_benezanx2d firmware following suggestions in another thread. 

I'm trying to control a very simple CNC Lathe by Taig. The signals that it requires on a parallel port are:

ESTOP - Pin 1
XDIR - Pin 2
XSTEP - Pin 3, Inverted
ZDIR - Pin 4
ZSTEP - Pin 5, Inverted
SPINDLE - Pin 16. Just ON-OFF, no speed control.

Is it possible to make this work with a 7i92t? 

I'm attaching the parport .ini and .hal that I was using.

Thank you in advance.
 

just to be clear, the stepper motors do run when using the stepconfig wizard, the question I would ask is, will the joints Y, A run in tandem from the LinuxCNC job interface? Does the application recognize the two as one joint and move them accordingly.

Yes, if  they were selected as tandem axis during configuration.

They have single turn absolute encoder.
I don't think its a motor issue because all of them do it exactly the same, or they are all fine someimes. I put together a better b450 motherboard with a ryzen 3200g. Seems better than the $0.50 HP motherboard already. I think it does have realtek chip so I have an Intel card to stick in it too.

jimmyrig, I am very new to this and do not know much about altering the g-code, sorry not sure what to do there.

The Premier Plasma table table and computer setup all worked great when it was windows. The computer died and I chose to go the linuxcnc rout with CNC wood router. I did not know this was going to be a 2+ year setup. I would have sold this thing and bought a small wood router setup with everything pre-installed ready to go.

Now

CNC Interface Board ST-V3, and 4 WANTAI DQ542MA drivers for X,Y,Z,A from wantmotor.com
Low Profile Dell G1FN2 25 pin PCie  1-port IEEE1284 Parallel PCI Express Board.
Stepper motor Model: WT57STH115420A-X1-7000 there are 4 total.

just to be clear, the stepper motors do run when using the stepconfig wizard, the question I would ask is, will the joints Y, A run in tandem from the LinuxCNC job interface? Does the application recognize the two as one joint and move them accordingly.

Forgot to also include the nc_subroutines.

In manual_change.ngc (see attached zip file) there  are the lines:

; probe tool length
M64 P  #<_ini[pins]probing> ; turn on probing led

cat gladevcp.hal:

net tool-change  motion.digital-out-00   gladevcp.change-led
net tool-changed gladevcp.changed        motion.digital-in-00
net toolno       motion.analog-out-00    gladevcp.number


net probing        motion.digital-out-01  gladevcp.probing-led
net enable         motion.digital-out-02  gladevcp.enable
# net probe-contact  gladevcp.probe-contact motion.probe-input
# net probe-contact  gladevcp.probe-contact motion.probe-input

net reftool        gladevcp.reftool       motion.digital-in-01

net reflen         motion.analog-out-01   gladevcp.reflen
net currlen        motion.analog-out-02   gladevcp.currlen

I think the signals and pins for the lines with "net probing " and "net enable" are incorrect.

What to set here?

Hi PCW,

I found a card locally that seems similar to the Sainsmart breakout you had mentioned. I'll add the link below. It says its for Mach3 and LinuxCnc, would this work with my Mesa 7i96s. Thanks so much for your help. Interface Board CNC 5 Axis
 

Yes, that looks exactly like a Sainsmart ST-V2 so 7i96s_5abobd.bin firmware
will work with that.
