Paralell port trouble

[Hood]

So address should be 378,
Have a look in Bios and see what mode it is set to, been a long time since I used a PP but think EPP is best if I recall.

You do need to check your cable. A printer cable will operate your printer but it may not have wires for every pin. You need a data cable that have all the pins wired.

I have set standard port. Tomorrow I'll try EPP mode.
Also, I have bougt parallel data cable, but for sure, I'll examine it tomorrow.
Hood, if you are online, can we chat?

I think I discovered the source of the problem. When I unplug printer cable and observe Diagnostic screen in Mach, then I see changes. So, parallel port is working good. It must be a problem with my breakboard. I'll se tomorrow,

Remove the printer driver. Deactivate the print spooler.

Hi simpson36,
Which one printer driver to remove? Windows or Mach?

[simpson36]

Windows printer drivers can take over the port and will typically poll the port either occasionally or constantly (Epson is particularly bad) to determine if the printer is still attached, needs ink, etc. If your print spooler has anything in it waiting to print, (or sometimes even if it doesn't) it will also poke its head in to see what's going on with the port.

These activities can interfere with Mach's port driver. Many people have posted here that removing a printer driver cleared up a random port problem, and it stands to reason considergin how the PC communicates internally.

Hi folks,
thanks for your efforts.
My problem was malfunction of breakboard (DIY)

Another question,
Which Parallel port mode is the best for Mach3 CNC controll?
SPP, EPP or ECP?
