installed the caps on the ipac, no problems. ran the roadrunner  file  10 times with no estop tripping.

yes it is working. first i tried enabling the 2nd parallel port and put the address ecf8.then i unchecked port 1, closed , went into device manager, disabled port 1.
i then had port 2 working. closed mach3, went into device manager again, enabled port 1,started mach3, enabled port 1 and all is working.

thanks for your suggestions.switched keyboards, same problem.  i neglected to say that i have an ipac that i used to select the mpg axis. i had posted about random estop problems and was directed to some messages about ipac noise problems. i did not know that they are noise sensitive. i disabled the ipac and works flawlessly.trying to solve this problem led me to solve the 2nd parallel port issue that i had also.i will install .1 uf caps on the ipac as suggested to me .

General Mach Discussion / mpg and mach 3

i am having problems with using an mpg and mach 3. i can get it to work properly and it works well, but mach 3 will intermittently switch itself off, or switch axis on its own. for instance, i can select x axis to jog with mpg, and crank along forward and reverse but the software will switch itself out of the selected axis on its own, kind of slip into neutral until i select the axis again. i have tried different versions of mach 3 , same proplem. mpg is connected to opto isolated breakout board, pins 13,15.

fred, what brand did you buy?

have you checked out the larken viper drives? 200v 20 amp.i used the rutex drives on the bridgeport because they were unsuitable for  an earlier project. things kept blowing mosfets,even  after derating the amperage by 75% lower than the maximum specs. with the larken drives they can be user repaired as the components are socketed.
i will be using these on my next project.

hi, in the drives electronics enclosure removed fdmc, ezio , bsp,  the racking for them and the complete drive assembly.    the only thing left is the 24 volt transformer,capacitor, the 4 24vdc  relays . 1 of these relays is used for controlling dc power to the rutex servo drives.it switches on off a 3 pole contactor.my contactor is 110v coil as i had it already.  the old contactors could be used, mine were a bit buzzy for my liking.  depending on the drives you use , the existing capacitors and rectifiers could be reused. i had to change to higher capacitance.the existing fuse blocks and terminal strips are still in. i also removed the eaf board in the transformer cabinet.

General Mach Discussion / setting up second parallel port
« on: March 06, 2007, 07:59:20 AM »
i am trying to set up a second parallel port on a dell optiplex .i have installed a netmos 9805 pci  card. the drivers are installed it shows up in device manager.i am using the current release of mach 3. in the configuration screen of mach3, i have checked the box for parallel port 2. the pins are enabled for port 2 on the input screen.
in device manager in ports for the netmos ecp port,on the recources screen i dont get a port adress, this is what shows,


what should i put in the port adress box in the mach3 configuration screen for port 2 ?

in the bios the card shows as an unknown com port.

hi, yes i did. tried configuring the pin outputs for different ways , same thing . changed the length of the step and direction to 5 us  did not work. thank you for your help.i will just remove the brealout board and connect direct to the rutex motherboard.

i think i found the problem. looking at the specs for the cnc4pc breakout board , shows a maximum input of 10 khz. output of 200 khz. try to jog any faster than 60 ipm and the thing is maxed out for speed.
