The way I read the manual the inputs will take up to 30V there is a 1k Resistor in circuit that will limit the current at 24V to 24mA so not a dead short. Dean will no doubt pop along and give you the advise re the Estop and that bob. ..Clive

Hi Paulro Clive brough this to my attention did you get this sorted.? . . . If not what's your fear with releasing magic smoke.?

Hi Jazz, i couldn't visualize the e/stop to the BOB and the e /stop hard wiring combined, as well as that i was reading up on the fault signals from the drives and read a post in a thread concerning dead shorts. i just got the two completely mixed up . i think i have it under control now . i have the wiring nearly finished bar the override and buzzer. i might try and configure Mach3 which i downloaded a trial version of. i 'm not sure if i should power up the drives and then configure Mach 3 or leave the fuses out until i get Mach 3 configured and then power up . Or have i misunderstood the process of powering up? or should i power up 1 drive at a time and configue Mach 3. to be honest i'm at a loss as to my next move now that i have the wiring complete . i have the belts off the motors until i get them to turn. i suppose i'm being too cautious perhaps?

Ok well a good bit of caution is wise policy but you have no need to fear mach3 it won't do anything unless commanded too.

First thing to do make sure control box is wired correctly and all drives power up. Check the E-stop knocks the drives out when pressed.

When sure control side is ok then set about setting mach up.

First place to start after installing plug-ins etc for motion control card is in Ports n pins by setting any input pin numbers for Estop etc. Without these set Mach won't come out of reset. If want leave Homes and limits for later but E-stop will most likely need setting.

Next set the pin numbers for each motor in Motor Outputs. Then goto motor tuning and set the Steps per based on your Micro stepping setting and ballscrew pitch. Choose a low velocity and Accelleration for starters. 5000mm/min & 500s/s are good starting point.

You should now be ready to go for testing.

i have the plug in for motion control loaded and the bob powered up with an e/stop signal (n/c) . i have set the pin no. for e/stop in port and pins set to 10 , port 1 but still can't get Mach 3 to reset. i keep getting '' External Estop Triggered'' the hardwiring for the estop is as follows.

any help would be welcome

i have the plug in loaded and the bob powered up . the e/stop pin set to 10 , port 1 but i cannot reset Mach3 . i get the message'' External E/stop triggered. the e/stop is wired normally closed as per dwgany help would be welcome.

Set pin 10 to active low (green tick) then it will work.

**PAULRO** · 30-04-2015

cheers Jazz, i watched the first video on the Mach 3 website and got mislead , again!!! the green tick( active low) did the trick o.k. i need to give the tutorials another glance again to see if i can get the motors to turn!!!
