Mach4 General Discussion / Re: Mach4 Limit Error on Power up (Switches are automatically set to 'Low')

« on: May 27, 2017, 12:11:12 AM »

hello question what controller/bob are you using i just set up the mb2 after having my ess set up on another bob and i had to change all the settings basically take control and change in the ethernet smooth stepper plug in. before i did that inputs and outputs were coming on when machine was turned on. after that everything came into alignment.

Mach4 General Discussion / Re: ESS Diagnostics System not responding

« on: May 26, 2017, 11:19:52 PM »

hi i will tell you what i know of ess diagnostics which isnt much. back a few updates they would just hang the machine so that leads to my first question do you have the latest plug in installed if not that could be part of your problem. next why do you want to have three seperate mpg (not judging just curious) on my mill setups i only use one mpg and have a rotary switch to select between axis and a second rotary switch to select increment. i do know of some lathes that have two mpg. also and i could be all wet here you set the mpg up in plug in setup and mach 4 not diagnostics. try that good luck

Mach4 General Discussion / index homing mach 4

« on: May 26, 2017, 11:08:12 PM »

hi all i have a quandry. i am upgrading a bridgeport to mach 4 with new ac servo drives a vfd the ethernet smooth stepper and the mb2 break out board which i absolutely love. the problem i have is not enough inputs but then you never have enough. so i built a daughter board to take the index signal 5v from my drives and convert it to 24vdc through an opto isolator this works fine. next i need to use only one input with my setup so i added a multiplexer to the daughter board i have plenty of outputs. i hooked two outputs to the daughter board with the mutliplexer and on/off combinations turn on the index from x y z a drives. the smooth stepper homes to the index perfectly. i need to set up the outputs so that when i am homing X a off b off, homing Y a on b off, homing Z b on a off, homing A a on b on and i havent the foggiest idea how to do this. i have been looking at the lua scripts and realize i do not understand how homing is programed. in mach 3 would have been change vb. so if anybody can assist me in this endever or point me in the right direction it would be much appreciated thank you

Mach4 General Discussion / Re: Mach 4 won't run constant Estop - HELP - Log File Included

« on: February 25, 2017, 12:12:39 AM »

hello
i recomend you start with how does pokeys or your breakout board recieve estop look at that input check the wire to the switch pull the wire out of its connection and test the wire to ground or short. activate the switch check with meter see what happens ie does the wire change state when the estop is pushed. also what kind of estop does the switch report back to a relay then the relay informs mach or does it have a straight connection to the breakout board.if i were getting random estops the first thing i would check in great detail is the estop circuit. pay attention to the estop switch i had one that would stick finally replaced it. start there if that makes any sence if not post more detail about your estop circuit. is the wire shielded you can also add a capacitor .1 uf across the input terminals to debounce the switch. good luck

hi how was the button added to begin with did it come with a screen set and did you restore from a backup. if you restored from a backup it should be there. can you get into the old hdd at all to get your backup. that should be a good place to start

Mach4 General Discussion / Re: soft limits z axis mach 4

« on: February 24, 2017, 08:37:59 PM »

hi i just figured it out!! the home offset is a positive because it is over machine coordinate zero the distance off the home switch is positive. reply if you differ.

Mach4 General Discussion / soft limits z axis mach 4

« on: February 24, 2017, 06:34:03 PM »

hello
z axis behaves strangely. i set it up soft min -5.00 soft max 0. home offset 0. i have also set it up soft max -.125 and home offset -.125. i have also set it up home offset .125 this worked even though it seems wrong i want to set z to move -.125 off the limit it doesnt seem to do this. if i set to home offset -.125 and home my machine will crash z if it doesnt it will still not work right. to me home offset -.125 makes sence if anybody has a fix or an explanation of why this is please. i am running a bridgeport stepper knee mill with ethernet smooth stepper and a cnc4pc c62 break out board thank you

hi did it to myself once go to your startup short cut and change the /p to /e this will boot you directly into the edit screen and you can change it. says that in another post just about pulled my hair out over that.

Mach4 General Discussion / Re: M4,ESS and Limit/Home issues

« on: February 03, 2017, 06:25:09 PM »

hello two things come to mind i have used c10s in the past one thing you can do is place .1 micro farad capacitors between input and common for inputs pins 10 11 12 13 15 this will help to settle things. next how are you wiring your limits individual or daisy chain. i would pull my wires off the c10 and with a meter or continuity tester see how they behave individually and check to machine ground for short. good luck

hi
with a little push in the right direction from brett i added this to my plc script seem to work fine

-------------------------------------------------------
-- Run Lube
-------------------------------------------------------
local inst = mc.mcGetInstance()
local hsig,rc = mc.mcSignalGetHandle(inst, mc.OSIG_OUTPUT0)
if (machState == 0) then
mc.mcSignalSetState(hsig,0)
else
mc.mcSignalSetState(hsig,1)
end

thank you
