Flood coolant wiring " NEED HELP PLEASE"

[Gregory_C]

If there is anyone out there that has wired there X4 for coolant. I am sooooo FN lost and if i had pics i could just go off of that. Anything right now would help thanx guys.

Looks awesome, but too clean. Soon it will acquire some chips and other signs of doing it's share of the work. What kind of parts are you planning on making with it? We'll be looking forward to seeing some of the work you do with it!
Best regards,

Mostly alot of small stuff like this all made from Ti

An additional note the the whole flood coolant system. Now this could just be mine, but I'm fast losing confidence in the control system. I'd noted a few times the spindle to stop when the coolant came on. Thought I'd got over it by allowing the coolant to get going before the spindle started. This doesn't appear to be the case as I got a message for the first time of Err in the mill display and no spindle rotation...not that that stopped it from trying to continue to execute the code and drive the drill into the work. Thankfully now my hand seems to spend most of it's time resting on the external emergency stop switch when it comes to using this thing!

I'm looking to remove the control of the pump from the mill electronics as they're looking more and more flaky to me.

I don't have the Syil stuff, but if you want to work completely around the OEM stuff, it is pretty cheap to do so. Especially if you have issues with the onboard relays.

I found a nice solution at Surplus center.

Very easy to hookup and install. I am using one of these on my router and now one running my coolant on the mill. No interference with the spindle code at all.

When a spindle stop is issued with program end via M30 a M5 (spindle off) and M9 (coolants off) are issued.

It sounds like your coolant logic needs changing from active high/low to the opposite mode in the outputs setup.

During program run M5 does not stop coolant so this would explain why it happens sometimes. Also if X4+ is put from manual mode to CNC, the state of Mach3 may be commanding the pump to be on.
When switching to CNC mode, hit reset on Mach3 first to if this makes a difference.
Try executing individual MDI commands to determine what is happening.
Manual operation should at least stop obscure program sequence things from confusing the issue.
M3 S1500 (start spindle)
M4 (reverse)
M5 (stop)
M7 or M8 (mist or coolant on)
M9 (coolant off)
M30 (M5 and M9 issued)

Set your Z inhibit to a safe value while testing.
If Mach3 is not responding to the E-S signal from X4+ then feeds won't stop. Make sure E-Stop on X4+ makes Mach3 go into E-Stop mode. Use the diagnostics screen. Should be pin 11 if I remember rightly. not pin 10.

Sounds like a few settings in you .XML file are not up to scratch.

Thanks your input Neil. Greg, sorry for what seems like a thread hijack.

Typical the mill from turn on (with or without the PC & Mach3 running) will do one of two things, either nothing or if the switch is left in CNC speed control the spindle will pulse on and off at what I guess is the minimum RPM. Normally this does slowly decrease to nothing. At the same time it'll pulse the coolant relay and you get wet if you're no aware that it does this! Sometimes in CNC mode when starting the first program from cold it will go to requested speed in reverse and then it'll suddenly change direction when it achieves the target. Spin up is dreadful at the best of times but I've put a long dwell in just in-case it does the reverse start.

As I've had the glitching problem mid-program during tool changes and the way's to recover it vary from power cycling the mill to close and restart Mach...that always pleases me.

As I reckon I'm going to need more IO in the future I'm going to add a second parallel port and breakout board for all other operations.

This is a snippet from a program run today, ignoring the G90, this how they always end (assuming coolant is being used):
N210 G00 Z50. M09
N211 M05
N212 G90
N213 M30

A snippet from a typical tool change:
N25 Z50. M09
N26 M05
N27 (CUT EXTERNAL DIMENSIONS)
N28 T3 M06 ( 10. FLAT ENDMILL)
N29 (MAX - Z50.)
N30 (MIN - Z-12.5)
N31 G00 Z50. M08
N32 G00 X-53.5 Y-76. S3500 M03
