General Mach Discussion / Re: Mach 3 hiccups - Please Help

Ok guys it happened again!

I haven't touched the coolant switch this time.

It adds .05 to all my tool offsets and the part is junk.

I checked the tool offsets and all the math works out.

It's leaving my part .05 short and the offset is .05 long.

I haven't had time to do any thing about this other than
not messing with the coolant switch.

I have about 250 more parts to run before I can shut down
and make any changes.

I may have found what is causing this.
The Tormach has a control panel with
a bank of rocker switches one of the
switches turns the power ON/OFF to the
PC. this switch is fed 110V straight from
a 110V outlet. The coolant pump switch
has three positions NO/OFF/AUTO.

When you select the NO position it gets
it’s power from a jumper that comes off
the back of the PC switch to manually
turn on the coolant pump.

When you select the auto position
the power for the pump comes from
a circuit board that has a rely that
switches the power ON/OFF when
M codes are used.

I think when you manually turn the
pump ON&OFF it is doing something
funky to the PC’s supplied power an
causing these strange problems.

I can do one of 2 things,1 run the pump
it’ on power wire or 2 put the PC on a serge
protector.

What would you do?

I think I’ve found a design flaw in the wiring.
I’m too busy today to go into detail and my
kid has a ballgame this afternoon.

I’ll go into detail tomorrow afternoon.

Ok guys I found out that the M codes controles a relay and the switch DOES NOT.
I opened my cabinet and played with the MDI trying to fined the relay and noticed this!

I'll give that MDI a try today.
I have 80 parts to run so it will have plenty of opportunity to show up.

The relay controls the pump ether way but i only notice the problem when I use the switch.

The relays are on a board so would I put the diode in line with the switch?

Ya I think it is controlled by a relay.

What is a snubber?

This is a question about Mach 3 and my Tormach.  I have a program that has 4 tool changes in it and I'm using M commands to control the coolant.  In between one of the tool changes I manually turned the coolant on so I could aim the nozzle for that particular tool.  Then I switched the coolant switch back to auto and pressed cycle start.  The machine started to move and did not turn on the spindle.  The next time I done this a couple of parts later, I hit cycle start and the spindle started as it should and the tool run through the program but the part was about .050 shorter than it needed to be.  I have noticed strange things like this in the past but I never could figure out what was going on.  If I mess with the coolant switch in the middle of a program this thing develops a hiccup.  If I leave the coolant switch set to auto everything runs as smooth as glass.  Is there a software update that I need to download?  Or do you have other people with similar problems that haven't figured out that messing with the coolant switch has caused this.  I know it sounds strange but this is the only thing that I'm doing different while running the program and every time I mess with the coolant switch in them middle of the program something odd like this happens.  When I say I'm messing with the coolant switch - this is while the machine is setting idle in the middle of a tool change. 
 
Thanks for your time.
Have a good one.
Chris

I deleted the Q from the post with no luck, it cut the hole the same.

I left the liner motions unchecked and put check marks in the other 2
and it cut a nice hole.

Thanks to all that responded to help me resolve this.
