Building or Buying a Wood routing table.. Beginnners guide.. / Re: 6040z water cooled spindle motor rust inhibitor

I use the corrosion inhibitor made by "TECTALOY" and it's called "XTRA COOL".
Product # TEX500, 500ml treats 10L of coolant.

I have auto radiator additive in my spindle at about 20% ratio.
I don't have any chance of the coolant freezing, so just went with the corrosion inhibitor.
Our normal drinking water is very good, so didn't bother with distilled water and haven't noticed any ill effects.

General Mach Discussion / Re: The solutions to my false limit switch triggering issues

The thing that gets me is, you can do all the correct things by the book and still have problems.
I don't run any shielded cable on my machine. I run all my motor wires and switch wires through the same cable tray. Initialy I had false triggers happening, but simply installing some 0.1uf caps on my switch input terminals, all has been good for years now.
I must admit that I delibrately didn't run my spindle to VFD cabling in the same run though. I have those cables and my camera cable coming down from above the router spindle.
My rebounce setting is set to 200.

Or it could be that you have "Exact stop" selected in Mach3. Try changing to "CV" instead and see how you go.
Have a read of the first parragraph of this document.

Thanks for sharing. Love seeing jobs where you have to think outside the square to get them done.

I had the oppitunity years back to visit my brothers machine workshop before he passed away and he was refacing a 6.5m dia cable spool that sat on the top of a coal mines dragline.
The spool took a week to position onto a 2x post horizontal lathe.
To align the spool to the face plate, you walked down a tunnel and into the centre of the machine. Special wedges were placed around the machine to adjust the runout before machining.
The day I was there, I was watching in awe, as the twin cutters were creating razor wire like swaf.
I can't remember how long the machining took, but it was a continuous 24hr shift for the guys till it was finished.
He also told me that the lathe ran off a huge style battery bank. The reason for this was in case of a power outage, the battery system would allow enough time to back the cutters off the job, otherwise the cutters would get smashed due to the depth of cut they were taking.

It certainly made my machining jobs pale into insignificance.

Can you share the model of Celestron microscope ?

Model # 44302 is the one I have.

Check your port address is correct in the new computer.

Glad I could help.
Any inconsistent results would suggest either your measuring equipment or technique is flawed or you have backlash in your axis's.

In that case it sounds like you may need to recalibrate all your axis's.
There is a function that walks you through setting up your "steps per", so that your axis's move the correct distance they're told.
You'll find this function in the bottom left of the "Setting" screen, just above the reset button.
When it asks for a distance to travel start off small at first. Once you save those settings do the calibration again using almost your machines maximum amount of travel.
The longer the distance you use to calculate the steps per, the more accurate the calibration will be.

In the box next to the DRO's in the program run screen, what is the scale set to?
Do you have your native units in Mach3 set correctly, MM versus Inch?
Did you use the correct postprocessor for your native units when saving the toolpaths in Aspire?
