I was curious if anyone has come up with a replacement conduit for the X axis stepper motor? Mine is in bad shape and the coating is hard and peeling off, I cant see replacing it with the same as whats on there as its not holding up very well.

thanks for any input

McMaster-Carr sells Liquid Tite conduit in various diameters and one of those should work. Grainger might also sell it if they are close enough to pickup.

Thanks Mike, I was just wondering what others had done, This one has lasted almost 8 years, thats pretty good service life.

Well, it's not a Tormach, but for my Shizouka AN-S (really big CNC knee mill) I'm just using regular liquid-tight flex conduit I get at Lowe's or Home Depot.

( I posted this in the wrong thread... twice...)

After the problem I had with mine cracking for the x'th time I've been looking at different options, problem is how flexible the original stuff was and how stiff some of the other options are
This "Type LNMP" or "Type LT" conduit but I'd like to physically touch a piece to see how flexible it is

Does it do any movement, if so it has to have a flex rating, the liquid tite conduit they have suggested is no good if you have any flexing or axes movement

This one is best if you have any movement there are many different suppliers for this PMA Conduit https://new.abb.com/low-voltage/prod...s/pma-conduits

The "Type LNMP" or "Type LT" ones I mentioned are both rated for continuous motion, oil resistant. One is metallic while the other is non (I think)
I don't think either would be as floppy as the original (which has lasted a lot of years honestly) but being slightly stiffer wouldn't be a bad thing I believe

IF you have movement it won't last very long at all it is great for a static install so if you have any movement at all don't waste you time, always look at the application they list for the different types of conduit most you will see is for static installs for this type of conduit material type also plays a big part of the flex rating

Type LNMP
This UL and CSA listed nonmetallic liquidtight conduit is ideally suited for continuous flexing situations. It is often specified in “Power Track” or cable carrier installations and on industrial robots. It does not contain a metal core which could fatigue from repeated flexing or vibration.
Flexible PVC
Resistant to Oils and Mild Acids
Flame Retardant
Sunlight Resistant (UV)

Type LT
A general purpose flexible, oil-resistant, non-UL spec grade liquidtight steel conduit designed for a variety of installations requiring motion, vibration and bending. It offers good mechanical and moisture protection to enclosed conductors.Flexible PVC
Flexible PVC
Flame Retardant
Sunlight Resistant (UV)
Liquidtight Oil Resistant

You obvious have never used this, the LT you would never be use for any thing that has movement

Only this one is suitable in the LNMP with a PVC outer and Nylon Inner
