Vfd an d spindle is here! I have to find time and connect them to test if everything is ok. Is 1.2 mm non shielded wire ok for connecting vfd with spindle?
For corrosion prevention do I have to use solution of car antifreeze liquid with water? I have read somewhere about a solution of a special anticorrosion oil with water....

I have a 2.2kw from solar jean I never added anything to the water still coming out clear in the pipes can't see anything in the bottom of the tub I have clear lines which is not good get black ones if possible (Algae).

I have an ozone pond cleaner which I'll add when I remember lol this will eliminate algae and in the abscence of visible corrosion in the reservoir I'm going to not worry lol.

I used 1.5mm but reading up 1mm would be fine as well BUT you need it shielded (CY) VFD creates a lot of interference and the most likely thing to cause you issues in the cnc.

I haven't shielded mine YET and seen no issues but I would not cut anything properly until I have (I only need to connect to earth, it's all in place)

Thanks for the reply Desertboy, I will go for shielded cables then, the cost is not much higher than the non shielded, so it is better to be CY and block all interfierence that I can.

All modern VFDs use power devices known as IGBTs. These devices make it possible to minimize annoying audible noise by using switching frequencies beyond the audible range. Unfortunately, VFDs using IGBTs, present a high potential for generating RFI - Radio Frequency Interference.

I've been waiting for 42 days for the T slot nuts to come from China and finally come and with them the frustrating reality!
Nuts was shorter by .20 and this make them turn and not lock in the aluminium slot!
I cover the T nuts with self adhesive tape and solve the problem, this took me one day to think it since my nerves was not in good condition,as I was keep thinking that if I make a new order, it will take another 40 days to arrive!

Put the rails on the aluminium extrusions and run the caliper.

I'm going to glue 2 T nuts together so they can't twist in the slot for my clamps to make it easier to release, move and retighten.

Is that M6 thread with a 10mm slot?

Smart stuff ;)

Or you can just buy the longer ones?
They cant be "dropped down" but thats true if you glue two aswell

Those are M6 with 8mm slot, they was suppose to be 19.5mm but actually they are 19.28mm.

Why didn't you write that yesterday???
