My acquisition.

bearings slide lovely, no play

all back on machine, heavily greased (after this pic)

Those rails and bearings look like manufactured by SBC (Take a closer pick of bearings and I'll tell for sure) and if so then I think I've got some bearings kicking around if not I've got access to getting some if you ever need any.

thanks jazz. Il upload a piccy tomorrow

got the Z working!! off its own steam. Using its own power supply its own stepper controller. The other motor controllers appear to be working but the other steppers (Y and X) are eight cable flavour

two green, two yellow, two red & two blue

with the standard 4 core ones, I work out which are the coils but shorting the cables to test for extra resistance in the shaft but these eight core ones blow my mind... has anybody got any idea how I work out how to wire it? Ive got no model number for the steppers and obviously no diagram



oh, and... and as the highlight of all your evenings... here is the z moving

G the video is saying it is private

With the machine against one wall i would keep it, 2' is plenty of room honest

Fixed video.... re machine...I doubt il get rid of it anyway!... 2' wont leave me much space for all my other previous toys ; D

I reckon with the machine you could you could build some timber panels for an extension to the garage ;-)

8 wires means the motor is most likely similar in wiring to the ones on your first machine, that is 4 windings and two per phase. You should be able to use the same method to identify the 4 pairs of wires for the 4 windings, then you just need to know which two are which phase so you can put them in parallel (or less likely series). I'm pretty sure you can safely do that by connecting to the driver and just trying the four possible combinations - one will just work and the motor will only go a couple of steps forwards and backwards with the others.

Is there definitely no part number on the motors?

Right. about killed myself tonight lifting these bad-boys onto the trailer. Tomorrow I intend to drive over to my friends unit where there is the magic "three-phase" I can temporarily wire these in, to proove they work. Then Il put them on the bay. As ultimately im going to need single phase ones in order to use the vacume bed in my workshop

However, can anybody shed any light on what im looking for... how do I tell they work? I assume they are like big vaccuume cleaners... except I wont put my hand near the inlet as I guess it will suck it off? (my hand)
I assume the following

I guess the square blue tanks need to perhaps be filled with water? I say this as their is what looks like a sight glass on the side (labelled E) ...

if anybody could tell me what im expecting to see from each of the labelled ports... and perhaps confirmation of whether im meant to be filling the blue square units with anything id really appreciate your feedback ;)
