OK, Id like to have all the peaces together in order to get it moving at the weekend... or atleast try! assuming I can connect the X ballscrews and all the steppers this week I think it may be possible.

Ive also, for now decided to drive the X with dual steppers... rather than the single stepper long belt approach. Only because its easier (long story) Ultimately I may change my mind on this at a later date... but for the purpose of getting it initially going... 2 steppers it is...

So, I have already got
1 x 500w linear power supply from Zapp PS806-5 Linear power supply.
4 x DQ860MA 80v drives Stepper Motor Driver DQ860MA:Stepper Motor Driver DQ860MA wholesaler

Im going to buy hopefully today in order to get delivered for weekend
1.5mm2 cy cable CY Cable - 4 Core 1.5mm2
2 x steppers for X axis 3.1nm (will these be powerful enough? it weighs a ton!) Nema23 Stepper Motor 3.1Nm
this breakout board? Im open to advice Breakout board CNC Stepper Motor 5 Axis Spindle Relay HG07
1 x estop? Red Mushroom Emergency Stop push button switch NC 400V 6A

For now, until the machine is done and I can machine the face for the box all the electricery are in, im going to wire the steppers direct to the drivers rather than going via connector blocks. However I notice on some of the other builds fuse boxes are used... where about in the citcuit should I incorporate a fuse box (I assume after drivers and before steppers) What fuse box & how many fuses do I need etc?

Not sure if that breakout board is any good?

Can anybody recommend anything else im going to need.... or wish I had?

really appreciate your replies... reply even if you dont think you have anything to add... your probably going to know more about this subject that I and Id appreciate your thoughts....

ps - if anybody fancies a trip to leicester on sunday to be involved in a firing it up... all welcome pm me
