New build with recycled parts on a ridiculous budget 120cm*60cm work area

I take it I'm building an unregulated PSU?

Going to buy the bits you linked to from rapidonline ;)

I'm reading Joe's excellent thread right now but started at the beginning of the thread so taking a while to get to the PSU posts but I think I've got it sorted in my head had a good read around other sites and it seems really simple.

Transformer steps down the voltage, bridge rectifier converts it to DC, capacitors smooth out the DC more capacitors smoother DC.

Looking for a suitable terminal block like Joe has I found them on ebay but take too long from China so need to find a UK equivalent.

e2a found some

Clive S would it be worth getting a pci parallel port and a 2nd breakout board? Cost is only £15 for both. I have no idea how to wire up and configure one board never mind 2 lol.

:)

Ordered bits for power supply £90 in the end

I got the 25v transformer you linked to Clive only 1 left now ;) I also got 4 capacitors instead of 3, capacitor holers, some barrier terminal connectors, bridge rectifier and 5m of red wire, 5m black wire 2.5mm core.

Now I have no excuse not to have the power supply working before the drivers come.

Had to order 3 more sets of bolts to finish building the router they will be here Friday most of the Z axis is built up now my travel is pitiful around 7cm. If I remake one of the Z axis plates I can get almost 17cm of travel so will do that shortly need to score some 20mm thick tooling plate don't fancy paying £15 delivery on £8 of tooling plate lol.

7cm is actually more than enough for what I plan with the machine but might as well get the extra travel sorted sooner than later and an interesting early project for my machine.

They've shipped everything except my cabling which will be a week :(

That's really annoying eyeing up my heated bed on the 3d printer that has 2.5mm wire and would give the excuse to swap the red mk2 heated bed to the mk3 I got ages ago but never wired up.

Z axis, I need some bolts to finish it off they were ordered yesterday will come tomorrow. I could have used normal bolts but since everything is A2 socket caps I thought I might as well stick with them and buy more. I haven't cut the Hiwin's down so I can remake the Z axis to get more travel

Finally worked out how to fit energy chain, no way going to fit my water lines in the chain but at least the wiring will be ok, glad I bought chunkier chain for the Y axis as it will have another cable in it.

Parts came for the PSU this morning will build up over the weekend hopefully, I bought 4 capacitors instead of 3 should I fit all 4?

Personally I would only use 3 caps. Re the pci PP it can't do any harm. The attachments above don't appear to work.

I bought 4 because I wanted a spare so I'll go with 3 ;)

the company I bought 4 AM882's from contacted me today they only have 2 so told them to ship them and refund the difference and bought 2 from HK angry though as I was expecting them to arrive next week now going to be at least 2 :(

When I finish the router and it moves properly I'm going to buy 1 3nm nema straight away to swap onto the X so I can swap the 2nm to the Z axis as I have a gap is bigger than I thought between the ballscrew and nema and the longer shaft of the 2nm motors are a perfect fit.

Still got to drill the spindle mount out, bolts are going through the spindle mount them through the top Z axis plate, through aluminium spacers and into the Hiwin carriages directly.
