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

[Desertboy]

That's the plan, but I have a project that needs the extra Z travel I should have 12cm now but to get any more I need to rebuild it as the gantry height is the limiting factor. I'm going to use my machine for this project if I find the Z travel to be a limiting factor then I will have to sort it. I have a few ideas how to carve it up so I can get away with 10cm travel but until I start carving I won't really know what I need lol.

The next month or 2 is learning how to cut with it and then tests cuts, I have no illusions the more complicated stuff I want to do is going to take me months to work out how to make lol. The woods are very expensive to work on so lots of test cuts and scale models first ;)

What I have no idea is what bits to use to mill the woods, was planning to use 2 flute router cutters for the roughing and ballnose end mills to smooth off.

What I really need is a 5th axis and 40cm of Z but that's not happening but I can dream ;)

Wow :D

My mind is more limited.
I can't for the life of me come up with a project that requires a 5th axis :)

Well.. if I were to start building engines and stuff maybe..

What sort of things do you want to make with your router?

I foresee alot of signs in the beginning. Wood and lit up acrylic ones.
As I learn feeds and speeds for my machine I plan on doing boxes, cabinettes, giftpackages and such.
I'm just doing a hobbymachine, should I come up with a sellable product it would be awesome :)

that's with input voltage 252v today so happy with that ;)

Added 2 shelf brackets and setup the monitor, keyboard and mouse in a comfortable standing up position.

Need to set the jumpers yet on the drivers so the Z axis motor was running hot lol need to setup them up tomorrow and going to try setting the bottom axis up need to work out how to set linuxcnc up for 2 motors for the 1 axis.

Then homing of course, come on AM882 I'm ready for you now and machine is itching to get cutting'

[Desertboy]

Back's killing me today so not a lot is going to happen but did pick the spindle mount and Z axis plate up ready to refit I now should have the full 13cm Z travel I originally planned.

[Desertboy]

Trying to work out how to setup the bottom axis something to do with joints in the .hal file I think or .ini

my 12v PSU came fits perfectly in the bottom right corner (White box) and fitted another barrier terminal for power in, have the current limited thermistor as well will get that hooked this evening.



Where's my AM882 Mr Postman starting to wish I'd ordered EM806 instead but thought I might as well stick with AM882's all round and was 1/2 the price for what appears to be identical driver.

[Desertboy]

The current limiter thermistor came so hooked it up and turned on the PSU came one OK although need to test it with load of course.

Now need to wire it through the mcb type b then through the resistor and to the transformer and see if it works ok, now we get to see if I got the right one lol was quite confusing which one to get.



Can't do a lot more until the last AM882 comes although getting it to move the dual ballscrew axis would be good, have got the fan holes drilled now.

[Desertboy]

Got the MCB hooked up and the current limit thermistor and it all works perfectly ;)

MCB 6amp type b, trips without the thermistor doesn't trip with it. PSU appears to be running fine have to wait for the AM882 to come so I can test it under load but should be fine. The resistor is rated to 5amp once it's up to temp.

Is there any point adding a slow fuse as well now I have working MCB type b protection?

The 12v PSU doesn't go through the MCB only the toroidal transformer.



This is the correct current limited thermistor for a 1kva toroidal transformer

If anyone else is interested.

I notice when you turn the transformer off the AM882 stay lit for about 5 seconds and when you test the capacitors when you've turned it off they're ready 7v's so it's good to know the capacitors are mostly discharged by the AM882's at switch off although I might still add a resistor.

Nice work with the thermistor!

Just have one question.. do you still know where all those cables go :D
Lots of connections in a very small space ;)
