Newbie looking at 6040 (China CNC) for polypropylene 15mm sheet

[Boyan Silyavski]

DDCSV1. It started as a joke, i just had returned the Pokeys57cnc and was wondering what better controller to buy. I have written a lot in the forum about said controller use search function in forum. So at the end it worked so well i did not feel the need to buy the more expensive offline controller i had in mind.
But back to Mach3? God No. Only for special purpose machine where/if i can not avoid it in any other way.

I have basically 0 min downtime last half year in workshop and thousands of things done. I had at least 1 week downtime /if not more/ the previous half year . And the last 5 years if we put together the time i have lost installing windows, Mach3, reconfiguring, boards, plugins, figuring how to make things work...I have lost a couple of months with Mach3, plugins and boards.

So because I lowered my stickout with the new roughing bit and pretty much all the others, I forgot to lower my spindel to compensate.

Which meant it was hitting the Z limit thus not going lower than 10mm.

Need to work on this 2mm bit.
I already use the rouging bit to hog out most of the material. Just need more square holes.




Here it is from the other side.

Well you can't make a square hole with a round bit, so if you need it more square use a smaller bit.

...or overcut into the corners and have a bezel to hide it!

That is why I step down to a 2mm bit.
All the holes are different in that I tried different things with them.

The middle one worked the best as the buttons are not fully square themselves.

[Boyan Silyavski]

Maybe its wiser and easier to drill the corners first. Then pocket with the bigger bit.

[JOGARA]

Not perfect but I think I have got it down pretty well.

I don't have a 3D probe yet so whenever I reset the machine I am obvious out somewhat.
The last operation of cutting out the case was well out for some reason..





I am working now on setting up a spoil board underneath the stock to then super glue my stock to.
This means I am not cutting out something floating in mid air.

Just another bit of aluminum stock will do that I can then glue my work stock onto with super glue?
