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

[Desertboy]

No worries, now have upgraded to 2.8 and got 4 joints configured, Y is linked, X homes, one of the Y switches works, one doesn't. Have control of the machine can run code.

Got driven home by the cold spent a good 6 hours with the machine but no heating and in a large industrial unit it took it's toll on me lol.

Hopefully can work out how to configure my second homing switch have the .ini and .hal with me this time to post up on linuxcnc ;) so hopefully can work it out tonight I was getting close when I left.

This is how close X gets when homed now (I have it click the homing switch and travel another 50mm)

If you see the spacer at the top is slightly loose it's because the bolt's too long by 0.5mm need to strip the Z off and shave the bolt down to sort but need to order the bits I need to add grease nipples to the Hiwin's so I can do at same time. The actual spindle is still rock solid but obviously going to sort out.

And this is how close the Y gets when at maximum travel +(700mm) although I still have 5cm to play with on the other side of the bed I think 70cm travel sounds good. It's freaky watching it plough full speed towards the end to then stop so accurately and quickly so close to the end.

Now I've got homing working

Good work, follow rodw with his amendments I think they are correct. Just one point I noticed in the ini file is the z offset I think you have it at 0 it might be better just off 0 so as to not have false triggers.

Will be doing this morning when I can drag myself back to work, I have no homing switch on the Z so I manually home. Will need to buy bigger energy chain to sort, also need to make a better mounting plate for the energy chain on the Y axis which isn't straight and keeps coming apart. I suppose I can now use the machine to make that bracket but probably just measure, mark and drill.

Very impressed with the cut from the 2 flute 6mm end mill on the laminate I was expecting mega chipping.



Because I only clamped one side it wasn't even so the white wasn't milled out properly but it was only a test with some scrap so happy how it came out as soon as my clamps come (Ordered 4 toggles clamps going to use 2020 extrusion across the bed instead of steel.)



Need to flatten the mdf bed as well, gong to get a 1/2" trend straight router bit to do this as it will be a lot quicker.

Be quicker still with a 50mm https://www.wealdentool.com/acatalog/Surface-Trim.html or similar

It came so fitted it, think I'll put it sideways on though so I access the flip for changing bits easier.


Had a find ;)



There's 1 more piece to come

60*60*3mm box section steel 2.1m lengths going to use this to upgrade my router so work isn't finished yet lol but it'll take me a few months to raise the money for 25mm Hiwin's, proper R&P for the 2m axis and I want to swap my gantry ballscrew to a 10mm pitch. So plenty of time to play with her for the time being. I'm thinking of taking my gantry and dropping it on a frame made from this. I have loads of 40*40*1.5mm box section I can use for bed supports (Again free, sometimes it pays to pikey everything you see lol even if you sit on it for 3 years)

My favourite price free ;)

This will offset the not free stuff I had to buy lol

ordered a cyclone was going to homebrew but price was too good to bother.

and got a vacuum cleaner finally I had 3 2.2kw but wanted something a bit more reasonable to run so gone with a 1.2kw miele with power control can drop it as low as 250w cost free ;)

I noticed that your cy cable to the spindle is not secured in that every time the Z axis moves the cable gets bent at the plug. This is a major fail factor and might destroy the VFD as has happened a few time here. Can you put a supporting bracket from the Z front plate to fix it.
