All 3 gantries are done with belts and reductions and Z axis mounts and hard stops. No limits yet.
Also all 6 uprights for 3 machines are done, now bolting them to gantries.
All this can also be taken as the procedure to build a cnc machine, start from the Z axis, always. Any other way will lead to issues during the way.

Luckily i did not pay for them, or actually i did physically pay for them after a friend sent that money to me, almost all of the miners i have are his by now, had to sell him the last one i had when i built the new shop. He is very generous compensating for electricity and maintenance.
Back on topic, had a visit today regarding some new builds, they already have the metal construction and some servos for a 12X4 meter plasma machine (chalk that to megalomania) so task one is finishing that one, then another plate cutting plasma/oxy at 6X2 meters and a pipe cutting one up to 400mm and a square cutting one up to 500mm.
Yeah, both tube ones are going to be 12 meters long, so just the moving weight is a huge issue.
Oh joy, more to do...
Who is counting, how many machines am i building ????

Ouch, pretty sure that if you browse back there are two of RX-6900-XT there!also pictured: the elusive high end graphics card

So many holes ....
My whole right side of the body is stiff from all the driling and taping, dang it i had forgoten ....
Finished all 6 of the Y axis (150×150×4), mounted legs (L profile 150x150x3), rails (SBR25) and 2 carriages each.
Pretty sure one of the Bosch drills had enough as it started stinking!
Now some more holes to bolt the gantries and belts, and later to mount the "skirt" = side plates.
Missing 8 of KFL08 bearings for the reductions, waiting...
Also missing a lot of electronics, from Mesa boards to drives (although i do have plenty of drives but full step or half step only = noisy), thinking of switching one to servo as i have some small 20 to 80W motors and some "arduino" drives and from previous testing they work nicely when paired with a Mesa 5i25/6i25 or 7i92, but will require more shielded cable that is very hard to find here, before used some "camera" cables but it cr@ps out after 2 to 3 months of use so no more.
More pictures to follow ...

This is the current state of the 3 ongoing builds, gantries are not bolted to the Y axis yet, same for the reductions (might mount them today, who knows ), the design>cut>paint>mount the side skirts/panels, and that should be it ... for the mechanics since electronics are still waiting on the table or somewhere around the world!
Powder coating came out really nice this time and got done in 5 days so me is a happy camper.
Also a video of the big new shop that got small fairly quickly !

Tommy - looking impressive as always. On the gantry beam that has the single linear rail, would it be possible to see a couple of pics of how you are mounting the drive motor, reduction gearing and the belt connection. Im debating with myself on different layouts for this and seeing how someone with vastly more experience has done it might keep me from doing a dumb ass design choice. ie over complicating it.

Wasted nearly two days with it but could not shoehorn reduction into 70X80mm area, not even with a Nema 21 motor, also had to use 6mm wide belt as the space between the Z assembly and the gantry is 42mm minus 8mm alu plate minus some tolerance ....
It did not go well, at all, so it is directly driven with said Nema 21 Sanyo-Denki 1.8A motor. It will work but not a good solution by any means, HGH25 carriages have wipers on both sides so they do require some force just to move them, do not want to have to clean the rails before every probe just to be sure a spec of dust does not cause it to skip steps!
The rest has reductions, so pictures tomorrow, might want to remind me as i might be spaced out a bit, my youngest brother is also moving to USA and he is off tomorrow evening....
