Second CNC table build, here we go again....

Yesterdays little fun test...



3mm Stainless, 108v, 45A, 3800mm/min, pretty clean...
The bottom 4 lines are on the new table, the top mess is the result i had on the old table which made me build the new one!!!



Test shape, old m/c vs new m/c...
I know the slot is buggered - this was because i used the test file for mild steel and forgot to tweak the settings on the slot part first


You can at least see the waste in the slot, that a 3mm slot and the waste is about 1mm.



So, not too bad today, also been messing with divots, internal holes. Tried a 5mm overburn with the torch off 1mm before the end, so the end of the cut is 6mm from torch off and you can still see a mark. Will keep messing with that one but at least she's up and running again.

I have twisted the torch mount to correct the odd bevel or at least balance it out, I'm leaving the torch at the current angle - it's working so until i find a reason, i'll live with it

30A consumables arrived today, gave them a spin on 1.2mm 304 stainless and got excellent results As good as the finecuts on the 30XP were at least.

Both pics as they came off the table...

Voltage was low as normal it seems, 76v instead of book 98v but speed was bang on at 4000mm/min, pierce height 2.5mm, cut height 0.5mm. Still need to dial the THC in as its a bit unstable on thin stuff but at least it works and the table is now producing paying work.
