Hi everyone.
Para
New to the forum and to CNC machining so wanted to say hello and tell you what I'm up to. I'm bound to need some advice at some point so apologies for any dumb questions!
Para
I've been playing with manual machines for a while now and I guess I've taken the pretty normal route? Started with 2nd hand RF30 style machine and a Myford ML7, both pretty good if a little slow. Sold those and upgraded to a MK1 Colchester Student and a Series 1 Bridgeport. Now we could shift some serious metal but the practical boundaries became the complexity of shapes. Added DRO and made some progress with rotary tables and then a compound table on top of those but oh so complicated, slow and ultimately there was still limits to what could be practically achieved.

Started to think about CNC a while back but was looking at built machines, and there was nothing in a practical price range. Looked at converting the Bridgeport but all the advice seemed to be don't do it, plus the costs were still pretty high. Then I came across the G0704 conversions on Youtube and that seemed achievable cost wise and a useful enough size so decided to go that route. Spend a couple of months absorbing info and then starting gathering parts around early December so I could sneak off and fiddle with some stuff over Christmas!

So to bring this up to date. I have an AMAT25LV due in here in a couple of weeks from Amadeal. I've built the control box, using parts from CNC4YOU and have hooked in the stepper motors. All seems to work ok so far (bench test of the motors only).

I wanted to put this machine in an enclosure, the Bridgeport seems to be able to fill the workshop knee deep in chips in no time plus I want to look at coolant. I've started building a stand and enclosure, but some way to go on that yet.

I really need to get much better at understanding feeds and speeds, chiploads etc, I've very much put a tool in and dialled it in by hand up to now with reasonable if varying results. However if I'm going to let a PC takeover I guess I'd better become much more knowledgeable otherwise I'll break no end of tools!

Software wise I've been using SolidEdge for work in a fairly limited capacity for some years so 3D modelling is something I've a basic knowledge of, however I didn't have CAM and it was very expensive. I've downloaded and played with Fusion 360 which looks great so I'll go with that for now. I need to transfer my CAD knowledge over, although the basics look similar. Mach3 for the control software seems a no brainer?
Para
That's me, if it's of interest I could put up a build log. Would be good to get feedback and pointers from those with more experience than me (which is pretty much everyone at this point!)

Cheers
