That's what I've ended up with anyway, along with a few other bits and bobs from a school job lot. I'm only interested in keeping the Boxford for making motorcycle parts, as part of my hobby/business - I restore older motorcycles or stick two stroke engines in newer ones. Anyhow, I have one of these:
and one of these:
I think the little Denford is a bit too small for my purposes so of the two, I plan to hang onto the Boxford.
So hello first of all and secondly, assuming these machines are in good standard working order, what do I need to get them going?
Normal procedure is a guts transplant. keep the steppers and spindle power and replace everything else with new drivers, breakout board and PC running Windows/MACH3 or Linux/EMC2 or a few lesser favoured flavours...
That seems a little severe! What is the reason for that? I assume the machine is capable of creating simple shapes, brackets etc. as it stands. Perhaps when I become a little more creative I can think about upgrading the Boxford. At the moment I just want to drive the Denford, prove it works and sell it on.
I am looking at the Mach3 software at the moment as it happens but I haven't got to the bit where it needs me to "rip the guts out". ;)
Here is my understanding:
I need a physical connector either a serial or parallel lead, either to the serial or printer or USB port of a suitable PC
Machine specific driver for the above for the Denford or Boxford (or is the driver universal?)
Machine control program (Mach3, VR Milling, <something else for the Boxford) I assume this program handles the 3D model to machine control interface
A 3D design package (I am a Google Sketchup expert but I don't think that's gonna help!)
I have some experience with PC packages and 3D packages and I think I'll be able to unravel the process for inputting this into a CNC device. It's early days though and for now I'd be happy to be able to simply dirive either or both of them with a very simple program just to convince myself they work.
bare minimum to get the boxford going, is a breakout board and a 0-10v spindle board or one combined £55.
I'm missing a reply pending moderation. I'll redo it if it doesn't turn up...
Don't worry we all started where you are.
Most home/hobby/light industrial conversions on these machines remove the existing old outdated and slow controller, and replace it with a computer with Mach3 installed as a controller.
This uses the parallel port as a machine controller, this uses a breakout board to interface the computer port to the existing drivers and relays. The spindle will need a specific board (0-10v spindle board) to interface the speed control from mach3
Thank you. Yes that makes perfect sense however at this very early stage and still by way of "introduction" ;) I should explain how I operate for example with motorcycles.
I like to buy "project bikes" which usually turn up in a variety of plastic buckets. I buy them super cheap and, if it's a buy to sell, I'll pick a target value and perform a rebuild/refurb commensurate with the equity. The more they are "worth" the more time and effort I can spend on them. I think you can see where I am going with this - I have "no idea" of the inherent value of these machines.
As a newbie to this forum, I don't want to be so boring as to bang on about values but the Denford is less interesting to me since it can't do steel. So really I just want to make it work and let it go.
So at the risk of being booted out of the "hello" section: what might I expect to sell an unmodded Denford micromill for and how much is my unmodded VMC190 "worth"?
To get my Boxford, I had to buy a whole bunch of stuff from a school (including a MINT condition Harrison M250) so I don't even know what it's cost me yet! I already have an old Colchester so the lathe also gets sold to fund the Boxford.
