Hi - I've been a lurker on here under another username for quite a while but had to sign up on this username as I'd forgotten my password (and username).

Located in Wellingborough in the UK I'm an electronics engineer specialising in PIC Microcontroller based products.

Back in 1993 I landed a job at a bearings company who had a sideline making 3 axis machines. They ranged from tabletop to huge mahoosive machines capable of carrying a persons weight on the gantry. We visited a couple of CNC fairs while I was there but unfortunately it didn't work out with the company and I left.

Still have the bug though and still have many happy memories of nearly a ton of gantry heading towards me at 6m/s when things went wrong with the servo drives.

Nice to meet you all on here - there seems to be a good community and a knowledgeable range of people on here :)

Heya Picbits

I am new to this too tho have been trying to learn for a long time.

What sort of pic projects do you do? I used to do a fair bit of pic stuff but I could never get into assembly and using a higher language felt like a waste on the ickle pic.

I now use Propeller and SX chips, my main aim for the cnc machine is for pcb's to help make my projects.

Welcome back btw, do you intend to build your own machine?

I mainly build stuff for cars.

I'm currently working on an intelligent relay driver and fan controller - unfortunately summer holidays means I have to look after the kiddie so I cant get a lot of work done (he's got ADHD).

One of my other products is a pulse converter for car dashboards - it samples an input frequency and has an adjustable input-output frequency so you can calibrate your speedometer or use V6 engines on a 4 cylinder rev counter etc.

I am also working on datalogging and display systems for performance vehicles as well as custom programmable gauges/speedo/rev counters etc. Basically you can design your own dashboard from scratch.

I do actually have a 80% built machine - http://www.cnczone.com/forums/showthread.php?t=37790

Unfortunately I had to put the build on hold while I earned some extra pennies to finish it off. Then the summer holidays kicked in ............

I will get it finished off after the holiday as its pretty essential for the machining of the new products I'll be releasing later this year.

p.s. I program exclusively in ASM - never quite got into C but for front end software on the PC I can botch my way through VB.

Hello
I'm newbie too :) and i'm electronic engineer too. I usualy use AVR an ARM processors (c for MCU and Delphi for PC (or c)).
I have built (almost) an easy CNC, now i'me trying to tune it :( It gives now an Z-axis error :)

Still trying to get the time to finish my machine off :(

Its 90% done but every time I put some time aside to get the Z axis finished and some custom drivers built someone rings me offering me money to do some work for them lol.

Actually thinking about it, if I try and get the machine finished every day I'd be rolling in external work and be rich !!!!!
